Identifiers of these types are found as fields in various classes to identify events; for example, InvokedEvent. They are also found in the event arguments passed to UI Automation clients.
It is not possible to create custom events.
In the following example event handler, the AutomationEvent in the event arguments is compared with the AutomationEvent that identifies the Invoked event.
''' <summary> ''' AutomationEventHandler delegate. ''' </summary> ''' <param name="src">Object that raised the event.</param> ''' <param name="e">Event arguments.</param> Private Sub OnUIAutomationEvent(ByVal src As Object, ByVal e As AutomationEventArgs) ' Make sure the element still exists. Elements such as tooltips can disappear ' before the event is processed. Dim sourceElement As AutomationElement Try sourceElement = DirectCast(src, AutomationElement) Catch ex As ElementNotAvailableException Exit Sub End Try If e.EventId Is InvokePattern.InvokedEvent Then ' TODO Add handling code. Else End If ' TODO Handle any other events that have been subscribed to. Console.WriteLine("Event: " & e.EventId.ProgrammaticName) End Sub 'OnUIAutomationEvent
