<pre><code>private void listBox1_SelectedIndexChanged(object sender, EventArgs e)

{
label4.Text = listBox1.SelectedItem.ToString();
string startTag = "Url: ";

string g = label4.Text.Substring(start, index - start);
label4.Text = g;
mainUrl = g;
}
}
</code></pre>
<p>I want that after I selected an index(item) in the <code>ListBox</code> and I make now right click with the mouse on this index it will do something. But if I will make mouse right click button on any other area on the <code>ListBox</code> or the Form it won't do anything. Only if the mouse is on the selected index. </p>
<p>What I need to do is that the user will be able to remove/delete an item from the <code>ListBox</code>.
I just don't know what is the best logic of how to do it when the user click the right mouse button.</p>
<p>Show I make it when the user first selected an item and only if the mouse is above/on this selected item ? Show I do it that if the user clicked mouse right button on any item it will select it automatic and do something ? </p>
<p>Im not sure wich way is better and logic and how to do it.</p>

<p>I've used jsbeautifier.org for years, and I've seen the modified version at <a href="http://jsfiddle.net/RabTN/29/" rel="nofollow">http://jsfiddle.net/RabTN/29/</a> which does comma first (though other bits of jsbeautifier.org's beautifier are a bit funky there...).

$(this).parents('tr:eq(1)').prevAll('[id^=foo_]:first').find('.TrackList_LineBreak').text();

3,375,282 | 3,375,283 | jQuery: Use variables within selector | <p>Mind you, I'm not a jQuery guru and just still learning.</p>
<p>I have this looong function:</p>
<p><code>$('.client1 > *:first-of-type, .client2 > *:first-of-type, .client3 > *:first-of-type, .client4 > *:first-of-type, .client5 > *:first-of-type').append('<span class="jsi"/>');</code></p>
<p>It does work, yes, but I know it's not efficient and not easily scalable because every time I have to add a new 'client' I have to add it to the selector list.</p>
<p>So I know I could use (a) variable(s) for the <code>> *:first-of-type</code> part, and maybe an "array" (I don't know if I'm saying that right) for the <code>.clientX</code> part.</p>
<p>This is honestly a bit over my head.</p>
<p>This is what I've tried but of course doesn't work:</p>
<pre><code>var fot = "> *:first-of-type";
$('.client1' + fot, '.client2' + fot, '.client3' + fot, '.client4' + fot, '.client5' + fot).append('<span class="jsi"/>');
</code></pre>
<p>What happens is not only I would like to not have to repeat myself but be able to scale this more efficiently as new clients need to be added to the function.</p>
<p>Any help on this is greatly appreciated.</p>

4,116,371 | 4,116,372 | Understanding Global & Local Scope in Javascript | <p>I've been learning Javascript using <a href="http://www.packtpub.com/object-oriented-javascript/book" rel="nofollow">Object-Oriented JavaScript by Stoyan Stefanov</a></p>
<p>He offers an example comparing global and local scope:</p>
<pre><code>var a = 123;
function f() {
alert(a);
var a = 1;
alert(a);
}
f();
</code></pre>
<p>Looking at this example, I expected the first alert to be '123' and the second alert to be '1'. Lo and behold, Stoyan says:</p>
<blockquote>
<p>You might expect that the first alert() will display 123 (the value of
the global variable a) and the second will display 1 (the local a).
This is not the case. The first alert will show “undefined”. This is
because inside the function the local scope is more important than the
global scope. So a local variable overwrites any global variable with
the same name. At the time of the first alert() a was not yet defined
(hence the value undefined) but it still existed in the local space.</p>
</blockquote>
<p>The explanation was not clear to me, how can the local variable overwrite the global variable in the first alert? Any other/different explanations would be appreciated.</p>

