Hi Sergey,

Is this a fix to a seek offset error or entirely different? I can't picture how this would work in a typical scenario. Let's say I use queries from SQLServer for managing some data, and additionally I have a couple of local dbf tables that remain open throughout the life of the app. How would I get the handle of a table when I open it up initially so that I could use FlushFileBuffers to write the data in the buffers? Am I not understanding and its purpose is entirely different? I guess I'm not clear on when using FlushFileBuffers api is appropriate...


>>Oh, I see. Should closing the file (as we did, in the tests) flush the Windows cache?
