you can use _open file with  _O_APPEND flag
and then use CFile constructor with getted file handle

CFile file(flH);
note that this file will not be closed in the file destructor so

Use CFile::modeNoTruncate (combined with CFile::modeCreate). To append to the end of the file, I think you will have to follow up your CFile::Open() with CFile::SeekToEnd().

I found out a better way to do that. So I just think it's nice to let you know as well


     ofstream outs;"somefile", ios::app);
so ios::app is the append mode:)))
