IWMSPublishingPoint Interface

Article
09/04/2009

The IWMSPublishingPoint interface supports the basic properties that describe both on-demand and broadcast publishing points. Additional properties and methods supported by on-demand and broadcast publishing points are available through the IWMSOnDemandPublishingPoint and IWMSBroadcastPublishingPoint interfaces. These interfaces can be accessed by calling QueryInterface on the IWMSPublishingPoint interface.

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

Method	Description
get_AllowClientsToConnect	Retrieves a Boolean value that indicates whether the publishing point can receive client connections.
get_AllowPlayerSideDiskCaching	Retrieves a Boolean value that indicates whether the publishing point allows clients to cache content locally.
get_Authenticators	Retrieves an IWMSPluginsIWMSPlugins Interface that contains a collection of authentication plug-ins.
get_CacheProxyExpiration	Retrieves the expiration value for cached content.
get_CurrentCounters	Retrieves an IWMSPublishingPointCurrentCountersIWMSPublishingPointCurrentCounters Interface that contains counters that are maintained by the publishing point.
get_DistributionUserName	Retrieves the user name that is provided by the client in response to an authentication challenge sent during server-to-server distribution.
get_EnableFEC	Retrieves a value that indicates whether Forward Error Correction is enabled.
get_EnableWrapperPath	Retrieves a Boolean value that indicates whether a wrapper playlist is enabled for the publishing point.
get_EventHandlers	Retrieves an IWMSPlugins interface that contains a collection of event authorization and notification plug-ins.
get_FileDescriptions	Retrieves an IWMSFileDescriptions collection that contains information about files, directories, and playlists in a specified publishing point path.
get_ID	Retrieves a unique CLSID for the publishing point.
get_IsDistributionPasswordSet	Retrieves a VARIANT_BOOL that indicates whether the password that is returned in response to an authentication challenge during server-to-server distribution is set.
get_Limits	Retrieves an IWMSPublishingPointLimitsIWMSPublishingPointLimits Interface that contains information about limits maintained by the publishing point.
get_MonikerName	Retrieves the moniker name for a publishing point.
get_Name	Retrieves the name of the publishing point.
get_OutgoingDistributionConnections	Retrieves an IWMSOutgoingDistributionConnections collection that contains information about distribution connections.
get_Path	Retrieves the path to the publishing point content.
get_PeakCounters	Retrieves an IWMSPublishingPointPeakCountersIWMSPublishingPointPeakCounters Interface that contains information about peak counters maintained by the publishing point.
get_Players	Retrieves an IWMSPlayersIWMSPlayers Interface that contains information about connected players.
get_Properties	Retrieves an IWMSNamedValuesIWMSNamedValues Interface that contains a collection of name/value pairs for the publishing point.
get_Status	Retrieves the publishing point status.
get_StreamFilters	Reserved for future use.
get_TotalCounters	Retrieves an IWMSPublishingPointTotalCountersIWMSPublishingPointTotalCounters Interface that contains information about the total counters maintained by the publishing point.
get_Type	Retrieves an enumeration value that indicates the publishing point type.
get_WrapperPath	Retrieves the path to a wrapper playlist file.
put_AllowClientsToConnect	Specifies a Boolean value that indicates whether the publishing point can receive client connections.
put_AllowPlayerSideDiskCaching	Specifies a Boolean value that indicates whether the publishing point allows clients to cache content locally.
put_CacheProxyExpiration	Specifies the expiration value for cached content.
put_EnableFEC	Specifies whether to enable Forward Error Correction (FEC).
put_EnableWrapperPath	Specifies a Boolean value that indicates whether a wrapper playlist is enabled for the publishing point.
put_Name	Specifies the name of the publishing point.
put_Path	Specifies the path to the publishing point content.
put_WrapperPath	Specifies the path to a wrapper playlist file.
SetDistributionUserNamePassword	Specifies the password and user name to use in response to an authentication challenge sent during server-to-server distribution.

Example

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

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

// Declare variables and interfaces.
IWMSServer                  *pServer;
IWMSPublishingPoints        *pPubPoints;
IWMSPublishingPoint         *pPubPoint;

HRESULT         hr;
CComVariant     varIndex;
long            lCount;

// 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 the IWMSPublishingPoints interface
// and retrieve the total count of publishing points.
hr = pServer->get_PublishingPoints(&pPubPoints);
if (FAILED(hr)) goto EXIT;
hr = pPubPoints->get_Count(&lCount);
if (FAILED(hr)) goto EXIT;

// Retrieve information about each publishing point.
for (long x = 0; x < lCount; x++)
{
    varIndex = x;
    hr = pPubPoints->get_Item(varIndex, &pPubPoint);
    if (FAILED(hr)) goto EXIT;

    // Release temporary COM objects.
    pPubPoint->Release();
}

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