Appending the system menu of other windows
Posted on 2009-05-15
I'm writing a program that allows the user to change the priority of the process from the system menu of any window owned by that process. I can add the menu item easily using the AppendMenu or InsertMenuItem APIs from user32, but the WndProc method doesn't catch anything with windows outside my own application
If I click my menu item that was added to my program's form's system menu, then it raises the event properly. I'm guessing I need to use subclassing (I've seen someone use GetWindowLong) to do this properly, but I can't figure it out.
Thanks in advance,
