IWMSCPPluginAdmin Interface

You can use the IWMSCPPluginAdmin interface to manage control protocol plug-ins. Windows Media Services includes the following system plug-ins for control protocols:

• WMS HTTP Server Control Protocol
• WMS MMS Server Control Protocol
• WMS RTSP Server Control Protocol
• Note   In Windows Server 2008 operating systems, the MMS protocol is not supported, and Windows Media Services does not provide an MMS Server Control Protocol plug-in.

In addition to the methods inherited from IDispatch, the IWMSCPPluginAdmin interface exposes the following methods.

Method	Description
get_BoundIPAddresses	Retrieves an IWMSBoundIPAddresses interface containing a list of bound IP addresses.
get_ControlProtocol	Retrieves the protocol name.
get_ListenAllIPAddresses	Retrieves a Boolean value indicating whether the server must monitor all IP addresses for incoming client requests.
get_Port	Retrieves the port number used by the protocol.
put_ListenAllIPAddresses	Specifies a Boolean value indicating whether the server must monitor all IP addresses for incoming client requests.
put_Port	Specifies the port number used by the protocol.

Example Code

The following example illustrates how to retrieve a pointer to an IWMSCPPluginAdmin interface.

#include <windows.h>
#include <atlbase.h>    // Includes CComVariant.

// To access system plug-in interfaces, the
// entire type library must be imported as shown.
#import "WMSServerTypeLib.dll" no_namespace named_guids \
                               raw_interfaces_only

// Declare variables and interfaces.
IWMSServer              *pServer;
IWMSPlugins             *pPlugins;
IWMSPlugin              *pPlugin;
IDispatch               *pDispatch;
IWMSCPPluginAdmin       *pCPAdmin;

HRESULT         hr;
CComVariant     varIndex;

// Initialize the COM library and retrieve a pointer
// to an IWMSServer interface.
hr = CoInitialize(NULL);
hr = CoCreateInstance(CLSID_WMSServer,
                      NULL,
                      CLSCTX_ALL,
                      IID_IWMSServer,
                      (void **)&pServer);
if (FAILED(hr)) goto EXIT;

// Retrieve a pointer to an IWMSPlugins interface
// containing control protocol plug-ins.
hr = pServer->get_ControlProtocols(&pPlugins);
if (FAILED(hr)) goto EXIT;

// Retrieve a pointer to the IWMSPlugin interface
// of the plug-in to be configured.
varIndex = "WMS RTSP Server Control Protocol";
hr = pPlugins->get_Item(varIndex, &pPlugin);
if (FAILED(hr)) goto EXIT;

// Retrieve a pointer to the custom interface
// of the plug-in.
hr = pPlugin->get_CustomInterface(&pDispatch);
if (FAILED(hr)) goto EXIT;

// Query the specific administration interface
// for the plug-in.
hr = pDispatch->QueryInterface(IID_IWMSCPPluginAdmin,
                              (void **)&pCPAdmin);
if (FAILED(hr)) goto EXIT;

EXIT:
