This is a great book, mostly due to the amount of code examples that it has. With most of the advanced Visual Basic books that I've used, I often have to go look up additional information in help, only to find he exact same information there, too. The silly "hello, world" demos included with these books are not real-world enough for me and still leave me wondering how to apply the concepts to my application. I've never seen any of the demos from this book anywhere else, and they are mostly all excellent. This book has its share of "hello, world" demos too, but they are balanced by some of the best real-world examples I've seen in any other book on programming. It's obvious that the author has actually done this type of programming in real life. I can honestly say that I know exactly how I'll implement my distributed application now that I have this book.
