The document that was opened.

The DocumentOpened event is often added to the EventList collection of a Microsoft Visio template file (.vst). The event's action is triggered whenever an existing document is opened.

If you're using Microsoft Visual Basic or Visual Basic for Applications (VBA), the syntax in this topic describes a common, efficient way to handle events.

If you want to create your own Event objects, use the Add or AddAdvise method. To create an Event object that runs an add-on, use the Add method as it applies to the EventList collection. To create an Event object that receives notification, use the AddAdvise method. To find an event code for the event you want to create, see Event codes.

You can add DocumentOpened events to the EventList collection of an Application object, Documents collection, or Document object. The first two are straightforward—if a document is opened or created in the scope of the Application object or its Documents collection, the DocumentOpened event occurs.

However, adding a DocumentOpened event to the EventList collection of a Document object makes sense only if the event's action is visActCodeRunAddon. In this case, the event is persistable—it can be stored with the document. If the document that contains the persistent event is opened, its action is triggered. If a new document is based on or copied from the document that contains the persistent event, the DocumentOpened event is copied to the new document and its action is triggered. However, if the event's action is visActCodeAdvise, that event is not persistable and therefore is not stored with the document; hence it is never triggered.

You can prevent code from running in response to the DocumentCreated, DocumentOpened or DocumentAdded event and all events from firing by setting the value of the EventsEnabled property of an Application object to False.
