半夜聽到黃家駒的聲音, 忽醒,一身冷汗,哦,原來是電腦忘了關,還在播放Beyond演唱會.於是做了個較簡單的自動關機程式(代碼下載)

(一).說明

       我平時喜歡聽幾首歌再關機睡覺,夏天還好,冬天光著身子去關機要凍個半死 :(,因此為這事做了個最簡單的自動關機程式,讀者如果用得著,就下載用一下吧

最近用這個程式爽多了. 基於以下原因:

       1. 睡覺之前不用顧慮: " 哎呀,電腦還開著,等下還得去關掉"

       2.省電.  一天兩天忘了關機交電費還撐的住,如果長期下去,一大筆電費咋交得起啊.

                    就算有錢也不心甘交這冤枉錢,給鬼聽啊.

        3.夏天跑去關機還好,如果是冬天的話,要凍個半死

        4.恐怖啊! 半夜聽到<黃家駒>的聲音, 忽醒,一身冷汗,原因是電腦忘了關,它還在播放Beyond演唱會

        跟讀者開了些玩笑.  

(二).程式簡單樣本圖

如果您感興趣的話，還可以繼續增加好多功能，比如：重啟機器/待機/睡眠等狀態，還有倒計時功能
