The CAD (or Secure Attention Sequence) cannot be trapped by any process other than MSGINA.
So from VB you can't....
If you are very brave you can attempt to re-write the GINA. You will need to do this in C++. However, conventional wisdom says that this is a very hard thing to do! It is also extremely likely to prove fatal to the operating system several (many) times during development.
My advice: Rethink why you need to trap CAD! thread222-571474 thread222-541509 offer some additional reading...

If at first you don't succeed, skydiving is not for you.
If I were you I'd do a keyword search in this forum on this subject. It has been asked in here plenty of times before. Mind you, to save you time: no, it can't be done in VB for NT/2000/XP/2003. Doing the keyword search will provide you with the explanations.
