private void RaiseInvokeEvent(IRawElementProviderSimple provider)
{
    if (AutomationInteropProvider.ClientsAreListening)
    {
        AutomationEventArgs args = 
            new AutomationEventArgs(InvokePatternIdentifiers.InvokedEvent);
        AutomationInteropProvider.RaiseAutomationEvent(InvokePatternIdentifiers.InvokedEvent, 
            provider, args);
    }
}

''' <summary>
''' Raises an event when a control is invoked.
''' </summary>
''' <param name="provider">The UI Automation provider for the control.</param>
Private Sub RaiseInvokeEvent(ByVal provider As IRawElementProviderSimple)
    If AutomationInteropProvider.ClientsAreListening Then
        Dim args As New AutomationEventArgs(InvokePatternIdentifiers.InvokedEvent)
        AutomationInteropProvider.RaiseAutomationEvent(InvokePatternIdentifiers.InvokedEvent, provider, args)
    End If

End Sub

Keterangan

Peristiwa pola tidak boleh dimunculkan hanya dengan implementasi pola. Misalnya, InvokedEvent harus dinaikkan setiap kali kontrol dipanggil, baik melalui Invoke atau melalui input mouse atau keyboard. Dengan cara ini, klien dapat diberi tahu tentang peristiwa sistem.
