What is causing a nullreference exception in this code?
|
<p>I try to add a new "Order" to my Session. I begin create a session in my Global.aspx file under Session_Start:</p>
<pre><code>Session.Add("Cart", new WebShopData.Order());
</code></pre>
<p>At my login page i make a new Session:</p>
<pre><code> Session["userID"] = "User";
((Order)Session["Cart"]).UserID = userID;
</code></pre>
<p>Then at my shop page i want to add stuff to the session:</p>
<pre><code> if ((Order)Session["Cart"] != null)
((Order)Session["Cart"]).OrderRow.Add(new OrderRows({ArticleID = 2, Quantity = 1) });
</code></pre>
<p>At this last line i get att nullreference exception. Why could that be?</p>
<hr>
<p>Here are my two classes:</p>
<pre><code> public class Order
{
public List<OrderRows> OrderRow { get; set; }
public string Address { get; set; }
public string City { get; set; }
public string Zip { get; set; }
public int UserID { get; set; }
}
public class OrderRows
{
public int ArticleID { get; set; }
public int Quantity { get; set; }
public override string ToString()
{
return string.Format("Artikel: {0}, Antal: {1}.\n", ArticleID, Quantity);
}
}

Show table cell on table row mouseover
|
<p>I have a table that looks something like this.</p>
<pre><code><table>
<thead>
<tr>
<th>Foo</th>
<th>Bar</th>
</tr>
</thead>
<tbody>
<tr class="data">
<td>Info here</th>
<td><a href"/url_here" class="edit">Edit</a></td>
</tr>
<tr class="data">
<td>More here</th>
<td><a href"/url_here" class="edit">Edit</a></td>
</tr>
</tbody>
</table>
</code></pre>
<p>I want to show the Edit link when you mouse over any of the rows inside of the . I have tried a few methods of doing this, but keep hitting the same problem. Assuming I'm just thinking about this the wrong way.</p>
<p>This is what I currently Have.</p>
<pre><code>$('a[class*=edit]').hide();
$('tr[class*=data]').bind("mouseover", function(e) {
$(e.target).closest('a[class*=edit]').addClass("selected");
$('a[class*=selected]:first').show();
}).mouseout(function() {
$('a[class*=selected]').hide();
$('a[class*=edit]').removeClass("selected");
})
</code></pre>
<p>Problem with the existing code is it's not adding the selected class unless you hover directly over the edit link. Like I mentioned above I need it to add the selected class when you mouse over anywhere in the that row. I also only want it to display the edit link for that specific row.</p>
<p>Any help would be really appreciated been pulling my hair out for a couple hours and I know it is probably something stupid. Thanks!</p>

move event handler with jQuery
|
<p>I have an issue which is driving me crazy and as a last resort I am placing a question here.</p>
<p>I want to move the onclick event from an element to the onfocus event of the same element and I am using the following code:</p>
<pre><code>$("#theElement").bind("focus", {}, $("#theElement").data("events").click);
$("#theElement").unbind("click");
</code></pre>
<p>Maybe you have guess it. IT DOES NOT WORK.</p>
<p>How do I make this work? I am getting a "fn.apply is not a function" message in the following piece of code from jquery 1.3.2:</p>
<pre><code>proxy: function( fn, proxy ){
proxy = proxy || function(){ return fn.apply(this, arguments); };
// Set the guid of unique handler to the same of original handler, so it can be removed
proxy.guid = fn.guid = fn.guid || proxy.guid || this.guid++;
// So proxy can be declared as an argument
return proxy;
}
</code></pre>
<p><strong>EDIT:</strong> I'm sorry, I should have mentioned. This comes from a plugin which does some stuff when clicking an element. I want to make the same thing when the element gets focus not when it is cliked so the simplest solution I thought off was this since I can't modify the code for the plugin.</p>
<p><strong>EDIT:</strong> Found the problem. It is similar to what @sje397 posted in his answer, not</p>
<pre><code>$('#theElement').data('events').click[0]
</code></pre>
<p>but</p>
<pre><code>$('#theElement').data('events').click[3]
</code></pre>
<p>For some reason, even if only one event is registered the thing ends up as 3 (the guid in that piece of code from jquery).</p>

Keyup event firing, change event not
|
<p>I am building a bunch of controls dynamically. </p>
<p>Essentially I am attaching a keyup to the textbox to detect when up/down is pressed in a table to move between cells. I am also watching for when the input field changes, because I then add that control to an array for posting back when the user hits save.</p>
<p>This works when I tab between controls or click from one control to the next. However, If I use the arrow keys as coded to move between fields, the change event does not fire.</p>
<p>My event handling code looks like this:</p>
<pre><code>$('input[id^="reo_"]').bind('change', function () {
rowDetailChange($(this));
});
$('input[id^="reo_"]').bind('keyup', function (e) {
processKeyUp($(this), e);
});

Android icon sometimes open new app sometimes brings up old app, help!

