Client Interfaces

Applications use the methods supported by the following interfaces to perform operations on portable devices. These operations include opening a connection to a device, retrieving data from a device, writing data to a device, and so on.

Interface	Description
IEnumPortableDeviceObjectIDs	Enumerates the objects on a portable device.
IPortableDevice	Provides low-level access to a portable device.
IPortableDeviceCapabilities	Retrieves a variety of device capabilities, including supported formats, commands, and functional objects.
IPortableDeviceContent	Provides methods to create, enumerate, and delete content on a device.
IPortableDeviceDataStream	Exposes additional methods on an IStream used for data transfers.
IPortableDeviceEventCallback	Implemented by the application to receive asynchronous callbacks.
IPortableDeviceManager	Enumerates devices that are connected to the computer, and provides a simple way to request installation information for the device (including manufacturer, friendly name, and description).
IPortableDeviceProperties	Read and write properties for an object on the device.
IPortableDevicePropertiesBulk	Reads and writes multiple properties on multiple objects on a device, asynchronously.
IPortableDevicePropertiesBulkCallback	Implemented by the application to track the progress of an asynchronous operation that was begun by using the IPortableDevicePropertiesBulk interface.
IPortableDeviceResources	Provides access to an object's data.
IPortableDeviceService	Windows 7 only. Provides low-level access to a portable device service.
IPortableDeviceServiceCapabilities	Windows 7 only. Retrieves a variety of service capabilities, including supported formats, commands, methods, and rendering profiles.
IPortableDeviceServiceMethods	Windows 7 only. Invokes methods synchronously and asynchronously on a service.
IPortableDeviceServiceMethodCallback	Windows 7 only. Implemented by the application to track the completion of an asynchronous service method operation begun by calling IPortableDeviceServiceMethods::InvokeAsync
IPortableDeviceServiceManager	Windows 7 only. Enumerates services that are supported by a device, and retrieves the device associated with a service.

 

The following diagram shows how an application gets most of the interfaces it needs. Not all methods of all the interfaces or the interfaces that are implemented by the application are shown.
