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); } }
