How can I disable all keys including Ctrl+alt+Del , Alt+Tab and Windows Keys when a user is interacting with my form? I have a borderless form which covers the entire screen and I have to probhit the user from getting out from it. Thanks,

You cannot normally disable Ctrl+Alt+Del because it's the Secure Attention Sequence, used for bringing up the Windows Security dialog. You can stop many other keys from having their usual effects using a keyboard hook. Paul DiLascia documents how to do it - in C++ - in this MSDN Magazine column[^]. Stability. What an interesting concept. -- Chris Maunder

Apparently if you replace one of the system DLLs on NT based system you can bypass control-alt-del but I forget the name of the DLL in question. If you google for NT Admin Tips you might find it and where to get the replacement DLL. I'd advise against this modification without client permission though. :)

Yuo can't disable the Ctrl-Alt-Del sequence unless you write your own GINA.DLL and replace the system version with yours. You also can't write the new GINA in C# either... RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome
