There are several API mechanisms which will work cross-system; mailslots and named pipes come to mind immediately. MSMQ, a message-queuing service provided by Microsoft, is available as a COM object; there's a tremendous whitepaper covering MSMQ and VFP written by Robert Green available in the MSDN Library - you can access it online through the MSDN web site msdn.microsoft.com/vfoxpro

You can also write your own out-of-process COM objects and rely on DCOM for RPC services within VFP.

If I were doing this and the communication were one way, and I couldn't use MSMQ, I'd probably use named mailslots via the Windows API. You could easily code the server as an out-of-process COM server and use DCOM; it's all natiuve VFP that way.
