Events and Threads - Visual Basic .NET

Michael D. Ober

Can events generated in a worker/background thread via RaiseEvent be handled
safely in the main/display thread? The contents of the event object will be
used to update the display of a Windows forms application.

Thanks,
Mike.

Michael,

Events are really just indirect method calls and they run on the
thread that raise the event. If you want something to run on the UI
thread you have to use Control.Invoke/BeginInvoke.
