Scala java.nio.charset.UnmappableCharacterException: Input length = 1 | <p>I've found several questions with similar titles, but couldn't seem to use any to resolve my issue. I Can't seem to load my .csv file:</p>
<pre><code>val source = io.Source.fromFile("C:/mon_usatotaldat.csv")
</code></pre>
<p>Returns:</p>
<blockquote>
<p>java.nio.charset.UnmappableCharacterException: Input length = 1</p>
</blockquote>
<p>So I tried:</p>
<pre><code>val source = io.Source.fromFile("UTF-8", "C:/mon_usatotaldat.csv")
</code></pre>
<p>and got:</p>
<blockquote>
<p>java.nio.charset.IllegalCharsetNameException: C:/mon_usatotaldat.csv</p>
</blockquote>
<p>I guess UTF-8 wouldn't work, if the file isn't in UTF-8 format, so that makes sense, but I don't know what to do next.</p>
<p>I've managed to discover the encoding is windows-1252 using:</p>
<pre><code>val source = io.Source.fromFile("C:/mon_usatotaldat.csv").codec.decodingReplaceWith("UTF-8")
</code></pre>
<p>But this didn't do what I had expected, which was convert the file to UTF-8. I have no Idea how to work with it.</p>
<p>Another thing I've tried was:</p>
<pre><code>val source = io.Source.fromFile("windows-1252","C:/mon_usatotaldat.csv")
</code></pre>
<p>But that returned:</p>
<blockquote>
<p>java.nio.charset.IllegalCharsetNameException: C:/mon_usatotaldat.csv</p>
</blockquote>
<p>Please help. Thanks in advance.</p> | 1 |
Drawing on a panel by clicking a button in WinForms | <p>I'm trying to make a program to draw on the a <code>Panel</code> (a square, circle, etc...) by clicking on a button.</p>
<p>I have not done much so far, just tried the code drawing directly to the panel but don't know how to move it to the button. Here is the code I have so far.</p>
<p>If you know a better method to draw than the one I'm using please let me know.</p>
<pre><code>public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void mainPanel_Paint(object sender, PaintEventArgs e)
{

g = CreateGraphics();
Pen pen = new Pen(Color.Black);
Rectangle r = new Rectangle(10, 10, 100, 100);
g.DrawRectangle(pen, r);
}

How to extract a Google link's href from search results with Selenium? | <p>Ultimately I am just trying to get the href of the first link to google's search result</p>
<p>The information I need also exists in an 'a' element, but it is stored in a 'data-href' attribute, which I could not figure how to extract the data from (<code>get_attribute('data-href')</code> returns <code>None</code>).</p>
<p>I am using Phantomjs, but have also tried with Firefox web driver</p>
<hr>
<p>The href is displayed in a <code>cite</code> tag in a google search (which can be found by inspecting the small green link text under each link in google search results). </p>
<p>The cite element is apparently found with Selenium, but the text returned (<code>element.text</code>, or <code>get_attribute('innerHTML')</code>, or (<code>text</code>)) is not what is shown in the html.</p>
<p>For instance, there is a cite tag <code><cite class="_Rm">www.fcv.org.br/</cite></code>, but <code>element.text</code> shows “wikimapia.org/.../Fundação-Cristiano-Varella-Hospital...”</p>
<p>I have tried to retrieve the cite element with <code>by_css_selector</code>, <code>tag_name</code>, <code>class_name</code>, and xpath with the same results.</p>
<pre><code>links = driver.find_elements_by_css_selector('div.g') # div[class="g"]
link = links[0] # I am looking for the first link in the main links section
next = link.find_element_by_css_selector('div[class="s"]') # location of cite tag
nextB = next.find_element_by_tag_name('cite')
</code></pre>
<p>div containing cite tag (there is only one in the div)</p>
<pre><code> <div class="s">
<div>
<div class="f kv _SWb" style="white-space:nowrap">
<cite class="_Rm">www.fcv.org.br/</cite>