<p>I have an android app which i have written, which exhibits some strange behaviour. </p>
<p>When i have an app open, say with three acitivties in the stack</p>
<p>A - B - C</p>
<p>where a is the entry point and C is the currently viewed activity, if i press the home button and reselect the icon for my app sometimes i see A, which on pressing the back button i can see the task now contains the activities </p>
<p>A - B - C - A</p>
<p>and sometime it just reopens the app in the last state</p>
<p>A - B - C</p>
<p>which is what i want to happen. Could anyone inform me of why the inconsitant behaviour is happening. On both cases i press the icon strait after exiting the app via the home key. </p>
<h1>Thanks for any help!</h1>

jQuery - how to check if two elements are the same?
|
<p>I need to pass an element to a function and then match that specific element while traversing parent. The catch (for someone clueless like me) is that this element doesn't have an id. In the following example, I want every element to turn pink except the one clicked on that should turn yellow</p>
<pre><code>function colorize(element) {
element.parent().find('span').each(function() {
if ($(this)===element) { // the problem is this is always false
$(this).css('background','yellow');
} else {
$(this).css('background','pink');
}
});
}
$('span').click(function() {
colorize($(this));
});

Submit username and password javascript (not a form)
|
<p>I have a popup which asks the user for login information, which means two input text fields for password and username. </p>
<p>Now as I will be verifying the information using ajax I didn't wrap the elements on a because form always needs a php action, correct? or am I missing something?</p>
<p>So I'd like to know if there is a fancier way to check if the user pressed enter, in order to submit the login information, than checking each time a key is pressed, with keydown, if it's the enter key. </p>
<p>Thanks in advance</p>

Click event when not clicking on an element
|
<p>Maybe I'm, just tired but I have a right click menu that I want to close when the user clicks anywhere else than the menu. But I cant figure out how to make it disappear when the user clicks on something else.</p>
<p>Here is the code for showing the menu:</p>
<pre><code>// If mouse click on was pressed
$('#content_list table tr').bind('mouseup', function(event) {
// if right click
if(event.which == 3) {
showRightClickMenu(event);
}
event.preventDefault();
event.stopPropagation();
});
</code></pre>
<p>And this is what I got for hiding the menu</p>
<pre><code>// If mouse click outside document
$(document).bind('blur', function(event) {
hideRightClickMenu();
event.stopPropagation();
});
// If mouse click not on the menu
$('*:not(#rightClickMenu *)').bind('mousedown keydown', function(event) {
hideRightClickMenu();
event.stopPropagation();
});
</code></pre>
<p>The first bind checks if the user clicks outside the document and the second bind checks if the user clicks on everything except the menu.
But the second one doesn't really work. If I click on the menu the menu is hidden.</p>
<p>Shouldn't be so hard imo... Anyone got any ideas?</p>

Jquery Selector in Horizontal Accordion
|
<p>I'm Trying to build a simple horizontal accordion that will eventually contain more complex data (iframes)... The problem is that I want the size of each accordion tab to be specific to the data it contains, so I'm trying to edit what's already out there (Some tabs are larger than others). When a user hovers over any tab I want to expand that tab to 50% (regardless of its previous size). All that is working fine, but the problem is I can't figure out how to go back to the tabs ORIGINAL width after mouseout. Right now I have the panels shrinking to 10% to illustrate the problem. If you cycle through the page then reload you will see what i mean. Any ideas?</p>

