Occurs before the application terminates in response to a user action in the interface. If any event handler returns True , the operation is canceled.


Private Sub expressionQueryCancelQuit( **_ByVal app As [IVAPPLICATION]** )

expression A variable that represents an InvisibleApp object.


NameRequired/OptionalData TypeDescription
appRequired[IVAPPLICATION]The instance of Microsoft Visio that is going to terminate.


A Visio instance fires QueryCancelQuit after the user has directed the instance to terminate.

  • If any event handler returns True (cancel), the instance fires QuitCanceled and does not terminate.

  • If all handlers return False (don't cancel), the instance fires BeforeQuit and then terminates.

While a Visio instance is firing a query or cancel event, it responds to inquiries from client code but refuses to perform operations. Client code can show forms or message boxes while responding to a query or cancel event.

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, seeEvent codes.
