Intercepting Windows sequrity box

[MatsHulten]

Hi!

When in NT and W2K you are pressing Ctrl-Alt-Del followed by Enter you lock the computer.
Is there a way to intercept other keystrokes programatically and execute other functions/programs?

I know I can do this by purchasing some kind of macro program, but I'd really like to try it the hard way...

If you mean intercepting the Ctrl-Alt-Del specifically and running you own program rather than the Windows program,then you would need to look at writing your own GINA (somethingI've read about, but never tried).
If you just want to monitor all keystrokes for every process, then you need to Hook into the OS message queues. You can do this with Pure VB if your are monitoring a single process, but if you want to monitor all processes, then you will need to move the CallBack function into a C++ DLL (the code is not that complicated though). The function that you want to look at using for this is SetWindowsHookEx.
