Hello Yanhong,

That's why I am disturbed that you have a bug database for internal use
only. Microsoft have obviously decided that their time is more important
than that of their customers, as the following case will exemplify:

Last year, I spent a long time trying to solve a problem that some of our
customers reported to us, but which we could not reproduce. After a major
effort, I found it was due to a change to CTime::CTime(const FILETIME&),
which our code did not knowingly call. In fact, it called
CFile::GetFilePath(), which calls CFile::GetStatus(), which calls the CTime
constructor.

It turned out that some network file systems and some CD-ROMs were returning
a file access time of zero. The CTime constructor had been changed to throw
in that circumstance, which was not documented in the MFC 7 release notes.
Our code was not catching it, because the parameterless function
CFile::GetFilePath() did not seem a likely candidate for throwing
E_INVALIDARG. The end result was that our application crashed, and our
customers were not happy.

I carefully documented this bug in a posting to this newsgroup, only to be
immediately informed that it was a known problem! Well, it wasn't fixed in
MFC 7.1, still isn't in the Knowledge Base, and my posting has scrolled off
the end of this NG, so anybody else will also have to find it the hard way.
Is that a reasonable way to treat your customers?

Regards,
Keith MacDonald
