<p>So making a second one means changing the <em>modal</em> to something else in the following places:</p>
<p>var $modal = $('#<strong>modal</strong>')</p>
<p>.attr('id', '<strong>modal</strong>')</p>
<p>$('<strong>#modal-trigger</strong>').click(function(evt) {</p>
<p>$('body').append(<strong>$modal</strong>);</p>
<p><strong>$modal</strong>.remove();</p>
<p>Is there a way to shorten this, so I do not have to keep adding the full code to achieve this effect?</p>

5,670,007 | 5,670,008 | using $this or parent:: to call inherited methods? | <p>Not really a problem, more like curiosity on my part but as an example, say I have a php class:</p>
<pre><code>class baseTestMain
{
protected function testFunction()
{
echo 'baseTestMain says hi';
}
}
</code></pre>
<p>and another class that extends from that class above:</p>
<pre><code>class aSubClass extends baseTestMain
{
public function doingSomething()
{
parent::testFunction();
//someextrastuffhere
}
}
</code></pre>
<p>Normally, when I want to call a parent method when defining a new method in the subclass I would do the above - <code>parent::methodnamehere()</code> however instead of <code>parent::</code> you can also use <code>$this->methodname()</code> and the operation would be the same.</p>
<pre><code>class aSubClass extends baseTestMain
{
public function doingSomething()
{
$this->testFunction();
//someextrastuffhere
}
}
</code></pre>
<p>So what I'm asking is, should I use <code>parent::testFunction();</code> or use <code>$this->testFunction();</code> ? or is there a difference to it that I've missed? If not, whats your preference or the preferred method?</p>
<p>Do note that I am not overriding or extending that function in the subclass, essentially the implementation is carried over from the parent.</p>

1,777,694 | 1,777,695 | jquery to change image src of current row only | <p>I have a table with multiple rows that all have the same class. When an image is clicked, there's a db call then returning json. I have everything working correctly but when I click the image, ALL in the table change. I would only like the current row image to be affected.</p>
<p>Example Table:</p>
<pre><code><tr class="changerow">
<td><a href="" class="hide"><img src="image.png" class="someimage" /></a></td>
<td><a href="" class="hide"><img src="image.png" class="someimage" /></a></td>

</tr>

<p>Jquery:</p>
<pre><code>$('.hide').live('click',function(){
var row=$(this);
$('.someimage').attr("src","newimage.png");
});
</code></pre>
<p>So, I know I need to somehow identify the current row and create the variable "row". Not exactly sure how to do this. Was thinking using row.parents('.changerow') or something like that. Help please :) Thanks!</p>

5,845,422 | 5,845,423 | reuse function logic in a const expression | <p>I think my question is, is there anyway to emulate the behaviour that we'll gain from C++0x's <code>constexpr</code> keyword with the current C++ standard (that is if I understand what <code>constexpr</code> is supposed to do correctly).</p>
<p>To be more clear, there are times when it is useful to calculate a value at compile time but it is also useful to be able to calculate it at runtime too, for e.g. if we want to calculate powers, we could use the code below.</p>
<pre><code>template<int X, unsigned int Y>
struct xPowerY_const {
static const int value = X*xPowerY_const<X,Y-1>::value;
};
template<int X>
struct xPowerY_const<X, 1> {
static const int value = X;
};
int xPowerY(int x, unsigned int y) {
return (y==1) ? x : x*xPowerY(x,y-1);
}
</code></pre>
<p>This is a simple example but in more complicated cases being able to reuse the code would be helpful. Even if, for runtime performance, the recursive nature of the function is suboptimal and a better algorithm could be devised it would be useful for testing the logic if the templated version could be expressed in a function, as I can't see a reasonable method of testing the validity of the constant template method in a wide range of cases (although perhaps there is one and i just can't see it, and perhaps that's another question).</p>
<p>Thanks.</p>
<p><strong>Edit</strong>
Forgot to mention, I don't want to <code>#define</code></p>
<p><strong>Edit2</strong> Also my code above is wrong, it doesn't deal with x^0, but that doesn't affect the question.</p>

704,059 | 704,060 | Question about focus and activites on Android | <p>I have a chat application here that uses a handler and a runnable to frequently poll for updates. On receiving an update as HTML, it adds this content to the TextView in the main activity.</p>
<p>Now, I've noticed that when the activity loses focus and I use other applications/view the home screen, the runnable keeps going on and when I re-open the application, I see the TextView with the updated content.</p>
<p>Is this considered unsafe and should I build a service to do this, or is it fine to modify the UI when it's unfocused like that?</p>

<pre><code>struct structData
{
char m_chType; // variable to indicate the data type - long, float or string
long m_lData; // variable to hold long value
float m_fData; // variable to hold float value

</code></pre>
<p>I am currently sending an array of structData over the message queue. </p>

<p>The problem here is that only one variable in the structure is useful at a time, the other two are useless. The message queue is therefore unneccessarily overloaded.
I can't use unions because the datatype and the value are required.
I tried using templates, but it doesn't solve the problem.I can only send an array of structures of one datatype at a time.</p>
