Esempio

Nell'esempio IUIServicedi codice seguente viene creata una finestra di progettazione che fornisce comandi di menu verbo di progettazione che chiamano i metodi di . Per usare l'esempio, compilare il codice di esempio in un assembly e aggiungere un riferimento all'assembly in un'applicazione Windows Forms. Se si usa Visual Studio, viene IUIServiceExampleControl aggiunto automaticamente alla casella degli strumenti. Aggiungere un'istanza IUIServiceExampleControl di a un Formoggetto . Per accedere ai comandi verbi della finestra di progettazione che IUIService richiamano i metodi, fare clic con il pulsante destro del mouse sulla superficie del controllo o fare clic sul glifo smart tag del controllo e selezionare un elemento nel pannello smart tag.