Multiple classes extending Application
|
<h1>two classes extend Application</h1>
<ul>
<li>One class I've registered in the Manifest and am using as an <code>Application</code> is meant to be </li>
<li>Second class is my utilities class. It does lots of I/O and has a few helper methods. For I/O you need context (getAssets etc), so I reluctantly extended Application.</li>
</ul>
<p><em><strong>Note:</em></strong></p>
<blockquote>
<p>Everything is working as it should.</p>
</blockquote>
<p><em><strong>My Question:</em></strong></p>
<p>Are there any drawbacks of using multiple Application classes? Is this even advised?</p>
<p><strong>A few thoughts:</strong></p>
<ul>
<li>Like what would happen if I had onCreate and other callback methods defined in both the classes? </li>
<li>How do I register them both in the manifest even?
etc </li>
</ul>
<p>PS: I know I can just use a field to store context in the second class.</p>

Detect when HTML has finished loading AND rendering on the page
|
<p>Is it possible to detect when HTML has finished loading AND rendering on the page? If so, how?</p>
<p>The page consists of HTML, calls to ajax, receives data back from ajax calls, lots of javascript stuff and some images too. I would like to detect when everything has finished. What I can't do is stick a function call at the end, because I don't know when the end is.</p>
<p>For example, the page has lots of ajax style elements which users can pick and choose from, i.e. user 1 might have a different number of elements than user 2 and even in a different order.</p>
<p>So what I can't do is use the last function to simulate the end of HTML rendering, because I won't know which function will be the last function.</p>

What is a good project / way for an out of practice C++ developer to get back into it?
|
<p>Like many people here, I started my programming experience with the good ol' green screen BASIC that you get when you booted an Apple II without a disk. I taught myself C++ in my teens, and even took a class on it in college, but as soon as I discovered .NET and C#, I dropped C++ like a bad habit. Now, (many) years later, I'm interested in getting back into C++ development - thank the iPhone for that - and I have to admit, I feel a little daunted. Having to deal with pointers, ATL, macros, etc. seems a bit overwhelming at times when you've been in managed .NET land for a long time. </p>
<p>What are some good resources or weekend type projects I could do to ease me back into C++? I'm not interested in debating the relative merits between platforms, stacks, but I would be interested in hearing about <em>objective</em> comparisons between different development platforms, although keep in mind I'm a Windows guy.</p>
<p>If anyone wants to change the tags around, feel free - I wasn't quite sure how to tag this.</p>
<p>TIA!</p>

<p>In this Herb Sutter's article '<a href="http://www.gotw.ca/publications/advice97.htm" rel="nofollow">Write What You Know, and Know What You Write</a>', he warns about the dangerous idioms in C++.</p>

{
if( this != &other )
{
this->~T();
new (this) T(other);
}
return *this;

<p>Does C# solve this kind of dangerous cases? Is C# a better programming language than C++ in terms of having less dangerous idioms?</p>

Jquery simple menu
|
<p>I need to create a menu same as this one:</p>
<p><a href="http://www.girard-perregaux.com/collection/univers-en.aspx?type=1" rel="nofollow">http://www.girard-perregaux.com/collection/univers-en.aspx?type=1</a></p>
<p>Click on collections then on manufacturer, then again on manufacturer to close. As you can see first it slides down, then after that it just change links without again sliding up and down, untill you click on same open element.</p>
<p>I first tried this:</p>
<pre><code>$('ul.sub-menu').hide();
$('.sf-menu').children('li').click(function(){
$(this).children(".sub-menu").slideToggle('slow');
$('ul.sub-menu').hide();
</code></pre>
<p>its working but its sliding up and down every time you click on menu, and not just changing list items. So I figured out I need to somehow target child li elements instead of ul. Also if you click between parrent list items, it needs to switch like on that menu, but if i click again on same open list item, it needs to close(slide up.)</p>
<p>Many thanks for this as I spent half a day trying to figure it out. Also how to target children li, i tried this:</p>
<pre><code>$('.sf-menu').children('li').click(function(){
$(this).children(".sub-menu li")
</code></pre>
<p>but nothing.</p>

Advice for C# programmer writing Python
|
<p>I've mainly been doing C# development for the past few years but recently started to do a bit of Python (not Iron Python). But I'm not sure if I've made the mental leap to Python...I kind of feel I'm trying to do things as I would in C#.</p>
<p>Any advice on how I can fully take advantage of Python?</p>
<p>Or any tips\tricks, things to learn more about, things to watch out for?</p>

Not Adding Record with "Space"
|
<p>I'm using direct url to a record in my database, but my problem was, when the records contains " " or "space" it didn't save. for example:</p>
<blockquote>
<p>name = "Lebron" this is working.</p>
<p>name = "Lebron James" </p>
</blockquote>
<p>this will not work because of the space between first and last name. Did anyone already encountered this type of error?</p>

