KEYBOARD HOOK numlock problem

[korte]

I prepare a program, which switches it on, NUMLOCK button.
Keyboard hookl I ban it the another pressing.
The program works half.
Turns it on the numlock LED.
Catches the button presses and bans it.
But not well, because the state of the LED does not change simply, but onto the function the program is not with an effect.
