I passed this exam today. While this book was helpful and covered most every exam objective in sufficient depth, it needs some work. For God's sake, when will somebody create an MCSD book that doesn't have a glaring error in every chapter? From wrongly keyed practice tests to glaring contradictions, this book had it all. Case in point, pp.126-127 "(the controls) collection is not a true Visual Basic Collection because it does not support the full member set that a Visual Basic Collection object has. However, it does have a COUNT property, as well as ITEM, ADD, and REMOVE methods." Umm...that's what a VB collection has. The content (when it was correct) was sufficient, but the book was soured by such errors. Did I mention get the Transcenders?
