I thought the original issue was to test for when someone elses application
was maximised, or became the foreground application, and then set the task
bar accordingly.
I agree this is not a very sensible thing to do, changing screen resolution
is one better solution that comes to mind, but I still would have thought
you could hook these messages and respond accordingly.

Be aware that ABN_FULLSCREENAPP is not a windows message. It IS a message,
but it is sent to a special callback function that a taskbar sets up when it
registers itself (and it uses SHAppBarMessage to do this). For your
information, ABN_FULLSCREENAPP's value 2 (see ShellAPI.pas), which is the
same as the value of the windows message WM_DESTROY. Try firing _that_
around your system ;-).
The key seems to be that Windows seems to know when a window is being made
full screen, and handles the sending of that message to the callbacks of the
taskbar(s). As another application is creating the problem window, there
seems to be no easy solution.
MSDN suggests that creating special full screen windows (it doesnt say how)
is not recommended. It says you're better to tell the user how to select the
AutoHide property of the toolbar!

Andrew Cooke.
