Visual Basic's popularity is due to its dual nature: It's relatively easy for aspiring programmers to learn, yet powerful enough for professional application developers. Visual Basic 6: Visual QuickStart Guide, like VB itself, will appeal to both camps. It's so accessible that novices will be up and programming in no time, while more seasoned programmers will find it a helpful quick reference to important tasks. Of the many VB books on the market, few address the beginner. Visual Basic 6: VQS assumes absolutely no programming experience, but instead relies on the time-tested Visual QuickStart teaching method. Screenshots, sample code, and concise, step-by-step instructions guide you through a carefully selected series of examples designed to get you programming right from chapter one. And once you've mastered the basics, you can use the clearly tabbed format to refer to topics you need to brush up on. - from Amzon
