Have you checked out hentzenwerke.com? Whil sells a number of books that touch upon this subject area. In particular, Jim Booth's book is excellent in showing how to build applications from the ground up and Peterson/Paddock's book on Enterprise issues, including client/server is good as well.

>Would you buy a book if it showed how an application was built from scratch to finish? I would. Building your subclasses, include files; normalizing your data and inserting business rules, etc. An application that incorporated commonly needed features such as data maintenance forms, user access, etc. And then continued to build it up, say to client-server &/or make it internet enabled. Is there any book out there that does this? I am not capapble (yet!) to write such a book, I am looking for one and suggesting it.
>Even if an author(s) took on understanding an application already written such as TasTraders and explained it from start to finish would be nice. And it would sell too.
>I'm amazed i havent heard or come across a book as this.
