The CD-ROM that accompanies this book contains more—and more comprehensive—material than the previous edition. You'll now find that the CD-ROM contains the code from all parts of this book, including the code snippets in the "Dear John, How Do IDear John, How Do I... ?" section and the full-blown sample applications found in Part III. Visual Basic is a rich, diversified development environment, and we've tried to provide useful, enlightening examples that cover all the major subject areas. This does impose limits on the depth of coverage possible in a single book, however. For example, we've provided a real, working example of a complete but relatively simple database program, but there's no way that one book can cover all aspects of the rich set of database programming features now built into Visual Basic. This book provides a quick start in the fundamentals of database programming with Visual Basic, but you might want to supplement it with a book devoted entirely to the subject if this is your main area of interest.
