The code also works with flash cs3

import fl.controls.TextInput;
import fl.controls.Label;

var myLabel:Label = new Label();
myLabel.text = "Caret Index Word";
myLabel.x = 5;
myLabel.y = 0;
addChild(myLabel);

var textInput:TextInput = new TextInput();
textInput.x = 100;
textInput.y = 10;
addChild(textInput);

var t:Timer = new Timer(100);
t.addEventListener(TimerEvent.TIMER, caretindex);

function caretindex(e:TimerEvent):void {
	var caretIndex:Number = textfield.getCharIndexAtPoint(textfield.mouseX, textfield.mouseY)
	if(caretIndex == -1) {
		return;
	}
	var str:String = textfield.text;
	var words:Array = str.split(' ');
	var n:Number = 0;
	while(n<=words.length){
		var subset:Array = words.slice(0, n);
		var sliceString:String = subset.join(' ');
		if(sliceString.length>caretIndex) {
			textInput.text = String(subset[n-1]);
			break
		}
		n++;
	}
}
t.start();

This code shows how to use display objects like GradientType, InterpolationMethod, SpreadMethod and scale9Grid.

var rect:Shape = new Shape();
rect.graphics.lineStyle(10, 0x000000);
var matrix:Matrix = new Matrix();
matrix.createGradientBox(15, 15, Math.PI, 10, 10);
rect.graphics.beginGradientFill(GradientType.RADIAL,[0x000000, 0x76A3DA], [100, 100],
            [0, 0xFF],matrix,SpreadMethod.REFLECT,InterpolationMethod.RGB,0.9);

rect.graphics.drawRect(0, 0, 90, 90);

var grid:Rectangle = new Rectangle(20, 20, 50, 50);
rect.scale9Grid = grid ;

addChild(rect);

var timer:Timer = new Timer(80);
timer.start();
timer.addEventListener(TimerEvent.TIMER, imageResize);

var scale:Number = 1.01;

function imageResize(event:TimerEvent):void {
    rect.scaleX *= scale;
    rect.scaleY *= scale;

    if (rect.scaleX > 2.0) {
        scale = 0.99;
    }
    if (rect.scaleX < 1.0) {
        scale = 1.01;
    }
}

var springX:Number=0;
var springY:Number=0;
var spring:Number=.95;
var radius:Number=300;

ball.addEventListener(Event.ENTER_FRAME, Event_ENTER_FRAME);
ball.x=ball.y=Math.random()*300;
stage.addEventListener(MouseEvent.MOUSE_DOWN, onClick);

function onClick(event:Event):void {
	ball.x=mouseX;
	ball.y=mouseY;
}

function Event_ENTER_FRAME(event:Event):void {
	var ax:Number=0;
	var ay:Number=0;
	ball.x+= (springX += ((radius - (2 * ball.x)) * .1));
	ball.y+= (springY += ((radius - (2 * ball.y)) * .1))
	springX*=spring;
	springY*=spring;
}

This code show how to use TextElement, TextBlock, FontDescription, TextBlock, TextLine

package druva{
import flash.display.Sprite;
import flash.text.engine.*;

public class TextTest extends Sprite {

public function TextTest() {

for (var j:int=0; j<=10; j++) {
var myString:String="Druva";
var myFormat:ElementFormat = new ElementFormat();

var myFontDesc:FontDescription=new FontDescription('Georgia','normal','italic','device');
myFormat.fontSize=2+2*j;
myFormat.fontDescription=myFontDesc;
myFormat.color = Math.random() * 0xFFFFEE;

var textElement:TextElement=new TextElement(myString, myFormat);
var textBlock:TextBlock = new TextBlock();
textBlock.content=textElement;

var myTextLine:TextLine=textBlock.createTextLine(null,300);

myTextLine.x = 30+(3*(j*(j+1)/2));
myTextLine.y = 150;

addChild(myTextLine);
myTextLine.addEventListener(Event.ENTER_FRAME, onLoop);
}

}
import flash.events.*;
private function onLoop(e:Event) {
e.currentTarget.rotationY += 3;
e.currentTarget.rotation = mouseX;
}
}
}

This code show how to use PerspectiveProjection, projectionCenter tranform, point

var img:Bitmap=new Bitmap(new heart(158, 58));
img.x=-158/2;
img.y=-58/2;
var holder:Sprite=new Sprite();
addChild(holder);
holder.x=stage.stageWidth/2;
holder.y=stage.stageHeight/2;
holder.addChild(img);

var pp:PerspectiveProjection=new PerspectiveProjection();
pp.fieldOfView = 120
pp.projectionCenter=new Point(holder.x,holder.y);
holder.transform.perspectiveProjection=pp;

function swingImage(e:Event):void {
	holder.rotationY+=3;
}
this.addEventListener(Event.ENTER_FRAME, swingImage);

druva.addEventListener(Event.ENTER_FRAME, rightAnimation);

function rightAnimation (e:Event):void {
  if (druva.x <= 300) {
	druva.x += 1;
	if (druva.x > 300) {
	  druva.x -= 300;
	}
	druva.rotation += 10;
  }
}

Just playing with Text this is my second update for text effects

Flash is great!!

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;
			}
		}
	}
}

The below code shows how to use the class

import druva.NumberUtil;

trace('500', NumberUtil.getParity(500));
// true
trace('489', NumberUtil.getParity(489));
// false
trace('5', NumberUtil.getParity(5));
//false
trace('1', NumberUtil.getParity(1));
//true
trace('400', NumberUtil.getParity(400));
//false

This is the actual class

package druva {
  import flash.display.Sprite;

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

    public static function getParity(num:Number):String {
		return (num % 2) ? 'odd' : 'even';
	}

  }
}
