EmberJS global error when running tests | <p>I am trying to integrate automated testing using Ember Testing.</p>
<p>The application runs fine on browser, without any errors. I tried simply running </p>
<pre><code>ember test
</code></pre>
<p>on command line, but get a bunch of global errors and all the tests fail.</p>
<p>These are the errors I'm getting:</p>
<pre><code>not ok 1 PhantomJS 2.1 - Global error: SyntaxError: Unexpected token ',' at http://localhost:4302/assets/vendor.js, line 145617
not ok 2 PhantomJS 2.1 - Global error: Error: Could not find module ember-metal/core required by: ember-testing/index at http://localhost:4302/assets/test-support.js, line 62
not ok 3 PhantomJS 2.1 - Global error: ReferenceError: Can't find variable: define at http://localhost:4302/assets/tests.js, line 1
...
</code></pre>
<p>When I run the tests on the browser, I do not get the syntax error (first one above), the first error is </p>
<pre><code>Uncaught Error: Could not find module `analogue/resolver` imported from `analogue/tests/helpers/resolver`
</code></pre>
<p>These don't make sense to me since I shouldn't be editing vendor.js and the modules it says it cannot find are there. Any ideas?</p> | 2 |
swift Regular Expression and (.*?) | <p>I want to extract substrings from a string that match a regex pattern.</p>
<p>The problem is this code : <code>("ytplayer.config = {(.*?)};").exec(responseStringC)</code>. It must match but return nil.</p>
<p>string.exec function : </p>
<pre><code>extension String {
func exec (str: String) -> Array<String> {
do {
let regex = try NSRegularExpression(pattern: self, options: [.CaseInsensitive,.IgnoreMetacharacters])
let nsstr = str as NSString
let all = NSRange(location: 0, length: nsstr.length)
var matches : Array<String> = Array<String>()
regex.enumerateMatchesInString(str, options: NSMatchingOptions(rawValue: 0), range: all) {
(result : NSTextCheckingResult?, _, _) in
let theResult = nsstr.substringWithRange(result!.range)
matches.append(theResult)
}
return matches
} catch {
print("error")
return Array<String>()
}
}
}
</code></pre>
<p>"responseStringC" variable is : </p>
<p><a href="http://pastebin.com/uvvq9ULA" rel="nofollow">http://pastebin.com/uvvq9ULA</a></p>
<p>the problem is return nil. Any Clue?</p> | 2 |
VBA Set Excel.Application Object to already open workbook instead of creating a new Excel instance | <p>I use the following all the time to manipulate Excel data from Access.</p>
<pre><code>Set xl = CreateObject("Excel.Object")
</code></pre>
<p>However, this method creates a new Excel instance and only applies formatting, for example, to it.</p>
<pre><code>xl.Range(...).Interior.Color = blah, blah, blah
</code></pre>
<p>Will only refer to that instance of an Excel object that was create with the first line of code.</p>
<p>The problem I am having is that I already have an instance of Excel open and there is VBA in Access that I want to use to apply formatting to the already open file to prep it for importing. I guess I could create the new instance of Excel and just refer to the workbook I am working on with <code>xl.Workbook(blah).Activate</code> but that seems kinda messy.</p>
<p>Yea, I could move the code to Excel, but that defeats the purpose of manipulating Excel from Access and having my VBA in central location accessible to users.</p> | 2 |
Creating many objects in sequence diagram | <p>Suppose I am creating an order handling system. A user may request many different kinds of product for an order. So an order consists of many orderlines. Whenever a customer makes an order the oder object has to create many orderlines objects. How to draw that in sequence diagram? </p> | 2 |
gradle configurations/artifacts only uses "default" configuration | <p>submodule <strong>(locallibs)</strong> build.gradle looks like the following:</p>
<pre><code>configurations.create("default")
artifacts.add("default", file('defaultdistro.aar'))
configurations.create("distro2")
artifacts.add("distro2", file('distro2.aar'))
configurations.create("distro3")
artifacts.add("distro3", file('distro3.aar'))
</code></pre>
<p>the build.gradle for the app has a dependencies{} section that looks like the following:</p>
<pre><code>dependencies {
debugCompile project(':locallibs')
flavor1ReleaseCompile project(path: ':locallibs', configuration: 'distro2')
flavor2ReleaseCompile project(path: ':locallibs', configuration: 'distro3')
}
</code></pre>
<p>The issue I'm having is that regardless of the flavor/build type the "default" configuration is always compiled so all of my flavors are including the "defaultdistro.aar" instead of the correct .aar distro.</p>
<p>I am expecting for flavor1 release build type to compile the distro2.aar but <em>all</em> flavors are compiling the defaultdistro.aar</p>
<p>EDIT: fixed the locallibs build.gradle representation</p>
<p>EDIT #2: the .aar distros are mutually exclusive</p> | 2 |
What is wrong with my XDocument save? | <p>I am trying to save some changes back to an XML file using Linq and I have seen many examples on SO and tutorial sites doing it like this but for some reason I am getting an error on the xmlDoc.Save(customerXMLPath); line <strong>Argument 1: cannot convert from 'string' to 'System.IO.Stream'</strong>. </p>
<p>Most of the samples I have seen are ASP.Net samples but I wouldn't think that should make much a difference on the syntax (this is a UWP app). Can someone please tell me what I am doing wrong?</p>
<pre><code>private void SaveChange_Click(object sender, RoutedEventArgs e)
{
string customerXMLPath =
Path.Combine(Package.Current.InstalledLocation.Path, "XML/Customers.xml");
XDocument xmlDoc = XDocument.Load(customerXMLPath);
var updateQuery = from r in xmlDoc.Descendants("Customer")
where r.Element("CustomerId").Value == txtCustomerId.Text
select r;
foreach (var query in updateQuery)
{
query.Element("State").SetValue(txtState.Text);
}
xmlDoc.Save(customerXMLPath);
}
</code></pre>
<p>Edit: according to the comments there is no overload for Save in UWP. So does that mean (based on another comment) that I have to save as a stream? If that is the case wouldn't I have to overwrite the file? <-- that doesn't make sense when I am just trying to change a few values but maybe I misunderstood the answer. </p>
<p>My assumption is that there is a way to update a XML file in UWP so am I just going about this all wrong? What is the recommended way? By the way SQLite is not an option right now because the files have to remain in XML format </p> | 2 |
How do I compile Qt Application under Manjaro KDE? | <p>Complete noob right here, I'm learning c++ and I saw some tutorial somewhere with instructions to compile the Qt application example from the command line, then I noticed the path from the tutorial was not correct, I want to learn how to compile Qt from command line, and maybe even do some makefiles to automate the process, at least I want to get started ...It seems like the qt libraries are already installed within my system since it is using the KDE desktop environment, but I don't know how should I link or what paths should I include as arguments. Please guide me, remember I'm a complety noob but I really want to learn.
This is the tutorial I'm talking about <a href="http://zetcode.com/gui/qt5/introduction/" rel="nofollow">http://zetcode.com/gui/qt5/introduction/</a></p> | 2 |

Spring Boot applications stop right after start | <p>I had a couple of Spring Boot applications running in my workspace using STS IDE, and right after i did maven update on one of the projects every single one of them stops right after application boot process.

