    if (oledbConnection != null && oledbConnection.State != ConnectionState.Closed )  
        oledbConnection.Close();  
}  
Private oledbConnection As System.Data.OleDb.OleDbConnection  
Public Overrides  Sub ReleaseConnections()

        oledbConnection.Close()  
    End If  
End Sub  

Remarks

This method is called repeatedly during component design by the runtime engine and at the end of component execution. The components then release any connections that were opened and maintained in AcquireConnection. This method is called only when OfflineMode is false.
