3,489,142 | 3,489,143 | Parse JSON object one item at a time | <p>I am playing around for the first time with android development. I am trying to make a simple currency converter app. The particular piece I am working on is populating a spinner box with all of the available currencies without having to code it all in manually. I have a json file that looks like:<br>
<code>{<br>
"AED": "United Arab Emirates Dirham",<br>
"AFN": "Afghan Afghani",<br>
"ALL": "Albanian Lek",<br>
"AMD": "Armenian Dram",<br>
"ANG": "Netherlands Antillean Guilder",<br>
"AOA": "Angolan Kwanza",<br>
"ARS": "Argentine Peso",<br>
"AUD": "Australian Dollar",<br>
"AWG": "Aruban Florin",<br>
...<br>
}</code> </p>
<p>I want to read that object one currency at a time so I can use it to populate the spinner. Something along the lines of:</p>
<pre><code>/*PSEUDOCODE*/
spinner = (Spinner) findViewById(R.id.currencyTo);
List<String> list = new ArrayList<String>();
JSONParser jParser = new JSONParser();
JSONObject json = jParser.getJSONFromUrl(url);
while (rates != null) {
rates = json.getString(first item in json);
list.add(rates);
...
</code></pre>
<p>I know how to do it by calling each item individually, such as rates = json.getString("AED") and so on, but I don't want it so hardcoded like that. I want to parse each currency item individually, then place it in the spinner. Grab the next currency, place it in the spinner, and so on and so forth. Any help is greatly appreciated. </p>

3,768,321 | 3,768,322 | How to create a javascript class or module, I need 2 instances on a page | <p>I am wrapping common javascript functions that will work on elements on a page.</p>
<p>My page has 2 of these elements (textareas), so I will need to create 2 instances and then I want to do this:</p>
<pre><code>var textArea1 = new SomeClass();
var textArea2 = new SomeClass();
textArea1.init("ta1");
textArea2.init("ta2");
</code></pre>
<p>I tried doing this the module pattern way, but I'm confused how I can create 2 seperate instances of it?</p>

4,057,730 | 4,057,731 | Generate repeaters according to user inputs | <p>I have a DataList control on my webpage, the rows of which are populated by ItemTemplate. Each row has a check box, and on button click, I am generating as a string which is actually a <code>sql</code> query text.</p>
<p>Each result returned by the query from the DB has 10 rows which are to be shown in another DataList, as something like this:</p>
<pre><code><Header>
Item1: Result1
Item2: Result2
Item3: Result3
...
Item10: Result10
</code></pre>
<p>The problem is that I do not know how many checkboxes will be selected by the user, and according the number of results returned will be unknown.
So, if the user selects two checkboxes from the first DataList, the result DataList should have two columns:</p>
<pre><code><Header1> <Header2>
Item1: Result1 | Item 1: ResultCol2
Item2: Result2 | Item 2: ResultCol2
Item3: Result3 | Item 3:ResultCol2
...
Item10: Result10 | Item 10: ResultCol2
</code></pre>
<p>I tried to think of a solution for this. Let's say a user selects two check boxes:</p>
<pre><code>foreach checkbox selected by the user
Make a new repeater. Add a new header.
Fetch the data from the database (Each result contains 10 columns) and bind to the repeater.
Add the repeater to a container on the web page.
</code></pre>
<p>Now, I remember that in windows forms, such addition of runtime generated controls can be done by something like <code>TableLayout.Add(childElements)</code></p>
<p>But, I am not able to think of something similar in Web Forms. Is this actually the correct approach? How can this kind of dynamic building of DataControl achieved in this case?</p>

4,288,365 | 4,288,366 | How can I detect with JavaScript/jQuery if the user is currently active on the page? | <p>I am needing to detect when a user is inactive (not clicking or typing) on the current page for more than 30 minutes.</p>
<p>I thinking it might be best to use event blubbling attached to the body tag and then just keep resetting a timer for 30 minutes, but I'm not exactly sure how to create this.</p>
<p>I have jQuery available, although I'm not sure how much of this will actually use jQuery.</p>
<p><strong>Edit:</strong> I'm more needing to know if they are actively using the site, therefore clicking (changing fields or position within a field or selecting checkboxes/radios) or typing (in an input, textarea, etc). If they are in another tab or using another program, then my assumption is they are not using the site and therefore should be logged out (for security reasons).</p>
<p><strong>Edit #2:</strong> So everyone is clear, this is not at all for determining if the user is logged in, authenticated or anything. Right now the server will log the user out if they don't make a page request within 30 minutes. This functionality to prevent the times when someone spends >30 minutes filling in a form and then submitting the form only to find out that they haven't been logged out. Therefore, this will be used in combination with the server site to determine if the user is inactive (not clicking or typing). Basically, the deal is that after 25 minutes of idle, they will be presented with a dialog to enter their password. If they don't within 5 minutes, the system automatically logs them out as well as the server's session is logged out (next time a page is accessed, as with most sites).</p>
<p>The Javascript is only used as a warning to user. If JavaScript is disabled, then they won't get the warning and (along with most of the site not working) they will be logged out next time they request a new page.</p>