Close Realm instance after execution finishes | <p>I want to close my Realm instance in <code>executeTransactionAsync</code> after execution finished. Reason is that my applications main thread keeps on freezing, I think the reason for it is that the background realm instance is not being closed after execution finishes. See my code below:</p>
<pre><code>realm.executeTransactionAsync(new Realm.Transaction() {
@Override
public void execute(Realm realm) {
// Execute realm code
realm.copyToRealmOrUpdate(myData);
// Can I close the realm instance here without getting an
// error? realm.close(); causes an error.
}
}, new Realm.Transaction.OnSuccess() {
@Override
public void onSuccess() {
Log.i("CB", "success");
// looks like I cannot access the execute Realm
// instance here.
// Closing realm.getDefaultInstance does not change my issue
}
}, new Realm.Transaction.OnError() {
@Override
public void onError(Throwable error) {
Log.i("CB", "error - " + error.getMessage());
}
});
}
</code></pre>
<p>Please see my comments. My application screen just turns black. Execution completes successfully and <code>onSuccess()</code> gets called, but I cannot access the <code>execute</code> realm instance to close it from here. </p>
<p>Do you have any suggestions as to what I can try? Am I doing something wrong?</p>
<p>Thank you in advance.</p>

Material-ui Textfield auto-scroll up the window on first redux-form/FOCUS | <p>I made a form using <a href="https://github.com/erikras/redux-form" rel="nofollow">redux-form</a> with <a href="http://www.material-ui.com/#/components/text-field" rel="nofollow">Textfield</a> from <a href="http://www.material-ui.com/#/" rel="nofollow">material-ui</a> to send an email. Everything is working well except a single thing : When I click on a TextField for the FIRST time, the window scroll uptop. Sometime, the focus stay on the TextField. Afterward it's working fine</p>

<p>The theme imported contain the color used for material-ui style.
I have also found that onFocus and onBlur props of the TextFields doesn't work. I tried to simply log text and it doesn't work. </p>
<p>What makes it even weirder is that it isnt the first time I'm using this emailForm. I used it on another site and it was working perfectly fine.</p>
<p>Anyone has an idea of why it's happening?</p> | 2 |
Similar solutions for java.lang.NoClassDefFoundError: org/joda/time/DateTime not working | <p>I have seen this question posted here before and I have looked at the solutions however I cannot fix the problem I'm having. I created a very simple Maven project in Eclipse for Java and I want to run the output jar file e.g. java -jar jarfilename.jar </p>
<p>I can run the program by right clicking on the project in eclipse and indicating run as Java application. I can build the project to a jar file with mvn package. Running the jar file I get the output of NoClassDefFoundError for the joda time. The joda jar files are in the configured repository e.g. .m2/repository/joda-time/joda-time/2.8.2. There are no errors indicated for the project in Eclipse. I'm using jdk1.8.0_92 Maven version 3.3.9 and eclipse Java EE Neon release 4.6.0. Java home is configured in the environment variables and so too is the class path as: ...\Java\jdk1.8.0_92\jre\lib;C:\Users\username.m2\repository</p>
<p>Some additional information the classpath is correct in terms of not having typos in it. I also looked at a solution from another similar question wherein the suggestion was to add the external jar to the bootstrap entries under run configuratotion. I have also made an entry in the Java build path for joda time which points corretly to the .m2/repository.../joda-time/2.8.2 What this seems like is that when this runs from eclipse the path to the joda time jar file is (for lack of a better term) known. When the jar file is built however that path is not known. I opened the jar file and looked at the MANIFEST.MF file and I see: </p>
<pre><code>Manifest-Version: 1.0
Built-By: John
Class-Path: joda-time-2.8.jar
Build-Jdk: 1.8.0_92
Created-By: Maven Integration for Eclipse
Main-Class: hello.HelloMain
</code></pre>
<p>The source is very simple:
package hello;</p>
<pre><code>import org.joda.time.DateTime;
import org.joda.time.DateTimeZone;
import org.joda.time.format.DateTimeFormat;
public class HelloMain {
public static void main(String[] args) {
System.out.println("Hello From My Main ! It worked\n");
final DateTime today = new DateTime().withZone(DateTimeZone.UTC);
DateTime tommorrow = today.plusDays(3);
String startTime = today.toString(DateTimeFormat.forPattern("yyyy-MM- dd'T'HH:mm'Z"));
String endTime = tommorrow.toString(DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm'Z"));
System.out.printf("The start time %s End Time %s \n", startTime, endTime);
}

Empty override C++11 | <p>Having the Observer pattern.</p>
<pre><code>class Observer
{
virtual eventA()=0;
virtual eventB()=0;
...
virtual eventZ()=0;
}
</code></pre>
<p>The Observer class cannot be changed, but my class is only interested in the event B. Therefore I need to:</p>
<pre><code>class MyObserver{
eventA() override {}
eventB() override { /* Do something */ }
eventC() override {}
...
eventZ() override {}
}
</code></pre>
<p>It is overhead to empty-implement all events, specially if you have a policy to always implement in cpp files (except templates obviously).</p>
<p>Does C++11 offer any keyword for that? Like</p>
<pre><code>...
eventC() override = empty;
...
</code></pre>
<p>In that way, I wouldn't need to add the empty implementation in the CPP file.</p> | 2 |
ASP.NET Core fails to start in debug mode when SSL is enabled | <p>I'm getting the following error while launching debugger (F5) in Visual Studio:</p>

Accessing ngModel elements that use a class | <p>I have many elements in my HTML code that have their <code>ngModel</code> assignment defined as <code>ng-model = "object.[something]"</code>.</p>
<p>For example: </p>
<p><code><div class="form-group row" ng-model="object.askUser"></code></p>
<p>I do this to be clear of my purpose for these elements. My question is how do I access these element in my Javascript? Do I call <code>$scope.object.askUser</code>, <code>$object.askUser</code>, or something else? I had a hard time finding things on the web about this, most likely because I wasn't quite sure of the words to use in the search bar to describe what I am trying to do.</p> | 2 |
How to "reset" a DOM subtree's CSS style? | <p>I'm developing a Chrome Extension, an HTML subtree and a CSS style sheet are injected into the original page. I want the injected HTML subtree not to be affected by the original CSS, but I have no idea about how to finish the job perfectly. The problem:</p>
<pre><code><!DOCTYPE html>
<style>
/* original CSS */
input[type="text"] {
background: green;
}
input[type="text"]:focus {
background: yellow;
}
/* my injected CSS somewhere else */
.injected-root input[type="text"] {
border: solid 1px navy;
}
</style>
<input type="text" value="original text">
<div class='injected-root'>
<input type="text" value="injected text">
</div>
</code></pre>
<p>The original page is a random page on the internet, so it's impossible to know what the original CSS would be. As you can see from the code above, my injected text input is affected by the original CSS, I know it can be fixed by override the original CSS with new default values:</p>
<pre><code>.injected-root input[type="text"] {
border: solid 1px navy;
background: white;
}
.injected-root input[type="text"]:focus {
background: white;
}
</code></pre>
<p>But I don't think it's feasible to do it "manually" by supply every default attribute.</p>
<p>So, the question is: </p>
<ul>
<li><strong>Is there a way to reset the style of a subtree completely?</strong></li>
</ul>
<p>or</p>
<ul>
<li><strong>Any other strategy to make the subtree seems in an "isolated universe" (only affected by its own injected CSS)?</strong></li>
</ul> | 2 |

Daylight saving time with NSTimeZone best practice | <p>I have created a weekly view(similar to calendar) with header day of week. I am creating the current time using below code :</p>
<pre><code>+(NSDate *) getCurrentDate {
NSDate* datetime = [NSDate date];
NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:@"America/Juneau"];// this is dynamic and coming from server.
[dateFormatter setTimeZone:timeZone]; // Prevent adjustment to user's local time zone.
[dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"];
NSString* dateTimeInIsoFormatForUserTimeZone = [dateFormatter stringFromDate:datetime];
return [dateFormatter dateFromString:dateTimeInIsoFormatForUserTimeZone];
}
</code></pre>
<p>I am using this date as reference to create week date (from monday to sunday). My code work fine for all case but I was failing at DST time zone.</p>
<p>I have seen similar question on stack-overflow but they are more subjective and not able to solve my problem. Answer with code and best practise is highly appreciated. Thanks In advance!. </p> | 2 |
Why are map values not addressable? | <p>While playing with Go code, I found out that map values are not addressable. For example,</p>
<pre><code>package main
import "fmt"
func main(){
var mymap map[int]string = make(map[int]string)
mymap[1] = "One"
var myptr *string = &mymap[1]
fmt.Println(*myptr)
}
</code></pre>
<p>Generates error</p>
<blockquote>
<p>mapaddressable.go:7: cannot take the address of mymap[1]</p>
</blockquote>
<p>Whereas, the code,</p>
<pre><code>package main
import "fmt"
func main(){
var mymap map[int]string = make(map[int]string)
mymap[1] = "One"
mystring := mymap[1]
var myptr *string = &mystring
fmt.Println(*myptr)
}
</code></pre>
<p>works perfectly fine.</p>
<p>Why is this so? Why have the Go developers chosen to make certain values not addressable? Is this a drawback or a feature of the language?</p>
<p><strong>Edit</strong>:
Being from a C++ background, I am not used to this <code>not addressable</code> trend that seems to be prevalent in Go. For example, the following code works just fine:</p>
<pre><code>#include<iostream>
#include<map>
#include<string>
using namespace std;
int main(){
map<int,string> mymap;
mymap[1] = "one";
string *myptr = &mymap[1];
cout<<*myptr;
}
</code></pre>
<p>It would be nice if somebody could point out why the same <em>addressability</em> cannot be achieved (or intentionally wasn't achieved) in Go.</p> | 2 |

