>Is there another way to address a DLL created with VFP other than the COM interface?

If you meant create a DLL with a set of functions, each one is a VFP function - no, it is not possible. If you meant access to DLL functions as to API functions, - yes, you can, but these functions are just a pure wrapper for interface and features for COM components DLL that are standard - so C++ program, for example, will be able to ue that COM object.
