Ejemplos

En el ejemplo de código siguiente se crea un diseñador que proporciona comandos de menú de verbos de diseñador que llaman a métodos de IUIService. Para usar el ejemplo, compile el código de ejemplo en un ensamblado y agregue una referencia al ensamblado en una aplicación Windows Forms. Si usa Visual Studio, se IUIServiceExampleControl agrega automáticamente al cuadro de herramientas. Agregue una instancia de IUIServiceExampleControl a .Form Para acceder a los comandos de verbo del diseñador que invocan IUIService métodos, haga clic con el botón derecho en la superficie del control o haga clic en el glifo de etiqueta inteligente del control y seleccione un elemento en el panel de etiquetas inteligentes.