How is it possible to get "ActiveRecord::DuplicateMigrationNameError" with only 1 migration file? | <p>Here is the setup. Have a Ruby off Rails API application setup. </p>
<p>It pulls in a "database creation application" independently via git submodule. There is a "db/migrate" folder with one migration file and a "db/structure.sql" file. The database creation project is essentially a slimmed down Rails project - we used Rails because we needed rake tasks to let us easily migrate.</p>
<p>The structure.sql file essentially recreates our old database schema (we decided to keep the database code in a separate repo due to having multiple apps that need to access the database and a desire to keep the database consistent as possible).</p>
<p>If I do <code>rake db:create</code> I get told that <code>app_development</code> and <code>app_test</code> exist. I've manually deleted the schema_migrations and schema_info tables from both. In fact app_test, is empty and contains no tables.</p>
<p>If I run rake db:migrate, I get told:</p>
<pre><code>ActiveRecord::DuplicateMigrationNameError:
Multiple migrations have the name YourMigrationToTableBlahBlah
</code></pre>
<p>How is this possible and how do I work around this error so I can migrate?</p>
<p>At one point I did do a git commit that renamed the columns in the 1 migration file in db/migration, but I deleted the tables in app_development and app_test as well as the schema_migrations table so the Rails rake task should not be complaining about this.</p>
<p>EDIT:</p>
<p>One thing I noticed is that during the running of <code>bundle exec rake db:migrate</code> is that the same migrations folder path (e.g., "db/migrate") is being added to <code>ActiveRecord::Tasks::DatabaseTasks.migrations_paths</code> but I don't know why </p> | 1 |
OpenOffice / LibreOffice Base SQL Group By | <p>I have a small LibreOffice database with customer data and invoices. Each invoice consists of n items.</p>
<p>Customers:</p>
<pre><code>**********************
* ID * Name * Adress *
**********************
* 0 * N1 * A1 *
* 1 * N2 * A2 *
**********************
</code></pre>
<p>Invoices:</p>
<pre><code>********************************
* ID * CustomerID * Date *
********************************
* 0 * 0 * 01/01/1970 *
* 1 * 0 * 08/02/1971 *
********************************
</code></pre>
<p>Items:</p>
<pre><code>***********************************
* ID * InvoiceID * Amount * Price *
***********************************
* 1 * 0 * 12 * 12.95 *
* 2 * 0 * 9 * 8.75 *
* 3 * 1 * 29 * 8.75 *
***********************************
</code></pre>
<p>I want to create a query with the value of an invoice:</p>
<pre><code>SELECT "invoices"."ID", SUM( "items"."Amount" * "items"."Price" )
FROM "invoices", "items"
WHERE "invoices"."ID" = "items"."InvoiceID"
GROUP BY "invoice"."ID"
</code></pre>
<p>So far everything works. But if I want to include some more information to the query, e.g. </p>
<pre><code>SELECT "invoices"."ID", "invoices"."Date", SUM( "items"."Amount" * "items"."Price" )
FROM "invoices", "items"
WHERE "invoices"."ID" = "items"."InvoiceID"
GROUP BY "invoice"."ID"
</code></pre>
<p>I get the error message <code>Not in aggregate function or group by clause</code>. I tried it in phpmyadmin and it worked, so I think, that the SQL Syntax should be ok. What is the problem with my SQL statement?</p> | 1 |
Listview Checkbox - vb.net | <p>Ok, i have a listview with checkboxes and a button, how it works is that i have to check the items i want to change the values, then press the button to change the value of those checked item, here's my code on the button.</p>
<pre><code> Try
Dim I As Integer
If lv_id.CheckedItems.Count = 0 Then
For I = 0 To lv_id.Items.Count - 1
lv_id.Items(I).SubItems(1).Text = "Pending"
Next
Else
For I = 0 To lv_id.CheckedItems.Count - 1
lv_id.CheckedItems(I).SubItems(1).Text = "Submitted"
Next
End If
Proc_Items.BackColor = Color.Green
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
</code></pre>
<p>Now, what i want to do is, to remove the button and then when i'll check the item i want to the code above will do the process without pressing the button, i tried "ItemCheck, ItemChecked" event, but with no luck.</p> | 1 |
Sweet Alerts is display UTF-8 Chars wrong | <p>I don't know what is wrong, I have this JavaScript function:</p>
<pre><code><script charset="utf-8" type="text/javascript">
$(document).ready(function(){
//initialize the javascript
App.init();
@if(Session::has('message'))
var msg = '{{ Session::get('message') }}';
console.log(msg);
swal({
title: "",
text: 'compa&ntilde;ia',
type: "warning",
confirmButtonText: "Ok!",
closeOnConfirm: false
});
$(window).bind("load", function() {
$.gritter.add({
title: 'Atencion',
text: 'compa&ntilde;ia',
image: '{{ asset('images/clipboard_icon.png') }}',
class_name: 'danger',
time: ''
});
return false;
});
@endif
});
</script>
</code></pre>
<p>The problem is that sweet alerts doesn't display: <code>'compañia'</code> it displays <code>'compa&ntilde;ia'</code> but the gritter message is correctly displaying the word. (See picture)
<a href="https://i.stack.imgur.com/7neBA.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7neBA.png" alt="enter image description here"></a></p>
<p>As you can see the red gritter correctly displays the word, but the sweet alert doesn't,</p>
<p>The file is UTF-8 encoded, so is the meta and the script also just in case, and before you ask why I put <code>'compa&ntilde;ia'</code> its part of a larger message that is send by Laravel on the session and retrieved by the view in that format.</p>
<p>Anyway my real question is why does the gritted display the word fine and how can I fix it so it works also on sweet alert.</p> | 1 |
How do I query RealmObject that have RealmList that contains specified value | <p>I have a <code>RealmObject</code> (let's say <code>Owner</code>) and it has <code>RealmList<Cat></code>. <code>Cat</code> has a property <code>name</code>. How do I query for all the <code>Owner</code>s who have cat with specified name ?</p>
<p>I tried:</p>
<pre><code>RealmResult<Owner> owners = realm.query(Owner.class)
.contains("cats", "Garfield")
.findAll();
</code></pre>
<p>But it does not work.</p>

"Required module not found" for module that exists in node_modules | <p>Some modules just seem to be invisible to Flow. For example I have <a href="https://www.npmjs.com/package/react-native-overlay" rel="nofollow">react-native-overlay</a> installed via npm into my node_modules directory but I get a whole bunch of errors like this from Flow:</p>
<pre><code>[js/components/DatePickerOverlay.js:18
18: let Overlay = require('react-native-overlay');
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ react-native-overlay. Required module not found
</code></pre>
<p>This module doesn't have types so it would be fine if I could just get Flow to ignore it entirely.</p>
<p>Here's my .flowconfig (based on React Native's one):</p>
<p><a href="https://gist.github.com/almost/20c6caf6d18d0e5c689f" rel="nofollow">https://gist.github.com/almost/20c6caf6d18d0e5c689f</a></p>
<p>As you can see I'm on flow 0.20.1 and I have module.system=haste (as required by React Native)</p>
<p>I tried adding a //$FlowIgnore comment to the import lines but then Flow complains about an unneeded ignore comment! I also tried creating a react-native-flow.js.flow file with a dummy export which seemed to work at first but then after a flow restart stopped working.</p>
<p>Any ideas for how to either help Flow find this module or make it ignore the import line completely?</p> | 1 |
Laravel 5 missing required parameters on destroy route | <p>I recently upgraded from laravel 5.1 to 5.2 and now I'm getting an error of <code>Missing required parameters for [Route: example.destroy] [URI: example/{args}]</code>.</p>
<p>The error occurs here:
<code><form class="form-horizontal" action="<?php echo route('example.destroy'); ?>" method="post"></code> on the action attribute of the form.</p>
<p>Here's how the route was registered on the <code>route.php</code></p>
<pre><code>Route::resource('example', 'ExampleController');
</code></pre>
<p>When I was in 5.1, there was no error with this line. Just went I upgrade to 5.2, it now occurs.</p>
<p>The functionality of this is that it will allow user to delete multiple entries by checking the checkboxes that they wish to be deleted. Then upon submit, it will redirect to the destroy method on the controller.</p> | 1 |

