ADO Event Handler Summary

Two ADO objects can raise events: the Connection object and the Recordset object. The ConnectionEvent family pertains to operations on the Connection object, and the RecordsetEvent family pertains to operations on the Recordset object.

Connection Events: Events are issued when a transaction on a connection begins, is committed, or is rolled back; when a Command executes; when a warning occurs during a Connection Event operation; or when a Connection starts or ends.
Recordset Events: Events are issued around asynchronous fetch operations as well as when you navigate through the rows of a Recordset object, change a field in a row of a Recordset, change a row in a Recordset, open a Recordset with a server-side cursor, close a Recordset, or make any change whatsoever in the Recordset.

The following tables summarize the events and their descriptions.
