I've got a Medical Billing software package that's written in VFP6 but I'm not sure about linking into it. It already has a scheduler that links to the patients and uses DBI Technologies Schedule control. It's mostly for a single office or office with some remotes. I'm about to release the new version which is using the DBC and views and getting it ready to make it switchable to a SQL backend or VFP backend as well as developing a Web based front end for remote offices using IIS and Active Server Pages.
