Load Movie() in AS3

var swfToLoad: String = "mySwf.swf";
var loader: Loader = new Loader();
loader.load(new URLRequest(swfToLoad));
addChild(loader);

var myLoader:Loader = new Loader();

myLoader.load(new URLRequest("load.swf"));

------------------------------------------------------------------------------------------------

Load Movie using BUTTONS and Progress BAR

import fl.controls.ProgressBar;

import fl.controls.Button;

var my_loader:Loader = new Loader();

var my_btn:Button = new Button();

my_btn.label = "Load Image";

my_btn.x = 100;

my_btn.y = 200;

addChild (my_btn);

var my_pb:ProgressBar = new ProgressBar();

my_pb.source = my_loader.contentLoaderInfo;

my_pb.x = 100;

my_pb.y = 200;

my_btn.addEventListener(MouseEvent.CLICK, startLoading);

function startLoading(e:MouseEvent):void{

my_loader.load(new URLRequest("myPhoto.jpg"));

addChild(my_pb);

removeChild(my_btn);

my_btn=null;

}

my_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, finishLoading);

function finishLoading(e:Event):void{

addChild(my_loader);

removeChild(my_pb);

my_pb = null;

}

Add mouse click event to SimpleButton

package {
  import flash.display.*;
  import flash.events.*;

  public class SimpleButtonDemo extends Sprite {
   public function SimpleButtonDemo( ) {
   var button:SimpleButton = new SimpleButton( );
   button.x = 20;
   button.y = 20;

   button.upState = createCircle( 0x00FF00, 15 );
   button.overState = createCircle( 0xFFFFFF, 16 );
   button.downState = createCircle( 0xCCCCCC, 15 );

   button.hitTestState = createCircle( 0x000000, 50 );

   button.addEventListener( MouseEvent.CLICK, handleClick );

   addChild( button );
   }

   private function createCircle( color:uint, radius:Number ):Shape {
   var circle:Shape = new Shape( );
   circle.graphics.lineStyle( 1, 0x000000 );
   circle.graphics.beginFill( color );
   circle.graphics.drawCircle( 0, 0, radius );
   circle.graphics.endFill( );
   return circle;
   }

   private function handleClick( event:MouseEvent ):void {
   trace( "Mouse clicked on the button" );
   }
  }
}

--------------------------------------------------------------------

Load and Save in AS3

var buttonShape:Shape = new Shape();
buttonShape.graphics.beginFill(0x336699);
buttonShape.graphics.drawCircle(50, 50, 25);
var button = new SimpleButton(buttonShape,
buttonShape, buttonShape, buttonShape);
addChild(button);

var fileRef:FileReference= new FileReference();
button.addEventListener(MouseEvent.CLICK, onButtonClick);

function onButtonClick(e:MouseEvent):void {
fileRef.browse([new FileFilter("Text", "*.jpg;*.gif;*.png")]);
fileRef.addEventListener(Event.SELECT, onFileSelected);
}

function onFileSelected(e:Event):void {
fileRef.addEventListener(Event.COMPLETE, onFileLoaded);
fileRef.load();
}

function onFileLoaded(e:Event):void {
var loader:Loader = new Loader();
loader.loadBytes(e.target.data);
addChild(loader);
}

var MyTextField:TextField = new TextField();
var MyButtonField:TextField = new TextField();
var MyFile:FileReference = new FileReference();

MyTextField.border = true;
MyTextField.type = TextFieldType.INPUT;
MyTextField.y=100

MyButtonField.background = true;
MyButtonField.backgroundColor = 0x339933;
MyButtonField.x = 150;
MyButtonField.height = 20;
MyButtonField.text = "Click here to save";

addChild(MyTextField);
addChild(MyButtonField);
MyButtonField.addEventListener(MouseEvent.CLICK, clickhandler);

function clickhandler(e:MouseEvent): void {
MyFile.save(MyTextField.text);
}

------------------------------------------------------------------

Switch Case for Buttons

but1.addEventListener(MouseEvent.CLICK, clickHandler);
but2.addEventListener(MouseEvent.CLICK, clickHandler);
but3.addEventListener(MouseEvent.CLICK, clickHandler);

function clickHandler(event:MouseEvent):void
{

switch (event.currentTarget.name)
{
case "but1" :
trace("you chose a red Papa Smurf");
break;
case "but2" :
trace("you chose a green Papa Smurf");
break;
case "but3" :
trace("you chose a blue Papa Smurf");
break;

}
}
