1. Using VFP7 Command Window, I instantiated and made a call to the VB6 DLL. It was a success. The VB6 DLL, located on my local machine, was able to access the Visual FoxPro tables on a network drive.
2. Using C# Console Application, I referenced and used the VB6 DLL. It, too, was a success.

Does this help narrow down what the problem could be?

Thank you for your time and effort.
