[Ace-users] Access MFC's progress bar from multithreads, any suggestion?

VERSION : 5.6.2
HOST X86,Windows XP SP2
Compiler: Visual studio 2003

In my app,  handle_events is called from multithreads. I want to
refresh MFC's progress bar from handle_inputs. When compiling ACE, I
set the flag ACE_HAS_MFC=1, so is it safely to access the process bar
from multithreads ?
if not, how? any suggestion is welcome, thanks!
