While this book does cover a lot of topics, it is simply too sketchy and poorly written to be of much use. I have not read it cover to cover, but I have used about half the chapters while trying to learn various aspects of VB. As an example, I used the chapter on creating a help system and found it to be very frustrating. The examples given were very poor and way too sketchy. Some of the figures were wrong and the examples were poorly connected. I figured out the basics of writing a help system using this chapter, but it was a very frustrating experience.
