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

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 IWMSBoundIPAddressesIWMSBoundIPAddresses 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

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:
    // TODO: Release temporary COM objects and uninitialize COM.
