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 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::ActionNotify(int actiontype)
{
if (actiontype == OADVISE_UPDATE)
{
NotifyDialog("Record has been updated");
}
return;
}
