How to get back strings from a external DLL

I have a VB.NET-Program, that makes calls to a external C++ function .

This part is alread done and is working well.

The values are given by a structure and come back with a structure

Now my question:
I want extend the structure that come back from the DLL with a string

There should also come back a string ( an Error-description ) from this DLL
to the VB.NEt program.

Where can I get examples , what datatypes must be used on both sides ( C++
Structure-type and VB.NET type for this string )

Thanks
Peter
