The authors of this book did not write this well. The first 4 chapters are excellent, but Chapter 5 throws information that doesn't make sence at you. Then you can't read the rest of the book. An example sentence in Chapter 5 is "Before a variable is used, its data type must be declared with either the Dim or the Global or Static modifier." It gives the defenitions for those words later on, makng everything confusing. Don't expect anything good from te CD-ROM - it only has the very basic parts of Visual Basic. I recommend that nobody should read this book.