<p>I get a value here when used caml query with FSObjType is 1 which is for only folders... but unfortunately i get null when query with FSObjType is 0 which queries only files. My requirement is to get a value even when you are at the file level... Not sure if i'm going correct with the CAML query..</p>

MySQL load data infile is slow | <p>I'm new to SQL, and I see this question has been asked many times, but none of the answers have helped me. So I'm hoping to get feedback on my situation.</p>
<p>I am trying to load a tab-delimited file with about 1.5 million rows and 48 columns. Each field is enclosed with double quotes. My query ran for over an hour and I killed it. Here is what I did:</p>
<pre><code>CREATE TABLE mytable (
*48 variable declarations given types varchar, int, or decimal*,
PRIMARY KEY (id)
);
</code></pre>
<p> </p>
<pre><code>load data local infile 'MyFile.tsv'
into table mytable
fields terminated by '\t'
enclosed by '"'
lines terminated by '\n' IGNORE 1 LINES
(*comma separated list of all 48 variable names in 'mytable'*);
</code></pre>
<p>Is there something obviously that I'm missing that is blowing up the runtime of this query? I was careful to declare variables with only enough space as needed. So if I have an integer field with up to 3 digits, it is declared as <code>myfield int(3)</code>.</p> | 2 |

hardware transactional memory: _xbegin() return 0 | <p>By gcc docs: <a href="https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/X86-transactional-memory-intrinsics.html" rel="nofollow">x86-transactional-memory-intrinsics.html</a>, when transaction failed/abort, <strong>_xbegin()</strong> should return a <strong>abort status</strong> .

YOLO neural network not compiling in VS13 | <p>I'm trying to use <a href="http://pjreddie.com/darknet/yolo/" rel="nofollow">YOLO</a> in VS13, but it's not compiling.

If I use opencv 2.4.13, the error is </p>
<pre><code>Error 1075 error LNK1104: cannot open file 'opencv_core249.lib'
</code></pre>
<p>(downloading this lib not helping and causes another linker error)</p>
<p>If I use opencv 3.1.0 this error accures</p>
<pre><code>Error 14 error : this declaration may not have extern "C" linkage C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\limits 78 1 darknet

<p>I found <a href="https://groups.google.com/forum/#!searchin/darknet/opencv$203/darknet/AfZcD-C6yXY/RWp5V2tXBAAJ" rel="nofollow">solution</a> which didn't work for me, because if i remove </p>

#include "opencv2/imgproc/imgproc_c.h"
#endif
</code></pre>
<p>from image.h, and add it to image.c (generally it's already in image.c, so i'm just deleting this lines from image.h) the error accures in this lines (image.h)</p>
<pre><code>#ifdef OPENCV

image get_image_from_stream(CvCapture *cap);
image ipl_to_image(IplImage* src);

<p>(CvCapture and IplImage not defined)</p>
<p>So, how can I use YOLO in windows? What should I fix in frischzenger or AlexeyAB solution?</p> | 2 |
Log python on Openshift | <p>I have configured my Django project on Openshift with success.</p>
<p>But somewhere in my site I launch a command tool installed by <strong>pip</strong> and I think the command failed.
But I don't find python log with</p>
<pre><code>rhc tail -a project
</code></pre>
<p>Or when I got to <strong>/var/lib/openshift/<em>id</em>/app-root/logs/python.log</strong> file I don't find more log than displayed at screen</p>
<p><strong>How can I see all my python output console ?</strong></p>
<p>Thanks</p>
<p><strong>[EDIT]</strong> </p>
<p>I tried to use the <a href="https://docs.djangoproject.com/en/1.8/topics/logging/#examples" rel="nofollow">logging configuration for django</a>, but I can't see my log even if I put my app name in <strong>loggers</strong>.</p> | 2 |
Polymorphic Associations in Entity Framework | <p>I have a legacy database that has a few tables which were designed using <a href="https://stackoverflow.com/questions/2002985/mysql-conditional-foreign-key-constraints">Polymorphic Associations</a>. By polymorphic associations, I mean that those tables can be child of different tables according to a column <code>ObjectType</code>. </p>
<p>Example: </p>
<ul>
<li><code>Documents</code> table has <code>DocumentID</code> (identity primary key), some other columns, and 2 special columns called <code>ObjectType</code> and <code>ObjectID</code>. </li>
<li>If <code>ObjectType='STUDENT'</code>, <code>ObjectID</code> points to <code>Students</code> table. </li>
<li>If <code>ObjectType='TEACHER'</code>, <code>ObjectID</code> points to <code>Teachers</code> table, etc. </li>
</ul>
<p>This is similar to <a href="https://stackoverflow.com/questions/7000283/what-is-the-best-way-to-implement-polymorphic-association-in-sql-server">this design</a> (as described in the "no foreign key approach") or <a href="https://stackoverflow.com/questions/3894056/how-do-i-apply-subtypes-into-an-sql-server-database">this one</a> (described as an anti-pattern). And obviously, there are <strong>no foreign key constraints</strong> on those columns <em>(AFAIK no database would allow that kind of relationship)</em>.</p>
<p>I'm writing a new Data Access Layer using Entity Framework 6 (code-first with Fluent API) which should work side-by-side with existing code. Since this database structure was deployed to hundreds of different customers (each one with a different codebase and different database customizations), modifying the structure of existing tables is not an option.</p>
<p>My question is: How do I map those Polymorphic Associations into my EF code-first model?</p>
<hr>
<p><strong>EDIT</strong>: It seems that I was trying to design the class hierarchy on the wrong entities. My understanding was that I had a lot of "GenericChildTables" (like Documents) that should point to a (non-existing) entity that would have a composite key ObjectType+ObjectID. And then I was trying to create that new entity (let's call it "BusinessObject") and map my core entities (Students, Teachers, etc) to be subtypes of this BusinessObject. </p>
<p>THAT design was probably just plain wrong, and maybe totally impossible because this new table that I was creating (BusinessObject) depended on StudentID/TeacherID, etc, so it couldn't be a parent of those tables. Using some ugly workarounds I could create that BusinessObject as a single-child for each core entity, and map those BusinessObjects to the polymorphic tables, and it was working indeed but in a completely wrong design. </p>
<p><strong>Then</strong> I saw <a href="https://stackoverflow.com/questions/13953675/modelling-polymorphic-associations-database-first-vs-code-first">Gert Ardold's question</a> and realized that what should be designed as a class hierarchy was NOT Students/Teachers/etc (grouped into a generic entity), but each one of those ChildTables, which were holding different subtypes according to the <code>ObjectType</code> discriminator - those were the types that should be splitted into subtypes. <strong>See my solution on my own answer below.</strong></p> | 2 |

How to add multiple wp_editor in single page | <p>I tried to add multiple wp_editor() in single page and it shows, but when I tried to add media, the media button is not working and I added the option (drag_drop_upload to true) to wp_editor option to make drag and drop and its worked.</p>
<p>But when I drag and drop the image, all the images are inserting in the first wp_editor instance. Even I tried to drag and drop in second or third wp_editor, but it again displaying in the first editor.</p>
<p>Is there any solution to insert the media either by uploading or drag and drop to the particular wp_editor instance?</p>

