Not sure if this is helpful to anybody, but thought I’d throw it out there. The following basic example loads some random variables from an external text file and displays the events which were dispatched in a DataGrid control, as well as the loaded name/value pairs.

By On July 27, 2007 · 15 Comments

In the previous post we looked at how to load an XML document in at compile-time and have it embedded in our Flex application.

By On July 26, 2007 · 33 Comments

OK, hopefully this example is a bit more interesting than a few of my previous ones. Today’s handy tip comes in the form of loading and embedding an XML file in our Flex application at compile-time (as opposed to dynamically loading at run-time, which we’ll save for a future example), and displaying that information in [...]
