I bought this book a while ago but I am now just going through it for my new job. I am about 2/3 of the way thru and while it does have some good information, the code samples are complete and utter TRASH!! My god if one simple application of his actually worked without hours of figuring out what HE DID WRONG I would believe Bush is an intelligent man. Stay away from this garbage -- the authors website doesn't work either so basically you're screwed.
