Accessing C++ DLL from C#

Asked by szaranger in Microsoft Visual C++, C++ Programming Language, Microsoft Visual C#.Net

Tags: dll, from, accessing

I'm trying to access functions from a C++ DLL from C#. I neither can reference nor register the dll. Is it possible for me to access the functions within C#?  But it's possible to access the DLL from VB6.
