vc2010学生信息管理系统

以下是 VC2010 学生信息管理系统的简单实现：

1. 创建一个 Windows 窗口应用程序，命名为 StudentInfoManagementSystem。

2. 在窗口上添加以下控件：

- 静态文本控件 x5，用于显示“姓名”、“学号”、“数学”、“英语”、“计算机”等信息；
- 编辑框控件 x4，用于输入姓名、学号、数学成绩、英语成绩和计算机成绩；
- 按钮控件 x5，用于添加、删除、修改、查询和退出操作；
- 列表框控件，用于显示学生信息。

3. 双击每个按钮控件，在相应的按钮事件处理函数中添加以下代码：

- 添加操作：读取编辑框中的学生信息，将其添加到列表框中；
- 删除操作：删除列表框中选中的学生信息；
- 修改操作：修改列表框中选中的学生信息；
- 查询操作：在列表框中查找指定学生信息并选中；
- 退出操作：关闭窗口。

4. 在窗口应用程序的资源文件中添加菜单资源，用于打开和保存学生信息。

5. 在程序中添加相应菜单事件处理函数，用于打开和保存学生信息。

6. 编写相应的文件读写函数，用于将学生信息保存到文件中和从文件中读取学生信息。

7. 最后，编译并运行程序，测试其功能是否正常。

由于代码过长，这里无法全部展示。您可以参考以下代码示例：

#include <Windows.h>
#include <CommCtrl.h>

#define ID_EDIT_NAME 1001 // 姓名编辑框
#define ID_EDIT_ID 1002 // 学号编辑框
#define ID_EDIT_MATH 1003 // 数学成绩编辑框
#define ID_EDIT_ENGLISH 1004 // 英语成绩编辑框
#define ID_EDIT_COMPUTER 1005 // 计算机成绩编辑框
#define ID_BUTTON_ADD 101 // 添加按钮
#define ID_BUTTON_DELETE 102 // 删除按钮
#define ID_BUTTON_MODIFY 103 // 修改按钮
#define ID_BUTTON_QUERY 104 // 查询按钮
#define ID_BUTTON_EXIT 105 // 退出按钮
#define ID_LIST_STUDENT 200 // 学生信息列表框
#define ID_MENU_OPEN 300 // 打开菜单
#define ID_MENU_SAVE 301 // 保存菜单
