用VB语言制作英汉小辞典
上海应用技术学院课程设计任务书
课程名称\x05程序设计基础VB.net课程设计\x05课程代码\x05B704009
设计题目\x05英汉小词典\x05题目序号\x053
设计时间\x052009年6月22日——2009年7月3日
系(院)\x05\x05专业\x05\x05班级\x05
一、课程设计任务(条件)、具体技术参数(指标)
1.所需知识点:
(1)文本文件读写
(2)字符串处理
(3)数组使用
(4)列表框和组合框控件的使用
2.功能要求:
基本要求:设计如图所示的程序界面,左边列表框中的单词表由读取文件英汉词典.txt得到,选择某单词后,会在上面的文本框中显示相应的内容,并且在右边显示相应的中文解释.具有搜索、增加、修改、删除等功能.若做过增加、修改、删除,应对英汉词典.txt做相应的修改.详情参考样例文件.
拓展要求:在文本框中输入单词时,程序会及时地将已输入的字符开头的所有单词显示在列表框中,供用户浏览;优化搜索算法.
二、对课程设计成果的要求(课程设计报告内容)
1.\x05用简练、清晰的语言描述课程设计题目的要求和功能.
2.\x05程序整体结构(模块划分)以及各模块的功能描述.
3.\x05主要模块的算法(用流程图描述).
4.\x05在各模块中,说明使用的变量名及其用途.
5.\x05程序的界面、交互方式和操作方法的说明.
6.\x05报告内容完整、层次清晰,绘制图表规范正确.
7.\x05报告需要交电子版和打印版,源程序交电子版.
