Here is an example that might help...


---------------
include win32lib.ew
-- progress bar styles
constant
    PBS_SMOOTH          = 1,
    PBS_VERTICAL        = 4

without warning
  constant
      Win   = createEx(Window,"Timer Window",0,Default,Default,200,100,0,0),
      Gauge = createEx(LText,"", Win, 5, 5, 180, 20, 0, 0),
      PBar  = createEx(ProgressBar,"",Win,5,40,180,20,PBS_SMOOTH,0),
      Timer = 1

  procedure tick( integer self, integer event, sequence parms )
      -- advance the progress bar by 5 ticks
      integer curpos
      sequence currange

      -- Get the allowable range of values
      currange = getScrollRange( PBar )
      -- Get the current position
      curpos = getScrollPos( PBar )

      -- Move to the next position, if it is beyond the
      -- end of the bar, reset it.
      curpos += 5
      if curpos > currange[2] then
        curpos = 0
      end if

      -- Show the new position
      setScrollPos( PBar,  curpos )
      -- Update the digital display too.
      setText(Gauge, sprintf("%d%% (%d)",
                     {floor(100*curpos/currange[2]),curpos}))

  end procedure
  setHandler(Win, w32HTimer, routine_id( "tick" ))

  -- Set the max range for the bar
  setScrollRange(PBar, 0, 60)

  -- tick once per second
  setTimer( Win, Timer, 1000 )

  WinMain( Win, Normal )
