  string  Name,
  string  Path



[in] string containing the name of a publishing point to be added. The maximum length is 250 characters.


[in] Member of a WMS_PUBLISHING_POINT_CATEGORY enumeration specifying the type of the publishing point. This must be one of the following values. There is no default value.

Value Description
WMS_PUBLISHING_POINT_TYPE_ON_DEMAND Specifies an on-demand publishing point object.
WMS_PUBLISHING_POINT_TYPE_BROADCAST Specifies a broadcast publishing point object.


[in] string containing the path to the content for the publishing point.

Return Values

This method returns an IWMSPublishingPoint object.

If this method fails, it throws an exception.

Number Description
0x80070057 The value specified for Category is invalid or that Path is a zero-length string or NULL.
0xC00D0036L name is already being used by another publishing point.
0xC00D1455L name contains an invalid character. Invalid characters are: & " ' < > \ and the ANSI characters 0-31 and 127.
0xC00D1392L name is longer than the maximum length allowed.


The name of the publishing point must be unique. You can indicate the home publishing point by specifying only the forward slash character (/). There can be only one home publishing point, and it can be either a broadcast or on-demand publishing point. A home publishing point is not mandatory, but it enables clients to connect using the shorter URL formats such as protocol://server_name and protocol://server_name/file_name.

Any other publishing point names must not contain a leading or trailing /, but a / character is permitted in the middle of a name. The following characters are not permitted:

< > \ ? % & '  # { } | ^ [ ] `

White spaces are permitted in the name, but the server will strip leading and trailing white spaces.

The path must start with an appropriate prefix to indicate the data source plug-in to use. The following table illustrates valid paths.

Path Example
Media file file:://C:\wmpub\wmroot\movie.wmv


Playlist file file:://C:\wmpub\wmroot\playlist.wsx


Stream from an encoder https://encoder:port
Stream pushed to an encoder push:*
Content from a publishing point on a local server lpp://pubpoint/media.wmv
Stream from a publishing point on a local or remote server rtsp://server/pubpoint


Stream from a station or publishing point on a version 4.1 server https://server/stationname


Media file or playlist on a local or remote server rtsp://server/pubpoint/movie.wmv
Playlist file from a Web server https://server/playlist.asp


Directory of files file://C:\wmpub\wmroot\directory

When the server is installed, it creates a cache publishing point and a proxy publishing point. You cannot create or delete these.

Example Code

using Microsoft.WindowsMediaServices.Interop;
using System.Runtime.InteropServices;

// Declare variables.
WMSServer              Server;
IWMSPublishingPoints   PubPoints;
IWMSPublishingPoint    PubPoint;

string                 strName;
string                 strPath;

try {
    // Create a new WMSServer object.
    Server = new WMSServerClass();

    // Retrieve the IWMSPublishingPoints object.
    PubPoints = Server.PublishingPoints;

    // Add a new publishing point to the server.
    strName = "New Pub Point";
    strPath = "c:\\wmpub\\wmroot\\";
    PubPoint = PubPoints.Add(strName,
catch (COMException comExc) {
    // TODO: Handle COM exceptions.
catch (Exception e) {
