本系统有三种操作权限，其中，营业员只可以执行开台、点菜、买单及查询日收入操作；领班可以执行开台、点菜、买单、进货、添加新员工、日收入及月收入查询等操作；经理具有最高权限，除了领班及营业员的操作权限外，还可以设置员工权限、添加商品信息及菜式信息、备份与恢复数据库及初始化数据等操作。(The system has three operating authority, which can only be executed Founding salesperson, a la carte, pay and check daily revenue operations foreman can perform Founding, a la carte, pay, purchase, adding new employees, daily income and monthly income of inquiry operation manager with the highest authority, in addition to the foreman and the operating authority salesperson, you can also set permissions for employees, product information and dishes to add information, database backup and recovery, and initial data and other operations.)

能在MFC界面绘制随着鼠标移动的线条，在visual studio中正常显示(In MFC interface as the mouse moves the lines, the visual studio to the normal display)

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.)

说明：  该系统是一个请求页式存储管理系统，采用FIFO等页面淘汰算法(This system is a requested page storage management system, using FIFO and other pages out algorithm)

用指向指针的指针的方法对5个字符串排序并输出。(With a pointer to a pointer to a string sort method 5 and the output.)

在工业控制软件中经常要显示测量数据，如果在在界面上单纯显示一些数字会显得很单调，如果能在软件中添加色泽艳丽的控件，就一定会为你的软件增色不少，让人有爽心悦目的感觉。在此就介绍一款这样的仪表控件。 (in industrial control software often measured data to show that, if the interface simple figures show was very dull, and if the software can add color sensational control, we would be the software for your occasion gives Shuangxin pleasant feeling. In one such briefing on the dashboard controls.)
