一、具體實(shí)現(xiàn)步驟:
(1)在Visual Studio.Net下新建一個(gè)C#的Windows應(yīng)用程序工程,不妨命名為screen_saver。
(2)現(xiàn)在我們來(lái)設(shè)計(jì)程序的主界面:
先將窗體的Name屬性設(shè)置為screen、Text屬性設(shè)置為空,BackColor屬性設(shè)置為Black、Size屬性設(shè)置為(800, 600)、 ControlBox、MaximizeBox、MinimizeBox、ShowInTaskbar屬性設(shè)置均為false、FormBorderStyle屬性設(shè)置為None。再往窗體上添加Label控件、PictureBox控件、Timer控件各一個(gè)。將Label控件的Name設(shè)置為word、Text屬性設(shè)置為空;將PictureBox控件的Name設(shè)置為picture1、Image設(shè)置為一個(gè)預(yù)知圖片;將Timer控件的Name設(shè)置為timerSaver、Enabled 屬性設(shè)為true、Interval屬性設(shè)為5。
(3)現(xiàn)在我們開(kāi)始編寫(xiě)完整程序代碼部分:
