>If you want to use a VFP front end, you can use RDS to talk to a VFP COM object on a web server. You'll need to convert to and from cursors and ADO RS's as you can't pass a cursor through COM. It appears you can also use RDS to pass XML strings too, I've done a little experiementing and this appears to work although I have not seen any documentation on this.

Great!
Lets see:
1) The client instances an RDS control
2) The RDS connects to the server with .Connect method. I'm guessing that oRDS.Connect connects to server ODBC. If the server connection is to FoxPro ODBC, that seemingly would allow an ISAM ({xbase} seek,scan, etc;) on the server's DBFs/CDXs.
3) Would a server mounted VCX/DLL provide the means to to x-query (not SQL) the server DBFsCDXs.

How does an RDS control (instanced at client) xBase DBFs/CDXs on the server. The only method to connect with server data is .SQL (or so it seems) with RDS.

MAYBE we could solve this with a simple project.

Client program:
.. VFP form (EXE) with an entry for a SSN#, and an output for a name
.. Client instances an RDS Datacontrol that connects to server
Client/Server DBFs/CDXs:
.. SSNName.DBF fields SSN and Name
Process:
.. Client forwards a SSN to the server (How?)
.. Server (VFP DCOM?) uses SSN to look up name in SSNName.DBF (How?)
.. Server VFP "finds" a match (eg seek(clientssn,[SSNName],[Name])=.t.) (How?)
.. Server returns name to client (XML, string, RDO?) (How?)
.. Client form places retrieved name on Form (How?)
