I read through chapters 2-10 of this book, and although there were many good explanations of things, some explanations were lacking and left me frustrated. For example, the description of event handling didn't make any sense to me, even after I read it several times. After reading O'Reilly's Nutshell book on event handling, however, I had a clear understanding of the subject.
Also, Weinberger is right when he states that certain important details seem to be missing. For example, when reading the section on enumerations, I didn't see any description of how enumeration members get default-initialized.
After reading Chapters 2-10, I'm giving up on this book. I like it enough that I'll keep it on my bookshelf as a reference, but, at the same time, I'm not super-thrilled with the quality of this one.
