Query: Man, tough crowd. Have you folks READ THIS BOOK?

I've been writing code and designing hardware for 20+ years. In that time I have designed many graphics programs and always had to re-invent the wheel. This book should be titled "How to Avoid the Pain of Windows Graphical Programming and have fun at the same time". The other thing is the extensive examples and freeware tools offered with the book. Cheaper than a class.
