請問，要如何用Undo 還原5次Edit 修改的內容

Ctrl-Z inside IDE? If you mean to undo inside a standard TEdit, you can only undo ONE level. For multiple level undo, you need to implement it yourself or try some 3rd party tools.

參考這個範例吧! http://vip.6to23.com/aizb/docu/mynote.zip 網路志工聯盟----Visita網站http://www.vista.org.tw ---[ 發問前請先找找舊文章 ]---

還是不太懂耶~~~ 只要用一個 TEdit 和 一個 Button 按下Button會 Undo 還原修改 TEdit的內容~~而且它能還原之前修改5次的內容 要如何用呢....

Some sugguestion: 1) store any changes to a StringList in the OnKeyPress event (i.e. trim(Edit1.Text Key)) 2) undo is resotring the text stored in the StringList, delete it from the list afterwards
