From: David Webber on 15 Jan 2010 14:26 Thanks again everyone for the various replies. CStdioFileEx looks good and I plan to explore the other one too. For the moment, I know the lines in the files I'm interested in have a finite maximum length, and I have adopted the quick and dirty solution, which, for the record, is: FILE *fp = _wfopen( pszFilePath, L"rt, ccs=UNICODE" ); wchar_t szBuffer[512]; and then fgetws( szBuffer, 511, fp ); until finished. Not for C++ purists, I know <vbg>, but opening the file in this mode reads and ANSI file if there's no BOM and a UTF-16LE file if the appropriate BOM is there. This is sufficient for my current purposes. Dave -- David Webber Mozart Music Software http://www.mozart.co.uk For discussion and support see http://www.mozart.co.uk/mozartists/mailinglist.htm

This is sufficient for my current purposes. The C++ I/O stream library is very slow if compared to both CRT (that you are using) and of course Win32 memory mapped files. I see nothing wrong in using C FILE* instead of C++ I/O streams in C++ code: just use the right tool for the job :) Giovanni

I say, whatever works for you and keeps you using MFC ... works for me :o) Tom "David Webber" <dave(a)musical-dot-demon-dot-co.uk> wrote in message news:exQ4OjhlKHA.1824(a)TK2MSFTNGP04.phx.gbl... > Thanks again everyone for the various replies. > > CStdioFileEx looks good and I plan to explore the other one too.
