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 "+lvByte" of "+lvByt" bytes.");
loadvars_pb.setProgress(lvBytesLoaded, lvBytesTotal);
}
};
my_lv.onLoad = function(success:Boolean) {
