If I compile the today plug-in along, every thing's fine. If I compile WTL with today plug-in, the today plug-in will disappear in "Start->Setting->Today->Items". I use Dumpbin /exports today.dll to check the interface. InitializeCustomItem & CustomItemOptionsDlgProc are still there.
I think I have fixed this issue to compile the dll using release instead of debug option.
the dll compiled by debug option will depend on msvcr90d.dll. And I think shell32 can not load msvcr90d.dll . That's the reason why the plugin can not display in Today Setting.
