Check connection with Zinc

function isConnected():Boolean {
var results = mdm.Network.checkConnection();
return results;
}
var hasConnection = isConnected();
mdm.Dialogs.prompt(hasConnection);

Internet Connection: Flash 8 Only.

var connected:Boolean = false;
function checkConnection():Void {
var myLoadVars:LoadVars = new LoadVars();
myLoadVars.onHTTPStatus = function(httpStatus:Number) {
if (httpStatus != 0) {
connected = true;
} else {
connected = false;
}
delete this;
};
myLoadVars.load("http://www.apple.com");
}
checkConnection();

SetTimeout : Flash

function testMe() {
 trace("callback: "+getTimer()+" ms.");
}

var intervalID:Number = setTimeout(testMe, 1000);

// clearTimeout(intervalID) // for clear the timeout

Dynamically placed buttons

It's simple, yet I often forget this.

var myMC:MovieClip;
var i = 1;
var pad = 5;
while (i<6) {
        trace(" i : "+i);
        myMC.duplicateMovieClip("myMC"+i, i);
        myMC.removeMovieClip();
        this["myMC"+i]._x = this["myMC"+(i-1)]._x+(this["myMC"+(i-1)]._width)+pad;
        this["myMC"+i].onRollOver = function() {
                trace(this);
        };
        i++;
}

Retreiving a Flash movie's domain name

Use the LocalConnection object to get the domain name of the server where the Flash movie is located.

var localDomainLC:LocalConneciton = new LocalConnection();
myDomainName = localDomainLC.domain();
trace( "My domain is " + myDomainName );

This will print out something like this:

My domain is example.com

Use Flash's MovieClipLoader Class

I'm always forgetting the syntax for this...

var oImgListener = new Object();
oImgListener.onLoadInit = function(target_mc)
{
     trace(target_mc._name + "  load complete");
     ...
}

var mclImg = new MovieClipLoader();
mclImg.addListener(oImgListener);
mclImg.loadClip("http://myurl.com/path/to/swf/or/jpg", mcImgLoader);
