    Looking for help on code for trapping the keys 'Ctrl-Alt-Del' so they don't go to the operating system for processing, while the dialog is open. Can't seem to find any info on this subject. Maybe someone has other ideas on this subject. Thanks for your help. STC :rolleyes: Stephen Crawford

      Hmmm... making this would create quite a security hole. Especially for win NT where the system uses these keys to ensure the logon dialog is generic. However I do think it's possible for win 95-98-ME as I know of a "remote controlling" program (Sub7 [yup, the trojan]) that can disble Ctrl-Alt-Del on the controlled "users" (target,victim) computer. (No, it's not the kind of stuff I do on the net... I just keep me informed :) ) Anyway, good luck... (and if you find something plz post it somewhere (article on codeproject? :rolleyes: ). Cheerz

          You might try using a system hook, specifically the one for low level keyboard input. The function call is something like SetWindowsHook or SetWindowsHookEx, not entirely sure on the name. Hopes this helps any!
