ADO » Recordset » RecordChangeComplete
- Syntax:
- RecordChangeComplete (adReason, cRecords, pError, adStatus, pRecordset)
- pRecordset
- The pRecordset parameter is the Recordset object to which this event applies.
- adReason
- The adReason parameter is one of seven of the EventReasonEnum constants that describe what operation occurred that allowed this event to fire. Note that there is a total of fifteen of these constants, but only the following seven can actually be used by this parameter.
- cRecords
- The cRecords parameter is a long value that is the number of the records that were changed.
- pError
- The pError parameter will be set only if an error occurred and the adStatus is set to adStatusErrorsOccurred. It is an Error object that describes the error.
- adStatus
- The adStatus parameter is one of the EventStatusEnum constants that describes the current status of the event. If the action that triggered this event was successful, then the agrument will be set to adStatusOK. If an error occurred, it will be set to adStatusErrorsOccurred.
Called after one or more rows have been changed.
The RecordChangeComplete event can be fired after the values for one or more Records
in the Recordset have been changed.
The operations that can trigger this event would be either:
- The first call to the AddNew, CancelBatch, CancelUpdate, Delete, Update, or the UpdateBatch methods,
- The first and all subsequent calls to those same six methods.
In contrast, the WillChangeRecord event can be fired before any pending changes in the values for one or more Record objects have been completed.
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.
There are five parameters passed to this event.
EventReasonEnum Constants
| Constant | Value | Description |
| adRsnAddNew | 1 | A record is added |
| adRsnDelete | 2 | A record is deleted |
| adRsnFirstChange | 11 | Any operation that makes the first change to a record |
| adRsnUndoAddNew | 5 | An add is cancelled |
| adRsnUndoDelete | 6 | A delete is cancelled |
| adRsnUndoUpdate | 4 | An update is cancelled |
| adRsnUpdate | 3 | A record is updated |
EventStatusEnum Constants
| Constant | Value | Description |
| adStatusCancel | 4 | Cancels the operation that fired the event |
| adStatusCantDeny | 3 | Cannot cancel pending operation |
| adStatusErrorsOccurred | 2 | Indicates that warnings and/or errors occurred |
| adStatusOK | 1 | The operation that fired the event was successful |
| adStatusUnwantedEvent | 5 | The operation that generated the event cannot generate future events |
Examples
Code:
' Use the WithEvents keyword to designate that events
' can be handled by this Recordset object
Dim WithEvents objRecSet As ADODB.Recordset
' Note how the object name, objRecSet, is incorporated into the event Sub name
Private Sub objRecSet_RecordChangeComplete( adReason As ADODB.EventReasonEnum, _
cRecords As Long, _
ByVal pError As ADODB.Error, _
adStatus As ADODB.EventStatusEnum, _
ByVal pRecordset As ADODB.Recordset )
' place any code you desire here, for example
If adStatus = adStatusErrorsOccurred Then
Dim objError As ADODB.Error
For Each objError in pRecordset.Errors
Debug.Print vbtab; objError.Description
Next
End If
End Sub