Subquery in Yii2 order by and group by | <p>In mysql the query command I am using is this:</p>
<pre><code>SELECT * FROM (SELECT * FROM `storefirmware_updates` ORDER BY
`old_version` DESC) AS tmp_table GROUP BY store_id

<pre><code> $subquery = new Query;
$subquery->select(["*"]);
$subquery->from('storelist_update_view')->orderBy('old_version DESC');
$query = new Query;
$query->select(["*"]);
$query->from('storelist_update_view')->groupBy(['store_id' => $subquery]);

Can I expose Swift default parameter values to Objective-C? | <p>Say I have some Swift class with methods I'd like to expose to Objective-C:</p>
<pre><code>@objc(Worker) class Worker : NSObject {
func performWork(label: String = "Regular Work") {
// Perform work
}
}
</code></pre>
<p>I can call this in two ways:</p>
<pre><code>Worker().performWork()
Worker().performWork("Swift Development")
</code></pre>
<p>However, when called from Objective-C, I do not get the "default" version of this method - I <em>must</em> supply a label:</p>
<pre><code>[[[Worker alloc] init] performWork:@"Obj-C Development"];
</code></pre>
<p>See the definition from my <code>AppName-Swift.h</code> header below:</p>
<pre><code>SWIFT_CLASS_NAMED("Worker")
@interface Worker : NSObject
- (void)performWork:(NSString * __nonnull)label;
- (nonnull instancetype)init OBJC_DESIGNATED_INITIALIZER;
@end
</code></pre>
<p>I would <em>expect</em> to see a method with this signature:</p>
<pre><code>- (void)performWork;
</code></pre>
<p>I realise ObjC doesn't support default parameter values, but my assumption was that the Swift default values simply generate additional Swift functions with trivial implementations calling the "real" function (i.e. they're syntactic sugar hiding the <a href="https://stackoverflow.com/a/561207/1217087">typical implementation</a> we'd use in Obj-C).</p>
<p>Is there any way to expose this default value to Objective-C? If not, can anyone point me to any documentation on why this isn't available?</p> | 1 |

Eclipse comment auto-generation | <p>For a programming course, I'm required to put comments within each class and method describing the following five things: <strong>Methods</strong>, <strong>fields</strong>, <strong>methods on fields</strong>, <strong>parameters</strong>, and <strong>methods on parameters</strong>. The first three are to be put directly under the class heading, and the last two are specific to each method. </p>
<p>Below is an example of what these comments should look like.</p>

* Methods:
* - String convertToString();
* - String formatString();
* Fields:
* - String first;
* - ILoString rest
* Methods on fields:
* - All String methods
* - All ILoString methods

String first;
ILoString rest;

<p>Naturally, it is tedious and redundant to type all these out for every single class and method in a large file. Is there a way to generate these automatically, in Eclipse or otherwise?</p>

Why python numpy.delete does not raise indexError when out-of-bounds index is in np array | <p>When using np.delete an indexError is raise when an out-of-bounds index is used.

How to aggregate multiple XMLELEMENT using XMLAGG | <p>I want to aggregate multiple XMLELEMENT for table following columns and return an xml file.</p>
<p>Here is the table data:
<a href="https://i.stack.imgur.com/eO4f1.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/eO4f1.png" alt="enter image description here"></a></p>
<p>I want return xml with following format:</p>
<pre><code><employee>
<id>FMCSC00015</id>
<year>2016</year>
<month>1</month>
<head_name>BASIC PAY</head_name>
<amount>35600</amount>
<head_name>BANK LOAN-4</head_name>
<amount>23490</amount>
<head_name>RESEARCH ALLOWANCE</head_name>
<amount>1500</amount>
<head_name>MOTOR GARAGE</head_name>
<amount>500.5</amount>
<head_name>CLUB</head_name>
<amount>207</amount>
.........so on
<employee>
</code></pre>
<p>But i am facing difficulty on aggregating 2 columns [head_name and amount].
here is my oracle code:</p>
<pre><code> select xmlElement( "employee",
xmlelement("id", e.PAYMSTR_EMPID),
xmlelement("year", e.PAYMSTR_SALYR),
xmlelement("month", e.PAYMSTR_SALMT),
XMLAGG(
XMLELEMENT(" ",
XMLELEMENT("head_name", e.PAYMSTR_SALHDNM ),
XMLELEMENT("amount", e.PAYMSTR_AMOUNT ) )
)
) as result
from TBL_PAYROLL_MASTER_FILE e
where e.PAYMSTR_EMPID = 'FMCSC00015'
group by e.PAYMSTR_EMPID,e.PAYMSTR_SALYR, e.PAYMSTR_SALMT;
</code></pre>
<p>As you can see because i used white space inside the first XMLELEMENT of XMLAGG, it still creates <strong>empty tags</strong> with following output xml:</p>
<pre><code><employee>
<id>FMCSC00015</id>
<year>2016</year>
<month>1</month>
<>
<head_name>BASIC PAY</head_name>

<head_name>BANK LOAN-4</head_name>
<amount>23490</amount>
</>
<>
<head_name>RESEARCH ALLOWANCE</head_name>
<amount>1500</amount>
</>
<>
<head_name>MOTOR GARAGE</head_name>
<amount>500.5</amount>
</>
<>
<head_name>CLUB</head_name>
<amount>207</amount>
.........so on
<employee>
</code></pre>
<p>How can i avoid this extra empty tags and get my appropriate xml format.Thanks</p> | 1 |

