I'm not so sure that the view is worth the climb. First, the user can have the task bar on auto-hide. If so, then centering the form would simply require making the calculation based on the current screen resolution. The function that I presented earlier, can retrieve this information as well.

lnstatus = SHAppBarMessage(4, @lcdata)
IF BITTEST(lnstatus, 0)
  ? "Auto-hide on"
ELSE
  ? "Auto-hide off"
ENDIF
IF BITTEST(lnstatus, 1)
  ? "Always on top on"
ELSE
  ? "Always on top off"
ENDIF

The code I presented earlier should give you what you need.
