Hello,

Is there like a way that I can turn Input devices (Keyboard/Mouse) OFF on a keydown event excluding one Key like for example (I hit "F11", all Mouse & keyboard keys are disabled excluding "F10", which I use to turn them all back on.

Awaiting your Ideas,
Regards,
Safi

This is absolutely impossible, for example, because there is no a way to disable Ctrl+Alt+Delete — the system won't let it no matter what you do.

I'm not sure that global disable of anything else is possible, but you should not try to disrupt OS that much. The whole idea is bad.

Unfortunately, you did not share you ultimate purpose. You should always start with it. So, it's hard to advise anything else, but maybe what you want is the "Kiosk mode"? Please see:

Hi Safi,

Assuming that you are trying to do this for your application only, why not just have a bool in your code that is something like AcceptInput. Then, detect the F11 key and set AcceptInput to false. If you detect the F10 key, set it to true. Finally, wrap all your other keyboard/mouse input handling code in an if block that tests whether AcceptInput is true. If it is, handle the input as normal, if it isn't, just move ignore.

If, however, you are trying to block all inputs for all applications, then I'm not sure that it is even possible, at least I certainly hope it isn't!

Hope this helps,
Ed

None of these are the solution I seek, I wish to lock my keyboard keys globally, I have a GlobalHook that listens to my keystrokes, and I want to make a (IF) block that activates when a certain keyUp event happens, and deactivate when another keyUp event accords, it's really important, and I assure you I'm not gonna abuse such knowledge, I'm sure it's possible, just cannot remember the method.

Thank you!
Safi
