Is there any way of checking if a file is already open, to prevent me
calling close on it twice.

like a rewind , or something . if the operation
succeeds , then , viola' , the file's open ...

Compare m_hFile against CFile::hFileNull. Remember, when your CFile object
goes out of scope, the file will get closed automatically.

I have discovered that the auto closure of the file appears to occur in a
seperate thread that MFC runs at low priority. If you need to guarantee a
file is closed, wrap the CFile::Close() method in a try/catch and ignore the
error that says the file wasn't open.
