>Hi Jim. I pulled some articles about using VFP for Remote Automation. In the examples, they assume you want to use the automation server with products other than VFP, so they use long character strings to transfer records. These strings will then be parsed and used by the client.

Joseph,

Passing a record set back to the client by any means other than ADO/RDO is of questionable value in building middle tier objects. The whol;e reason for middle tier objects is to separate the data from the interface by providing a middle layer that handles requests from the interface and delivers data from the backend. The nature of the data should be insultated from the itnerface such that the interface only deals with the middle tier object. The interface should have no idea how the data is gotten ro in what format it exists.

To get the table style of data you asked about I would use RDO or ADO to the middle tier.
