Syntax
WillChangeRecord adReason, cRecords, adStatus, pRecordset
RecordChangeComplete adReason, cRecords, pError, adStatus, pRecordset
Parameters
adReason
An EventReasonEnum value that specifies the reason for this event. Its value can be adRsnAddNew, adRsnDelete, adRsnUpdate, adRsnUndoUpdate, adRsnUndoAddNew, adRsnUndoDelete, or adRsnFirstChange.cRecords
A Long value that indicates the number of records changing (affected).pError
An Error object. It describes the error that occurred if the value of adStatus is adStatusErrorsOccurred; otherwise it is not set.adStatus
An EventStatusEnum status value.When WillChangeRecord is called, this parameter is set to adStatusOK if the operation that caused the event was successful. It is set to adStatusCantDeny if this event cannot request cancellation of the pending operation.
When RecordChangeComplete is called, this parameter is set to adStatusOK if the operation that caused the event was successful, or to adStatusErrorsOccurred if the operation failed.
Before WillChangeRecord returns, set this parameter to adStatusCancel to request cancellation of the operation that caused this event or set this parameter to adStatusUnwantedEvent to prevent subsequent notications.
Before RecordChangeComplete returns, set this parameter to adStatusUnwantedEvent to prevent subsequent notifications.
pRecordset
A Recordset object. The Recordset for which this event occurred.
Remarks
A WillChangeRecord or RecordChangeComplete event may occur for the first changed field in a row due to the following Recordset operations: Update, Delete, CancelUpdate, AddNew, UpdateBatch, and CancelBatch. The value of the Recordset CursorType determines which operations cause the events to occur.
During the WillChangeRecord event, the Recordset Filter property is set to adFilterAffectedRecords. You cannot change this property while processing the event.
You must set the adStatus parameter to adStatusUnwantedEvent for each possible adReason value in order to completely stop event notification for any event that includes an adReason parameter.
