1、学生信息管理系统VB河北联合大学 软件设计基础 课程设计报告 设计名称： 学生信息管理系统 姓 名： 学 号： 专业班级： 学 院： 设计时间： 设计地点： 学校机房 指导教师评语： 成绩： 指导教师签字： 年 月 日 软件设计基础课程设计报告 第 2 页，共 25 页 目 录 1.课程设计目的 2.课程设计任务与要求 3.课程设计说明书 4.课程设计成果 5.程序调试过程 6.设计问题的不足和改进方案 7.课程设计心得 8.附录 9.参考文献 软件设计基础课程设计报告 第 3 页，共 25 页 1课程设计目的 软件设计基础课程设计是这门课程的实践性教学环节之一，本次设计结合实际应用的要求，使

2、课程设计既覆盖VB的知识点，又接近工程实际需要。目的是通过课程设计的综合训练，培养学生实际分析问题、解决问题的能力，以及编程和动手能力，最终目标是通过课程设计这种形式，帮助学生系统掌握VB这门课程的主要内容，养成良好的编程习惯，更好的完成教学任务。 2课程设计任务与要求： 要求： 本次课程设计利用软件设计基础课程中所学到的编程知识和编程技巧，完成具有一定难度和工作量的程序设计题目，帮助学生掌握编程、调试的基本技能，独立完成所布置的任务。 要求： 1、对系统进行功能需求分析 2、设计合理的数据结构和系统框架 3、界面设计美观、清楚、合理 4、编程简练，程序功能齐全，能正确运行 5、具有一定的创新

3、性 6、说明书、流程图要清楚 7、课题完成后必须按要求提交课程设计报告 任务： 一.目的： 培养学生综合利用VB语言进行程序设计的能力，主要是培养学生利用系统提供的基本控件、动态数组、文件以及程序结构进行创新性设计。 二.基本要求： 1.要求用随机文件、MSFlexGrid控件、DTPicker控件和动态数组来完成程序的设计。 2. 完成的程序界面要美观，能够完成游戏的整个过程。 三.创新要求： 在基本要求达到后，进行创新设计，如用户权限。 软件设计基础课程设计报告 第 4 页，共 25 页 3课程设计说明书 功能描述： 1.学生信息保存在随机访问文件data.dat中，运行程序时，自动列出数

4、据文件data.dat中保存的所有学生信息。 2. 使用鼠标单击表格的某一单元格，该单元格突出显示，所在行为当前行。单击工具栏上的“插入”按钮，在当前位置上插入一个新空行，单击“追加”按钮在表格最后添加一个空行。使用“删除”按钮可以删除当前行。 3.无论是空格还是已有数据的格，都可以对其中的数据进行直接编辑。对对于学号、姓名和高考分数三列数据使用文本框进行编辑；对于出生日期使用DTPicker控件进行编辑；对于性别、民族、院系、专业和省份等五列数据，使用组合框控件编辑。对数据进行编辑之后，单击“保存”按钮将编辑后的结果保存到data.dat文件中。 4.选择“查询”按扭，弹出“查询”对话框。在

5、“查询”对话框中设置查询条件，“学号”和“姓名”可以输入完整的学号和姓名，也可以输入部分学号和姓名；“出生日期”和“高考分数”中可输入分数和日期范围，其中日期的输入要求使用DTPicker控件。 5.如果用户对数据进行了修改，关闭程序时弹出“退出”对话框。 概要设计 主要写模块说明，模块结构图，系统流程图 模块结构图： 根据功能分析，建立系统的体系结构，即将整个系统分解成若干子模块，用框图表示各功能模块之间的接口关系。 输入登陆信息 验证信息 错正误确 进入系统 提示登录警告 执行操作 简易文件系统功能框图 软件设计基础课程设计报告 第 5 页，共 25 页 详细设计 总体流程图： 各功能模块
