The following code wasted 20 minutes of my time... Find the BUG!

// m_DEBUGFILE is in the class header as a CFile*
m_DEBUGFILE = new CFile();
CFileException fileException;

if ( !m_DEBUGFILE->Open( pszFileName, CFile::modeCreate | CFile::modeNoTruncate |
          CFile::modeReadWrite ), &fileException )
      // fileException.m_cause;
      delete m_DEBUGFILE;
      CString msg = "START DEBUGGING";
      m_DEBUGFILE->Write(msg,  msg.GetLength());
      m_DEBUGFILE->Write("\r\n", 2);

In you if, the default 3rd argument of Open (exception) was set to NULL, and your if was always true, as in

  if (a, b, c)

the condition to be evaluated will be c.

The &fileException should have been in the Open statement,

  m_DEBUGFILE->Open( pszFileName, CFile::modeCreate | CFile::modeNoTruncate | CFile::modeReadWrite, &fileException)

Good replies... and quick too!

Did you look at the sample code from Microsoft?   I always wondered why I can't copy some files ...  maybe microsoft actually based Windows on that sample?

yup, looked at the sample code, the mistake was from the it.
I guess, probably they won't be basing on that code sample? after all, the documentation group is a different group from the coding group (I think).

Lol :)
It seems their sample are specifically written for the doc, as the Open would be always in error!