Run next in "foreach" only once previous finished in javascript | <p>It might be smth simple, but I just cannot find the way to do it.
I have an array, and I want to do a few actions for each array value BUT only once the previous is finished.
Lets say I have an array [1,2,3,4,5] and I want to add img tag with a picture with the name "picture"+i+".jpg" ,if picture file doesnt exist - use default picture, do few more actions with that img and, only once its all done, do the next "foreach".</p>
<p>I am looking into promises but still cannot figure it out.
Problem is that its not just one async action (ajax or get) but a few different actions.</p>
<p>Thanks</p> | 2 |
Django - complex calculations in the template | <p>As far as I understand, there's no way to do math including django variables in the template, for example</p>
<pre><code><td>{{variable_1}} + {{variable_2}}</td>
</code></pre>
<p>People recommend to do the calculations in the views, but my concern is that we should use servers-side just to transmit data from server to client - that's it. All the calculations should be done using client computer power. The other option might be doing calculations in javascript, particularly jquery, after the page load, but the downside is that data is rendered with a lag in those cases when calculations are very complex. What is the best practice here and most balanced soltion ? </p> | 2 |
Enable/Disable Delete Button with Javascript | <p>I am having an issue with Enabling a button with a checkbox using JavaScript. Whenever I click the checkbox, the Delete button stays disabled.</p>
<p>The code I am using is as follows:</p>
<pre><code><script type="text/javascript">
$('#cb_delete').click(function(){
if($(this).attr('checked') == false){
$('#btn-delete').attr("disabled","disabled");
}
else {
$('#btn-delete').removeAttr('disabled');
}
});
</script>
<button type='submit' name='btn-delete' disabled='disabled' id='btn-delete' class='btn btn-default btn-sm'>Delete</button>
<td><input type='checkbox' name='cb_delete[]' id='cb_delete' value='$mID'></td>

ng-click doesn't work when open link in new tab is clicked | <p><code>ng-click</code> and <code>ng-href</code> directives when used together will first execute click function. In the following example navigation to Google will be prevented and alert will be shown.</p>
<pre><code><a ng-href='http://google.com' ng-click="click($event)">Link</a>
$scope.click = function (event) {
event.preventDefault();
alert('click has been trigerred');
}
</code></pre>
<p>This will work though only when user clicks a link using left mouse button. If user will try to open the link in a new tab the click event won't be triggered. To some extent it seems correct because it's not strictly speaking "click", but is there any Angular directive for handling opening link in the new tab?</p>
<p><strong>UPDATE:</strong></p>
<p>I don't want to open new tab programatically, but handle event of opening new tab by the user.</p> | 2 |
Why its not recommended to pass object to fragment with simple getter setter | <p>I'm new to android, I wonder why this easy method for parameter passing is not recommended.</p>
<pre><code>class DemoFragment extends Fragment{
private MyObject myObject;
public void setMyObject(MyObject myObject){
this.myObject = myObject;
}
}
DemoFragment fragmentDemo = new DemoFragment();
fragmentDemo.setMyObject(myObject);

Import PowerShell Module from C# Failing | <p>I have seen quite a number of solutions, but none addresses my problem.
I am trying to import a custom PowerShell module called "DSInternals" to my C# DLL.</p>
<p><a href="https://github.com/MichaelGrafnetter/DSInternals" rel="nofollow">https://github.com/MichaelGrafnetter/DSInternals</a></p>
<p>Everything in my code seems just fine, but when I try to get the available module it's not loaded.</p>
<p>The stream responds with</p>
<blockquote>
<p>The term 'Get-ADReplAccount' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.</p>
</blockquote>
<p>Where Am I going wrong with this code?</p>
<pre class="lang-cs prettyprint-override"><code>InitialSessionState init = InitialSessionState.CreateDefault();
init.ImportPSModule(new string[] { @"D:\\DSInternals\\dsinternals.psd1" }); //location of the module files
Runspace runspace = RunspaceFactory.CreateRunspace(init);
runspace.Open();
PowerShell ps = PowerShell.Create();
ps.Runspace = runspace;
ps.Commands.AddCommand("Get-ADReplAccount"); //this command is un-recognized
foreach (PSObject result in ps.Invoke())
{
Console.WriteLine(result); //this always returns null

finding modulus of huge numbers in java | <pre><code> for(i=0; i<n+1; i++)
{
y=y+(a[i]*(int)Math.pow(j,i));
}
int r=y/786433;
s[k]=y-(r*786433);
k++;
</code></pre>
<p>Now in this code the <code>j</code> value can be <code>786432</code>. So when I try to get modulus of a number say <code>(1+2*(786432)^2+3*(786432)^3)%786433</code> then I get <code>-521562</code> which is not correct I was using modulus operator before too but I got the same answer even with this approach I am getting the same answer. In this approach the modulus of the number is stored in array <code>s[k]</code>. Can anyone help?</p> | 2 |
Error when settingDBus property | <p>I'm trying to set a property of a DBus Interface with Qt5.7.0.
This is the doc:</p>
<p><a href="http://git.kernel.org/cgit/network/ofono/ofono.git/tree/doc/modem-api.txt" rel="nofollow">http://git.kernel.org/cgit/network/ofono/ofono.git/tree/doc/modem-api.txt</a></p>
<p>and I want to set the <code>Powered</code> property to <code>true</code>.
Here my code:</p>
<pre><code>QDBusInterface *iface = new QDBusInterface("org.ofono", "/hfp/org/bluez/hci0/dev_xx_xx_xx_xx_xx_xx", "org.ofono.Modem", QDBusConnection::systemBus());
iface->call("SetProperty", "Powered", QVariant(true));
</code></pre>
<p>and this is the error:</p>
<blockquote>
<p>QDBusError("org.freedesktop.DBus.Error.UnknownMethod", "Method "SetProperty" with signature "sb" on interface "org.ofono.Modem" doesn't exist")</p>
</blockquote>
<p>The path comes from the <code>GetModem</code> method and it's correct.
Also, I tried the same with Python:</p>
<pre><code>modem = dbus.Interface(bus.get_object('org.ofono', '/hfp/org/bluez/hci0/dev_xx_xx_xx_xx_xx_xx'), 'org.ofono.Modem')
modem.SetProperty('Powered', dbus.Boolean(1))
</code></pre>
<p>and it works fine! So the problem is definitely related to my Qt5 code.
How to better understand the error message? Is wrong my signature or it doesn't find the <code>SetProperty</code> method at all?</p> | 2 |

Pango Color Glyphs | <p>I am working on a project that uses the following technology to render text:</p>
<ul>
<li>Freetype - Glyph mapping</li>
<li>Pango - Text Layout</li>
<li>Skia - Drawing (font color and graphics for rest of system)</li>
</ul>
<p>We are now trying to add the ability to render colored emoji. Right now it seems that Freetype added the support to specify color glyphs but we have been having issues getting Pango to layout colored font. Is it even possible to render color emoji this way? If we switched from Skia to Cairo would that help?</p>
<p>Similarly, I have taken this small example <a href="https://developer.gnome.org/pango/stable/pango-Cairo-Rendering.html" rel="nofollow noreferrer">https://developer.gnome.org/pango/stable/pango-Cairo-Rendering.html</a> and tried to use emoji instead of text and I am not getting the glyph to show even though the font specified is "Apple Color Emoji".</p>

<p>This is a fairly trivial process in Photoshop, but this is a process I'd like to repeat frequently, ideally without making a black fill picture for each object I'd like to do it for. I've tried several edge detecting classes but found no success.</p>

Adview from Admob shows blank box if no Internet connection | <p>I just tried to include an Adview in my layout. Works just fine, except that it shows a blank space if there is no Internet connection. As I have read so far, I understand that the standard behaviour for an admob is to take space only if the Ad is shown. Otherwise, eg. no Internet connection, it should take no layout space. I'm listing the code where I think I might have made a mistake and that's why I encounter this odd behaviour...</p>

How could I access the source code of a .one OneNote file? | <p>How could I access the source code of a .one OneNote file?</p>
<p>I've tried to rename the .one file to .zip as what happens with .doc files in order to access their source code, but .one doesn't seem to work like that.
Also, I've tried to open it with Notepad++, but it isn't in a plain-text format.</p>
<hr>
<p><em>I regard this as a programming question because:
I'm using content-editing-automation scripts (e.g. RegEx-related find and replace scripts). Accessing the source code of .one files helps me apply bulky automated edits on their content Using RegEx.</em></p> | 2 |

LLDB 'thread return' command emits error in a Swift function | <p>I am reading the <a href="https://www.objc.io/issues/19-debugging/lldb-debugging/" rel="noreferrer">Dancing in the Debugger — A Waltz with LLDB</a> article.

