Tamar,

Thanks for your suggestions.

1. I understand your first one.

2. I'm not clear what you are saying in the second one. I am using a VFP client to instantaite my COM server for testing, although the ultimate client will be a C++ app at this point. Is this what you are suggesting?

Set up the log in the server's Init method, storing the filename in a property. Then, it only takes one line to add some debugging code anywhere in the object:
