Interop: Windows Message Pump

Question

I have this main method that contains a loop to retrieve the messages from the messageQueue that the main window is running. If a key is released(KEYUP) on the keyboard the message goes to a function wich responds when a certain key is pressed. If the escape key is released the function post the quit message in the queue (PostQuitMessage(0)). The problem accures when I close the window by pressed the Close button in the controlbox. The "while(MessageQueue.GetMessage(out msg ,form.Handle ,0 ,0))" line gets hilited and the error shows. Cannot access a disposed object named "MainForm" So I suppose the Form is disposed before I can get any message from the queue that tells that the program has ended. Even if I nest the while loop in another while loop with form.Created as condition the error shows. I could nest this loop in a try catch block. But I then I can't debug the application properly. Is there a way around this problem? [STAThread] static void Main() { MSG msg = new MSG(); MainForm form = new MainForm(); form.Show(); while(MessageQueue.GetMessage(out msg ,form.Handle ,0 ,0)) { MessageQueue.TranslateMessage(ref msg); MessageQueue.DispatchMessage(ref msg); switch(msg.message) { case (uint)WM.KEYUP: Functions.CheckKey(ref msg); break; } Application.DoEvents(); } }
