Query: Falsus in unum, falsus in omnibus?

This was, potentially, an excellent book. In what must be presumed to be the haste with which it was put together, however, it is riddled with errors and inconsistancies. In addition, the CD that is a part of the book appears to have been designed for some other (perhaps unpublished?) edition; the Macmillan web site has almost 4Mb of corrections and additions. That I managed to learn Visual Basic from it suggest, perhaps, that my 40 years of programming was worth something. But it should have been easier, and the book should have been significantly more carefully edited.