Why does my Javascript return [object HTMLScriptElement] instead of expected text?
|
<p>I am having similar issues from</p>
<p><a href="http://stackoverflow.com/questions/2222417/unable-to-run-an-external-javascript-using-a-bookmarklet">unable to run an external javascript using a bookmarklet</a>.</p>
<p>But I am executing my JavaScript inside a Java application via injecting script headers into the current DOM loaded via Java application.</p>
<p>This problem seems to occur randomly. Some cases it returns <code>[object HTMLScriptElement]</code> and other times returns the text...</p>
<p>When I <code>alert()</code> the object, it returns text! </p>
<p>I have tried <code>return String(hi);</code> but still no effect.</p>
<pre><code>function returnsomeText(){
var hi = someArray.join(':');
alert(hi); //returns text:text:text:text as expected.
return hi; //returns [object HTMLScriptElement]
}
</code></pre>
<p>I am very confused to as what is causing this problem! If JavaScript returns <code>[object HTMLScriptElement]</code> then my Java application cannot process the text.</p>
<p>This question is in more detail here:</p>
<p><a href="http://stackoverflow.com/questions/4732618/exception-in-thread-awt-eventqueue-0-java-lang-nullpointerexception-when-trying">Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException when trying to execute Javascript</a></p>

Jquery Focus on input field
|
<p>I have this code working on a page that literally just has 20 input fields each named and id'ed 1 through 20.</p>
<p>If I set the variable id to the next id. E.g current fields id +1 then it will focus on that field. But at the moment when you click out of the current input it will not focus back onto the one you were last typing in if the number entered is over 10, but the alert will fire.</p>
<p>Any help is appreciated.</p>
<pre><code>$(":input").focusout(function(){
var input = $(this).val();
var id = $(this).attr('id');
if(input > 10){
alert('You must enter a number between 0 and 10 '+id);
$("#"+id).select();

Delete everything inside a tag but another tag jquery

<p>I have this piece of html </p>
<pre><code> <div id="Cart">
<p>
You have <strong>1</strong> item in your cart.
Your sub total is <strong>$35.00</strong>.
</p>
</div>
</code></pre>
<p>I need to be able to get the information between the <code><strongs></code> and delete everything else, is that possible with jquery? I tried <code>$("#Cart strong:not()")</code> But didn't select anything, I thought maybe placing the info in a variable, deleting everything with .remove and reprinting the variables but I don't really know how to do that, can someone help me?.</p>
<p>The information between the strong is dynamic, I believe all the other is in a php file that I dont have access to... maybe filtering the words and removing them? Any advice will be welcome :)</p>

How do I tie in my image handler with an image control?
|
<p>I've been looking around and reading about handlers, but I don't fully understand how to implement them for my situation.</p>
<p>I want display a screenshot from the user's clipboard. I already have code that retrieves the image from the clipboard into a bitmap format. This is what I have:</p>
<pre><code>var dataobj = new DataObject();
dataobj = (DataObject)Clipboard.GetDataObject();
System.Drawing.Image img = dataobj.GetData(DataFormats.Bitmap) as System.Drawing.Image;
original = (System.Drawing.Image)img.Clone();
img = resizeImage(img, new Size(670, 500));
String s = "c:/Temp/temp.png";
img.Save(s, ImageFormat.Png);
Image1.ImageUrl = s;
Image1.DataBind();
</code></pre>
<p>My problem was that I am not able to save the images to the hard disk.</p>
<p>My first question is will an image handler help me in this situation?</p>
<p>if it will, how do I modify that code and tie it into my image handler with this code:</p>
<pre><code>public class getmyimage : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
HttpResponse r = context.Response;
r.ContentType = "image/png";
// Write the requested image
r.WriteFile("temp.png");
}
public bool IsReusable
{
get { return false; }

