Example

The following example illustrates how to retrieve an IWMSBroadcastPublishingPoint object.

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

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

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

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

    // Retrieve each publishing point and retrieve the
    // IWMSBroadcastPublishingPoint object.
    for (int i = 0; i < PubPoints.Count; i++)
    {
        PubPoint = PubPoints[i];

        if (PubPoint.Type == 
            WMS_PUBLISHING_POINT_TYPE.WMS_PUBLISHING_POINT_TYPE_BROADCAST)
        {
            BCPubPoint = (IWMSBroadcastPublishingPoint)PubPoint;
            break;
        }
    }
}
catch (COMException comExc) {
    // TODO: Handle COM exceptions.
