hmCal allows you to add simply and quickly a complete calendar functionality into your 4D application. It is always guaranteed that functionality between Macintosh and Windows is identical.

The advantage of hmCal is that it can be integrated extremely simply into existing solutions. So appointments, virtual appointments (they do not have to exist in data records), repeated appointments etc. in complex situations (rights of access, on-the-fly-creation) can be represented and manipulated.
