This method recreates the OraDatabase and OraDynaset objects referenced within the data control and reestablishes a dynaset using the SQL statement from the RecordSource property and the connection information from the Connect and DatabaseName properties.
If an existing dynaset has been assigned to an object variable in Visual Basic, then Refresh creates a new dynaset for the data control, but the old dynaset continues to be available for use until all references to it are removed.
