MessageWindow.WndProc Method

The WndProc method corresponds to the native Windows WindowProc function.

The following code example is an override of the WndProc method in a class derived from MessageWindow. It examines incoming Windows-based messages. If a message has the identifier WM_CUSTOMMSG, it calls the RespondToMessage callback function providing information obtained from the WParam and LParam parts of the message. This code example is part of a larger example provided for the MessageWindow class.

 // Override the default WndProc behavior to examine messages.
 protected override void WndProc(ref Message msg)
 {
  switch(msg.Msg)
  {
   // If message is of interest, invoke the method on the form that
   // functions as a callback to perform actions in response to the message.
   case WM_CUSTOMMSG:
    this.msgform.RespondToMessage((int)msg.WParam, (int)msg.LParam);
    break;
  }
  // Call the base WndProc method
  // to process any messages not handled.
  base.WndProc(ref msg);
 }
}
