The code below works perfect for binding actual urls grabbed from the net. My issue is that it does not work for *.aspx urls that generate an image. If I go to the *.aspx page "~/UserPages/Photo/GetThumbnail.aspx?id=7", an image shows up just fine. However it does not work for the datalist. Any ideas why and how I can solve this issue. T...

Hey everyone, When implementing a Matrix construct using arrays, which would be more efficient? Using a 1D array, or an array of arrays (2D)? I would think a 2D is more efficient as you already have the X and Y coordinates of an element, where in a 1D implementation you have to calculate the index. Any thoughts? Thank you Edit: it ...

Hi, I need a way of sorting a string I have in PHP, the string is formatted like the one below, but is much bigger. { 1, 3, 1, 2, }, { 2, 3, 2, 1, }, { 3, 3, 2, 2, }, { 1, 2, 3, 1, }, What I would need it to do is turn each set of numbers that is in the brackets into an array. So in this case there would be four arrays with four value...

I've got an XML file storing an array of shorts in my resources. I need to assign this array, but Android API only provides a way to get array of ints (getResources.getIntArray()). I've ended up getting an array of ints and converting it to array of shorts later, but that's hardly ideal. Is there a way to get an array of shorts from And...
I want to output the elements of an array in a specific format in Perl. @myArray = ("A", "B", "C"); $text = something; Something should be the string '"A" "B" "C"' (each element enclosed in double quotes). However, if @myArray is empty, then $text should be too. I thought of using join(), such as $text = "\"" . join("\" \"", @myArra...

In every other programming language I use on a regular basis, it is simple to operate on the return value of a function without declaring a new variable to hold the function result. In PHP, however, this does not appear to be so simple: <?php function foobar(){ return preg_split('/\s+/', 'zero one two three four five'); } // can ...
$genreList; function directorGen($array) { foreach($array as $value) { $genreList[] = $value; } } //later.. directorGen($title->genres()); This code results in a NULL array. If I replace $genreList[] = $value with echo $value everything prints out like expected. Any ideas? ...
I seem to remember that in PHP there is a way to pass an array as a list of arguments for a function, dereferencing the array into the standard func($arg1, $arg2) manner. But now I'm lost on how to do it. I recall the manner of passing by reference, how to "glob" incoming parameters ... but not how to de-list the array into a list of a...
