[IVSELECTION]

The selection of shapes that is going to be grouped.

Remarks

A Microsoft Visio instance fires QueryCancelGroup after the user has directed the instance to group a selection of shapes.

  • If any event handler returns True (cancel), the instance fires GroupCanceled and does not group the shapes.

  • If all handlers return False (do not cancel), the grouping is performed.

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 use 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.
