I’ve been having a look at some of the samples on the Visual Basic Resource Center to see what’s possible when we start using interop between VB6 and .NET. Here are some of my favourites. This article, “Sharing ADO Recordsets Between Visual Basic 6 and

Adding to the My namespace in VB .NET

Just as an aside - after experimenting with the Interop Forms Toolkit earlier this year I wondered how InteropToolbox ended up in the My namespace – it seems like a useful thing to be able to do. I didn’t have to look far, the answer was in the ActiveXControlHelpers.vb

VB6 Interop and TlbImp vs AddRef

I’d always assumed that creating a Runtime Callable Wrapper by adding a reference to the COM component in Visual Studio would generate the same interop code as was generated by using the command line tool TlbImp. That would seem not to be true in at least
