Remarks
Note to OEMs: To enable logging with IGraphBuilder::SetLogFile, you must set SYSGEN_DSHOW_ERRORS when building your platform.
The hFile parameter must be an open file handle. After calling this method with a valid file handle, actions taken by IGraphBuilder methods when attempting to build a filter graph are logged to this file. This is intended to help you determine the cause of any failure to automatically build a filter graph.
Requirements
DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.
