in form1 it has swf object
how can vb.net play this script into that swf object

<script type="text/javascript" src="http://Radioonline.ir/RadioonlinePlayer.Js"></script>

Why not change that Script file the have the script type = javascript tags in the source script and change the extension to (*.htm), then add
a webbrowser object that has the URL set to "http://Radioonline.ir/RadioonlinePlayer.htm"?
It should work.
Doing that will make the browser object run that javascript, rather than a SWF object.
