How to pass flashvars to standalone flash player

Try to pass command-line parameters to an .exe projector.

Alternatively, you might want to wrap your .swf on another, and have the wrapper load it with parameters, like this:

var loader:Loader = new Loader();
var request:URLRequest = new URLRequest("your_cool_app.swf");
request.data = "a=1&b=2"
loader.load(request);
