I am not sure where to ask this question.

I have written a few wrappers in c++ for applications also written in c++.

I wanted to see if I could hook some functions in a visual basic executable.

Here is how my hook works:

You make a dll and include all the exports (msvbvm60.dll) has. Like in my def file below. Now for hooking I do what I always do and in this case it would be something like

rtcMsgBox = myBox

The def file looks like this:

LIBRARY nadewrap.dll
EXPORTS

rtcMsgBox = MSVBVM60.rtcMsgBox
EXPORTSBASIC_CLASS_AddRef = MSVBVM60.BASIC_CLASS_AddRef
BASIC_CLASS_GetIDsOfNames = MSVBVM60.BASIC_CLASS_GetIDsOfNames
BASIC_CLASS_Invoke = MSVBVM60.BASIC_CLASS_Invoke
..

I tried only to put in the functions that the program needs. The program didn't start up.

My error:

I tried putting all the functions that msvbvm60 has and I still get the same error.

I tried removing the hook so it just 'fowards' the exact functions to msvbvm60.dll

Putting all the in depth stuff aside. Does msvbvm60.dll serve more purpose than just exporting functions?
