26 * - ES_NUMBER (new since win95)
28 * -!ES_AUTOVSCROLL (every multi line control *is* auto vscroll)
29 * -!ES_AUTOHSCROLL (every single line control *is* auto hscroll)
31 * When there is no autoscrolling, the control should first check whether
32 * the new text would fit. If not, an EN_MAXTEXT should be sent.
33 * However, currently this would require the actual change to be made,
34 * then call EDIT_BuildLineDefs() and then find out that the new text doesn't
35 * fit. After all this, things should be put back in the state before the
36 * changes. Note that for multi line controls !ES_AUTOHSCROLL works : wordwrap.
