Alt keydown ?
Hi, what i need is if the ALT key is pressed to ignore it.
Like for example if you hit Ctrl+Alt+Del it opens the taskmgr.
So all i need is for when the form is open if you hit Ctrl+Alt+Del the Alt key wont work so then nothing happens.
Well either the Alt or Ctrl key
Thanks for any help

CTRL+ALT+DEL is a low-level system hook with expected system response. I see no honest reason to block it, really.

It needs blocking as i am coding a simple screen locker.
I already have a timer running so when or if the task manager is opened it will close it.
But the problem is CTRL+ALT+DEL function :/

Sounds like you are trying to create a kind of Kiosk app, which should help with your search.

Look, you'll need a kernel-mode driver to disable C-A-D. Even then, I still think that disabling C-A-D represents a serious problem to users if you will distribute your application among third party users.
Screen locking is performed by windows itself (if you configure it to do so), and similarly, you can create a simple screen saver with password protection.
If your application is supposed to run at your work in a controlled environment, restiction of user permissions is done by system administrators using the standard Windows administrative tools.
