说明：  vb写的一个小的护眼的定时程序，当启动之后每隔一定时间，会全屏显示指定的图片来让眼睛休息一会，主要用了timer定时器以及一些其他基本控件，实现很简单，由于是作者第一次编写vb程序，命名相对比较随意，没有按照规范来命名
(vb write a small eye timing procedure, when started at a certain time, it will display the specified full-screen picture to let the eye rest, the main use of timer timers and some other basic controls to achieve is very simple, because is the author of the first to write vb program, naming is relatively free, did not follow the norms to name)
