This code show how to create falling hearts with flash cs4

you can also use the code for cs3
create a movieclip with a heart in your library

package {

	import flash.display.MovieClip;
	import flash.events.*;

	public class fallingheart extends MovieClip {
		public function fallingheart() {
			for (var i = 0; i < 30; i ++) {
				var h:heart = new heart();
				h.x=Math.round(Math.random()*stage.stageWidth);
				h.y=Math.round(Math.random()*stage.stageHeight);
				h.scaleX = h.scaleY = .4+ ((Math.random()*1)/2);
				h.swing = 15 + (Math.random()*15);
				h.n=Math.random()*2;
				h.speed = 1 + (Math.random()*4);

				addChild(h);
				h.addEventListener(Event.ENTER_FRAME, onEnterLoop);
				//h.onEnterFrame = fall;
			}
		}

		//--  you can also use timer to call this
		public function onEnterLoop(e:Event) {
			trace(stage.stageHeight);
			var h:heart=e.currentTarget as heart;
			h.y+=h.speed;
			h.n+=0.25;
			h.rotation=Math.cos(h.n)*h.swing;
			if (h.y>stage.stageHeight) {
				h.x=Math.round(Math.random()*stage.stageWidth);
				h.y=-50;
			}
		}
	}
}

Using URLVariables in Flash or Flex we can send and receive data from server he is the example

This is the PHP Code nested in the server
Create a PHP file and place it in the server

<?php
 $email=$_POST['email'];
 $password=$_POST['password'];

echo "email=".$_POST['email']."&amp;password=".$password;
?>

Here is the code in Flash/Flex

//create URLRequest instace withe the target URL
var request:URLRequest = new URLRequest("http://www.example.com/data.php");

//create instance of the class
var variables:URLVariables = new URLVariables();

variables.email = druva.flash@gmail.com;
variables.password = 'dontexpectit';

//add the data to the URLRequest
request.data = variables;

//Choose a method as POST
request.method = URLRequestMethod.POST;

var loader:URLLoader = new URLLoader();
//Create EventListener
loader.addEventListener(Event.COMPLETE, handleComplete);

//send the request with URLLoader()
loader.load(request);

 function handleComplete(event:Event)  {
var loader:URLLoader = URLLoader(event.target);
var vars:URLVariables = new URLVariables(loader.data);

//Read data for the result
trace("vars.email: "+vars.email);
trace("vars.password: "+vars.password);
 }

This code show how to create snowfall in flash cs4

u can also use the code for cs3

package {

	import flash.display.MovieClip;
	import flash.events.Event;
	import flash.filters.BlurFilter;
	import druva.NumberUtil;
	import flash.utils.Timer;
	import flash.events.*;

	public class snowfall extends MovieClip {

		private var t:Timer;

		public function snowfall():void {
			t=new Timer(80);
			t.addEventListener(TimerEvent.TIMER, createParticle);
			t.start();
		}

		private function createParticle(e:TimerEvent) {

			var mc_particle:MovieClip =new MovieClip();
			mc_particle.graphics.beginFill(0xFFFFFF,1);
			mc_particle.graphics.drawCircle(0, 0, NumberUtil.getRand(3,5));
			mc_particle.graphics.endFill();

			mc_particle.x=NumberUtil.getRand(-60,600);
			mc_particle.wind = (NumberUtil.getRand(0,1) == 1) ?  'left' : 'right';
			mc_particle.filters=[new BlurFilter(10,10,2)];
			mc_particle.addEventListener(Event.ENTER_FRAME, moveParticle);
			addChild(mc_particle);

		}

		function moveParticle(e:Event):void {
			var targ:MovieClip=MovieClip(e.target);

			if (targ.y>400) {
				targ.removeEventListener(Event.ENTER_FRAME,moveParticle);
				removeChild(targ);
				return;
			}

			targ.y += 1;

			if (targ.wind=='left') {
				targ.x += 0.4;
			} else if (targ.wind== 'right') {
				targ.x -= 0.4;

			}

		}

	}
}
