基于MFC的学生成绩管理系统

1.基本功能演示​

1.1软件登陆界面​

为实现多账户的登陆方式，故采用了标签页组合的方式，每个分页面指向一个登录窗口。​

1.2学生界面​

学生界面所需要的功能为课程分数查询，功能较为简单，采用了下拉框+编辑框+按钮的方式实现，需要的特殊功能为学分预警。当科目分数小于60时，弹出弹框，并提示，当前科目分数小于60，要加油啦。​

1.3教师界面​

教师界面相对于学生界面略显复杂，采用了列表+下拉框+编辑框的方式，首先通过下拉框的方式选择姓名，随之与其对应的其他几项也会出现，可以根据科目下拉框选择需要修改的科目，写好后点击修改​

1.4教务界面​

教务界面相较于教师界面包含了成绩修改的功能，同时增加了对学生的增加​

2.部分代码展示​
