I have a standard VC++ Win32 DLL that exports some functions.


I may be wrong, but I don't think we have many experts in C++ in this
newsgroup which focuses on the use of VBA within Excel.

You might be better trying a group such as
microsoft.public.vc.language

The OLB file provides a set of object class definitions for Excel.
In the VB world we would Reference the file rather than Import it - but
I don't know how that translates into C++
