说明：  注意更新依赖，winscp上传tmp后安装(Note update dependencies, install after winscp uploads TMP)

以实例为背景学习基于MFC的WINDOWS应用程序设计，编写一个模拟时钟程序，此程序在屏幕左边有一个指针式钟面，右方有两个矩形框，上面以数字方式显示日期和时间，该时间应与指针显示的时间一致，下方的矩形框作为秒表。用菜单选项或按钮设置时间和秒表。时间不必与机器系统时间相同，可任意设置。(Background-instance learning WINDOWS MFC-based application design, the preparation of an analog clock program, this program has a pointer on the screen on the left clock face, on the right there are two rectangular box, above digitally display the date and time, which should be consistent with the pointer display time, and the lower rectangular box as a stopwatch. With a menu option or button to set the time and stopwatch. Time Machine does not have the same system time can be set arbitrarily.)