javascript test if URL relative or absolute and not mailto:
|
<p>I have tables with buttons/links/email with mailto: and have written a default double click function which on double click of the row will direct the user to the last link in the table. </p>
<p>99% of tables will have the Edit button in the last column.</p>
<pre><code>$('table:not(.noDoubleClick) tr td').dblclick(function() {
var linkEl = $(this).parents('tr').find('td:last-child a');
if(!linkEl.length){
return false;
}
if (linkEl.attr('href') && linkEl.attr('onclick') === undefined && !linkEl.hasClass("popme")) {
document.location = linkEl.attr('href');
} else {
linkEl.click();
}
});
</code></pre>
<p>This works fine until I have a rare table where the last column is a email address with a mailto. </p>
<p><strong>Q:</strong> How could I check if the href is relative/absolute link only. So that this would exclude mailto: and any other links which are not standard URLs.</p>
<p>I know I could do something like this: <code>linkEl.attr('href').substring(0, 7) == "mailto:"</code> to test specifically for mailto but is there a better way of doing this without a load of IFs testing for the different protocols to be excluded. </p>
<p>Update with working solution from @epascarello:</p>
<pre><code>$('table:not(.noDoubleClick) tr td').dblclick(function(e) {
var linkEl = $(this).parents('tr').find('td:last-child a');
var linkElHref = linkEl.attr('href');
// Check if has href and http protocol
if(!linkElHref.length || this.protocol.indexOf("http") !== 0){
e.preventDefault();
return false;
}
if (linkElHref && linkEl.attr('onclick') === undefined && !linkEl.hasClass("popme")) {
document.location = linkElHref;
} else {
linkEl.click();
}
});
</code></pre>

Android OnDraw() and update with Timer

<p>I'm trying to make a game in Android that once a user presses start, there will be objects flying across the screen. I think I need to link my OnDraw() function with a timer so that the objects' positions can be updated. </p>
<p>Currently, I am following a code sample I found online that prints out the text continuously.
However, I can't import java.awt.event.ActionEvent and ActionListener. Eclipse is giving me a "The import java.awt.event cannot be resolved". Is there an Android equivalent to ActionEvent?
Or is this done some other way? Thank you.</p>
<pre><code>import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.Timer;
public class TimerSample {
public static void main(String args[]) {
ActionListener actionListener = new ActionListener() {
public void actionPerformed(ActionEvent actionEvent) {
System.out.println("Hello World Timer");
}
};
Timer timer = new Timer(500, actionListener);
timer.start();
}

<p>Firstly, the user sets a price on the first slider, then the user uses a second slider to set the number of customers allowed to purchase and item, the second slider should output only whole numbers from the calculation.</p>
<p>For example. Price is set to £50. Then second slider should then output 1,2,5,10,25,50 as these are the only whole numbers from the calculation.</p>

Fastest way to set a css property?
|
<p>I'm busy creating a resizer, but on reloading it first switches from 100% until loading the cookie and setting the width to something fixed:</p>
<pre><code>//set width from cookie, unfortunately we need todo this on docready because #main-container is not done rendering -_-
var width = $.cookie("width");
// Set the user's selection for the left column
if (width != null) {
if (width == "fluid") {
alert("fluid!");
$('#main-container').addClass('width-fluid');
} else {
$('#main-container').addClass('width-fixed');
}
} else {
$('#main-container').addClass('width-fixed');
};
</code></pre>
<p>Any ideas?</p>

How do I get the previous HTML text prior to a node?
|
<p>UPDATE:<br>
Someone asked: <em>for what purpose would I want to do this?</em><br>
I'm trying to get the string index of a selected node server side, and since I have to account for repetition of small selections / nodes, I figure getting all html prior to the selected node on the client side would help in being the most accurate way to get the index.</p>
<p>lets say I have html like this:</p>
<pre><code><tag>
<child>
<subchild>
</subchild>
</child>
</tag>
</code></pre>
<p>and I "select" subchild.
I want to get all preceeding HTML as text** prior to that node.. so, in this case that would be:</p>
<pre><code><tag>
<child>
</code></pre>
<p>is there a slick, easy way to do that?</p>
<p>** I specify "as text" because, using jQuery / modern browsers, incomplete tags would become valid, as jQuery tries to make sure things don't break. Since I would not doing DOM manipulation with this information, I don't need valid HTML syntax.</p>

Sending an array as a server tag's property
|
<p>I am wondering if it's possible to send an array of strings to a tag's property</p>
<pre><code><SampleTag:Form
runat="server"
ID="sampleform1"
Items={item1,item2,item3,item4}
>
</SampleTag:Form>
</code></pre>
<p>This doesn't work since it sends "{item1,item2,item3,item4}" as a string to the class.</p>

