COM and COM+

In this book, you are going to learn how COM technology works and how to interact with the services. The reason we refer to things as COM in the first half of the book instead of COM+ is that, in reality, COM+ is COM with a few enhancements. At the end of the day, what you are really writing are COM components that work in COM+ applications. The book also shows you how some of the most interesting services work internally. This leads us to another question—in the world of Visual Basic, why do we need to know how things work internally?
