>I was following a usenet thread on using the VFPOLEDB driver, and it seems that it does not return enough schema information to ADO.NET for the OleDbCommandBuilder to generate updating logic (according to David Sceppa at Microsoft). This sounds pretty serious, is there a bugfix in the works or a comment from other MS guys?

It was announced at Essential Fox that the VFPOLEDB driver will be updated to support more .NET features in the next release. In this rev you're stuck with plain SQL commands for most things...
