What I'd hoped would be an excellent book to introduce me to COM and DCOM has turned out to be an exercise in futility.I've been used to the quality tutorials from WROX press and Microsoft Press where they lead you step by step through an exercise. The author's first example in Chapter 2 I did not even realize was an example until they expected me to run it in chapter 3! There were no instructions on how to create the COM client, just several lines of code. This set the tone of the book.When I tried to run the author's code examples they failed.There were also multitudinous spelling errors and discrepencies between the Figures and the instructions.Though the authors clearly know their subject, I will have to find another book if I wish to learn COM and DCOM. This book is basically worthless as far as the examples go.
