Kazvash che SetKeyboardState raboti i upravlyava NumLock-a , a v MSDN pishe :

Because the SetKeyboardState function alters the input state of the calling thread and not the global input state of the system, an application cannot use SetKeyboardState to set the num lock, caps lock, or scroll lock indicator lights on the keyboard.

Zega si preodolyavam murzela i shte go probvam .

Tiq ot Micro$oft sa ludi. I te ne znaqt akkvo pravqt
