Wanting to enter the world of Pocket PC development, I have been searching for books on the topic. I am already an accomplished programmer and was simply looking for specifics on the topic. With a title like Pocket PC Developer's Guide, I thought I had found that resource. Unfortunately, I was very disappointed.
The book deals mainly with Windows CE programming in general and very little with Pocket PC specifically. When it does approach the topic, it still skips over many of the required and/or recommded practices for this platform. For example, nowhere in the book is there mention of handling of the SIP or other Pocket PC-specific details. Nowhere is there any mention of Pocket PC-specific messages in the WndProc. How is one supposed to learn anything about Pocket PC programming from this book when the author clearly doesn't discuss the bulk of what makes the platform unique.
What the author does do, however, and in excess, is preach. He goes on and on about his programming techniques and, in fact, spends chapters on the topic of his styles. Again, this is supposed to be a book on PocketPC development, not a general programming book.
I ended up getting the Windows CE book from Microsoft by Boling. True, it deals mainly with Windows CE in general, but it has two large chapters on Pocket PC which provide more information on the specifics that in all of Krell's book!
Stay away from this book if you're looking to develop on the Pocket PC. You're not going to learn much here.
