Thank you very much for the kind words, Michael. If you enjoyed the first edition, then I have great news for you as the second edition (which we're finishing up now) has been beefed up considerably. In fact, I was so keen on coming out with a much more advanced book that I enlisted the help of two long-time CodeProject/CodeGuru contributors (Aravind Correra and Andrew Whitechapel) to co-author with me. The result is SUBSTANTIALLY more in-depth and complete text. If you want, I'll email you when the book is finished. In fact, I'll also ask MS about posting a sample chapter here from the new edition since we're only about 2 weeks from being finished. Thanks again for the kind remarks. Cheers, Tom Archer
