VC++实训--学生信息管理系统

1、信息科学与工程学院报告书专 业：计算机科学与技术课程 名称：VC+实训题 目：学生信息管理系统班 级：设 计 者：完 成 时 间：总 成 绩教师签名学生信息管理系统一 系统总体方案系统基本实现了对学生信息的查询，添加，修改，删除，保存功能。二 设计思路和主要步骤思路主要是设计一个单文档用来实现主界面，然后在菜单栏添加一个菜单项，下面包含录入学生基本信息，查询学生基本信息，和修改学生基本信息等多项子菜单，每项子菜单都对应一个对话框对数据进行处理。在主对话框中添加列表控件用来显示学生的基本信息，以方便学生信息的修改，具体修改哪一项。对于学生信息的录入，查询，修改，删除都用按钮控件，并为每个按钮添加

2、消息响应函数用来处理学生的信息操作。接下来就是要把学生的基本信息能够保存下来，因此要用到文件的操作，fstream可以满足要求。综上所述，必须先掌握按钮控件，列表控件，新对话框的构建，编辑控件和消息的响应与处理原理！三 各功能模块和流程图1.功能模块实现 主界面 对话框一 对话框2 对话框3四 设计代码1.主体框架代码：int CMainFrame:OnCreate(LPCREATESTRUCT lpCreateStruct)if (CFrameWnd:OnCreate(lpCreateStruct) = -1)return -1;if (!m_wndToolBar.CreateEx(this
