The IMAPIControl interface is used to enable and disable a button control and to perform tasks when a user of a client application clicks the enabled control. Service providers implement control objects to create custom buttons on dialog boxes, such as configuration property sheets, that are defined with display tables.
For more information on working with display tables and control objects, see Display Tables.
