IWMSPlaylistParserCallback.OnReadPlaylist (C#)

The OnReadPlaylist method returns to the server the result of a ReadPlaylist call.

Syntax

Parameters

hr

int specifying the results of a ReadPlaylist call.

qwContext

ulong containing a value defined by the server to identify which call to IWMSPlaylistParser.ReadPlaylist the plug-in is responding to when it calls OnReadPlaylist. You must pass this value back unaltered.

Return Values

This method does not return a value. If the plug-in uses the IWMSEventLog object to log error information, it is recommended that it send NS_E_PLUGIN_ERROR_REPORTED (0xC00D157D) to the server in the lHr parameter. Typically, the server attempts to make plug-in error information available to the server object model, the Windows Event Viewer, and the troubleshooting list in the details pane of the Windows Media Services MMC. However, if the plug-in uses the IWMSEventLog object to log custom error information to the Windows Event Viewer, sending NS_E_PLUGIN_ERROR_REPORTED stops the server from also logging to the event viewer. For more information about plug-in error information, see Identifying Plug-in Errors.

Remarks

This method is implemented by the server and called by the plug-in.

Example Code

void IWMSPlaylistParser.ReadPlaylist(
    INSSBuffer pBuffer,
    IXMLDOMDocument pPlaylist,
    IWMSPlaylistParserCallback pCallback,
    ulong qwContext)
{
    try
    {
        // TODO: Parse the playlist.

        pCallback.OnReadPlaylist(S_OK, qwContext);
    }
    catch
    {
        pCallback.OnReadPlaylist(E_FAIL, qwContext);
    }
}
