Classe RemoteAgent

Aggiornamento: novembre 2007

Utilizzato per distribuire le applicazioni agente di dispositivo al dispositivo e scambiare dati tra il computer desktop e Smart Device.

Spazio dei nomi:  Microsoft.SmartDevice.Connectivity
Assembly:  Microsoft.SmartDevice.Connectivity (in Microsoft.SmartDevice.Connectivity.dll)

Sintassi

Public Class RemoteAgent

Dim instance As RemoteAgent
public class RemoteAgent
public ref class RemoteAgent
public class RemoteAgent

Note

Utilizzare il metodo Device.GetRemoteAgent per ottenere un'istanza.

Utilizzare questa classe per distribuire agenti di dispositivo che scambiano dati e/o eseguono attività personalizzate non disponibili in FileDeployer, RemoteProcess o Device. Per ulteriori informazioni, vedere la classe Controllo dei dispositivi mediante l'API di connettività per Smart Device.
