IUIService Interface

Définition

Active l'interaction avec l'interface utilisateur de l'objet de l'environnement de développement qui héberge le concepteur.

public interface class IUIService
[System.Runtime.InteropServices.Guid("06A9C74B-5E32-4561-BE73-381B37869F4F")]
public interface IUIService
[<System.Runtime.InteropServices.Guid("06A9C74B-5E32-4561-BE73-381B37869F4F")>]
type IUIService = interface
Public Interface IUIService
Attributs

Exemples

L’exemple de code suivant crée un concepteur qui fournit des commandes de menu détaillé du concepteur qui appellent des méthodes du IUIService. Pour utiliser l’exemple, compilez l’exemple de code dans un assembly et ajoutez une référence à l’assembly dans une application Windows Forms. Si vous utilisez Visual Studio, la IUIServiceExampleControl boîte à outils est automatiquement ajoutée. Ajoutez une instance de l’objet IUIServiceExampleControl à un Form. Pour accéder aux commandes de verbe du concepteur qui appellent IUIService des méthodes, cliquez avec le bouton droit sur l’aire du contrôle ou cliquez sur le glyphe de balise active du contrôle, puis sélectionnez un élément dans le panneau des balises actives.
