RemoteAgent, classe
Mise à jour : novembre 2007
Permet de déployer des applications d'agent Smart Device sur l'appareil et d'échanger des données entre l'ordinateur de bureau et l'appareil de type Smart Device.
Espace de noms : Microsoft.SmartDevice.Connectivity
Assembly : Microsoft.SmartDevice.Connectivity (dans Microsoft.SmartDevice.Connectivity.dll)
Syntaxe
Public Class RemoteAgent
Dim instance As RemoteAgent
public class RemoteAgent
public ref class RemoteAgent
public class RemoteAgent
Notes
Utilisez la méthode Device.GetRemoteAgent pour en obtenir une instance.
Utilisez cette classe pour déployer des agents Smart Device qui échangent des données et/ou effectuent des tâches personnalisées qui ne sont pas disponibles dans FileDeployer, RemoteProcess ou Device. Pour plus d'informations, consultez Contrôle des appareils avec les API de connectivité Smart Device.