StreamReader sr = new StreamReader(data_file);
line = sr.ReadLine();
while (line != null)
{
elements = elements + 1;
line = sr.ReadLine();
}
sr.Close();
</code></pre>
<p>With this number I can now create an array of array by setting fist how many elements the array is going to hold. The array this time is going to hold the number from the file something like this:</p>
<p>datafile:</p>
<p>1,1</p>
<p>2,3</p>
<p>arrayL[0][0]=1</p>
<p>arrayL[0][1]=1</p>
<p>arrayL[1][0]=2</p>
<p>arrayL[1][0]=3</p>
<p>so the code to do this is the next:</p>
<pre><code>double [][] dime= new double [elements][];
string[] div;
string line2;
int nn=0;
StreamReader ssr = new StreamReader(data_file);
line2 = ssr.ReadLine();
while (line2 != null)
{
dimen[nn] = new double[2];
for (int m2 = 0; m2 < 2; m2++)

div=line2.Split(new Char[] { ' ', ',', '\t' });
dimenc[nn][m2] = Convert.ToDouble(div[m2]);
}
nn=nn+1;
line2 = ssr.ReadLine();
}
ssr.Close();
</code></pre>
<p>However, the array says that it is empty but I know if I used the second part of the code in a complete diferrent method/ second button but if it is in the same method it does not work so my question is: </p>
<p>What's wrong? Why the second streamreader is not working?</p>

<p>All works, fine, unless you go from one button to the other at which point you get many divs displaying at the same time until the delay passes. If we don't use the delay it works perfectly.</p>

<p>I assume i need to make one hover function aware of the other so it can cancel the timeout, i just have no clue how to do it. </p>

What I want to achieve is finding out the position of an element respect of the body, for instance, if the body text is 100 characters long and the text before the node is 50, that node would be at 50%.
Getting body's length is easy, but getting the text before an element is not as trivial as I'd thought in first instance.</p>

<p>To make it clear, I'll give an example:</p>
<pre><code><body>

...some text

<p>...some text...</p>
<p>...some text...</p>

<pre><code>foo()
{
int a;

<p>Now the question is for the best readbility, the init() function for foo(), should it look like</p>
<pre><code>void init()
{
a=b=c=d=1; //for some reason they are init to 1;

<p>?</p>
<p>The reason for a string in class is a hint of other groups of same types might present and of course, the class might grow as requirement changes</p>
<p>EDIT: before this question goes too far, the intention of this question was simple:
In Effective C++ item 12 (prefer initialization to assignment in constructors), Scott uses chain assignment instead of a=c; b=c; I am sure he knows when to use what, but I also remembered the books I read also recommended to use int a; int b; which in similar case of assignments. In my program I have a similar situation of a group of related individual build-in types needs to be initialized and I have found by making a chain assignment does makes it easier to read especially if the class have many other different types instance variables. It seems to contradict with books I read and my memory, hence the question.</p>

1,839,345 | 1,839,346 | How does one get a C++ library loaded into Python as a shared object file (.so)? | <p>I'm a Python guy building a Linux-based web service for a client who wants me to interface with a small C++ library that they're currently using with a bunch of Windows based VB applications.</p>
<p>They have assured me that the library is fairly simple (as far as they go I guess), and that they just need to know how best to compile and deliver it to me so that I can use it in Python under Linux.</p>
<p>I've read a bit about the <code>ctypes</code> library and other options (SWIG, etc), but for some reason I haven't really been able to wrap my head around the concept and still don't know how to tell them what I need.</p>
<p>I'm pretty sure having them re-write it with <code>Python.h</code>, etc is out, so I'm hoping there's a way I can simply have them compile it on Linux as a .so and just import it into Python. Is such a thing possible? How does one accomplish this?</p>

<table id="tab3" runat="server" visible="false" width="100%">
...
</table>
</ContentTemplate>
</asp:UpdatePanel>
</code></pre>
<p>then, I have a few buttons added to the page, and depending on which one is pressed, I'll change the table's visibility.
My problem is that, under certain conditions, I'm changing tab3's visibility to true, and tab1 and tab2's to false, and while tab1 will have it's visibility set to false, tab3 will not have it's visibility set to true... sigh!</p>
<pre><code>protected void Page_Load(object sender, EventArgs e)

{
...
if (!editMode)
{
tab1.Visible = false;
tab2.Visible = false;
tab3.Visible = true;
}
}

<p>in debug mode, as I go through these instructions, tab3.visibile = true will not change tab3's property!