Get device/model information from Android via Python
|
<p>Good day all!</p>
<p>Hoping one of you Gurus can help me out with this issue.</p>
<p>I am currently writing an app in Python which pulls device manuals from their websites and creates a User Manual shortcut for it to be launched.</p>
<p>So far so good, but in the long run I would like to set it up to pull the manufacturer/model number from the Android OS and search according to the specific model.</p>
<p>The problem? I can't for the life of me find anything Pythonic that can pull such information from the system? From searching Google, I was able to find out that in native languages, they can access android.os.Build to obtain such information but I cannot figure out how to access this via Python?</p>
<p>Any suggestions would be greatly appreciated!</p>

Textbox losing value after postback
|
<p>My page is a registration page, where a user enters an e-mail address and password. Here is my click event:</p>
<pre><code>protected void btnRegister_Click(object sender, EventArgs e)
{
MembershipCreateStatus createStatus = MembershipCreateStatus.ProviderError;
MembershipUser user = Membership.CreateUser(txtUsername.Text,
txtPassword.Text, txtEmail.Text, null, null, true, out createStatus);
if (createStatus != MembershipCreateStatus.Success)
{
cvUser.IsValid = false;
cvUser.ErrorMessage = "Invalid";
}
else
Response.Redirect("Home");
}
</code></pre>
<p>Here is my page:</p>
<pre><code><asp:ValidationSummary ID="vs" runat="server" />
<asp:TextBox ID="txtUsername" runat="server" />
<asp:TextBox ID="txtEmail" runat="server" />
<asp:TextBox ID="txtPassword" runat="server" TextMode="Password" />
<asp:Button ID="btnRegister" runat="server" OnClick="btnRegister_Click" />
<asp:CustomValidator ID="cvUser" runat="server" ControlToValidate="txtEmail" />
</code></pre>
<p><code>cvUser</code> is a custom validator on my page that I'm using so that the error message will show up on my <code>ValidationSummary</code>.</p>
<p>So the problem occurs when the user creation fails. I set <code>cvUser.IsValid</code> to false so that the error will show, and then the page reloads. Only when the page reloads, all the data in my textboxes is gone.</p>
<p>Is there a way to maintain that data?</p>

How to make Android Buttons show animation on itself when clicked

<animation-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/one" android:duration="500" />

AnimationDrawable frameAnimation = (AnimationDrawable) b_button.getBackground();
frameAnimation.setOneShot(true);
frameAnimation.start();
</code></pre>
<p>When I press the button, the animation would be played, however, for just once, after when I press it the second time, it will not play. Furthermore, how do I change the button back to it's original state? Meaning the grey default look of the button.</p>

How to communicate with a car via Android smartphone?

<p>I want to start an app to be used by an Android smartphone to send information to a car. One example would be to unlock the car, but that is not precisly what I want to do is just an example. My question is, how can I communicate with the car? I am thinking of using a webservice, don't know if this would be adecuate for the prototype.</p>
<p>I would appreciate some links, or info to point me in the right direction to enable a communication of some sort with the car, that is adding a modem to the car or something, I don't know much about how to be able to communicate. </p>
<p>Is there a way to communicate in a longer distance, that is not using bluetooth, since bluetooth is for short distances?</p>

Problem with jQuery - error when trying to find 2 tags
|
<p>I have the following DOM structure:</p>
<pre><code>/*:DOC += <div id='testDiv' class='testDivClass'><div id='innerTestDiv'></div></div><span id='testSpan' class='testSpanClass'><span id='innerTestSpan'></span></span>
</code></pre>
<p>Now I tried to run jQuery select against them as follow. The first one returned alright, but the second one failed:</p>
<pre><code>// works
var result = $('#testDiv')[0];
alert(result.id);
// failed: id is null or not an object
var result2 = $('#testSpan')[0];
alert(result2.id);
</code></pre>
<p>I tried selecting id instead of class and got the same results.</p>
<p>My question is: how can I get the second select to work? Is there some sort of invisible iterator/pointer in jQuery which I need to reset to the beginning of the DOM before the second select?</p>
<p>Thanks.</p>
<p>EDIT: Ok this is the official "does not work" version. testDiv matched, but testSpan did not, hence I got an error saying id is null or not an object error in the second alert.</p>
<p>UPDATE: I did a test by swapping testDiv and testSpan in the html. Now BOTH select failed.</p>
<p>UPDATE2: I have changed the html back to what it used to look like. I'm using JsTestDriver to write up the test, but it is actually not calling anything at the moment. The actual html looks messier than this (more nested tags). I'm trying to get this simplified version to work first. It appears that jQuery was able to get into the first select, whether it'll be span or div, but couldnt get out of it to do the second select. I've replaced jQuery.js and jsTestDriver.jar to no avail.</p>
<p>Thanks.</p>

