how to block "alt+tab"

[Melque_Lima]

hi every one, fine?

i want that anyone gets out from  my program before closing it, and i need to block the function "alt+tab" that navigates through the windows.

i tried to create a hotkey, but it does not worked like bellow:

 

HotKeySet("!{Tab}", "Nothing")

While 1

sleep(50)
    EndIf

Func Nothing()
    ;
EndFunc

It might work with an accelerator. Check out GUISetAccelerators in the help file.

Yeah, I see that. It was worth a try.

Why is Alt+Tab an issue? Perhaps you can redesign your program/features. Maybe force the window to always be topmost, so if someone presses Alt+Tab, the window should automatically reappear. You could add a message with instructions telling the user what to do when this happens.

good idea, i can verify the window title and if its lost focus reappear the window program

Good luck. Any problems with it, then post a question in General Help and Support.
