壹：讓程序隨系統自啟動應該就不用說了吧，簡單
二：關機記錄時間可以在本程序的unload模塊中寫下記錄過程，即 時間變量=time 即可，當然還要同時保存到某個文件或註冊表的三個固定容器中，保存時註意三個位置的替換即可（刪除第壹個時間、將第二個移到第壹個、第三個移到第二個、將本次記錄的時間寫到第三個位置）。
三：啟動程序顯示前三次關機時間也非常簡單，顯示時就將三個顯示控件的caption等於上面第二條的這三個時間即可。
明白了嗎，妳這個代碼實現起來確是非常簡單的，壹點都不難哦。
代碼如下，自己註意安排控件哦在默認form1窗體上加載Label1(0)、Label1(1)、Label1(2)、text1(0)、text1(1)、text1(2)、text2 、timer1
