EVENT: Connection::ExecuteComplete
ExecuteComplete
RecordsAffected, pError, adStatus, pCommand, pRecordset, pConnection
The
ExecuteComplete
event can be fired after either a
Command.Execute, Connection.Execute, Recordset.Open, Recordset.Requery,
or
Recordset.NextRecordset
method has completed execution. This event is one of two command execution management events that can be called. The other event is
WillExecute
.
An event is simply a subroutine that can be called automatically after a specific operation has occurred. This subroutine can contain any code that you need to run when the event occurs. The subroutine will only be called if it is included in your code. Future calls to the event subroutine can be cancelled by setting the
adStatus
parameter to be the
adStatusUnwantedEvent
constant (see table below) before the event returns.
There are six parameters that are passed to this event.
The
RecordsAffected
parameter is a long value that is the number of records affected by the execution.
The
pError
parameter is an
Error
object that contains information about the occurrence of any errors and/or warnings. This parameter requires that the
adStatus
parameter be set to the
adStatusErrorsOccurred
constant, otherwise the
Error
object is not created.
The
adStatus
parameter is one of the
EventStatusEnum
constants and defines the status of the event. If the command that caused the event to fire was successful, this parameter is set to
adStatusOK
. If the command was not successful, this parameter is set to
adStatusErrorsOccurred
. To prevent unwanted future firings of this event, set this parameter to
adStatusUnwantedEvent
before the event returns.

adStatusUnwantedEvent
5
The operation that generated the event cannot generate future events
The
pCommand
parameter is the
Command
object that was executed.
The
pRecordset
parameter is the
Recordset
object that resulted from the execution of the command.
The
pConnection
parameter is the
Connection
object that is associated with the execution of the command.
Code (Visual Basic):
' Use the WithEvents keyword to designate that events
' can be handled by this Connection object
Dim WithEvents objConn As ADODB.Connection
' Note how the object name, objConn, is incorporated into the event Sub name
Private Sub objConn_
ExecuteComplete
( RecordsAffected As Long, _
ByVal pError As ADODB.Error, _
adStatus As ADODB.EventStatusEnum, _
ByVal pCommand As ADODB.Command, _
ByVal pRecordset As ADODB.Recordset, _
ByVal pConnection As ADODB.Connection )
' place any code you desire here, for example
If adStatus = adStatusOK Then
Print "Records affected = " & RecordAffected
Else
Print "ExecuteComplete Status = " & adStatus
End If
End Sub
