ActionNotify Method

Applies To

OAdvise

Description

The ActionNotify method is called by a dynaset when that dynaset has performed an operation. You do not call ActionNotify; the ActionNotify method of your OAdvise subclass is called by the dynaset.

Usage

void ActionNotify(int actiontype)

Arguments

actiontype

actiontype will have one of the following values:

Actiontype Value
Description
OADVISE_MOVE_FIRST
// dynaset moving to first record
OADVISE_MOVE_PREV
// dynaset moving to previous record
OADVISE_MOVE_NEXT
// dynaset moving to next record
OADVISE_MOVE_LAST
// dynaset moving to last record
OADVISE_MOVE_TOMARK
// dynaset moving to dynaset mark
OADVISE_REFRESH
// dynaset refreshing
OADVISE_DELETE
// dynaset deleting current record
OADVISE_ADDNEW
// dynaset adding a new record
OADVISE_UPDATE
// dynaset updating
OADVISE_ROLLBACK
// session (that dynaset is part of) is rolling back
Remarks

When you subclass OAdvise, you can override the ActionNotify method. After an instance of your OAdvise subclass is attached to a dynaset (by way of the OAdvise::Open method) your instance receives calls to its ActionNotify method. Use an ActionNotify method to perform processing after a dynaset has performed an action.

The unoverridden ActionNotify method of OAdvise does nothing.

Example

This example puts up a notification dialog whenever a record is updated.

void YourOAdvise::ActionRequest(int actiontype)

{

if (actiontype == OADVISE_UPDATE)

{

NotifyDialog("Record has been updated");

}

return;

}
