Use the Exclusive property to True to specify that a table should be opened exclusively when calling the Open method or when setting the Active property to True. When the Exclusive property is set to True and the application successfully opens the table, no other application can access the table. If the table for which the application has requested exclusive access is already in use by another application, an exception is raised.
A table must be closed (Active property should be False) before changing the setting of the Exclusive property. Do not set Exclusive to True at design time if you also intend to set the Active property to True at design time. In this case an exception is raised because the table is already in use by the IDE.
