Remarks

A Microsoft Office Visio instance fires QueryCancelMasterDelete after the user has directed the instance to delete a master.

  • If any event handler returns True (cancel), the instance will fire MasterDeleteCanceled and not delete the master.
  • If all handlers return False (don't cancel), the instance will fire BeforeMasterDelete and then delete the master.

While a Visio instance is firing a query or cancel event, it will respond to inquiries from client code but will refuse 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.
