玻璃之唇结局是什么:用vb,net怎么做屏幕保护程序啊

用Visual C＃编写屏幕保护程序

Visual C#是微软公司推出的新一代程序开发语言，是微软.Net框架中的一个重要组成部分。屏幕保护程序是以scr为扩展名的标准Windows可执行程序。屏幕保护程序不仅可以延长显示器的使用寿命，还可以保护私人信息。本文向大家介绍一个.Net平台上用C#编写的一个动态文本及图形的屏幕保护程序。

一、具体实现步骤：

（1）在Visual Studio.Net下新建一个C＃的Windows应用程序工程，不妨命名为screen_saver。

（2）现在我们来设计程序的主界面：

先将窗体的Name属性设置为screen、Text属性设置为空，BackColor属性设置为Black、Size属性设置为(800, 600)、 ControlBox、MaximizeBox、MinimizeBox、ShowInTaskbar属性设置均为false、FormBorderStyle属性设置为None。再往窗体上添加Label控件、PictureBox控件、Timer控件各一个。将Label控件的Name设置为word、Text属性设置为空；将PictureBox控件的Name设置为picture1、Image设置为一个预知图片；将Timer控件的Name设置为timerSaver、Enabled 属性设为true、Interval属性设为5。

（3）现在我们开始编写完整程序代码部分：

//导入使用到的名称空间

using System.Windows.Forms;

using System.Data;
