Indirectly.  I use the SetProp() function.  Matter of fact, this
is how I store the 'this' of my Dialog base class.  It works well for
me.  Just set the property during the WM_INITDIALOG message.  Then,
when you need those little bytees, call GetProp().  Also, you'll
probably call DialogBoxParam() instead of DialogBox so you can
pass the bytes you need to the WM_INITDIALOG message.
