How can I edit a Recorset using ADO

How can I edit a recordset using ADO.

I take it you are looking for something like EDIT mode like in DAO.
This does not exist in ADO. You simply change the values of the fields in the recordset.
By moving to another recordset or by using the update methode the changes are commited.
To cancel a change use the CancelUpdate methode of the recordset.
