There are a couple of flaws with this book that I can see.  If you want to learn ADO.NET, this book definitely misses that.  The issue the Deitel's ran into was deciding where to draw the line in database development content.  Since this book is geared towards education, it would have been nice to see more database content.  The other flaw that I see is the chapter layout.  This might be a personal preference rather than a flaw, but I would liked to have seen file access and database development earlier than graphical content.  The database chapter contains a section that discusses reading and writing XML with datasets.  I felt that should have been contained in the XML chapter.  I also think that generics and collections should be moved ahead of the ASP.NET and web services content as this book is supposed to focus more on Visual Basic.
