The source of the event.
A ComponentChangingEventArgs event that contains the event data.
When you create a NIB: Events and Delegates.delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see
This example demonstrates registering a ComponentChanging event.and handling the
Public Sub LinkComponentChangingEvent(ByVal changeService As IComponentChangeService) ' Registers an event handler for the ComponentChanging event. AddHandler changeService.ComponentChanging, AddressOf Me.OnComponentChanging End Sub Private Sub OnComponentChanging(ByVal sender As Object, ByVal e As ComponentChangingEventArgs) ' Displays changing component information on the console. Console.WriteLine(("Type of the component that is about to change: " + e.Component.GetType().FullName)) Console.WriteLine(("Name of the member of the component that is about to change: " + e.Member.Name)) End Sub
