The OnStartPushing method is called by a plug-in to respond when the server calls IWMSPushSource.StartPushing.
void IWMSPushSourceCallback.OnStartPushing( int hr, ulong qwContext );
int indicating whether the call to IWMSPushSource.StartPushing was successful.
ulong containing a value defined by the server to identify which call to IWMSPushSource.StartPushing the plug-in is responding to when it calls OnStartPushing. You must pass this value back unaltered.
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.