Execute http request in parallel with Retrofit 2 | <p>I want to implement multiple parallel request in Retrofit 2.
I have the following structure to make 3 request :</p>
<pre><code>HistoricalRApi.IStockChart service=HistoricalRApi.getMyApiService();
//^BVSP,^DJI,^IXIC
Call<HistoricalDataResponseTimestamp> call1= service.get1DHistoricalDataByStock("^IXIC");
Call<HistoricalDataResponseTimestamp> call2= service.get1DHistoricalDataByStock("^DJI");
Call<HistoricalDataResponseTimestamp> call3= service.get1DHistoricalDataByStock("^GSPC");
call1.enqueue(retrofitCallbackAmerica());
call2.enqueue(retrofitCallbackAmerica());
call3.enqueue(retrofitCallbackAmerica());
}
</code></pre>
<p>I have read that in Retrofit1, when defining the rest adapter one can define parallel request with .setExecutor like here: </p>
<pre><code>RestAdapter adapter = new RestAdapter.Builder()
.setEndpoint(END_POINT)
.setLogLevel(RestAdapter.LogLevel.FULL)
.setExecutors(Executors.newFixedThreadPool(3), null)
.build();
</code></pre>
<p>My question is how can i achieve the same in Retrofit 2? Thanks in advance</p> | 1 |

Binding an event to a method, why does it work in UWP? | <p><code>UWP</code> came with a new way of <code>DataBinding</code>, <code>Compiled Binding</code>, using the <code>{x:Bind}</code> markup extension, when I was discovering this new feature, I found out that we can actually bind an event to a method !</p>
<p><strong>Example :</strong></p>
<p><strong>Xaml :</strong></p>
<pre><code><Grid>
<Button Click="{x:Bind Run}" Content="{x:Bind ButtonText}"></Button>
</Grid>
</code></pre>
<p><strong>Code Behind :</strong></p>
<pre><code>private string _buttonText;
public string ButtonText
{
get { return _buttonText; }
set
{
_buttonText = value;
OnPropertyChanged();
}
}
public MainPage()
{
this.InitializeComponent();
ButtonText = "Click !";
}
public async void Run()
{
await new MessageDialog("Yeah the binding worked !!").ShowAsync();
}
</code></pre>
<p><strong>The result :</strong></p>
<p><a href="https://i.stack.imgur.com/6v3UQ.png" rel="noreferrer"><img src="https://i.stack.imgur.com/6v3UQ.png" alt="enter image description here"></a></p>
<p>And since {x:Bind} bindings are evaluated at runtime and the compiler generates some files that represent that binding, so I went there to investigate what's going on, so in the MainPage.g.cs file (MainPage is the xaml file in question) I found this :</p>
<pre><code> // IComponentConnector
public void Connect(int connectionId, global::System.Object target)
{
switch(connectionId)
{
case 2:
this.obj2 = (global::Windows.UI.Xaml.Controls.Button)target;
((global::Windows.UI.Xaml.Controls.Button)target).Click += (global::System.Object param0, global::Windows.UI.Xaml.RoutedEventArgs param1) =>
{
this.dataRoot.Run();
};
break;
default:
break;
}
}
</code></pre>
<p>The compiler seems to know that it's a valid binding, moreover it creates the corresponding event handler, and it calls the concerned method inside.</p>
<p>That is great ! but why ?? A binding target should be a dependency property, not an event. <a href="https://msdn.microsoft.com/en-us/library/windows/apps/mt204783.aspx" rel="noreferrer">The official documentation for {x:Bind}</a> does mention this new feature, but doesn't explain why and how can a non dependency property be a target of binding, anyone who has a deep explanation for this ?</p> | 1 |

MySQL Error 1055 information_schema.PROFILING.SEQ on every query | <p>I'm using a recent install of mysql from the mysql repository, installed on Ubuntu 14.04. Every query I run results in the error below and I have been unable to find anything that discusses this via google or here.</p>
<p>For example, this (obviously for demonstration purposes only) query returns the following:</p>
<hr>
<p>[SQL]SELECT *
FROM
tabcLocations</p>
<p>Affected rows: 0
Time: 0.705s</p>
<h2>[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'information_schema.PROFILING.SEQ' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by</h2>
<p>It returns the results of the query just fine, but throws an error on every query, which will obviously affect error handling in my applications. Any suggestions on how to resolve this? It's fairly maddening at the moment.</p> | 1 |

How to navigate to the corresponding java class from XML layout for fragments in Android Studio? | <p>Suppose that I am in a layout file named "main.xml" and its corresponding fragment java class is "MainFragment.java".</p>
<p>Is there any shortcut to go to "MainFragment.java" from the "main.xml" or any other way?</p>
<p>It will be helpful to navigate around xml and java classes quickly when there are a lot of java classes and xml files in the project.</p>
<p><strong>Note:</strong> For activity, there is a “C” symbol found in the top-left corner of the layout XML file. When we click that "C" symbol it will take us to corresponding java class in which the xml file is used. But for fragments, there is nothing available.</p> | 1 |

IPython (Jupyter) notebook producing ghost line in all equations | <p>I installed IPython / Jupyter using pip on a new machine (Macbook Air with El Capitan). In a fairly simple notebook of mine (created with the same version of the whole stack) all equations, inline or not, suddenly have a vertical line on the right hand side; same height as the embedded image. </p>
<p>This is the case even for a single inline symbol such as <code>$x$</code>. I have no complicated macros or any weird LaTeX hacking going on.</p>

