Let me right away start with a disclaimer. I bought this book even without browsing it through because I have enormous respect for the guy based on his older books such asThe Peter Norton PC Programmer's Bible-(where he was a coauthor)and books on C.Those at their times were very useful to me because they were written from field experience.This one.... seems just a rehash of online help.I rather read on this subject from someone who has been in trenches in this particular subject, even if they are not decorated veterans. For just Excel VBA for example Walkenbach and Koefler are much more useful.
