As a developer on the receiving end of Flash files, I've gotten used to dealing with FlashVars as a way to configure a Flash application. I've wondered how I'd do this in Flex though. Joao Fernandes sent me some sample code and showed me the way.

Consider this simple Flex page:

<?xml version="1.0" encoding="utf-8" ?> <mx:Application xmlns:mx="" layout="absolute" xmlns:comp="components.*">
import mx.controls.Alert;

private function test():void {' '+this.parameters.flashvar2, "Flashvars");	

&lt;mx:Button id="btnTest" label="Test" click="test()" /&gt;


Note the this.parameters? This lets me get access to the flashvars. I named them flashvar1 and flashvar2 which isn't very creative. Obviously it could be any name. To pass the variables in you can simply edit the generated HTML.

"flashvars",'flashvar1=ray&flashvar2=camden&historyUrl=history.htm%3F&lconid=' + lc_id + '',

Don't forget that each Flex project has an HTML template. It would make sense to edit the template so you don't have to re-edit the generated HTML after each build.

This should help take care of the "root CFC" issue I mentioned a week or so ago.
