Documents.QueryCancelDocumentClose Event (Visio)

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

Syntax

Private Sub expression _QueryCancelDocumentClose( ByVal doc As [IVDOCUMENT] )

expression A variable that represents a Documents object.

Parameters

Name	Required/Optional	Data Type	Description
doc	Required	[IVDOCUMENT]	The document that is going to be closed.

Remarks

A Microsoft Visio instance fires QueryCancelDocumentClose after the user has directed the instance to close a document.

• If any event handler returns True (cancel), the instance fires DocumentCloseCanceled and does not close the document.

• If all handlers return False (don't cancel), the instance fires BeforeDocumentClose and then closes the document.

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.
