範例

/// </summary>
/// <param name="provider">The UI Automation provider for the control.</param>
private void RaiseInvokeEvent(IRawElementProviderSimple provider)
{
if (AutomationInteropProvider.ClientsAreListening)
{
AutomationEventArgs args =

AutomationInteropProvider.RaiseAutomationEvent(InvokePatternIdentifiers.InvokedEvent,
provider, args);
}
}

''' <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
備註
模式事件不應只由模式實作引發。 例如, InvokedEvent 每當叫用控制項時,應該透過或透過 Invoke 滑鼠或鍵盤輸入引發 。 如此一來,用戶端就可以得知系統事件。
