We are starting up a new .NET project and leveraging existing code and the team's experience with VFP by using VFP COM+ components with a new .NET Web form front end. In the Web form we used a command such as dsOrder.ReadXML(New StringReader(OrderDetailXML)) to read an XML string from the VFP COM+ component into a dataset and then we use it in our .NET Web form that displays the order details. This works great for displaying the data, but we are not sure how to send updates back to VFP COM+ via XML strings. What we want to do is generate a .NET XML Diffgram to send back to our VFP COM+ component that will use this to do the update, but not sure how or if we can generate a Diffgram on the .NET site that VFP will accept (we really don’t want to send all the fields back in the XML for update when only a few changed). What would you advise?
