3,703,478 | 3,703,479 | JQuery’s $(document).ready is not always being called, is it a known issue? | <p>I am testing my script in IE9. I noticed that $(document).ready is not always being called. That means 1 out of 8 times the function referred by $(document).ready is not being called.</p>
<p>As soon as I move the $(document).ready call to the end of the document, it works perfectly. The problem arises only if I move the $(document).ready call to the section.</p>
<p>I read through the blog post that confirms this problem in IE6:
<a href="http://webbugtrack.blogspot.ca/2007/08/bug-153-self-closing-script-tag-issues.html" rel="nofollow">http://webbugtrack.blogspot.ca/2007/08/bug-153-self-closing-script-tag-issues.html</a></p>
<p>Considering the reputation of JQuery, I am surprised by the issue. Is this a known issue/bug and workaround for JQuery? Or am I missing anything?</p>
<p>Thank you,</p>
<p>UPDATE:</p>
<p>I just wanted to update with regards to this issue:</p>
<p>The script was working fine on the other browsers (Chrome and FF), only my dev machine's IE was problematic. Once I reset IE (reset and restore on the IS settings’ advanced tab) $(document).ready started to work as expected. So I know the solution, but I like to know the root cause.</p>
<p>While I am disappointed on IE’s shaky behavior, this case is left with an unanswered question:
One of IE’s setting changes the way that $(document).ready behaves, and it causes the problem I explained in this post. Does anybody know which setting cased this issue?</p>

918,570 | 918,571 | Android: How to use an xml string value to determine layout orientation | <p>I have a simple linear layout that I would like to change based on the screen size of the device. What I am trying to do is something like</p>
<p><code>
LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"<br>
android:orientation="@string/cover_orientation"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</code></p>
<p>I have created different dimen.xml files under values and values-xlarge so that the <code>cover_orientation</code> variable will take on a different value (either 'vertical' or 'horizontal') based on the screen size. </p>
<p><code>
string name="cover_orientation">"vertical"
</code></p>
<p>But this doesn't work. I have found a temporary work around that involves checking the screen size and changing the orientation manually:</p>
<p><code>
if(getResources().getString(R.string.screen_size) == "xlarge"){
((LinearLayout)convertView).setOrientation(1);
}
</code></p>
<p>but it seems like you should be able to do it the first way (much more elegant/less code).</p>
<p>I considered just having a different layout for each screen size, but the layout is actually quite big and this is the only change I need for the different screen sizes. So it didn't make much sense to me to duplicate the entire layout.</p>
<p>Thanks!</p>

<p>This is of course inefficient and I would like to figure out a way to inflate the subview only once and then reusing them instead. Is this possible somehow?</p>
<p>PS: I do not want to build up the subviews in code (I know I could) because that would make things even messier due to the complexities and number of subviews, but if the performance would increase considerably I might take a look at that.</p>
<p>PPS: There is no visible performance problem but traceview that most of the time is spent inflating and if I can make it faster I would love to ;-)</p>

<p>So in my findSiblingWithId i don't know the id I'm looking for, all I know is that for the other components in the same div, only one will have an id. How can I get that ? </p>
<p>Edit:
Since it seems I didnt explain well enough I'll try to add more info. So I want for example when the select component changes (here it could be a button or anything, it doesnt matter) to get the corresponding <code><input id="some other id" ..></code> from the same div.</p>
<p>Like I tried to explain above, I have one huge div, the <code><div id="some id"></code>, now this contains a number of smaller <code><div></code> without ids. </p>
<p>Each of these smaller divs will have ONE inputfield with an ID and a bunch of other without an ID. Now on an action, doesn't matter if a button click or whatever, from a component located IN THE SAME div (I thought the correct work would be 'sibling') is there a way I can find the input that has an ID attribute?</p>

4,644,358 | 4,644,359 | defineGetter & defineSetter on CSSStyleDeclaration.prototype | <p>I want to implement a fake style named <code>myColor</code> on all elements. When setting <code>myColor</code> style on the element, the actual <code>color</code> should be set with the same value. The apparent way of doing this is to use <code>__defineSetter__</code> and <code>__defineGetter__</code> on <code>CSSStyleDeclaration.prototype</code>.</p>
<p>Here is my implementation <a href="http://jsfiddle.net/ghostoy/jJ2GC/" rel="nofollow">http://jsfiddle.net/ghostoy/jJ2GC/</a> and the expected result is once clicked <strong>SetMyColor</strong> button, the color of the text changed to red and show me "Set color to: red". However, the setter is not invoked as expected.</p>
<p><strong>== Updated ==</strong></p>
<p>On different browsers (webkit/mozilla/msie), they use different prefixed style names for non-standard styles. For example, Chrome uses <code>webkitTransition</code>, Firefox uses <code>mozTransition</code> and MSIE use <code>msTransition</code>. However, I want apps that use <code>msTransition</code> can run correctly on Chrome with <code>webkitTransition</code> without modification.</p>
<p>My question is:</p>
<ol>
<li>Why my setter is not invoked?</li>
<li>How to implement such fake style?</li>

$trailhead->park_id = $row['park_id'];

super.onScrollChanged(l, t, oldl, oldt);

int offset = (int) (OFFSET*(getScale()));
if(getScrollY()+offset >= getScale()*(getContentHeight() - getHeight()) || t-offset<= 0){ panel.setVisible();
}else{

