See the below example to know your system resolution

package druva.vini {
  import flash.system.Capabilities;
  import flash.net.*;
  import flash.display.*;
  import flash.text.TextField;

  public class SystemCap extends Sprite {

    public function SystemCap(){
        var resX:int = flash.system.Capabilities.screenResolutionX;
        var resY:int = flash.system.Capabilities.screenResolutionY;

		var field:TextField = new TextField();
			field.border = true;
			field.text = 'resX ' + resX + '\nresY ' + resY;
			field.background = true;

The below code shows how to format currency string using Action Script

import druva.StringUtils;

trace(StringUtils.br2nl('This is <br>my<br>sample<br>text'));

Have a look at the class

package druva {
	import flash.display.Sprite;

	public class StringUtils extends Sprite {
		public function StringUtils() {
		}

		public static function br2nl(str:String):String {
       		return str.split( "<br>" ).join( '\n' );
		}		

	}
}

This examples shows how to have vertical slider

import fl.controls.Slider;
import fl.controls.SliderDirection;

var slider:Slider = new Slider();
slider.direction = SliderDirection.VERTICAL;
slider.tickInterval = 1;
slider.move(20, 20);
slider.height = 90
addChild(slider);

for (var i:int = 0, n:int = 10; i < 10; i++, n--) {
	trace("i is " + i);
	trace("n is " + n);
}

var user:Object = new Object();
user.name= 'druva';
user.pass = "dontexpectit";
user.age = 25;

for each (var element in user) {
	trace(element.toString());
}

var sum:Number=10;
do {
sum+=5;
trace(sum + ” – surpassed 10″);
} while (sum < 50);

The below code shows how to fadeIn a MovieClip

function fadeIn (mc:MovieClip, speed:Number):Void  {
    mc.onEnterFrame = function() {
        if (mc._alpha<100) {
            mc._alpha += speed;
        } else {
            delete mc.onEnterFrame;
        }
    };
};

fadeIn(myMovieClipInstance, 5);

You can also declare the same as protoType

MovieClip.prototype.fadeIn = function(speed:Number):Void  {
    this.onEnterFrame = function() {
        if (this._alpha<1000) {
            this._alpha += speed;
        } else {
            delete this.onEnterFrame;
        }
    };
};

myMovieClipInstance.clip_mc.fadeIn(5);
