整人VB小程序：蓝屏死机

 

　　本程序启动后，出现蓝屏，模拟蓝屏死机情形。此时，用户无法使用开始菜单、任务管理器，无法操作任何程序，只能干着急。
　　1 秒钟后，在蓝屏的背景上显示：Your Windows is died
　　5 秒钟后，显示：Windows 警告 内存出现严重错误
　　10 秒钟后，显示并计数：警告 硬盘错误，无法正常运行 Windows，Windows 正在试图修复所有错误，请等待 100 秒……
　　25 秒钟后，显示：警告 由于你使用了盗版操作系统 微软惩罚你：定期死机
　　此后，这 4 条信息交替显示

　　结束本程序的方式有两个：
　　1.用鼠标单击屏幕左上角，连续 5 次（左上角 20 个像素范围的区域，大约 1 平方厘米的大小）
　　2.到程序设定的时间后自动结束，默认 120 秒。
　　下面是程序运行截图：

'''以下是窗体代码，在 VB6.0 上调试通过：
'   一、在窗体添加一个控件：Timer1，不必设置任何属性，采用默认属性即可
'   二、在属性窗口将窗体的 BorderStyle 属性设置为 0
