<p>The problem is, the alert 'go to page 1' only comes up once in Internet Explorer 7 and 8. The second time I change a dropdown there is nothing. (when i place an alert in the 'change' function, it will pop up every time)</p>

<pre><code>$('.pageLink').live('click', function(event){
event.preventDefault();
// read quickfilter here
// request the results and do some magic animations to display them
alert('go to page 1');

<pre><code>require_once("../config.php");
</code></pre>
<p>or even</p>
<pre><code>require_once("../../config.php");

<p>But I never get it right the first time. I can't figure out what php is going to consider to be the current working directory when reading one of these files. It is apparently not the directory where the file containing the require_once() call is made because I can have two files in the same directory that have different paths for the config.php.</p>
<p>How I have a situation where one path is correct for refreshing the page but an ajax can that updates part of the page requires a different path to the config.php in the require_once() statement;</p>
<p>What's the secret? From where is that path evaluated?</p>

<p>team 'b' = 10</p>

<p>then you swap the values in the hashmap which will look like...</p>

<p>team 'a' = 10</p>
<p>team 'b' = 23</p>

First, it multiplies all the arguments and stores the result in a variable (result1), then it adds up all the arguments and stores the result in another variable (result2). Finally it returns the difference between result1 and result2 (result1 – result2). If you use overloading, you will end up with three functions with the same name.

<p>We created a test app with a stripped down manifest and compiled it with the Android 1.5 SDK. Even this basic app is filtered out. We tried contacting Android Market support five days ago but Google makes it pretty clear they don't want to provide support to developers and say that it's unlikely we'll get a reply.</p>

5,343,319 | 5,343,320 | Templated Vector and Colour Maths library (Specialisation) | <p>I have created a maths library that operates via templates, it allows the user to specify the size and type of the array within a class which is then used to create a maths vector of any dimension up to four. As soon as I went to create a colour class, it struck me how similar the vector and colour class are. Is there anyway in which I could reduce code reuse and use some form of inheritance or specialisation to separate:</p>
<ol>
<li>Specific functionality (ie vector3 does not have a setXYZW() function, instead only a setXYZ()) to the dimension of which it can only be used in.</li>
<li>Colour class and vector class can both (in terms of array data member) be of size ranging from 1 to 4 and the both share the same operators, but differ in their use in some circumstances such as a multiply vector differs from a multiply colour.</li>
</ol>
<p>My knowledge of templates is not that good, so I would very much appreciate if anyone can show me the best solution to such a situation?</p>
<p><pre>
<code>template < std::size_t N = 3, typename T = float >
class Vector
{
typedef T Degree, Radian;
private:
T m_vecEntry[N];

<p>I have been trawling the internet for hours now trying various different hacks to try to stop IE7 from ballsing up PNGs.

}
});
</script>
</code></pre>
<p>This function is found near the footer section of the HTML although in some places it outputs on the head section. Someone suggested me to load this jQuery inside $(window).load() function. The reason is that $(document).ready event is fired when DOM is loaded, so it’s fired when the document structure is ready, but before images are loaded.</p>
<p>$(window).load() event is fired after whole content is loaded. So .position() method might not calculate correct position when it’s fired to early (before images are loaded). </p>
<p>If this true, how to revise the above load in $(window).load(). Thanks.</p>
<p><strong>UPDATE</strong>: I have changed from:</p>
<pre><code>jQuery( document ).ready( function( $ ) {
