can you explain copy hook - are yu trying to attach to the windows clipboard? if so have alook at SetClipboardViewer and related API in the SDK.

also for crypto libraries have a look at
crypto++ written by Wei Dai at http://www.eskimo.net/~weidai/index.html that has so many crypto systems in it you'll be spoilt for choice.

Thanks, ShaunWilde
I want to monitor the copy action of windows. If copy a file into(and out) the given directory, then the hook will notice it and let me do something. Can it be implemented?
I have found the crypto libraries at the URL you give me. It is very useful,thank you.

ah  if you wish to monitor a directory then you may wish to use the FindFirstChangeNotification and releated API or use the ICopyHook interface. Is it help on these that you require help on?

for FindFirstChangeNotification

see

the code given should be probably placed in its own thread (i.e. away from any GUI thread) and then post in its findings.
