InvisibleApp.BeforeQuit Event (Visio)
Occurs before a Microsoft Visio instance terminates.
When programming with Microsoft Visual Basic, use the BeforeDocumentClose event instead of the BeforeQuit event. The code in a Visual Basic project of a Visio document never has the chance to respond to the BeforeQuit event because the project is a property of a document, and all documents are closed before the BeforeQuit event notification is sent.
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.
