I'm using this book as a text for Visual Basic 6 class. The further you get into the book, the more mistakes (especially in the code for the exercises!). One Exercise (Chapter 11) was so riddled with mistakes that it was a guessing game.
I don't expect everything to be spelled out.
I do expect the example code to be complete, consistent and correct. Fortunately, I have a great teacher.

Also, most good books/publisher have a website where you can download errata/corrections to the mistakes and typos in the book. Prentical Hall has purchased the book. If there is a correction page, I couldn't find it. I usually can find such pages since I have worked in the publishing business.
