VB.Net and C++

[Peter Aitken]

I need to call an existing C++ DLL from a VB.Net program. I am confused
about how the data tupes relate - for example, when a DLL function returns a
pointer, how do I handle that in VB?

Alternately, is there a way to write a module or class in my VB.Net program
in C++?

Thanks
