Resizing a Full Flash Site - problem

programming flash
1

I’m trying to resize a full flash site. I’m using if statements to do this. Is there a better way? I want the resize to hold the proportions. Additionally, my if-statement method is too cumbersome. It doesn’t always keep the content in the center (doesn’t resize to the content to be in the center).

Scenario: The base is a black background that resizes according to the window size. The main image stays in the middle of the page.


var holderAllMC:MovieClipLoader = new MovieClipLoader();
var holderAllMCListener:Object = new Object();
holderAllMCListener.onLoadProgress = function(target, loaded, total) {
    loader.percent.text = Math.round((loaded/total)*100)+"%";
};
holderAllMC.addListener(holderAllMCListener);
holderAllMC.loadClip("background.swf?uniqueID="+getTimer(), holderAll.subholder);
holderAllMCListener.onLoadInit = function() {
    loader._visible = false;
    loader.percent.text = "";
    resizeSite();
};
backs._width = Stage.width;
backs._height = Stage.height;
loader._x = Stage.width/2;
loader._y = Stage.height/2.5;
function resizeSite() {
    var wwn:Number = Stage.width;
    var hhn:Number = Stage.height;
    var wwnd:Number = 840;
    var hhnd:Number = 608;
    if (wwn<=500) {
        holderAll._xscale = 60;
        holderAll._yscale = 60;
        holderAll._x = Stage.width/2;
        holderAll._y = Stage.height/2.5;
    }
    if (hhn<=450) {
        holderAll._xscale = 60;
