Nothing. Just return from your event handler or whatever, so the UI can remain responsive. Then when you're told the operation finished, do whatever you need to do when it finishes. Asynchronous programming means you'll be called back when things happen, and in the meantime you should return control so other stuff can run. It doesn't mean that you should go into an infinite loop trying to force something async to run synchronously. —Jens
