Hello,

I have a class, which starts a new thread.
from this thread events can be fired.
How can i fire this event in the class-creator-thread?


thx
 
Read up on Delegates. You can have the creater pass a Delegate to your
thread and have the thread call the delegate when it wants to notify the
creater.

That's only going to help if the creator thread is a UI thread, or
something else which implements ISynchronizeInvoke. Just calling a
delegate created by the creator thread isn't going to make it execute
in that thread.

Your creator thread will need to be running some kind of message pump,
whether your own or the normal Windows one. If your creator thread is a
UI thread, you can use Control.Invoke/Control.BeginInvoke. Otherwise,
you might want to use a producer/consumer type queue, with the creator
thread waiting on the queue and the other thread putting work items on
the queue.

See http://www.pobox.com/~skeet/csharp/threads/deadlocks.shtml for an
example of a producer/consumer queue.
