IWMPContentPartner Interface

Note   This section describes functionality designed for use by online stores. Use of this functionality outside the context of an online store is not supported.

The IWMPContentPartner interface provides methods that Windows Media Player calls to integrate its user interface with an online store's catalog and services. This interface is implemented by a content partner plug-in, which is provided by the online store. Windows Media Player retrieves a pointer to this interface by calling QueryInterface through a pointer to an IWMPSubscriptionService interface.

In addition to the methods inherited from IUnknown, the IWMPContentPartner interface exposes the following methods.
