I found the Dummies book to contain much more detailed info than this book. This book doesn't walk you through using the CodeWarrior IDE at all (unlike Dummies). I bought both books and always seem to go to the Dummies book most of the time (I have the Dummies book tabbed with sections highlighted). The version of the included CodeWarrior Lite seemed more up to date, but I could never compile with it. I switched back to the version of CW Lite I got with Dummies and have been using that (CW for Palm OS is on order for me!).
I also found that this book contained too much code and not much explanation of what it was doing. The Dummies book shows a short snippet of code and explains what it's doing step by step. Also this book doesn't explain how to use the CW IDE very well (I think I already said that). It basically just says, "Make your project and compile it." Hmmm, not much help there.
I'm an experienced C and Java programmer. Mixed experience for 10 years on Unix using gcc and NT using IBM's Visual Age for Java. I've found after two weeks of Palm Programming with the Dummies book, that I can come to this book just to pick up a small nibble of info here and there if I can't find it in Dummies first.
I did find some of the code examples on the CD useful. The Dummies book lacked info on floating point arithimetic. This book didn't explain it well either, but at least it had some code examples to look at for the calculator program code. You pretty much need the full blown CW for PalmOS compiler to debug your code (about $370 when I ordered it). This book contains no Conduit info. Dummies has some limited Conduit coverage.
Overall, I highly recommend the Dummies book. Could ya tell?