How to mock/stub activate() method in AngularJS application | <p>I'm currently working on a large AngularJS application, very much based on the excellent <a href="https://github.com/johnpapa/angular-styleguide/tree/master/a1" rel="nofollow">AngularJS Styleguide by John Papa</a>.</p>
<p>One of his recommendations is the use of an <code>activate()</code> method as a sort of bootstrapper for every controller. This makes your code structure clear and you immediately know where bootstrapping begins. Often times, I use it to load data (I prefer this over route-resolves).</p>
<p>The problem I'm facing is how should I unit-test the <code>methodUnderTest()</code>-method in the below code example without running the <code>activate()</code>-method.</p>
<pre><code>(function() {
'use strict';
angular
.module('myApp', [])
.controller('ControllerUnderTest', ControllerUnderTest);
ControllerUnderTest.$inject = [];
/* @ngInject */
function ControllerUnderTest() {
var vm = this;
// attach functions to vm
vm.activate = activate;
vm.methodUnderTest = methodUnderTest;
// activate
activate();
function activate() {
// controller start-up logic
}
function methodUnderTest() {
// how to test this method, without running the activate() method
}
})();
</code></pre>
<p>Below is the test-code I currently have, but as you would expect it will always run the <code>activate()</code> method (which is not what I want).</p>
<pre><code>(function() {
var scope, createController;
beforeEach(module('myApp'));
describe('ControllerUnderTest', function(){
beforeEach(inject(function($rootScope, $controller) {
scope = $rootScope.$new();
createController = function() {
return $controller('ControllerUnderTest', { 'scope': scope });
};
}));
it('should be defined', function() {
var controller = createController();
expect(controller).toBeDefined();
});
it('should have a methodUnderTest', function() {
var controller = createController();
expect(controller.methodUnderTest).toBeDefined();
});
});
})();
</code></pre>
<p>How do I test <code>ControllerUnderTest.methodUnderTest()</code> without running the <code>activate()</code> method?</p> | 2 |

Bind the progress of a query to a progressProperty of a ProgressBar for informing the user of download and upload time in javaFX? | <p>I got an app that upload and download images to a mysql database but this take like 5 secs and i want to tell the user the progress of this </p>
<p>i do the transactions in a task here is the code</p>
<pre><code> // progres bar indefinit
progressBar.setProgress(-1);
Task<Void> task = new Task<Void>() {
@Override
protected Void call() throws Exception {
try {
//i net to put to sleep the javafx thread for making a connection
Thread.sleep(10);
} catch (InterruptedException ex) {
ex.printStackTrace();
}
Platform.runLater(new Runnable(){
public void run(){
//Coneccts to the data base
try(Connection conexionInterna = dbConn.conectarBD()) {
//Get the object from the data base

if (rayosVacio!=null) {
//sets the image if exists
imageView.setImage(rayosVacio.getIma__imaRay());
}else
//sets the defauld image
imageView.setImage(Nohay);
} catch (SQLException e) {
e.printStackTrace();
}
}
});
return null;
}
};
task.setOnSucceeded(new EventHandler<WorkerStateEvent>() {
@Override
public void handle(WorkerStateEvent event) {
//sets the progress bar in the final to complete
progressBar.setProgress(100);
}
});
Thread tt = new Thread(task);
tt.setDaemon(false);
tt.start();
</code></pre>
<p>with that code i make a intermittent progressBar but this is not what i looking for, looking to have the best UX i think the best is for demonstrate the progress</p>
<p>to do this it i think i have to know how many bytes are been transferred for the database to the pc but i dont know how to obtain this information</p>
<p>here is how i download images from the database</p>
<pre><code> public imagenrayos cargaSolaUnResultado(String dato, Connection conex){
imagenrayos im = null;
String sqlSt = "SELECT `id_imaRay`,\n" +
"`ima__imaRay`,\n" +
"`id_rayos` \n"+
"FROM imagenrayos\n" +
"WHERE id_rayos = '"+dato+"';";
try(PreparedStatement stta = conex.prepareStatement(sqlSt);
ResultSet res = stta.executeQuery()){
if (res.next()) {
byte[] data = res.getBytes("ima__imaRay");
BufferedImage img = ImageIO.read(new ByteArrayInputStream(data));
Image image = SwingFXUtils.toFXImage(img, null);
im = new imagenrayos( res.getString ("id_imaRay"),
image,
res.getString ("id_rayos"));
}
} catch (SQLException | IOException ex) {
ex.printStackTrace();
}
return im;
}
</code></pre>
<p>with this i believe i can obtain the size of image an set my 100% target</p>
<pre><code>byte[] data = res.getBytes("ima__imaRay");
int sizeofImage = data.length;
</code></pre>
<p>but here is my doubt, how to track the progress of the data transferred? this is the way or there are better options for making the information available for the user ?</p>
<p><strong>EDIT</strong></p>
<p>I found a way in Android to do this but i don't see how to implement in my case here is the Android Solution </p>

<p>the key here will be how to put the progress of the SQL query inside of a while and there use the <code>updateProgress();</code> method of task to bind this value to the progressProperty of the progressBar in something like this</p>
<pre><code>progressBar.progressProperty().bind(task.progressProperty());

Using PHP to Search and Replace POST vars in docx document | <p>I am trying to do a search and replace on a Microsoft Word docx document. The odd problem I am having is that, of the 7 posted vars, 1 and 5 do not replace. In checking Chrome Tools, they all appear in the posted form data. The names are all spelled correctly too. </p>
<p>To explain this code, I am opening a template doc, copying it to another name (the named file which will be downloaded), replacing text in document.xml, then replacing text in the footer. Then I close the file and download it. It downloads, except, the vars $pname and $hca2name do not replace inside of the document. All other vars are properly replaced.</p>
<p>Any thoughts are very much appreciated. Thank you. Here is the code:</p>
<pre><code><?php
$pname = (string) $_POST['pname'];
$countyres = (string) $_POST['countyres'];
$a1name = (string) $_POST['a1name'];

$hca1name = (string) $_POST['hca1name'];
$hca2name = (string) $_POST['hca2name'];
$atty = (string) $_POST['atty'];
$countyres = (string) $_POST['countyres'];
$fn = 'POA-'.$pname.'.docx';
$s = "docs_archive/PA-poas2no.docx";

