eric,

it's been a while since i've done this, but wouldn't your code look
something like this:

{
  StDialogHandler outerHandler( whatever... );

  do {
    message = outerHandler.DoDialog();
    if (message == msg_OpenOtherDialog) {
      StDialogHandler innerHandler( whatever... );

      // deal with the inner dialog here...
      message = msg_OK; // or msg_Cancel...whatever...
    }
  } while (message != msg_OK && message != msg_Cancel);
}

you could deal with the inner dialog in an entirely different method
(which is what i would do) but still set the "message" variable for the
outer dialog, after having dealt with the inner dialog, such that you
exit your while loop cleanly.

is that what you're looking for? HTH...
