var my_mcl:MovieClipLoader = new MovieClipLoader();
var mclListener:Object = new Object();
mclListener.onLoadStart = function(target_mc:MovieClip):Void {
my_pb.label = "loading: " + target_mc._name;
};
mclListener.onLoadProgress = function(target_mc:MovieClip,
numBytesLoaded:Number, numBytesTotal:Number):Void {
var pctLoaded:Number = Math.ceil(100 * (numBytesLoaded /
numBytesTotal));
my_pb.setProgress(numBytesLoaded, numBytesTotal);
};
my_mcl.addListener(mclListener);
my_mcl.loadClip("http://www.helpexamples.com/flash/images/image1.jpg",

When you load files in the test environment, make sure you load an uncached file
from the Internet and not a local file if you want to see the progress bar work. A local
file loads too quickly to see the progress. Alternatively, upload your SWF file and test
your document on a server.
