IWMSPlaylistParserPluginCallback.OnCreatePlaylistParser (Visual Basic .NET)
The OnCreatePlaylistParser method is called by the plug-in to report the result of a CreatePlaylistParser callback to server.
IWMSPlaylistParserPluginCallback.OnCreatePlaylistParser( hr As Int32,
pParser As IWMSPlaylistParser,
qwContext As UInt64
)
Arguments
Int32 specifying the result of CreatePlaylistParser call. |
|
IWMSPlaylistParserIWMSPlaylistParser Object (Visual Basic .NET) that was created. |
|
UInt64 containing a value defined by the server to identify which call to IWMSPlaylistParserPlugin.CreatePlaylistParser the plug-in is responding to when it calls OnCreatePlaylistParser. You must pass this value back unaltered. |
Return Value
This method does not return a value. If the plug-in uses the IWMSEventLogIWMSEventLog Object (Visual Basic .NET) 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.
