Application.BeforeModal Event (Visio)
Published: July 16, 2012
Occurs before a Microsoft Visio instance enters a modal state.
Visio becomes modal when it displays a dialog box. A modal instance of Visio does not handle Automation calls. The BeforeModal event indicates that an instance is about to become modal, and the AfterModal event indicates that the instance is no longer modal.
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.
