Property Value

Type: System::Boolean

A Boolean value indicating whether one of the result sets has changed.

If you are not using the OnChange event, you can check the HasChanges property to determine if the query results have changed.

The HasChanges property does not necessarily imply a change in the data. Other circumstances, such as time-out expired and failure to set the notification request, also generate a change event.
