Additional Features and Capabilities

• Access to the WorkArea with SDE API functions in addition to OLE DB and ADO.
• ADO Recordset.Find (IRowsetFind interface), which is used by many data aware controls, such as DataCombo, for example.
• ADO Recordset.Resync method (IRowsetRefresh interface).
• ADO Recordset.Filter property (View OLE DB object and all its interfaces).