872,015 | 872,016 | jQuery Click Event PreventDefault | <p>If I have an <code>a</code> tag:</p>
<pre><code><a id="delete-event" href="/delete/1234">Delete</a>
</code></pre>
<p>And some javascript which prompts to confirm the delete:</p>
<pre><code> $("#delete-event").click(function(e) {
e.preventDefault();
bootbox.confirm("Are you sure you wish to delete this?", function(confirmed) {
if(confirmed) {
return true;
}
});

<p>I thought doing <code>e.preventDefault()</code> would prevent the <code>a href</code> from firing, but its not. When I click the a tag it simply goes to the url, without executing the javascript. How can I make this work?</p>

582,971 | 582,972 | Looping objects then deleting them | <p>Hey I have a simple loop which iterates a bunch of objects and checks if they match a variable and if they do, I want to remove it from the that list.</p>
<p>But i don't know how to do it... this is the idea of what I am trying to do :</p>
<pre><code>//my_objects is global (window.my_objects)
for(var i in my_objects){
if(my_objects[i].value == 100){
//remove it
}
}
</code></pre>
<p>Is there any option besides creating an array for it ? I could only find <code>delete</code> which only deletes the property which means the object will still be itereated through my loop next time around.</p>

5,076,349 | 5,076,350 | Pure virtual function vs. virtual function? | <p>I'm developing a class with some functionality that I think might need to be extended later, but not now. If the class were to be extended, then I think this would make instantiating the base class meaningless. </p>
<p>For example, let's say my base class is a tree. One approach would be to just put everything that the tree needs to do for my purposes in the tree class and leave it at that. However, this tree might be useful in other aspects of the program later on in life, so I've thought about creating a pure virtual <code>onNodeVisited</code> function. Derived classes could then implement their own version of <code>onNodeVisited</code>, and not have to worry about the specifics of the tree traversal defined in the based class.</p>
<p>Does it make sense to not use a pure virtual function and keep the tree functionality and application-specific functionality in one class (virtual <code>onNodeVisited</code>)? Or, should I make the tree class abstract and implement one sub-class for the application-specific part.</p>

3,501,611 | 3,501,612 | DLL doesn't store string C# | <p>I have an application that can be launched from the explorer context menu for a Windows drive. When you click the menu item the drive letter is passed to the new instance. I want to make sure that any old instance is closed.</p>
<p>I also want to make sure that the last drive that was selected is persisted, so that when I start the application again from the start-menu, it will remember the drive I originally selected.</p>
<p>It would be best if the already running application would receive an event so that it can update without having to kill and restart.</p>
<hr>
<p>I tried the following, but that doesn't seem to be working:</p>
<p>This is my Class library method(it is just a line that define a variable so just i have a DLL that there a variable in it and no more) </p>
<pre><code> namespace Dispatch
{
public class cls_get_drive_letter
{
public static string drive_letter;
}
}
</code></pre>
<p>This is my loading form code: (Here i will fill the DLL's variable)</p>
<pre><code> private void Frm_loading_Load(object sender, EventArgs e)
{
Dispatch.cls_get_drive_letter.drive_letter = "XXX";
Process currentProcess = Process.GetCurrentProcess();
if (Process.GetProcessesByName(currentProcess.ProcessName, currentProcess.MachineName).Length >1)
{
currentProcess.Kill();
}
}
</code></pre>
<p>So when i run this for first time the "XXX" will be stored in DLL but when the current instance of application is running and i am going to run next instance of it the application will be closed because of this code:</p>
<pre><code> Process currentProcess = Process.GetCurrentProcess();
if (Process.GetProcessesByName(currentProcess.ProcessName, currentProcess.MachineName).Length >1)
{
currentProcess.Kill();
}
</code></pre>
<p>So when closing code occurs with this code the new "XXX" will not stored in DLL and the last string will be in dll.</p>

4,960,604 | 4,960,605 | Slow recursive destructor call in C++ | <p>I am using C++ do represent large graphs using reference counted objects. Something like:</p>
<pre><code>// Public class
class Pointer{
public:
// Constructors
Pointer(...){ node = ...; node->counter++;}
// Copy constructor
Pointer(Pointer& const other){ node = other.node; node->counter++;}
// Destructor
~Point(){ if(--node->counter==0) delete node;}
// Other methods
...
Node* node;
};
// Node base class
class Node{
// Constructor
Node():counter(0){}
// Destructor
virtual ~Node(){}
// public:
unsigned long counter;
};
// Node derived class
class NodeDerived : public Node{
// Constructors and other methods
...
// Destructor
virtual ~NodeDerived(){ ... }
// Children
Pointer children[2];
};
</code></pre>
<p>There is thus a public class <code>Pointer</code> which contains a pointer to a polymorphic class Node. Some classes derived from Node will contain new <code>Pointer</code> instances. Note that several <code>Pointer</code> instances may point to the same <code>Node</code> instance. </p>
<p>I use this class to build up very large graphs with millions of instances, and this works fine. The problem comes when the graph is to be deleted. With the default destructor implementation this results in a stack overflow, since in the destructor of the root node, the destructors of the children are called and in the children's destructors, the destructors of the children of the children are called and so on.</p>
<p>I solved this by implementing a destructor for the <code>NodeDerived</code> class above that avoids the recursive call by using a stack instead. This works, but is still very slow, and I am looking for a way to speed this up. Is it possible to somehow avoid declaring the destructor <code>virtual</code> without causing a memory leak?</p>
