Hello,

If you are using the COM programming interface, you can check the OnAnnChange event, which occurs when any property of an annotation object changes.

Hello,

The event is AnnAutomation.AfterObjectChanged Event. But since you are not using the Automation object, you may try to check the AnnContainer.AfterDrawingObjects or AnnContainer.BeforeDrawingObjects events.

If these events don't work with you, I think there is no way to check if the AnnotationObject has been changed in the non automated mode.

Thanks,
