IWMSDataSourcePluginCallback.OnGetDataContainerVersion (C#)

The OnGetDataContainerVersion method is called by a data source plug-in to respond when the server calls IWMSDataSourcePlugin.GetDataContainerVersion.

Syntax

Parameters

hr

int containing the result of the call to IWMSDataSourcePlugin.GetDataContainerVersion.

pVersion

IWMSDataContainerVersion object created when the plug-in implemented IWMSDataSourcePlugin.GetDataContainerVersion.

qwContext

ulong containing a value defined by the server to identify which IWMSDataSourcePlugin.GetDataContainerVersion request the plug-in is responding to when it calls OnGetDataContainerVersion. The plug-in 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.
