From the article: COM - .NET Interoperability in Visual Basic
There are still plenty of reasons to use COM, Microsoft's Component Object Model architecture, in .NET. My article "COM - .NET Interoperability in Visual Basic" explains how it's done using Excel, but it's written to be as short and easy to understand as it can be, and we all know the world isn't like that.
Do you call COM objects from .NET? Which objects? What problems have you run into?
