Try turning it around! If you were using c# for the middle tier what
would you pass....?
You would have to stay with the standards that your front end and middle
tier both understand or go to a portable standard such as XML.
The fact you are using VFP for the middle tier is moot unless you are
using a VFP front end in which case you can pass cursors around (which
is great) otherwise I would say XML is fine and maybe should be used
between layers in vfp only apps for future proofing.
That's right. The issue of what standard to pass information
will be dependent on the capabilities of each tier IMO.
Before Flash was capable of dealing with XML we developed
a VFP middle tier that received text streams from a Flash
interface, queried a SQL Server backend and passed text
streams back to the Flash interface. We didn't develop the
Flash interface, we just provided the Flash developers with
a couple of lines of "hook" code.