Use Calendar to get the number of days in February | <p>The question is to get day numbers of February of any year. My code is like this:</p>
<pre><code>public static void main(String[] args) {
System.out.println("2014-02 has " + getDaysOfFeb(2014) + "days");
System.out.println("2016-02 has " + getDaysOfFeb(2016) + "days");
}
public static int getDaysOfFeb(int year) {
Calendar c = Calendar.getInstance();
// set year-01-31
c.set(year, 0, 31);
long lastDayofJan = c.getTimeInMillis();
// set year-03-01
c.set(year, 2, 1);
long firstDayOfMar = c.getTimeInMillis();
int date = (int) ((firstDayOfMar - lastDayofJan) / 1000 / 60 / 60 / 24);
}
</code></pre>
<p>I got <code>Jan 31st</code> and <code>Mar 1st</code>, I use the difference of time to calculate the day numbers. But the result is:</p>
<pre><code>2014-02 has 29days
2016-02 has 30days
</code></pre>
<p>I don't understand why.</p>
<p>When I do like this:</p>
<pre><code>public static int getDaysOfFeb(int year) {
Calendar c = Calendar.getInstance();
// set year-01-31
c.set(year, 2, 1);
c.add(Calendar.DATE, -1); // last day of Feb
int date = c.get(Calendar.DATE);
return date;
}
</code></pre>
<p>The result is right, as follow:</p>
<pre><code>2014-02 has 28days
2016-02 has 29days
</code></pre>
<p>Does anyone know what the difference is here?</p> | 2 |
Concatenate string members using Linq PredicateBuilder for text search | <p>I have a REST WebAPI using <code>EntityFramework</code> database first. All code is generated off the <code>EDMX</code> file, entities, repository classes and API controllers etc.</p>
<p>I have added some filtering functionality which allows users to add conditions via the query string that translate to <code>LinqKit PredicateBuilder / Linq</code> expressions that filter results when hitting the db.</p>
<pre><code>e.g. /api/Users?FirstName_contains=Rog
</code></pre>
<p>This will return all users with 'Rog' in the <code>User.FirstName</code> member. This uses <code>PredicateBuilder</code> to dynamically build an appropriate <code>Linq</code> expression to then use as a <code>Where</code> clause against the <code>DbSet</code>. </p>
<p>For example:</p>
<pre><code>var fieldName = "FirstName";
var value = "Rog";
var stringContainsMethod = typeof(string).GetMethod("Contains", new[] { typeof(string) });
var parameter = Expression.Parameter(typeof(User), "m");
var fieldAccess = Expression.PropertyOrField(parameter, fieldName);
var fieldType = typeof(User).GetProperty(fieldName, BindingFlags.IgnoreCase | BindingFlags.DeclaredOnly | BindingFlags.Instance | BindingFlags.Public).PropertyType;
var expression = Expression.Lambda<Func<User, bool>>(Expression.Call(fieldAccess, stringContainsMethod, Expression.Constant(value, fieldType))
, parameter)
var andPredicate = PredicateBuilder.True<User>();
andPredicate = andPredicate.And(expression);
var query = Db.Users
.AsQueryable()
.AsExpandable()
.Where(andPredicate);
</code></pre>
<p>Now the problem. I want the client to be able to match results based on a composition of members. </p>
<pre><code>e.g. /api/Users?api_search[FirstName,LastName]=Rog
</code></pre>
<p>i.e. search <code>first name + last name</code> for matches of 'Rog', so I could search for 'Roger Sm' and get a result for first name = Roger and last name = Smith.</p>
<p>If I was to query the <code>DbSet</code> using fluent it would look like:</p>
<pre><code>users.Where(u => (u.FirstName + " " + u.LastName).Contains("Rog"));
</code></pre>
<p>What I am struggling with is creating a <code>predicate / linq</code> expression that will handle the concatenation of string members <code>FirstName + " " + LastName</code> dynamically.</p> | 2 |

Calico NetworkPlugin cni failed on the status hook for pod 'nginx' - invalid CIDR address: Device "eth0" does not exist | <p>I have the following kubelet error on my minions:</p>

Set breakpoint in Racket? | <p>Using Emacs/geiser with Racket (not DrRacket), how could I set a breakpoint and then step through the code, halting at breakpoint(s)? For example, I've got this code:</p>
<pre><code>(define (powerset4 lst)
(if (null? lst)
'(())
(append-map (lambda (x)
(begin
(fprintf (current-output-port) "~s ~s ~s\n" x lst x)
(list x (cons (car lst) x))))
(powerset4 (cdr lst)))))
</code></pre>
<p>and I want to stop inside the <code>begin</code> sequence to see what's happening and what the values are. It would also be nice to not rely on ye 'ol <code>printf</code> tricks either, i.e., track certain parameters as well. Again, I'm in Emacs and using Geiser. Actually, I'd switch to Guile or Chicken (Geiser languages) if I could do this better with them.</p> | 2 |
Java: add to map of collections | <p>I'm trying to write a generic function that will add an element to a <code>Map</code> of <code>Collection</code>s. This works for a <code>Map</code> of <code>List</code>s:</p>
<pre><code>public static <TKey, TVal> void addToMapOfLists(Map<TKey, List<TVal>> map, TKey key, TVal val) {
List<TVal> list = map.get(key);
if (list == null) {
list = new ArrayList<>();
list.add(val);
map.put(key, list);
} else
list.add(val);
}
</code></pre>
<p>I want to make this function work on <code>Map<TKey, Set<TVal>></code> as well as on <code>Map<TKey, List<TVal>></code>. I expect this should be possible because both implement <code>Collection</code> that has the <code>add(TVal)</code> member that I call.</p>
<p>My problem is that when I try change the parameter <code>Map<TKey, List<TVal>> map</code> to <code>Map<TKey, ? extends Collection<TVal>> map</code> - I need to somehow replace <code>new ArrayList<>();</code> with a call to the constructor of the implementer of <code>Collection</code>.</p> | 2 |

Getting a Column on the next Row on excel with Macro | <p>i need as the title says to put the data from a column onto the next row.
After a lot of research i learned that it can be done using macros and this is where i need your help.</p>
<p>Example of what i need to do:</p>
<p>What i mean is that i have an excel doc with 4 columns</p>
<pre><code> A B C D
1 Data1 Data2 Data3 Data4
2 Data5 Data6 Data7 Data8
</code></pre>
<p>I want every D column data to go to the next line like this.</p>
<pre><code> A B C
1 Data1 Data2 Data3
2 Data4 // First Data of D column on below line moved on line 2
3 Data5 Data6 Data7
4 Data8 // Second Data of D column on below line moved on line 4.
</code></pre>
<p>So i recorded a macro of adding a line on "2" and cuttin-paste the first D on the new 2. The code is this:</p>
<pre><code>Sub Data1()
'
' Data1 Macro
'
'
'
ActiveCell.Offset(1, 0).Range("A1:D1").Select
Selection.EntireRow.Insert , CopyOrigin:=xlFormatFromLeftOrAbove
ActiveCell.Offset(-1, 3).Range("A1").Select
Selection.Cut
ActiveCell.Offset(1, -3).Range("A1").Select
ActiveSheet.Paste
End Sub
</code></pre>
<p>Result: </p>
<p><a href="https://i.stack.imgur.com/Ez0Ni.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Ez0Ni.png" alt="https://s32.postimg.org/xqofxu1lh/Work1.png"></a></p>
<p>The thing is that with a lot of data that needs to be run a lot of times so a loop is really needed here.</p>
<p>Tried using a loop but iam stack here and there is where i need your help</p>
<p>Thats how far iam but it doesnt work now as it should.</p>
<pre><code>Dim x As Integer
Sub Data1()
'
' Data1 Macro
'
'
'
x = 1
Do While x <= 20 ' that i will change as how many columns i have.
ActiveCell.Offset(x, 0).Range("A1:D1").Select
Selection.EntireRow.Insert , CopyOrigin:=xlFormatFromLeftOrAbove
ActiveCell.Offset(x - 2, x + 2).Range("A1").Select
Selection.Cut
ActiveCell.Offset(x, x - 4).Range("A1").Select
ActiveSheet.Paste
x = x + 2 ' if it starts from cell no1 and we have a blank to fill with Data4 or Data8 of D row then we need x+2 i believe and not x+1.
Loop
End Sub
</code></pre>
<p>Result with lots of data and 2nd modified (not working) code:</p>

