Create a class derived from Cwnd. have a member variable of that class the same as your control. Set the pointer of your control to the member variable. Now that window class can call your events.

Now, create a member variable of that class in your control. Create the window at construction. Then pass the handle to the window to other threads. They post a message which in turn is handled by your windows class which then fires the events on your control via the pointer in which you set earlier.

It is rather confusing and complicated until you know it. Then it seems rather silly and simple. Still confusing. But simpler.

Good luck. Hopefully this helps you. It is about as good as i can get with the time i have.
