Visual C++ library

Hi,

I created a static library with visual c++(6.0) and I am trying to use it
with an ActiveX project.
I inserted the library in the Link tab(in projetc settings), but it keeps
returning:

error LNK2001: unresolved external symbol

I am shure the function name is right. What may be wrong? Could it be the
way i built the library? Should i include anything else in the project?

thanks a lot!