ProcessQueueMessage function in WebJob console app | <p>I'm creating a new console app that I will run as a WebJob on Azure. When I created the new app in Visual Studio, it already created a Function.cs class that contains the following method which automatically picks up the message from my queue and processes it.</p>
<pre><code>public static void ProcessQueueMessage([QueueTrigger("queue")] string message, TextWriter log)
{
log.WriteLine(message);
}
</code></pre>
<p>My question is how do I have a bit more control over handling the queue message. For example, I 'd like to make sure the message is processed and deleted. This method seems to do all of that for me but how do I know if the message is processed correctly? What if it fails, how do I tell it not to delete the message?</p> | 1 |
My Output has some weird symbols displaying | <p>I had to a coding for my class. The coding is about asking the user to type their Name, age and id. An then the program should for a passcode based on the first 6 letter in their name, their age and the first two letter in their student id. The problem is the a unidentified symbol (╠╠╠╠╠╠╠╠╠╠╠╠╠╠ )in the output. Can anyone tell me why it is there>? Then it should calculate and display the lenght of the passcode. Here is the code:</p>
<pre><code>#include <stdio.h>
#include <string.h>
void main(void)
{
char name[20], id[9], age[3], passcode[10];
int x;
puts("Enter your name:\n");
gets(name);
puts("\nEnter your student id:\n");
gets(id);
puts("\nEnter your age:\n");
gets(age);
x = strlen(passcode);
strncpy(passcode, name, 6);
strncat(passcode, id, 2);
printf("The passcode is:%s \n",passcode);
printf("The passcode has %d characters..\n",x);
}
</code></pre>
<p>And it look like:</p>
<pre><code>Enter your name:
johnny
Enter your student id:
dc87671
Enter your age:

The passcode is:johnny╠╠╠╠╠╠╠╠╠╠╠╠╠╠20dc
The passcode has 22 characters..

How can I let a div fill 100% width if no other elements are beside it? | <p>I have simple markup like this (a tab menu):</p>
<pre class="lang-html prettyprint-override"><code><div class="container">
<div class="tab1"></div>
<div class="tab2"></div>
<div class="tab3"></div>
</div>
</code></pre>
<p>That is the case when all elements have an equal width of 33% to fill 100% of the container.</p>
<p>Is it possible to apply a general CSS rule for all containers that automatically detects if, for example, there are only 1 other container or none? And then adjusts the width of the tabs? ("Strech-To-Fit")</p>
<p>Perhaps something with <code>min-width</code> or <code>max-width</code>? </p> | 1 |

how to find all employees under each manager | <p>I need to get a query to display the subordinates all the way down starting from one specific manager. Let's say I have this structure and I need to get all employees starting from ManagerId = 1 </p>
<pre><code>EmployeeId ManagerId
2 1
3 1
4 3
5 3
6 4
</code></pre>
<p><a href="https://i.stack.imgur.com/P2XQ7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/P2XQ7.png" alt="Here I have the visualization"></a></p>
<p>I need to get as result of the query the ManagerId and direct report employees under him, along with their subordinates.</p>
<p>For example, using SQL Server 2014:</p>
<pre><code>CREATE TABLE #Pepe (EmployeeId INT, ManagerId int)
INSERT INTO [#Pepe] ( [EmployeeId], [ManagerId] ) VALUES (2, 1)
INSERT INTO [#Pepe] ( [EmployeeId], [ManagerId] ) VALUES (3, 1)
INSERT INTO [#Pepe] ( [EmployeeId], [ManagerId] ) VALUES (4, 3)
INSERT INTO [#Pepe] ( [EmployeeId], [ManagerId] ) VALUES (5, 3)
INSERT INTO [#Pepe] ( [EmployeeId], [ManagerId] ) VALUES (6, 4)
</code></pre>
<p>Now I get the CTE</p>
<pre><code>;WITH relation AS
(
SELECT 1 as EmployeeId, 0 AS LEVEL
UNION ALL
SELECT r.EmployeeId, LEVEL + 1 AS LEVEL
FROM (SELECT EmployeeId, ManagerId FROM #Pepe) r
INNER JOIN relation T
ON r.ManagerId = T.EmployeeId
WHERE r.ManagerId <> r.EmployeeId
)
SELECT DISTINCT EmployeeId, LEVEL FROM relation
</code></pre>
<p>The result of my CTE is this:</p>
<pre><code>EmployeeId LEVEL
1 0
2 1
3 1
4 2
5 2
6 3
</code></pre>
<p>This result start from one specific employee which is 1 (is hardcoded on the CTE), now I need only the direct report, Level = 1 and also Level 0 too which are employee id 1, 2 and 3. </p>
<p>This is fine, now what I need is for each employee id (level 0 and 1), I need to get this result:</p>
<pre><code>EmployeeId ManagerId
1 1
2 1
3 1
4 1
5 1
6 1
2 2
3 3
4 3
5 3
6 3
</code></pre>
<p>As you can see the Manager Id contains the employees with level 0 and 1, and for each one I basically call the CTE to get all employees down, like for example ManagerId = 2 doesn't have subordinates but I need to count it anyway. Is there an efficient way to do this? I was using cross apply putting the CTE in an inline function but I was having troubles with performance.</p> | 1 |
Selecting User Control for Data Template based on an Enum | <p>I am working on a WPF app and currently I have an <code>ItemsControl</code> bound up to my View Model <code>ObservableCollection</code> and I have a <code>DataTemplate</code> that uses a <code>UserControl</code> to render the items on <code>canvas</code>. Can you use multiple User Controls and then switch which one is used based on an <code>Enum</code>? Another way to look it is to either create a <code>Button</code> or a <code>TextBox</code> for the item in the <code>ObservableCollection</code> based on an <code>Enum</code>. </p> | 1 |
Why does click for toggle checkbox become a double click? | <p>I am currently making a <code>checkbox</code> with a <code>label</code> attached to it. I use the <code>for</code> attribute to link the click for the checkbox.</p>
<p>I also have a jQuery function which <code>onclick</code> for the checkbox and labels container does a slide toggle for a text input field.</p>
<p>When I click the checkbox, only one click is detected and the text field slides down nicely. However, when I click the label it seems that a double click is happening so the text field slides down and then immediately back up.</p>
<p>I have an ID of <code>toggle-checkbox</code> on my checkbox and a <code>for="toggle-checkbox"</code> on my label and I suspect that somehow triggers an extra click.</p>
<p>HTML:</p>
<pre><code><div class="cart-summary__coupon-code">
<div class="form-group js-coupon-code">
<input class="cart-summary__coupon-code__checkbox" type="checkbox" id="toggle-checkbox">
<label class="cart-summary__coupon-code__label form-group__label--block" for="toggle-checkbox">click me</label>
</div>

