  26. Returns:

  28.  
  29. Comments: 
  30.      The DayFIELD class is used to allow the user to enter PRIMARY or
  31. SECONDARY to
  32. an entry field.  All other values are not allowed or cause the focus to
  33. shift to other windows.  This is done by subclassing the default
  34. WC_ENTRYFIELD window class and only passing the allowed WM_CHAR msgs.
  35. All messages that are meant for the subclassed WC_ENTRYFIELD window are
  36. passed on to it.  All other messages are handled here.
