Errata: Visual Basic .NET How to Program, 2/e

We wish to thank our many readers who took the time to email us with errata. If you find errata not listed on this page, please email us at Remember to include the book title and edition.

Note: You can determine which printing you have by looking at the bottom of the back of the second physical page in the book (page iv, but it has no page number). Just above the ISBN number is a list of numbers. For the first printing of the book, the list appears as follows:

10 9 8 7 6 5 4 3 2 1

The last number in the list is the printing number. So the above list indicates printing 1 and the following list indicates printing 2:

10 9 8 7 6 5 4 3 2
