When you have multiple users accessing/updating the same appointment schedule simultaneously for the same owner, what is an advisable technique for reflecting the latest updates for all users?
This is really a general database front end design question rather than a WinSchedule-specific question. Database and adapter configurations provide ways for you to control the way records are locked (for example, optimistic or pessimistic record locking). You could, for example, disable an appointment for all users (except the one editing it) when it is being edited, and show the reason in a dialog, etc., but this is a function of the database layer and WinSchedule cannot get involved with this because it does not communicate directly with the database.
