HI Jeff,

I set it up so that properties can be set, after which a method is called. Do you mean that I shouldn't have exposed properties? So should I have another exposed method that sets the protected properties?
(Or do you mean a graphic interface? It doesn't have one.)

I tried building the DLL in VFP6, but it has the same problem.
