I think this book irreplacable on my reference shelf. I use it everyday for work. If you do any Visual Basic work, I recommend that you get this book. It's only $15 and it has already paid for itself several times over. I use this book every day, and highly recommend it to anyone. A previous reviewer complained about a bad binding (true) and simple index. Since the all the language and method entries are alphabetic, I never really looked at the index. I also always use the 'See Also' listings at the end of each term to find related commands.
