Microsoft.SmartDevice.DeviceAgentTransport (Espacio de nombres)

Actualización: noviembre 2007

Este espacio de nombres contiene tipos que conforman el componente correspondiente al dispositivo de la API de conectividad de dispositivos Smart Device. Las aplicaciones de Smart Device administradas que hacen referencia y utilizan este espacio de nombres se denominan aplicaciones de agente de dispositivo. Las aplicaciones de escritorio que utilizan la API de conectividad de dispositivos Smart Device pueden implementar agentes de dispositivos en el dispositivo y comunicar con ellos intercambiando datos del paquete. Con esta biblioteca, puede intercambiar datos entre el dispositivo y el escritorio mediante programación, a la vez que permite que la API de conectividad de dispositivos Smart Device controle los detalles de los mecanismos de transporte y la interconectividad de los dispositivos.

Para utilizar Microsoft.SmartDevice.DeviceAgentTransport en el proyecto de Smart Device, complete las siguientes tareas:

  • En el proyecto de Smart Device, agregue una referencia al ensamblado Microsoft.Smartdevice.DeviceAgentTransport.dll (unidad de disco:\Archivos de programa\Archivos comunes\Microsoft Shared\CoreCon\1.0\Target\Microsoft.Smartdevice.DeviceAgentTransport.dll).

  • Implemente la biblioteca DeviceAgentTransport.dll nativa (unidad de disco:\Archivos de programa\Archivos comunes\Microsoft Shared\CoreCon\1.0\Target\wce400\cpu\DeviceAgentTransport.dll) y el ensamblado Microsoft.Smartdevice.DeviceAgentTransport.dll administrado en el Smart Device.

Para obtener más información, vea Controlar dispositivos con la API de conectividad de dispositivos inteligentes y Tutorial: Intercambiar datos entre aplicaciones de escritorio y de dispositivos.

Nota:

Para crear un agente de dispositivos mediante Visual C++, use API de conectividad de dispositivos inteligentes en dispositivos no administrados.
