Method; returns the total number of bytes downloaded by

or if a load operation has not started. This method also returns
bytes can't be determined (for example, if the download was initiated but the server did not
transmit an HTTP content-length).
Example
The following example uses a ProgressBar instance and a LoadVars object to download a text file.
When you test the file, two things write to the log file: whether the file loads successfully and how
much data loads into the SWF file. You must replace the URL parameter of the
LoadVars.load()
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
ActionScript:
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) {
