This demo shows how a Firebird database can be used for VisualPlanIt. It
|
||||
takes advantage of the prebuilt TVpFirefordDatastore.
|
||||
|
||||
NOTE:
|
||||
The project creates a new database on the fly. For reasons unknown at the moment,
|
||||
an exception is raised here if started from the IDE. This does not happen any
|
||||
more once the database exists.
