IWMSPlaylistParserCallback.OnReadPlaylist (Visual Basic .NET)

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

IWMSPlaylistParserCallback.OnReadPlaylist(  hr As Int32,
  qwContext As UInt64
)

Arguments

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. 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

Public Sub ReadPlaylist( _
    ByVal pBuffer As INSSBuffer, _

    ByVal qwContext As System.UInt64) _
    Implements IWMSPlaylistParser.ReadPlaylist

        ' TODO: Parse the playlist.

        pCallback.OnReadPlaylist(S_OK, qwContext)
    Catch e As Exception
        pCallback.OnReadPlaylist(E_FAIL, qwContext)
