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 路基工程安全技术交底工程项目施工成本控制工程量增项单年度零星工程技术标正投影法基本原理 ,不妨命名为screen_saver。 (2)现在我们来 设计 领导形象设计圆作业设计ao工艺污水处理厂设计附属工程施工组织设计清扫机器人结构设计 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;
