Exempel

I följande kodexempel skapas en designer som tillhandahåller menykommandon för designerverb som anropar metoder för IUIService. Om du vill använda exemplet kompilerar du exempelkoden till en sammansättning och lägger till en referens till sammansättningen i ett Windows Forms program. Om du använder Visual Studio läggs IUIServiceExampleControl automatiskt till i Toolbox. Lägg till en instans av IUIServiceExampleControl till en Form. Om du vill komma åt designerverbkommandon som anropar IUIService metoder högerklickar du antingen på kontrollens yta eller klickar på kontrollens smarta tagggenlyf och väljer ett objekt från panelen för smarta taggar.
