HowTo simulate a 'dumb' terminal in 95/98/ME/NT/2K/XP

[Alexinuk]

If anyone can help with the following i'll be eternally grateful... One of the requirements of a project i'm working on is that users of this app are unable to access windows - i.e. when the computer is powered, windows loads, then our app. users shut their computer down from within the app, and must be unable to access windows with CTRL+ALT+DELETE, ALT+F4, ALT+TAB etc. I know that you can do this for 95/98 and ME by using some screensaver API calls, but apparently this won't work for all windows versions. any ideas? Thanks in advance, Alex

All key combinations (apart form Strg+Alt+Entf - here you'll need to replace MSGINA.DLL) can be handled and thus permitted by installing a windows hook. To get it work for your whole windows sessin, place the hook procedure inside a DLL. You'll find many informations about that in MSDN - try searching for SetWindowsHookEx.

Cheers Mate. Is this the only way? will this work on all windows (95/98/....etc)? Regards, Alex

Win98 doesn't have an MSGINA.DLL though does it?

And system-wide hooks (that one's inside DLLs) even work for catching all input. Alexinuk wrote: will this work on all windows (95/98/....etc)? Sure - do you expect anything else from MS? :)

Replacement of MSGINA.DLL is only needed for disabling Strg+Alt+Entf. All other key events can be handled by hooks. Alexinuk wrote: Win98 doesn't have an MSGINA.DLL though does it? Well I think it's only provided for WinNT and higher:~ :confused:
