Hi Rick,

You may want to try using Microsoft's ATL library for creating COM objects. It's relatively easy to create lightweight COM objects that can be instantiated in VFP. I have recently created a class which I use for doing date conversions. I have found that a simple COM object takes about a sixth of the time it takes to instantiate a native VFP Custom class.
Calling methods and accessing properties is straightforward and the marshalling that is done during automation calls makes it easy to pass strings between VFP and C++.
