Directions for using VB DLL in C++/MFC

I have a DLL that I need to integrate to. From the documentation that came with this DLL, it looks like this was made to work with VB, but I am using C++ and MFC. The DLL contains type information that I can see in the OLE/COM Object Viewer. The DLL contains functions that I want my application to call, and events that I want my application to process.

I have been having a terrible time trying to look up information for how to integrate with this DLL because I don't really know what it's called. I have been searching for terms such as: Visual C++ MFC VB DLL ActiveX COM automation client class events handler sink references #import... but I haven't managed to find anything that tells me how to use this DLL in my project. Can somebody please point me in the right direction?

I am using Visual C++ 2005. Several times I have come across directions related to VC6.0, but I haven't been able to follow those directions.

Did you add the dll in Project->Reference?

I know how to do that, but I don't know what to do after that. I don't see any new classes in the class view. Does adding a reference define a class that I should be able to create an instance of? Does it make a class I can somehow derive from that I can override some functions for the events that I need to handle?

You have to register the dll in your system and make a wrapper classes from dll coclasses: either #import it or make "MFC class from Type Library".