Using a constant variable in C++
|
<p>I have a C++ file in my C++ project in Visual Studio.
The C++ file has a snippet wherein some applications are run using <code>system</code></p>
<pre><code>system("Files\\tx1");
system("Files\\tx2");
system("Files\\tx3");
system("Files\\tx4");
</code></pre>
<p>I want to replace the "Files" constant with some constant variable which can be changed at a single place. Something like what we wuld do in C# with app.config files etc.<br/>
Directly hardcoding a constant is not a good practice. C++ project doesn't have settings file unlike C# projects. So, any suggestions what I should do in this case?</p>

change border/color onFocus
|
<p>I tried to make script which changes color of border-bottom of div after having focus on </p>
<pre><code><input type="text">
</code></pre>
<p>and then changing back to default color after clicking somewhere else.</p>
<p>This is what i tried:</p>
<p>Css:</p>
<pre><code>.div1 {border-bottom:1px solid #ccc;}
</code></pre>
<p>Javacript: </p>
<pre><code>function inputFocus(){ $(".div1").css("border-bottom","1px solid #ffba00"); };
</code></pre>
<p>Html: </p>
<pre><code><input type="text" onFocus="inputFocus();">
</code></pre>
<p>The first part (changing color on focus) works fine, however after clicking somewhere else (not having focus on input) it doesnt change back to normal style as set in css file.</p>
<p>any idea what im doing wrong?</p>

Adding data to element so jQuery can use it
|
<p>I'm looking for an elegant way to add data to an element on server side so that jQuery/JavaScript can use it. I also do not want to make too many calls to server so data must be there upfront.</p>
<p>Scenario example.
Server side (PHP), I create a list of user images. To this, I want to add name, surname, age, etc.<br />
When clicking on the images, jQuery must then do something with this data.</p>
<p>Possibilities I've considered:<br />
Have the data as href, then on click, get the href and return false.<br />
Have the data as classes. </p>
<p>Are there any better ways?</p>

JQuery: How to stop child onclick event while still triggering the parent onclick event
|
<p>I wonder how can I stop child onclick event while still triggering the parent onclick event. For example the following structure:</p>
<pre><code><div id="parent">
<div id="child1"></div>
<div id="child2"></div>
<div id="child3"></div>
</div>
</code></pre>
<p>if I click "child1" for example, the onclick event for "child1" will not be triggered, however, the onclick event for "parent" will still be triggered.</p>
<p>Thank you very much!</p>

How to synchronize jQuery dialog box to act like alert() of Javascript
|
<p>I am currently working on developing custom dialog box to be used with my application using jQuery. The problem is that the call to create dialog is asynchronous i.e. the line of code after it is executed before it is displayed. Here is what I have done, I have created a function DisplayConfirm() which when called creates a modal dialog. I want to use it like the following:</p>
<pre><code>if(DisplayConfirm()){
//do this
else
// do that
</code></pre>
<p>But I cannot because the line of code written after DisplayConfirm() is executed before the dialog is even created. How can I synchronize this operation so that I don't have to use callback functions?</p>

Visual web part dynamic controls findcontrol in dynamic created control not works
|
<p>I have a problem with dynamic controls. In Button1 postback I created several TextBox controls like that:</p>
<pre><code>TableCell c = new TableCell();
TextBox tb = new TextBox();
tb.ID = "RTB_"+re;
c.Controls.Add(tb);
</code></pre>
<p>On button2 postback I would like to get a thesis controls input data, but I did not get anything that could be a fault and of course I need rebuild these controls</p>
<pre><code>foreach (string ctl in page.Request.Form.AllKeys)
{
try
{
TextBox text = page.FindControl(ctl) as TextBox;
if (text != null)
{
string t = text.Text;
}
}
catch { }
}
</code></pre>
<p>How can I get and put new values in my controls?</p>