2,178,637 | 2,178,638 | Creating my own callbacks | <p>I have a page with some jQuery, and a separate non-jQuery function.</p>
<p>Currently my function runs on $(document).ready, but I want to call a jQuery function as soon as my function is finished. I can pass my function as a callback to any jQuery function, but how can I set things up the other way round?</p>
<p>So I would ideally like to know how to create a function foo that will take care of this for me:</p>
<pre><code>$(document).ready(function() {
foo(myfunction(), $(bar).something);
}
</code></pre>
<p>or how to extend an existing function to handle callbacks. Thanks.</p>

2,735,385 | 2,735,386 | Get results from php script via jquery load() function before php script finishes | <p>I have the following situation:</p>
<p><b>jquery:</b></p>
<pre><code> $(function(){
$('input[type="button"]').click(function(){
$('#result').load('script.php');
});
});
</code></pre>
<p><strong>script.php:</strong></p>
<pre><code><?php
echo "1";
sleep(2);
echo "2";
sleep(2);
echo "3";
?>
</code></pre>
<p>Currently the jquery load function will wait for the php script to finish and then display the result into the targeted div...so in this case it will wait 4 seconds and then display 123.</p>
<p>What I'm trying to achieve is to have the jquery load function to return the results separately, live, before the php script finishes. By separately I mean to see in the targeted div 1 then wait for 2 seconds, then see 2, then another 2 seconds and then 3.</p>
<p>Is this possible with my example?</p>

737,580 | 737,581 | Why is the null coalescing operator breaking my string assignment in c#? | <p>I'm creating a query string in a web form, and I'm dealing with values from the parameters that might be null. There are lots of ways to check and fix these, but the most elegant one I found is the following:</p>
<pre><code>string pass;
pass = "BillabilityDetail.aspx?_startDate=" + _startDate.Text + "&_endDate=" + _endDate.Text +
"&_isContractor=" + _isContractor.SelectedValue + "&_busUnit=" + _busUnit.Text
+ "&_projectUnit=" + _projectUnit.SelectedValue + "&_leadCon=" + _leadCon.Value ?? -1
+ "&_acctExec=" + _acctExec.Value ?? -1 + "&_isBillable=" + _isBillable.SelectedValue +
"&_isActive=" + _isActive.SelectedValue + "&_include=" + _include.SelectedValue;
</code></pre>
<p>The only issue is... it doesn't work. When the code reaches this part, </p>
<pre><code>"&_leadCon=" + _leadCon.Value ?? -1 + "&_acctExec=" + _acctExec.Value ?? -1
</code></pre>
<p>the string stops assigning values. So the string would end with &_leadCon=.
I know of ways to work around this, but I don't know why it stopped working in the first place. Any tips?</p>

2,277,042 | 2,277,043 | jQuery slide changing with index and fadeout -- jumpiness | <p>I am working on a jQuery slideshow plugin. One of my methods involves switching back and forth between pictures. I have been pretty successful in creating it, here is an isolated case with the code thus far for the particular method:</p>
<pre><code>var images = $("#simpleslides").children("img");
$(".slideButtons ul li").on("click", "a", function() {
var anchorIndex = $(this).parent().index();
var $activeSlide = $("#simpleslides img:visible");
var $targetSlide = $(images[anchorIndex]);
if($activeSlide.attr("src") == $targetSlide.attr("src") || $targetSlide.is(":animated")) {
return false;
} else {
$activeSlide.css({ "z-index" : 0 });
$targetSlide.css({ "z-index" : 1 });
$targetSlide.stop().fadeIn("slow", function() {
$activeSlide.hide();
});
}
});
</code></pre>
<p>Here is a fiddle to see it in working action: <a href="http://jsfiddle.net/ase3E/" rel="nofollow">http://jsfiddle.net/ase3E/</a></p>
<p>For the most part, this works as you would expect it to. When a user clicks on the corresponding number, it fades in the picture. </p>
<p>However, I am running into some jumpiness and occasionally a complete <code>hide</code> of the slides when I am clicking around quickly. If you play with the fiddle, you will see what I am referring to Try clicking around on each image to see.</p>
<p>I have adopted <code>stop</code> which I thought would fix the problem but has not. I have put the <code>hide</code> method after the <code>fadeIn</code> callback, but that has also not helped the situation.</p>
<p>What am I doing wrong here??</p>

5,606,873 | 5,606,874 | FindControl inside Repeater | <p>I am trying to find a Label inside a Repeater, I am using:</p>
<pre><code> protected void lnkbtnEditRecord_Click(object sender, EventArgs e)

zipPanel.Visible = false;
ddlPanel.Visible = false;

frmViewSalesPeople.DataSource = dv;
frmViewSalesPeople.DataBind();
}

<p>This works great if the repeater only has one result, but if it has more then one it only gets the id for the first item listed. Any ideas on how to fix this?</p>
<p>EDIT: Basically the return is filled with user info and with each user info is a link to another page. So when I click the link I want to get the ID from the label for the record the link was clicked for. So If I click record 4 out of 5 I want and the ID for record 4 is 900 I want to get the 900 to pass.</p>
<p>Thanks!</p>
