Question

I have a window that show the result of multiple worker threads, but my worker threads should work with no interrupt(almost) so I want to post my notification data to the main window, I’m currently using BeginInvoke but it has a problem! I should call EndInvoke but where? I should create another thread just to service this? another option is using PostMessage directly but since I’m learning to work with .NET I prefer a .NET solution instead of a platform call(if available). So what should I do here to post something to main thread without blocking my worker threads?

Answer 1

You should simply use BeginInvoke, which is the direct equivalent of posting a message. You don’t need to call EndInvoke at all unless you are interested in the return value.

If you are interested in the return value then the answer to “where do I cann EndInvoke” is kind of obvious: call it at the last moment before you need the return value in order to proceed.
