I have a client with an existing VFP 5.0 application, compiled, it appears, using Refox, so that it cannot be decompiled, original author is gone, you get the picture.

They are interested in redeveloping the application, as well as extending it to the web and other integration points, for which VFP 7.0 seems ideal. Question is, can VFP 5.0 and 7.0 share DBC/DBFs without corruption or other problems? Ideally, this would allow us to build incremental functionality to replace the existing software without having to do a massive (and doubtless, painful) cut-over. We could actually even use VFP 6.0 if we needed to to get compatibility, and would give some added stability over the existing solution at least.

Comments and suggests always appreciated.