Extension Methods and method overriding | <p>The other day I found this statement in a stackoverflow post relating to Extension Methods:</p>
<blockquote>
<p>The main thing there is ability to override different methods based on different generic’s parameters instantiation. This is similar to Haskell’s type classes</p>
</blockquote>
<p><a href="https://stackoverflow.com/questions/4359979/java-equivalent-to-c-sharp-extension-methods/27785184#27785184">Java equivalent to C# extension methods</a></p>
<p>What's that supposed to mean? Can anybody give a significant example which clarifies this statement?</p> | 2 |
QTcpSocket delay/buffering issue | <p>I have two instances of my Qt application communicating via QTcpSockets</p>
<p>Some packets get stuck and are not received until the next packet is sent. This happens even if the next packet is sent several minutes after. So it seems there is some buffering which has no timeout.</p>
<p>I have tried QTcpSocket::flush() on the sender, without success. This happens with one Qt build (5.6.1) and not with another (5.4.2). Both are built with MinGW-w64 (Windows platform)</p>
<p>When I say the packet is not received, I mean that bytesAvailable() stays at zero (I have checked with a polling timer for debugging). readyRead() is never emitted as well.</p>
<p>For instance, I'm sending packet A and packet B just after. Then, I send packet C two minutes later. The receiver gets a complete packet A, but no packet B, and the socket has no bytes available for reading. When packet C is sent, I receive packets B and C.</p> | 2 |

Python 2.x - sleep call at millisecond level on Windows | <p>I was given some very good hints in this forum about how to code a clock object in Python 2. I've got some code working now. It's a clock that 'ticks' at 60 FPS:</p>
<pre><code>import sys
import time
class Clock(object):
def __init__(self):
self.init_os()
self.fps = 60.0
self._tick = 1.0 / self.fps
print "TICK", self._tick
self.check_min_sleep()
self.t = self.timestamp()
def init_os(self):
if sys.platform == "win32":
self.timestamp = time.clock
self.wait = time.sleep
def timeit(self, f, args):
t1 = self.timestamp()
f(*args)
t2 = self.timestamp()
return t2 - t1
def check_min_sleep(self):
"""checks the min sleep time on the system"""
runs = 1000
times = [self.timeit(self.wait, (0.001, )) for n in xrange(runs)]
average = sum(times) / runs
print "average min sleep time:", round(average, 6)
sort = sorted(times)
print "fastest, slowest", sort[0], sort[-1]
def tick(self):
next_tick = self.t + self._tick
t = self.timestamp()
while t < next_tick:
t = self.timestamp()
self.t = t
if __name__ == "__main__":
clock = Clock()
</code></pre>
<p>The clock does not do too bad, but in order to avoid a busy loop I'd like Windows to sleep less than the usual about 15 milliseconds. On my system (64-bit Windows 10), it returns me an average of about 15 / 16 msecs when starting the clock if Python is the only application that's running. That's way too long for a min sleep to avoid a busy loop.</p>
<p>Does anybody know how I can get Windows to sleep less than that value?</p> | 2 |
TableView change all the rows when I try to edit one column value in javafx | <p>I have a <code>TableView</code> that has its items property bound to a class <code>Group</code>'s <code>applications</code> property which is declared as :</p>
<pre><code>ObjectProperty<ObservableList<Application>> applications = new SimpleObjectProperty();

<p>it is initialised as :</p>
<pre><code>applications.set(new FXCollections.observableArrayList<Application>());
applications.get().add(new Application());
applications.get().add(new Application());
</code></pre>
<p>The class <code>Application</code> class contains some properties and another class <code>Customer</code> declared and initialised as :</p>
<pre><code>ObjectProperty<Customer> customer = SimpleObjectProperty<>(new Customer());
</code></pre>
<p>Now there are four columns in the tableView that are editable they are 'ApplicationNo', 'ApplicationDate', 'CustomerId' and 'CustomerName'. The first 2 column's cell value factory is set to <code>Application</code> class's <code>applicationNo</code> and <code>applicationDate</code> properties. and the last 2 column's cell value factory are set to the <code>Application</code> class's <code>customer</code> property's <code>customerId</code> and <code>customerName</code> properties. All the four columns are editable with combobox control that are populated with values from the database.</p>
<p>In addition to the above stated table view, I have a form in the FXML consisting of fields that are there in the <code>Application</code> class and the <code>Customer</code> class. This form is disabled when no table row is selected and is enabled with the values of the <code>Application</code> instance, when any of the table view row is selected.</p>
<p>Now my problem is when I select any row and edit the values in the form or in the table, all the row attain the new value that I enter.</p>
<p>I am not uploading the code because it is very lengthy.</p>

<p>So it compiles, but when using the binding project in the Xamarin.Android project it takes several mins. to compile and then it fails complaining about the HEAP size of Java. </p>
<p>When I set the heap size to 1GB, it completes, but debugging is then broken when running the app in debug mode on device.</p>
<p>Is there a way to just use the ARRs without a binding library? I just need to invoke a wrapper method that I made in this ARR and get the output from that. I don't need to access the full library through C#. Or is there a better way?</p>
<p>Update:
And when I build the CPU looks like this (Look at Java):

Getting a Recursive Query to work in Access 2013 | <p>After a day's worth of research, I thought I was just at the finish line with my problem. I got myself all schooled up on recursive queries and managed to get it to execute beautifully in SQL Server Management Studio 2014. However, I was immediately shot down when translating the query I wrote in SQL Server 2014 into my Access 2013 application. Reading other articles, I now understand that Access does not support recursive queries. With that, I need help finding a resource-efficient way to pull these records and put them into an array variable. My past efforts in emulating this in VBA were horrific; resulting in 30-60 seconds to process. Any advise on how to lean this process out would be greatly appreciated.</p>
<p>The recursive query I would like to emulate is:</p>
<pre><code>WITH MyCTE(BusinessUnitID, Active)
AS(
SELECT a.BusinessUnitID, a.Active
FROM t_EMS_BM_BusinessUnits AS a
WHERE BusinessUnitID = 7
UNION ALL
SELECT d.BusinessUnitID, d.Active
FROM MyCTE AS c
INNER JOIN t_EMS_BM_BusinessUnits AS d
ON c.BusinessUnitID = d.ParentUnit)
SELECT *
FROM MyCTE
WHERE Active = 1
</code></pre>
<p>My atrocious VBA script is:</p>
<pre class="lang-vb prettyprint-override"><code>Private Sub LoadArray(intBU As Integer)
'set rollup data for business unit by adding all child units to intBUs array
Dim sql As String
Dim rs As Recordset
Dim intCount As Integer
sql = "SELECT BusinessUnitID, ParentUnit FROM t_EMS_BM_BusinessUnits WHERE Active = true ORDER BY BusinessUnitID"
Set rs = currentdb.OpenRecordset(sql, dbOpenDynaset, dbSeeChanges)
'look for child units
With rs
intCount = 0
ReDim intBUs(1 To 1) As Integer
If Not .EOF And Not .BOF Then
.MoveLast
.MoveFirst
Do While Not .EOF
If IsChild(intBU, !BusinessUnitID) = True Then
'add to array
intCount = intCount + 1
If intCount > 1 Then
ReDim Preserve intBUs(1 To UBound(intBUs) + 1) As Integer
intBUs(UBound(intBUs)) = !BusinessUnitID
ElseIf intCount = 1 Then
intBUs(UBound(intBUs)) = !BusinessUnitID
End If
End If
.MoveNext
Loop
End If
.Close
End With
Set rs = Nothing
Private Function IsChild(TargetBU, CurrentBU As Integer) As Boolean
'check if unit is lowest level child
'is TargetBU a child of CurrentBU?
Dim intX As Integer
Dim intCount As Integer
intX = 0
If TargetBU = CurrentBU Then
'return a value of true
IsChild = True
Else
Do Until intX = -1
'find bottom level of heiarchy
intCount = DCount("BusinessUnitID", "t_EMS_BM_BusinessUnits", "ParentUnit=" & CurrentBU)
If intCount = 0 Then
intX = -1
Else
CurrentBU = DLookup("BusinessUnitID", "t_EMS_BM_BusinessUnits", "ParentUnit=" & CurrentBU)
intX = 0
End If

'tree up until the record matches the TargetBU or reaches the top "0"

'move up to the next level

eventReactive two action buttons Shiny | <p>I'm trying to trigger different function on the same output with two action buttons.
<code>interests_data</code> and <code>interests_data_refresh</code> are eventReactive depending on two different output. </p>
<p>Isolate may not take more than one action button. I tried to keep track on the first input but I'm afraid refreshing the page may cause problem on the tracking. I haven't seen any example about how to do this problem ie having different behavior on the same output depending on the button pressed. Here is my attempt :</p>
<pre><code>output$mytable2 <- DT::renderDataTable({
input$insert
input$delete
isolate({
if (input$insert == 0) {
start_interests <- dbReadTable(db, "Interests")
DT::datatable(start_interests[],
options = list(
lengthMenu = c(10, 25, 50, 100, 150, 200),
order = list(list(7, 'desc')),
pageLength = 25
))
}
else if (input$insert == x+1) {
#updated_interests()
DT::datatable(interests_data(),
options = list(
lengthMenu = c(10, 25, 50, 100, 150, 200),
order = list(list(7, 'desc')),
pageLength = 25

How do I get a python script filename as title for a plot correctly shown from Jupyter? | <p>I like to use a python script to generate a figure. That figure should have the script filename (with full path) as part of the title. For example:</p>
<pre><code>import numpy as np
import matplotlib.pyplot as plt
plt.rcParams['text.usetex'] = True
x = np.linspace(0, 10, 10)
titleString = __file__.replace('_', '\_')
plt.plot(x, x)
plt.title(titleString)
plt.show()
</code></pre>
<p>The IPython console in Spyder shows the title correctly:</p>
<p><a href="https://i.stack.imgur.com/Vlfa5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Vlfa5.png" alt="enter image description here"></a></p>
<p>However, if I run the script (on Windows 7, using Anaconda with Jupyter Notebook 4.2.1 and Spyder 2.3.9) from within a Jupyter Notebook via</p>
<pre><code>%matplotlib inline
%run 'H:/Python/Playground/a_test'

<p><a href="https://i.stack.imgur.com/Qty0c.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Qty0c.png" alt="enter image description here"></a></p>
<p>Note that the scripts path and filename is not correct. Is there a way to fix this?</p> | 2 |
Consuming a WSDL/Web service in C#/VisualStudio 2015 | <p>While there are many other topics that provide great information on the topic posted here already, I've not yet been able to find the answer to my dilemma.</p>
<p>While I'm somewhat competent with PowerShell, I am completely new with C#/VisualStudio. I have some PowerShell code that consumes a Web service that works perfectly well:</p>
<pre><code>function Modify-SPMLObject() {
param(
[string]$Uri
, [string]$ObjectDN
, [PSCredential]$Creds
, [hashtable]$Attributes
)
$MyService = New-WebServiceProxy -Uri $Uri -Credential $Creds
$Type = $MyService.GetType().Namespace
$ModifyRequest = New-Object -TypeName ($Type + ".CModifyRequest")
$CPSOID = New-Object -TypeName ($Type + ".CPSOID")
$CPSOID.ID = $ObjectDN
$ModifyRequest.psoID = $CPSOID
$Modifications = @()
foreach ($Attribute in $Attributes.Keys) {
$Modification = New-Object -TypeName ($Type + ".modification")
$Modification.Name = $Attribute
$Modification.Value = $Attributes.$Attribute
$Modification.Operation = "replace"
$Modifications += $Modification
}
$ModifyRequest.modification = $Modifications
$MyService.modify($ModifyRequest)
}
</code></pre>
<p>My challenge is converting this to C# in VisualStudio. In lieu of the call to <em>New-WebServiceProxy</em>, I've included a reference in my project to the Web service. The reference is named <em>MyService</em>. Hence, the code I've created thus far:</p>
<pre><code>var ModifyRequest = new MyService.CModifyRequest();
var CPSOID = new MyService.CPSOID();
CPSOID.ID = "a hard-coded value for now";
ModifyRequest.psoID = CPSOID;
var modifications = new MyService.modification[1];
var modification = new MyService.modification();
modification.name = "another hard-coded value for the moment";
modification.operation = "replace";
modification.value = new string[1] { "This is a test" };
modifications[0] = modification;
ModifyRequest.modification = modifications;
</code></pre>
<p>The one thing that I haven't been able to figure out, however, is how, in C#, to accomplish the task that the PowerShell version accomplishes thus:</p>
<pre><code>$MyService.modify($ModifyRequest)
</code></pre>
<p>In VS, if I try to call:</p>
<pre><code>MyService.modify(ModifyRequest);
</code></pre>
<p>I get the message</p>
<blockquote>
<p>Error CS0234 The type or namespace name 'modify' does not exist in the namespace 'WebApplication2.MyService' (are you missing an assembly reference?)</p>
</blockquote>
<p>Any tips are most appreciated!</p>
<p>EDIT: Found the solution. In answer to LachlanB, typing "MyService" provided a list of methods and classes - but <strong>not</strong> the <em>modify</em> operation that I was seeking and defined in the WSDL thus:</p>

<p>What I needed to include was, first, the reference:</p>
<pre><code>using WebApplication2.MyService;
</code></pre>
<p>With that, I could then call:</p>
<pre><code>MyApplicationClassName webService = new MyApplicationClassName();
CModifyResponse response = webService.modify(ModifyRequest);
</code></pre>
<p>where "MyApplicationClassName" was automatically generated as was listed in References.cs in the following statement:</p>
<pre><code>public partial class MyApplicationClassName : System.Web.Services.Protocols.SoapHttpClientProtocol {

Maven resource folder | <p>Hy,
I want to get the resource folder (ex: C:\Users\Raul\workspace\Serial\src\test\resources) in a Maven project but every time I run this java code:</p>
<pre><code>System.out.println(getClass().getResource("").getPath());
</code></pre>
<p>it returns me this path: C:/Users/Raul/workspace/Serial/target/test-classes/</p>
<p>The last time I used Maven, worked that way without any changes from me.
Thx in advance.</p> | 2 |
Pop view controller using Screen edge pan gesture recogniser not following the thumb | <p>As soon as I've added custom bar navigation bar button item I've lost the ability to use the default function to go back. I'd like to have the ability to use "swipe from edge" to go back.</p>
<p>I've added the Edge Pan Gesture Recogniser and connected it to @IBAction, but the dismissing action happens completely as soon as the pan gesture is recognised.</p>
<p>Instead of slowly following my thumb (as seen in other apps), the current view moves out with predefined animation.</p>
<p>How to make the animation following my thumb using Edge Pan Gesture Recogniser?</p>
<pre><code>@IBAction func edgeSwipe(sender: AnyObject) {
navigationController?.popViewControllerAnimated(true)
}
</code></pre>

Azure Web App doesn't start node server | <p>I am publishing my typescript node.js/express azure app via bitbucket, and it appears that everything is compiling properly, however azure doesn't start the app.</p>
<p>A reproable repository is <a href="https://bitbucket.org/somkun/azureexample" rel="nofollow">here</a>. I tried cloning the app to a fresh local directory, then running the deploy.cmd and calling node start in the output folder, and that worked fine.</p> | 2 |
Should I use Cocoa Bindings in Swift? | <p>I am not too sure about the fundamental difference between Cocoa Bindings and IBOutlets/IBActions. I am currently migrating an Obj-C project to Swift 3 and I want to know whether it is common practice to use bindings, especially in Swift? There is very little community discussion on bindings in general and I am CS student new to Cocoa/CocoaTouch dev, so I would appreciate verbose answers.</p> | 2 |
Remotely deactivate an excel file via vba | <p>I would like to know if there is a way to remotely deactivate an excel file via vba.</p>
<p>The problem:<br>
My company uses an excel file for sales to provide quotations to the customer. Now when there is an update to our pricing scheme I send a new version of the Excel file to the sales team. The obvious thing that happens next is that they don't use the most current version of the file to give a quote => the customer gets a wrong price.</p>
<p>What I tried so far:<br>
I implemented a time bomb that lets the file expire at a defined date. The problem with this is that updates to the excel file happen irregularly.</p>
<p>What I have in mind:<br>
Once the excel file starts a VBA script queries a web server for the most current version number. If the version number in the currently opening Excel file is lower than the one provided by the server, the file locks up.</p>
<p>Is this something one can realize with Excel and VBA? I could imagine that this causes some problem with Windows Security etc. because it may look like a trojan or virus.</p>
<p>You help is much appreciated!</p> | 2 |
