IWMSBoundIPAddresses Interface
The IWMSBoundIPAddresses interface contains a collection of BSTR values used by control protocol plug-ins to bind certain protocols, such as HTTP, to specific IP addresses. It is exposed by the following system plug-ins:
WMS HTTP Server Control Protocol plug-in
WMS MMS Server Control Protocol plug-in
WMS RTSP Server Control Protocol plug-in
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 IWMSBoundIPAddresses interface exposes the following methods.
Method |
Description |
|---|---|
Add |
Adds a new IP address string to the IWMSBoundIPAddresses collection. |
get_Count |
Retrieves the number of IP addresses in the IWMSBoundIPAddresses collection. |
get_Item |
Retrieves a specific IP address from the IWMSBoundIPAddresses collection. |
get_length |
Retrieves the number of IP addresses in the IWMSBoundIPAddresses collection. This method is included for JScript compatibility. |
RemoveAll |
Removes all IP addresses from the collection. |
Example
The following example illustrates how to retrieve a pointer to an IWMSBoundIPAddresses 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;
IWMSBoundIPAddresses *pBoundIPAddresses;
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;
// Retrieve a pointer to the list of bound
// IP addresses.
hr = pCPAdmin->get_BoundIPAddresses(&pBoundIPAddresses);
if (FAILED(hr)) goto EXIT;
EXIT:
// TODO: Release temporary COM objects and uninitialize COM.
