Getting keys pressed..

[Sulik]

I want my application to realize which keys have been pressed, before the system gets it.
A very confusing phrase, eh? That's because I don't know English..
I mean when the user presses, for example, alt+Tab or ctrl+alt+del, my application has to execute the specified handler for these keys, before the system will do it, or let the system execute the default handler.

I do not know if it is such simple to catch the CTRL-ALT-DEL key, because this key Combination is handled by a special interuppt.
If you really want to trap this key, iam afraid you have to write an own keyboard driver and include it into your OS.

Hmm... allright.. even if I won't be able to catch the ctrl+alt+del, how can I get the others?

Try to use HOOKing engine to trap keypressings before the system seen it.
Happy programming!))
