Flex talking to Flash

Here's another good refresher on getting a Flex app synched up with Flash swf resources, this time at giantflyingsaucer.com. I'll post a link to a tutorial on Flex with Flash-compiled swcs as soon as I come across one. Any favorites out there?

Accessing swf vars from Flex

Ever need your memory jogged on the topic of putting swf vars into your Flex app? Here's just the thing for that:

Flash cs3 as3 file "click.swf"

ActionScript Code:

click_mc.addEventListener(MouseEvent.CLICK, reportClick);
var output:String = new String();

function reportClick(evt:MouseEvent):void
  {
      for(var i:int = 0; i<5; i++) {
          output += "I have been clicked. i = " + i + "\n";
      }
  }

MXML Flex 2.0

ActionScript Code:

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">

<mx:Script>
  <![CDATA[
      private function updateTextField():void
      {
          output_txt.text += swf.content["output"];
      }
  ]]>
</mx:Script>

  <mx:SWFLoader x="10" y="10" source="click.swf" scaleContent="false" id="swf" click="updateTextField()"/>

  <mx:TextArea x="10" y="518" width="550" height="211" id="output_txt"/>

</mx:Application>

Made for Flex 2 but perfectly applicable to 3, 4 and perhaps beyond... Thanks to the forums at actionscript.org for this one.
