Non-editable fields don't use handles because their contents aren't expected
to change. Therefore, the system just uses a text pointer. To update a
non-editable field, allocate and lock memory for your results, then use
FldSetTextPtr(). You do need to make sure that memory is valid until you
either close the form or change the pointer again with another call to
FldSetTextPtr().
