I'm wondering if there is a better way of doing this since I don't like the instanceof and the if statements.

When this thread reads a message, I want it to notify the Windows Forms message loop running in the main thread that a message is ready. How can I do that? In win32 I would do a PostMessage, but that function does not seem t...
