IWMSPlaylistParserCallback.OnWritePlaylist (C#)
The OnWritePlaylist method returns to the server the result of a WritePlaylist call.
void IWMSPlaylistParserCallback.OnWritePlaylist(
int hr,
INSSBuffer pBuffer,
ulong qwContext
);
Arguments
int specifying the results of a WritePlaylist call. |
|
INSSBufferINSSBuffer Object (C#) that contains the written playlist. |
|
ulong containing a value defined by the server to identify which call to WritePlaylist the plug-in is responding to when it calls OnWritePlaylist. You must pass this value back unaltered. |
Return Value
This method does not return a value. If the plug-in uses the IWMSEventLogIWMSEventLog Object (C#) 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
void IWMSPlaylistParser.WritePlaylist(
IXMLDOMDocument pPlaylist,
IWMSPlaylistParserCallback pCallback,
ulong qwContext)
{
try
{
// TODO: Write the playlist.
pCallback.OnWritePlaylist(S_OK, pINSSBuffer, qwContext);
}
catch
{
pCallback.OnWritePlaylist(E_FAIL, pINSSBuffer, qwContext);
}
}
