Hi everyone!
I have some problem, and have no clue how to resolve it.
I wrote some C# application which shows nice GUI and then creates
long-running worker thread. I want now to recaive some kind of notify, when
the worker thread is terminated (or aborted). I've been trying delegates and
ThreadPool.RegisterWaitForSingleObject(), but this doeas not work, becouse
invoked method works within the different thread. I've got exceptions like:

Additional information: Controls created on one thread cannot be parented to
a control on a different thread.

In MFC I would send message to the window. How to resolve this problem ?..



Thanks for any help

Paul.

Use Control.Invoke.
