Using a union message handler is a great idea!.
That is exactly what IB does in their SampleApp using a delegate and a message handler method.
This is IB's code:

delegate void MessageHandlerDelegate(IBMessage message);

And for thread safety:

?public void HandleMessage(IBMessage message)
??????? {
??????????? if (this.InvokeRequired)
??????????? {
??????????????? MessageHandlerDelegate callback = new MessageHandlerDelegate(HandleMessage);
??????????????? this.Invoke(callback, new object[] { message });
??????????? }
??????????? else
??????????? {
??????????????? UpdateUI(message);
??????????? }
??????? }

Their IBMessage is an abstract class which they extend in a whole bunch of "message" objects.? Then process the messages with a Huge switch/case statement to up the user interface.?

I'm trying to figure out a way to make it cleaner for my own general use.??? And figure out how they (IB) do some neat stuff with some of the UI controls.
Hope it works.

Thanks
