Hi Jim,

Looks to me like you need to make each of your VFP apps into DDE Clients and Servers. Trust me, DDE is fast and cheap on memory usage. I have done it with two VFP apps talking to each other, a VFP app talking to a C++ program that talks to firmware which then sends responses to the C++ app which in return sends responses to the VFP app.

If the VFP in which the I/O command is originally issued cannot deliver (cause it does't recognize the table as open or some such), then it would be aware of other active VFPs and it would pass the command on to them to execute, and the one which does returns the info/result to the originator so that the originator keeps on truckin.

>What this would let me do, for instance, is to have a ALL-VFP application where the front-end was on terminals all over the place but the back-ENDS (note the "s") could be in a highly secure and power protected environment. This would give me *most* of the benefits of an expensive SQL-server type facility ALL BY VFP and with the speed and simplicity of VFP.

>I would accept that I had to have an "INI-type" file to "control" this, possibly to direct/limit the search for VFPs and also to restrict to certain tables. I would also accept that all tables in such a scheme had to be in DBCs.
