CancelUpdate - method of object AdoRecordset

Description:
It is used for ending the edit mode and cancelling all modifications to the current record. The edit mode was started by the AddNew method (in this case the new record is cancelled) or by writing the values into the current record (record edit).
Syntax:
CancelUpdate
Calling:
oRs.CancelUpdate
See also:
Example:
Adding a new record into the table ("table1") and modifying the contents of the new record, by using the stored AdoRecordset object ("table1"), over the PmaAdo object ("/TestAdoDb"), that is already connected to the database (see DbOpen), by the SQL query ("SELECT * FROM table1"). At the end, the adding of a new record is not confirmed by the Update method, but cancelled by the CancelUpdate method.
