IWMSDataContainerCallback.OnWrite (Visual Basic .NET)
The OnWrite method returns the results of the IWMSDataContainer.Write method call.
Syntax
Parameters
hr
Int32 containing the result of the call to IWMSDataContainer.Write.
dwActualBytesTransferred
UInt32 containing the actual amount, in bytes, of data transferred.
qwContext
UInt64 containing a value defined by the server to identify which IWMSDataContainer.Write request the plug-in is responding to when it calls OnWrite. 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.