<div class="coupon-code">

How to get a program to repeat itself using a while loop and if statement? | <p>I'm really new to Python and I'm finding it really hard to understand certain aspects of the language. I've been asked to create a program for an assignment and after hours of trying to use this website, I've come to no avail.</p>
<p>The question is:
Write a program which uses a loop to take in the first name, last name and
telephone number from an undefined number of users. The program
should allow the user the option to quit, after each iteration of the loop. <strong>The program should also write the information entered by the user to a text file called names.tx</strong></p>
<p>I have no problem with the part of the question in bold but I really can't wrap my head around the first bit. Here's what I have so far:</p>
<pre><code>def main():
infoList = []
count = 0
while True:
firstname = input('Please enter your first name: ')
lastname = input('Please enter your last name: ')
telephoneno = input('Please enter your telephone number: ')
contiinue = input('Continue (y = yes): ')
if contiinue == y:
count = count + 1
main()
</code></pre>
<p>When the program is iterating itself again, I want the user to be able to give different details to the questions. I know people hate when people ask questions and it seems like they're just trying to get people to do homework for them, but this will genuinely bug me for a while if I am unable to find a resolution.</p> | 1 |
Reading JSON file in Python and detecting specific keywords in field | <p>I just started this week to learn Python and I have the following question. I have a JSON file (Aberdeen2015.json) that contains 60 lines (each line containing a newspaper article). Moreover, each line contains a list with the <code>date</code>, <code>title</code> and <code>body</code> of the article (see picture below, title cannot be seen since it's towards the end of the line). </p>
<p><a href="https://i.stack.imgur.com/q0p2x.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/q0p2x.png" alt="enter image description here"></a></p>
<p>I want to do the following: if certain keywords are in the <code>body</code> of an article, print a list with the <code>date</code> of those articles. So far I have tried to do the following:</p>
<pre><code>with open("Aberdeen2015.json") as f:
for i in line():
if (' tax ' in body[i]
or ' Tax ' in body[i]
or ' policy ' in body[i]
or ' Policy ' in body[i]
or ' regulation ' in body[i]
or ' Regulation ' in body[i]
or ' spending ' in body[i]
or ' Spending ' in body[i]
or ' budget ' in body[i]
or ' Budget ' in body[i]
or ' central bank ' in body[i]
or ' Central Bank ' in body[i]
or ' Central bank ' in body[i]):
print("date")

Cannot convert a viewController object to viewController type in Swift | <p>I want to pass data from one view controller to another. And I am using the following code in the <code>prepareForSegue</code> to do so...</p>
<pre><code>let detailVC: DetailVC = segue.destinationViewController as! DetailVC
detailVC.alertDict = sender as! NSDictionary
</code></pre>
<p>In the first line as you can see there is a <code>!</code> after the as. Thats because I have to use it to <strong>force downcast</strong>, and if I do not include the <code>!</code> then I get an error: <code>UIViewController</code> is not convertable to <code>DetailVC</code>. But <code>DetailVC</code> is a inheritance of <code>UIViewController</code> class, so why can it not convert? Here is the code for the class..</p>
<pre><code>class DetailVC: UIViewController, MFMailComposeViewControllerDelegate, MFMessageComposeViewControllerDelegate {/*code*/}

Krajee Bootstrap fileinput how can i change the uploadExtraData dynamically | <p>Hi Am using Krajee Bootstrap fileinput , i need to change the <code>uploadExtraData</code> dynamically on submitting the form.

Change Connection String at Runtime in EF 6 | <p>I mostly use my dbcontext with using statements like this:</p>
<pre><code>using (var context = new MyContext())
{
}
</code></pre>
<p>But I later had to add a project with a function to change the database. I found out that I could change my dbcontext constructor to this:</p>
<pre><code>public MyContext(string connectionstring)
: base(connectionstring)
{
}
</code></pre>
<p>I made a class with a property for the connectionstring:</p>
<pre><code>public static class DbAccessor
{
public static string ConnectionStringForContext { get; set; }
}
</code></pre>
<p>I set this property in the beginning and my using statements look like this:</p>
<pre><code>using (var context = new MyContext(DbAccessor.ConnectionStringForContext)
{}
</code></pre>
<p>It works, but my connection string is now everywhere and I feel like I should not do that with connection strings. Is there a better way of doing this? What would be the best way to handle my Connection Strings if I want to change them? Should I stop using these using statements?</p>
<p>I've seen this question: <a href="https://stackoverflow.com/questions/20216147/entity-framework-change-connection-at-runtime">Entity Framework change connection at runtime</a></p>
<p>But the difference is, that I have a functioning solution, but I don't want to have my connection string everywhere. If I used that extension method inside every using statement. It would almost be like my solution just one line more in every using statement...</p> | 1 |

Ipython Notebook shows Import Error for Seaborn even when package is installed in Conda environment | <p>So I am trying to use Ipython notebook with Anaconda (Windows10). I got into anaconda cmd and create a new environment TryThis. I install Seaborn in this environment. And then I run Ipython command in the conda cmd.</p>
<pre><code> conda create --name TryThis python=2
activate TryThis
conda install seaborn
ipython
</code></pre>
<p>When I run </p>
<pre><code> import seaborn as sns
</code></pre>
<p>in this it executes allright.</p>
<p>However if I exit this and then run</p>
<pre><code> ipython notebook
</code></pre>
<p>in the conda cmd and go on to do the import in an ipython notebook in browser, it throws error</p>
<pre><code>---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-1-ed9806ce3570> in <module>()
----> 1 import seaborn as sns
ImportError: No module named seaborn

