Thank you all for your ideas and suggestions so far. Keep 'em coming! | | | | | What is the XML DOM? | | The XML DOM provides a way for browsers with XML parsers to read and manipulate code. By itself, XML does not actually say much. It is a collection of information stored in a file that has no meaning. The DOM structure is what organizes the code so that languages, like JavaScript, can read and understand it. It is the standard model that allows the display of XML data on a Web page. | | | | | Exception Handling in C# | | When something goes wrong in a C# program, it often generates an exception. It could be something like trying to open a file that's already opened by something else, an invalid argument to a method, a reference that is null or a dozen other reasons. Despite that in most of your code you won't have to worry about exceptions. This tutorial explains how you can deal with them when you need to. | | | | | Java: Using the Arrays Class | | To make life a little easier for developers working with arrays, the Java API contains a utility class called Arrays. The Arrays class can be used to display the contents of an array, compare two arrays, sort an array, fill the elements of an array, search an array and copy an array. | | | | | PHP: Counting Outbound Clicks | | This is a simple little bit of code that can be used to count links going off of your site. It was originally written to count click-throughs for a 'Top Sites' program, but could be useful for any site that needs to count how many outgoing links are clicked, and to what pages. | | | | | | |  | You are receiving this newsletter because you subscribed to the About Programming newsletter.
