Flash Projector: Stopping multiple instances from running

Sometimes we do not want user to launch multiple instances of a standalone(projector) Macromedia Flash application. A friend of mine had similar requirement and I came with a simple script that stops another instance from running. I am using LocalConnection Object for this and I know, you guessed it right? Yeah its very simple and intuitive approach.

Place the following code on the first frame of the application, before any other code.

var _lc:LocalConnection = new LocalConnection();
if(!_lc.connect("myapp")) {
 //You can handle the event in any way you want,
 //I am here just closing the projector.
 fscommand("quit");
}

So as soon as another instance is launched, it would check if connectionName(myapp) is in use, if yes then it quits. Hope it helps someone.
