 The TBM_SETRANGE message should be sent from ::Init() method.
 Dialog creation differs from the window's, it doesn't call the
 InitTrackBar() function, using the template technique instead.

 The doc says that a trackbar sends the notification message not with
 the usual WM_NOTIFY, but with the WM_HSCROLL and WM_VSCROLL, so it is
 needed to add these messages handling in window and dialog processing
 procedures.
