You should also read Robert Green’s book "Visual FoxPro Client Server Development" published by Pinnacle/Whil Hentzen. It was published in 1996 as a special report series and may or may not be available. You might try calling Pinnacle Publishing at 800.788.1900 (as listed in the book).
The book was focused on VFP3 and SQL Server 4.2. It works with VFP6 and SQLS 6.5 and 7.0 without modification.
The sample code works with the SQL Server sample database "PUBS". Although the framework is incomplete (and he states so) it will get you well on you way to understanding the issues of remote data and large-scale databases. Remember even at their largest possible size VFP's native databases are tiny.
Any book that is focused on VB does not take into consideration the most powerful aspects of VFP remote data capabilities, SQL Pass through (not remote views as some people think).
Now that SQLS 7.0 is OLE DB and OLE Server enabled you should also consider learning ADO/RDO and OLE Automation.
As you can see, VFP and large scale databases is a favorite subject of mine. I teach several courses on the subject.
Software engineers are trained to read and understand code; they are not trained in mind reading. Document the purpose not just the functionality.