450,520 | 450,521 | How do I make an instance of an object accessible to multiple swing forms? Java | <p>I'm making a text based RPG to help me learn Java. So I have a bunch of different classes that make swing forms right now and each of which will lead to one another. However, in one form I actually create the instance of the object called Player, where I will set the stats (strength, agility, level, etc.) based on the choices the user makes.</p>
<p>However, I can only access that object in that class/window and I can't call it for manipulate that object anywhere else in the application.</p>
<p>How do I make it globally accessible?</p>
<p><strong>Edit</strong><br>
I should have phrased this better. Let's say I have a class called PlayerCreation and in PlayerCreation I make an object by calling the Player class Player p1 = new Player(); Now I move out of that class completely and go to another form called PlayerStats and I want to call p1.getStrength(); but since p1 was in PlayerCreation class, I can't get it.</p>

322,714 | 322,715 | jQuery - Display the value of a textbox and input the value to another | <p>Basically I want to get the value of a textbox which is to select a date and output the value that is selected to another textbox.</p>
<p>These textboxes are on the same page (different steps of the same page) and the document is loaded when the page is ready on click of the next step, I've tried using:</p>
<pre><code>$('#TextBox1').val($('#TextBox2').val());
</code></pre>
<p>But this doesn't seem to be working. What is it I am doing wrong? </p>
<p><em>EDIT</em></p>
<p>Here is some of the HTML:</p>
<p>I want to get the value the user has inputted for the Date for example:</p>
<pre><code><label for="txt-outbound-date" class="left p-input-label" >Date: </label>
<input type="text" id="txt-outbound-date" name="txt-outbound-date" class="input-txt-sml left required" />
</code></pre>
<p>And output the value they select in the following textbox:</p>
<pre><code><input type="text" class="input-txt-med required left" id="txt-selected-date" name="txt-selected-date" />
</code></pre>
<p>This is for a summary page which will display all the results the user has input, as I've said, this is all on one page and the .js file is loaded each time the user clicks 'Next' so I would have thought the following would work:</p>
<pre><code>$('#txt-outbound-date').val($('#txt-selected-date').val());
</code></pre>
<p>Any suggestions?</p>

5,908,982 | 5,908,983 | Stopping an app generated log from running | <p>I am new to android programming and development. I am working on app that auto generates a log file and attaches it to an email. The problem I am having is making the log stop running. It generates the .text file to the sd card to attach to the email, but the log keeps running and never stops. The only way I am able to attach the log is to power cycle the phone and stop the log from running. I have looked at the timer class, but I am not sure if that is what I need or if there is another way to do this. Here is the beginning and end, I left out the intents in the middle due to just being email intents.</p>

1,677,045 | 1,677,046 | Dynamic configuration object based on __setattr__ and _getattr__ | <p>I tried to create dynamic object to validate my config in fly and present result as object. I tried to achieve this by creating such class:</p>
<pre><code>class SubConfig(object):

self.__config = config
self.__values = {}
self.__key_types = key_types
def __getattr__(self, item):
if item in self.__key_types:
return self.__values[item] or None
else:
raise ValueError("No such item to get from config")
def __setattr__(self, item, value):
if self.__config._blocked:
raise ValueError("Can't change values after service has started")
if item in self.__key_types:
if type(value) in self.__key_types[item]:
self.__values[item] = value
else:
raise ValueError("Can't assing value in different type then declared!")
else:
raise ValueError("No such item to set in config")
</code></pre>
<p>SubConfig is wrapper for section in config file. Config has switch to kill possibility to change values after program started (you can change values only on initialization).</p>
<p>The problem is when I setting any value it is getting in infinity loop in getattr. As I read <code>__getattr__</code> shouldn't behave like that (first take existing attr, then call <code>__getattr__</code>). I was comparing my code with available examples but I can't get a thing.</p>
<p>I noticed that all problems are generated my constructor.</p>

no JSONP calls.</p>
<p>It looks like if I added a global event <code>'beforeunload'</code> to window object. and it is stored in window[expando]. However if I added some events to other DOM object such as <code>button</code>, and they are stored in jQuery.cache.
here is the screen shot form jQuery.cache and window[jQuery1800xxxxxxxxxxxxxxxx]
I am not sure why the guid for that 2 click events are both 8. those 2 click events are binded to 2 buttons. and click event handler are the same function.</p>
