Actionscript 3.0 :: Preloading External Loaded Swfs?

this is the code i'm using to load external swf files....

Code: Select allstop();
/////////////////////////Music
var s:Sound = new Sound();
s.load(new URLRequest("rainbow.mp3"));

[code].....

but how do i implement this code for preloading ever swf?

Code: Select allloader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loadProgress);loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);function loadProgress(event:ProgressEvent):void {var percentLoaded:Number = event.bytesLoaded/event.bytesTotal;percentLoaded = Math.round(percentLoaded * 100); trace("Loading: "+percentLoaded+"%");}function loadComplete(event:Event):void {   trace("Complete");}

all i want is a simple text with % preloader on all the loaded swfs?
