Flash Builder 4: Network Monitor and new debugger options from Mihai Corlan on Vimeo.

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&gt>
</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>

The Real-Time Messaging Protocol (RTMP) was designed for high-performance transmission of audio, video, and data between Adobe Flash Platform technologies, including Adobe Flash Player and Adobe AIR. RTMP is now available as an open specification to create products and technology that enable delivery of video, audio, and data in the open AMF, SWF, FLV, and F4V formats compatible with Adobe Flash Player.

View Adobe RTMP Specification License

Mihai Corlan:

“We announced earlier this year that we’d open up the specifications for Real-Time Messaging Protocol (RTMP is the protocol used by Flash Media Server and LiveCycle Data Services). We did it today, and you can read the details here.

Basically you can download the specifications and start implementing your own servers that make use of this highly efficient protocol for sending data between Adobe Flash Player or Adobe AIR apps and various servers.

It is worth noting that we didn’t open up anything related to RTMPe – Adobe’s implementation to secure the content. While you as a developer don’t have access to our implementation, you are free to implement your own secure implementation on top of RTMP.”
