Last change on this file since 1056 was 1011, checked in by Sam Habiel, 14 years ago

UCPatientAppts: Fixes printing empty table bug reported by EHS.
DAccessTemplate: Various usability improvements.
CGDocumentManager: Fixed Delegate code so that it can operate asynchronously
CGAVView: Some temporary fixes (not totally usable): Added non-functional Delete Slots menu option; Added Background worker for saving acccess slots
In the future, Delete Slots will work; and will use ADO.net Updatable datatable for saving access slots.
calendarGrid: just some comments for now
AssemblyInfo: bumped version up to v1.4.2
