>If I open a file on the server using ODBC, how do I get the API handle? I would like to set the API flag FILE_FLAG_WRITE_THROUGH on my files after I open them. Any idea how to do this, or am I going about this the wrong way? Thanks.

>I don't think you can, since you don't have direct control over the low-level file I/O mechanism via ODBC - the file handle isn't exposed through the ODBC driver AFAIK.
