I am using Visual Studio .NET 2003.
Here is an excerpt from source file appui2.cpp:

case CCommandLineInfo::FileDDE:
m_pCmdInfo = (CCommandLineInfo*)(UINT_PTR)m_nCmdShow;
m_nCmdShow = SW_HIDE;
break;

Now, what is this? m_pCmdInfo gets 0x1, it is an invalid pointer. It makes
my application crash on exit. I had to set m_nCmdShow to 00 to work around
it.

Christopher,

If you build a minimal MFC application to reproduce the problem, does
it cause that to crash in the same way?

I thought this rang a bell, here's an old thread courtesy of Google
groups (watch of for wrapping of the link) ...

But my application should not crash whatever the command line is. Suppose my
client calls it with the /dde switch from the command line or from a desktop
shortcut or from a registry key or whatever; no DDE command follows and the
application crashes on exit. MFC being so buggy, I wonder if it is sane to
use it at all.

BTW This bug came up because MFC 7.1 does not handle DDE commands correctly.
