Hi,

I was trying to link a UI I made in C# to the backend which is coded
as a DLL in VC++.

I used the DllImport attribute to invoke the dll functions. Is there
any similar mechanisms by which I can invoke member functions of
classes defined in the dll?

Is there any way I could instantiate an object of a class defined in
the dll?

I am new to C#/dll's et al so I am not too sure if these questions
make sense. But if anyone can provide some info on this and more
importantly provide pointers to articles/examples on these topics it
would be a tremendous help.

Thanks.
