Hello All,

I know there are some products which can "hook" or "intercept"
API and DLL calls and even access the parameters
so long as the user knows the paramter types.

The products include WinScope and API Vision.

I do use WinScope but I'd like to do my
own hooking (for DLL function calls) and Id like to tell
if someone has my functions hooked.

Can someone please give me a pointer.

Get PROCHOOK.EXE on ftp.microsoft.com in the /Softlib/MSLFiles directory.
This file contains sources for the PROCHOOK.DLL described in an old issue
of the Microsoft Systems Journal.

Can someone point me at a program that can tell me the exported functions,
their return types, and their parameter types? I would like to access
a DLL that I don't have documentation on.

Will WinScope, API Vision, or PROCHOOK do this? If so where would I
get WinScope or API Vision?

Thanks in advance for any help?

Jerry
