programming flash
1

Hi for all, i wrote the class bellow and when i load class and use this class into my FLA file i receive the message:

[INDENT]Access of undefined property loadProgress
Access of undefined property loadComplete[/INDENT]

I import and use classe like show bellow:

import com.dLibs.openFile;
openFile.addFile(contentLoaded,"Pessoal/wp_lucas001.jpg",2,"easeOutBack");

and here my class:

package com.dLibs {
	
	import flash.display.*;
	import flash.net.*;
	import flash.events.Event;
	import flash.events.ProgressEvent;
	import caurina.transitions.Tweener;
	
	public class openFile {
		
		private var _contLoadClip:MovieClip;
		private var loader:Loader;
		private var request:URLRequest;
		
		public var contClip:MovieClip;
		public var transTime:Number;
		public var transMode:String;
		
		public function openFile() {
			trace("public funcion 'n static");
		};
		
		public static function addFile(contClip:MovieClip, file:String, transTime:uint = 1, transMode:String =  "easeOutElastic"):void
		{			
			var request:URLRequest = new URLRequest(file);
			var loader:Loader = new Loader();
			loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loadProgress);
			loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
			loader.load(request);
		};
		
		private function loadComplete(event:Event):void 
		{
			contClip.addChild(loader);
			contClip.alpha = 0;
			Tweener.addTween(contClip, { alpha : 1, time : transTime, transition : transMode });
		};
			
		private function loadProgress(event:ProgressEvent):void 
		{
			var percentLoaded:Number = event.bytesLoaded/event.bytesTotal;
			percentLoaded = Math.round(percentLoaded * 100);
			// trace("Loading: "+percentLoaded+"%");
		};
	};
};

if anyone know about this error, please help-me.
I’m waiting and Tks for all in advance.
