We made a little test to see the flex performance on parsing an large array.
Here is the experiment:
var size:Number = 10000000;
var arr:Array = [];
for (var i:int=0; i
var time:Number, o:Object;
// for()
time = getTimer();
for (i=0; i=0; i--) { arr[i]; }
trace("for reversed test: "+(getTimer()-time)+"ms");
// for..in
time = getTimer();
for each(o in arr) { o; }
trace("for each test: "+(getTimer()-time)+"ms");And here are the results:
for test: 124ms
for reversed test: 110ms
for each test: 261ms
We wish you to use this results wisely !

If you want to create a localized application you may find yourself in a strange situation when you did all the steps like in the book, but you continue to receive the “Unable to open locale xx_XX” error messages.
To simulate a fix on this issue we will take the example of adding French to your app.
Basic steps:
- The first step is to create a fr_FR folder under the /locale/ one exactly like in the Flex documentation and then add the translated bundle.properties file.
- The second step is to add the compiler options: -locale en_US,fr_FR
Extra steps you need to make in order to get rid of the ugly “unable to open locale” error message:
1. goto the following path :
<flex-install-folder>/sdks/<current-sdk-folder>/bin/
for windows it’s: C:\Program Files\Adobe\Flex Builder 3\sdks\3.2.0\bin\
2. Execute the following command:
> copylocale.exe en_US fr_FR
That’s all, hope we helped you!

Hello,
If you are trying to access the stage of your application right when your app is completed then you’re doing something wrong.
BAD CODE Most of the cases programmers make the following mistake:
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()">
<mx:Script>
<![CDATA[
import flash.display.StageDisplayState;
private function init():void
{
var s:Stage = this.stage; //<<-- this.stage == null...why??
s.scaleMode = StageScaleMode.EXACT_FIT;
}
]]>
</mx:Script>
</mx:WindowedApplication>
GOOD CODE : The correct approach is the following:
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication
xmlns:mx="http://www.adobe.com/2006/mxml"
creationComplete="init()">
<mx:Script>
<![CDATA[
import flash.display.StageDisplayState;
private function init():void
{
this.systemManager.stage.scaleMode = StageScaleMode.EXACT_FIT;
}
]]>
</mx:Script>
</mx:WindowedApplication>
Hope we helped you with this issue we also had in our beginning as Flex Devlopers
