Query: Very Good Content But Some Impossible Exercises

Okay, this may seem trivial to the more advanced users, but the exercises in this book are deadly. They give the briefest of instructions and have no corresponding text on the CD! I mean, would it have killed the author to include the code so the reader can check his or her work? There were hundreds of megs of free space, but alas, no code to check your work! Forget the website, and e-mailing the tech support address at the site resulted in an automated response sent two days later! Arrrrggggghhhh! I dare someone of intermediate or lesser skill level to complete Exercise 4 without flinging the book out the nearest window! Good luck!
