Windows Media Player 11 SDK Implementing CSearch 

Implementing CSearch

The IWMPPluginUI interface has several methods that are called by Windows Media Player at different times during the life cycle of a plug-in instance. The wizard provides basic implementations of these methods as well as the class constructor and destructor and other class methods. The Search.h file must be modified so that Windows Media Player can communicate with the UI, which is described in the next section.

In order for the CPluginWindow class to have access to the private member variable m_spCore, a friend class declaration must be made inside the CSearch class definition as shown in the following code snippet:

class ATL_NO_VTABLE CSearch : 
    public CComObjectRootEx<CComSingleThreadModel>,
    public CComCoClass<CSearch, &CLSID_Search>,
    public IWMPPluginUI
{

friend class CPluginWindow;

// Rest of class definition...

}