<p>I do not understand what is going wrong. If Seaborn is in this anaconda environment and I initiated Ipython notebook in this environment and Ipython in console can recognize it, why doesn't the notebook ?</p>
<p>What I might be doing is something blatantly incorrect, but I just started out with using anaconda !</p> | 1 |
Avoiding "An INSERT EXEC statement cannot be nested" | <p>I know that this is not possible to nest <code>insert ... exec</code> statements, but still I'm interested - is there a way to check if I already have active <code>insert ... exec</code> to avoid actual error?</p>

<pre><code>....
if <check if I have outer insert into exec> = 0
insert into <#some temporary table>
exec <stored procedure>
</code></pre>
<p>In other words - <code>insert ... exec</code> is optional, it's nice to have it, but I want to skip it if somebody tries to call my procedure with outer <code>insert ... exec</code></p> | 1 |

Connecting from psycopg2 on local machine to PostgreSQL db on Docker | <p>I have used the following commands to create a Docker image with Postgres running on it: </p>
<p><code>docker pull postgres
docker run --name test-db -e POSTGRES_PASSWORD=my_secret_password -d postgres</code></p>
<p>I then created a table called test and inserted some random data into a couple of rows.
I am now trying to make a connection to this database table through psycopg2 in Python on my local machine.
I used the command <code>docker-machine ip default</code> to find out the IP address of the machine as 192.168.99.100 and am using the following to try and connect:</p>
<pre><code>conn = psycopg2.connect("dbname='test-db' user='postgres' host='192.168.99.100' password='my_secret_password' port='5432'")
</code></pre>
<p>This is not working with the error message of "OperationalError: could not connect to server: Connection refused (0x0000274D/10061)"</p>
<p>.
.</p>
<p>Everything seems to be in order so I can't think why this would be refused.
According to the documentation for this postgres image, (at <a href="https://hub.docker.com/_/postgres/" rel="nofollow">https://hub.docker.com/_/postgres/</a>) this image includes EXPOSE 5432 (the postgres port) and the default username is postgres.</p>
<p>I also tried to get the IP address of the image itself with <code>docker inspect test-db | grep IPAddress | awk 'print{$2}' | tr -d '",'</code> that I found on SA to a slightly related article, but that IP address didn't work either.</p> | 1 |
Unable to detect adb version, adb output Unable to obtain debug bridge | <p>I am new to coding and have recently installed the latest version of Android Studio and the SDK package on my Mac OSX. I am receiving the error in the title when trying to run the basic "HelloWorld!" app. I know many have commented on this error, and I have tried putting earlier versions of the ADB file into my platform-tools folder but it did not fix the issue. I think it is because I am running it on OSX. As it is now, I have the adb execute file in my platform-tools folder in the right location, so I'm not sure why I am still having issues.

jquery ajax how should it format dates? | <p>I use jquery to communicate with a REST API. (ASP.net Web API).</p>
<p>I create a simple object and then use jquery to 'PUT' it on the server:</p>
<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>var myObject = {
name: 'just a name',
createDate: new Date()
}
$.ajax({
url: 'https://myServer/api/person/1',
dataType: 'json',
method: 'put',
data: myObject

</div>
</div>
</p>
<p>Looking at the network traffic in Firebug I can see that my createDate propery gets sent over the line as:</p>
<pre><code>Tue Feb 02 2016 14:40:26 GMT+0100 (W. Europe Standard Time)
</code></pre>
<p>This would be the default rendering of a <code>new Date().toString()</code></p>
<p>Not remarkably my API does not like this, it accepts dates in several formats and really handles the normal JSON version very well:</p>
<pre><code>new Date().toJSON()
results to: "2016-02-02T13:45:37.069Z"
</code></pre>
<p>How to deal with this? I would prefer not to have to post my object by 'manually' converting every date to JSON, this takes the whole ease of working with complex objects out of it.</p>
<p>What I could to (warning really dirty trick coming up), override the default toString method of the date object:</p>
<pre><code>Date.prototype.toString = new Date().toJSON
</code></pre>
<p>This works... but... YUCK!</p>

<p>My problem is that i cannot seem to be able to pass the WebDriver that is returned to the BrowserFunctions.java class on to the other classes in my test suite without having to create a new instance of WebDriver in each java file. I am looking to open the browser, open the URL, then run the 3 tests one after another in the same browser window, and have the browser close when done.</p> | 1 |
Better way to tokenize string in Ruby? | <p>I have a string of arbitrary characters. I would like to turn it into an array, where each character is in a single array element, EXCEPT of successive word-characters <code>(\w+)</code>, which should end up together in one array element. Example:</p>
<pre><code>ab.:u/87z
</code></pre>
<p>should become</p>
<pre><code>['ab','.',':','u','/','87z']
</code></pre>
<p>My first approach went like this:</p>
<pre><code>mystring.split(/\b/)
</code></pre>
<p>Of course this groups together non-word characters:</p>
<pre><code>['ab','.:','u','/','87','z']
</code></pre>
<p>I can take them apart in a subsequent step, but I'm looking for a more elegant way. Next I tried these:</p>
<pre><code>mystring.split(/(\w+|\W)/)
mystring.split(/(\b|\W)/)
</code></pre>
<p>Both return nearly the desired result, only that they also return array elements containing empty strings, so I have to write something like</p>
<pre><code>mystring.split(/(\b|\W)/).reject(&:empty?)
</code></pre>
<p>Now my question: Is there a simpler way to do this?</p>
<p><strong>UPDATE</strong>: I made a silly mistake when I explained my example. Of course '87' and 'z' should be together, i.e. '87z'. I fixed my example.</p> | 1 |
how to insert and update record through trigger in a custom object in salesforce | <p>Hi I have tried the below code </p>
<pre><code>trigger CreateRecord on Account (before insert,before update) {
List<Account> CreateAcc = new List<Account>();
For(Account acc:trigger.new)
{
acc.Name='abc';
CreateAcc.add(acc);
}
insert CreateAcc;
}
</code></pre>
<p>but the above code is creating the following error :
Review all error messages below to correct your data.
Apex trigger CreateRecord caused an unexpected exception, contact your administrator: CreateRecord: execution of BeforeInsert caused by: System.SObjectException: DML statement cannot operate on trigger.new or trigger.old: Trigger.CreateRecord: line 9, column 1<code>enter code here</code></p>

