I've gotten about halfway through this book in the past two weeks and I feel like I'm learning enough where I can start writing my own simple games once I'm done with it. I started from knowing VB.net pretty well (for business apps), but not knowing the first thing about DirectX or Game Programming. That said, the editing of the code samples in this book is atrocious. The code samples in the book almost never match those on the CD and you have to figure out "what they mean" most of the time, debugging stuff yourself. Another dumb thing is that whoever wrote the code doesn't know how to use arrays, and always Dims a 4 element array as MyArray(4) instead of (3). Lastly, they don't tell you to enable "key preview" on your forms, so if you didn't know to do that from reading it in another .Net book, the keyboard handler functions would never work for you. Bottom line is that this book can help you learn elementary game programming in VB.net, as long as you know the language reasonably well (decent VB6 would be enough), and you won't get too frustrated trying to reconcile the code in the book and on the CD. It's too bad: If they had gotten their act together, this could have been a 5 star book.
