VB6 and C# interface inheritance

by: Roy Pereira | last post by:

I have an application that is composed of a set of "Content" dlls and a viewer application. The viewer calls a standard set of functions that are present in all the dlls. I maintain this by making my contnent dlls implement an interface created in vb6. The viewer application is bound to this interface.
