ActionScript 2.0 Language Reference - Adobe Help and Support

Example
The following example uses a ProgressBar instance and a LoadVars object to download a text
file. When you test the file, two things are displayed in the Output panel: whether the file
loads successfully and how much data loads into the SWF file. You must replace the URL
parameter of the LoadVars.load() command so that the parameter refers to a valid text file
using HTTP. If you attempt to use this example to load a local file that resides on your hard
disk, this example will not work properly because in test movie mode Flash Player loads local
files in their entirety. To see this code work, add a ProgressBar instance called loadvars_pb to
the Stage. Then add the following ActionScript to Frame 1 of the Timeline:
var loadvars_pb:mx.controls.ProgressBar;
var my_lv:LoadVars = new LoadVars();
loadvars_pb.mode = "manual";
this.createEmptyMovieClip("timer_mc", 999);
timer_mc.onEnterFrame = function() {
var lvBytesLoaded:Number = my_lv.getBytesLoaded();
var lvBytesTotal:Number = my_lv.getBytesTotal();
if (lvBytesTotal != undefined) {
trace("Loaded "+lvBytesLoaded+" of "+lvBytesTotal+" bytes.");
loadvars_pb.setProgress(lvBytesLoaded, lvBytesTotal);
}
};
my_lv.onLoad = function(success:Boolean) {
loadvars_pb.setProgress(my_lv.getBytesLoaded(), my_lv.getBytesTotal());
delete timer_mc.onEnterFrame;
if (success) {
trace("LoadVars loaded successfully.");
} else {
trace("An error occurred while loading variables.");
}
};
my_lv.load("[place a valid URL pointing to a text file here]");

public load(url:String) : Boolean
Downloads variables from the specified URL, parses the variable data, and places the resulting
variables in my_lv. Any properties in my_lv with the same names as downloaded variables are
overwritten. Any properties in my_lv with different names than downloaded variables are not
deleted. This is an asynchronous action.
