Introductory material on the history of Basic has been left out of this book, along with some beginner-level instructions for using Visual Basic. This leaves more room for the good stuff! There's plenty of introductory material for beginners in several popular introductory books on the Basic programming language. We've found that most readers are already somewhat familiar with Visual Basic and are looking for new information to improve their skills and to add to their personal toolboxes of techniques.
