Foxtools Editor Support Functions
_EDREDO
_EdRedo() Reverts the last Undo (repeats the action that was cancelled by that Undo) in the editor session passed in <nWHANDL>.
VFP Syntax
= _EdRedo(nWHAND)
Parameters
[in] nWHAND
Fox-window handle of the editor session in question. If nWHANDL is no valid editor-session handle, an error “API call caused an exception” (Error 2028) is raised.
Returns
VOID - no evaluable return value, coz always TRUE.
Remarks
Note: Calling _EdRedo() passing an invalid editor session handle does not cause a General Protection Fault. _EdRedo() may be called more than once in a row to revert more than one Undo. Edit actions that can be undone or reverted (using _EdUndo() and _EdRedo()) may be grouped enclosing them between _EdUndoOn() commands.
VFP Example(s)
Opening an editor session, insert some text, then Undo and Redo changes:
*\\ Open editor session nWHAND =_EDOPENFIL("TEST.TXT", 1) lcText = "NEW TEST" *\\ insert a word = _EDINSERT(m.nWHAND,m.lcText,3) WAIT WINDOW "Press any key to UNDO last insert" = _EDUNDO(m.nWHAND) WAIT WINDOW "Press any key to REDO insert" = _EDREDO(m.nWHAND)
