    if (AutomationInteropProvider.ClientsAreListening)
    {
        AutomationEventArgs args = 
            new AutomationEventArgs(InvokePatternIdentifiers.InvokedEvent);

''' <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

Remarks

Pattern events should not be raised just by a pattern implementation. For example, an InvokedEvent should be raised whenever the control is invoked, either through Invoke or through mouse or keyboard input. In this way, clients can be informed about system events.