Converting hex values in buffer to integer | <p><strong>Background:</strong> I'm using node.js to get the volume setting from a device via serial connection. I need to obtain this data as an integer value.</p>
<p>I have the data in a buffer ('buf'), and am using readInt16BE() to convert to an int, as follows:</p>
<pre><code>console.log( buf )
console.log( buf.readInt16BE(0) )
</code></pre>
<p>Which gives me the following output as I adjust the external device:</p>
<pre><code><Buffer 00 7e>
126
<Buffer 00 7f>
127
<Buffer 01 00>
256
<Buffer 01 01>
257
<Buffer 01 02>
258
</code></pre>
<p><strong>Problem:</strong> All looks well until we reach 127, then we take a jump to 256. Maybe it's something to do with signed and unsigned integers - I don't know!</p>
<p>Unfortunately I have very limited documentation about the external device, I'm having to reverse engineer it! Is it possible it only sends a 7-bit value? Hopefully there is a way around this?</p>
<p>Regarding a solution - I must also be able to convert back from int to this format!</p>
<p><strong>Question:</strong> How can I create a sequential range of integers when 7F seems to be the largest value my device sends, which causes a big jump in my integer scale?</p>
<p>Thanks :)</p> | 1 |

Angular 2 - Post File to Web API | <p>I am attempting to pass a file to Web API from an Angular 2 app, and the actual file data does not get sent. </p>
<p>Here is my angular 2 service code: </p>
<pre><code> var headers = new Headers();
headers.append('Content-Type', 'multipart/form-data');
var formData = new FormData();
formData.append("file", file);
return this.http.post('http://myapiurl.com/files/upload', formData, { headers: headers }).map(res => res.json());
</code></pre>
<p>In the angular 2 docs, the POST method signature is as follows: </p>
<pre><code>post(url: string, body: string, options?: RequestOptionsArgs) : Observable<Response>
</code></pre>
<p>There is no option to pass Form Data, or other object. Just a string in the bodys request. The current work around is to use javascript and regular xhr requests. There are obvious downsides to this like not being able to use observables, etc. </p>
<p>Any help on this would be greatly appreciated. </p> | 1 |

Since there are another 70~80 lines of code following this callback, I wouldnt like to split the flow with an <code>if(error) <do the same stuff> else <as here></code></p>
<p>After trying for quite some time I ended up using a do-while(error) loop, which works but blocks. Is there an async way of doing this? </p>
<p>My code (simplified for generalization):</p>
<pre><code>//This is the request part
function bar(j, callback){
j++;
//simulated error
if(j<=10){
return( callback('dont', j) );
}
//simulated success
else{
return( callback(null, j) );
}
}
//This is the main function - part of a bigger piece in my code
function foo(){
var i = 0;
var err = 'yes'; //else we'd get an 'err is not defined'
do{
bar(i, function(error, j){
i = j
err = error;
if(error){
console.log(i);
}
else{
return( console.log('done it!') );
// There's more here in my code
}
});
} while (err);
console.log('I blocked');
}
foo();
</code></pre>
<p>Edit: </p>
<p>For those interested, this is the output: </p>
<pre><code>1

Wicket @SpringBean and Spring @Autowired with injection via constructor | <p>I have a Wicket panel in which I want to inject bean using @SpringBean</p>
<pre><code>public class SomePanel extends Panel {
@SpringBean
private BlogSummaryMailGenerator blogSummaryMailGenerator;
}
</code></pre>
<p>But this BlogSummaryMailGenerator has injection via constructor defined like this:</p>
<pre><code>@Component
public class BlogSummaryMailGenerator {
private BlogRepository blogRepository;
private BlogPostRepository blogPostRepository;
@Autowired
public BlogSummaryMailGenerator(BlogRepository blogRepository,
BlogPostRepository blogPostRepository) {
this.blogRepository = blogRepository;
this.blogPostRepository = blogPostRepository;
}
}
</code></pre>
<p>And when SomePanel is instantiated I am getting an exception</p>
<pre><code>Caused by: java.lang.IllegalArgumentException: Superclass has no null constructors but no arguments were given

</code></pre>
<p>Adding empty no-args constructor to the BlogSummaryMailGenerator solves this issue but adding such code only to make injection work is wrong and I would like to avoid it.</p>
<p>Any suggestions how to make @SpringBean work with beans using injection via constructor?</p> | 1 |
Docker container with non-root user deployed in Google Container Engine can not write to mounted GCE Persistent disk | <p>I'm playing with kubernetes and google container engine (GKE).</p>

<p>As you can see I mounted a Google Compute Engine Persistent Disk. My issue is that the container uses a non-root user and the mounted disk is owned by root. so my container can not write to the disk.</p>
<ul>
<li><strong>Is there a way to mount GCE persistent disks and make them read/write for containers without non-root users?</strong></li>
<li><strong>Another general question : is it safe to run container with root user in Google Container Engine?</strong></li>
</ul>
<p>Thank you in advance for your inputs</p> | 1 |
