.NET Forum / .NET Framework / CLR / July 2006Sending Window Messages from an MFC app to a Windows Firm tray application
Hello, I have an MFC MDI application and a Windows Forms (2.0) Tray Icon application. I want to run a command on the tray application via my MFC application. There is a "Register" context menu command on the tray icon application. I want to call the Register command from my MFC MDI application. I thought of a windows message. How do I do it? Is there any other better mechanism to do so? Thanks, Janiv Ratson. If you know the class of the window on the tray application you can use FindWindow() to get the window for the class. Then you can use either PostMessage() or SendMessage() to send a message to that window. You should be able to use the same message ID that is generated when you select the functionality from the menu in the application. Basically, the tray application will not know the difference between the message that came from the outside or the one from its own menu.
