Document.QueryCancelStyleDelete Event (Visio)

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

Version Added: Visio 2000

Private Sub expression _QueryCancelStyleDelete(ByVal Style As [IVSTYLE])

expression A variable that represents a Document object.




Data Type





The style that is going to be deleted.

A Microsoft Visio instance fires QueryCancelStyleDelete after the user has directed the instance to delete a style.

  • If any event handler returns True (cancel), the instance fires StyleDeleteCanceled and does not delete the style.

  • If all handlers return False (don't cancel), the instance fires BeforeStyleDelete and then deletes the style.

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, see Event codes.
