Implementing a C++ Class for use in Visual Basic
I have written a difficult class in C++ that I need to access from Visual Basic. I have written Dlls in C++ in the past that exported functions, but, never a class.
I have looked at the __stdcall and the .def file, but, I can see no way to export the class itself, only it's functionality.
In such a case, I would consider using COM, or possibly starting over and creating the same functionality without using a class, but, I really don't want to. Can anyone tell me the best approach to taking my existing C++ class and making the class itself accessible to VB?

How difficult is the COM wrapper, and any tips on getting started?
I have the book from MS Press "Inside COM" but it's overkill, I think!

I don't think that you can. I think you'll need to make a COM wrapper around the class to make it usable in VB. But if you do, then you can use it in any language. :)
Hope That Helps,
