How to affect size of movies using loadMovie CS4, as3

Question

I have loaded a .swf into my main timeline, but it's quite large. I am trying to get it to fit in the constraints of my current movie. I have read that by putting it into a movie clip, it will constrain to that dimension. How do I accomplish this?

If you know what scaleX and scaleY you will need you could just add it your code. Something like this:
loader.scaleX=loader.scaleY=50;
But if the content you will load is of different sizes and will maybe need different scales you could use code like below.
import flash.display.Loader;
import flash.events.Event;
import flash.display.MovieClip;
import flash.net.URLRequest;
var loader:Loader=new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, handleComplete)
loader.load(new URLRequest("banner.swf"));
addChild(loader);
function handleComplete(e:Event){
var target:Loader=Loader(e.currentTarget.loader);
     trace(target.width)
Depending upon what you need to do you could change that trace to some kind of measurement of the width and then use some arithmetic to scale the clip to a specific size.
