Jim,

I haven't used any of this, but what I have run across is the following:

A series of ADO articles in FoxPro Advsior, Spring and Summer, 2000.

VfpCom.ComUtil which has CursorToRS and RSToCursor methods.

ADO recordsets can be bound to any VFP form control but a grid. Use the MS FlexGrid for grid functionality bound to an ADO recordset.

Maybe John Petersen will drop by here with some advice or answers to specific questions.


>I am using VFP 6 as a front-end to a SQL Server 7 database in a new application, and I have been working with ADO objects for the data access mechanism. After exploring views and SQL Pass-through, these seem to be a bit easier to use for me.

I haven't thought of a good way to deal with parent-child relationships in the user interface yet, however. I would like to be able to get an ADO recordset (as a child in a relation) into a grid, for example, bound to a parent key, much as SET RELATION works in regular VFP tables. As an alternative, there is a way to load ADO data into an array, which could be used to fill a list box or something. I was just wondering if I am missing anything obvious here. Like any way to bind a grid to something other than a cursor.
