Query: Can't decide who his reader is

My gripe with the book is he can't decide who his reader is. Quite a bit of the time he is writing to the VB programmer moving up to VB.Net. Other times he is writing to the very beginner, going over very basic programming concepts anyone who has done any programming would know (what is a variable?). And at other times, he assumes you know concepts of VB, that the programmer who has never used VB is not familiar with. And he doesn't get into object oriented programming concepts until the last Chapter, and not much then.
