>>Add the VFP DLL's type library to the VB Project References, then you can use it like any other object, e.g. (once added to Project References)

Dim oVFPClass As MyVFPDLL.MyVFPClass

Does it seem like the error is generated by VB or by the VFP COM object?

If it's the VFP COM object, add code to this class's Error() event as follows:

LPARAMETERS nError, cMethod, nLine

AError(laError)
COMReturnError("Error: " + Transform(nError) + Chr(13) + ;
    laError[1,2] + Chr(13) + ;
    "From: " + cMethod + ", Line: " + Transform(nLine))

and see if you get a better error message.
