  Ehum?

  Are you calling PostMessage overcomplicated and mentioning
  IBindStatusCallback as a counter-example, all in the same breath?

  That's a higher sense of humor.

  Your example of volatile gives little information on how a GUI thread can 
be
  notified of a change to it. You still need to communicate between the
  threads. Atomically changing volatile data has some use, but it's (as you
  sort of mention) limited to lock-free scenarios.

  seems overcomplicated.

  volatile int statusID; // will be enough for current case.

  statusID = STATUS_XXX; // is atomic operation so any lock is not needed

  see also IBindStatusCallback as a good example of how a status info could 
be

  Hello.

  Can you, please, put a piece of code here for example or give me a link
  where to read about that?
  Thanks!
