How can I detect desktop changes ?
I capture it with GetDesktopWindow(), while there are, for example, 4 open windows
Later I close one of them, I'd like to get that change right after I close that window. I mean another HWND should be reported.
Thank you :)
GetDesktopWindow() won't help you in that. You should probably not use that API at all. To do what you want (if I understood your right) you will need a system-wide hook. Check description of the SetWindowsHookEx API for more info.
Thank you but what should I hook ?
So someone could tll me which hook ?
Is this ignored because it is too easy for you ? :)
Hooking is not easy at all,Quote:

Thanks, I will search if there is another way to do instead of hooking
Until I can get the replies here and on other forums, I will make my skin thicker to asking more and more, I will also test how others mentally think about this too,
Thanks everyone for your time
Good!, it's good, butQuote:

Sorry, I didn't get an email notification about this one. I would use WH_CALLWNDPROC hook and try to catch WM_CLOSE messages sent to your windows of interest. But like Turingmachine pointed out, Windows hooks aren't a trivial thing. This one, most certainly, will have to be a global hook to monitor messages for processes other than yours, which means you will have to put it into a DLL. I haven't programmed Windows hooks since XP and I'm sure they added new restrictions to them under Vista and Windows 7. Study the link I gave you above. There's an example on how you can place a Windows hook there.
PS. What exactly are you trying to accomplish? Maybe there's an easier way to do it.
