Version Added: Visio 2007

Private Sub expression _QueryCancelSuspendEvents(ByVal app As [IVAPPLICATION])

expression An expression that returns a Application object.

Parameters

Name

Required/Optional

Data Type

Description

app

Required

[IVAPPLICATION]

The instance of Microsoft Visio in which firing of events is going to be suspended.

Return Value

nothing

A Visio instance fires QueryCancelSuspendEvents after client code has directed the instance to suspend events.

  • If any event handler returns True (cancel), the instance fires SuspendEventsCanceled and does not suspend events.

  • If all handlers return False (don't cancel), the suspension occurs.

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.
