win API之航空客运订票系统（课程设计）

  这学期的数据结构课结了，上个周做了课程设计，在此总结下（晒一下）

  先是老师给了选题，我选了航空客运订票系统这个选题。

  这个系统定义的也很简单，就是两个单链表，一个航班的，一个顾客的，再对它俩进行遍历、增加、查找、删除，来实现订票、取消订票、查询顾客、查询航班。

  可是课程设计为期一个星期，总不能这么就完了吧，这不就啥也没干嘛！      我转念一想，不行！我必须做出和其他人不一样的程序。

  可是栈、图、串在这个项目里好像用不到啊，开始想把单链表换成双链表，但感觉和大家比起来没啥突破。

  最后决定做win32程序。

  由于程序要在xp环境下运行，编译器用vc++6.0。由于编译器过于老旧必须下一个Strsafe相关的头文件以及链接库。

考虑到程序的规模不是很大，就用API来做。下面附上代码。

StdAfx.h头文件（关于数据结构和部分函数的定义）

然后关于资源文件我就简单提一下，有五个对话窗口，一个重绘背景的图，一个图片控件的图，还有一个图标

运行程序

打开DEBUG文件夹下的

进入界面

各功能都测试过，没有问题（前提是订票之前先查看有哪些航班后，在输入航班号的时候千万不要输错，在这点上我做的不太人性化）

关于测试图我就不一一发了，我直接把debug文件夹打包后上传到资源里，感兴趣可以下载下来玩玩。

关于对成果的不足之处：

1.在订票界面，输入航班的编辑框完全可以用一个下拉菜单来代替，毕竟用鼠标来选择当前现有航班就不会出错了。

2.按钮本来想重绘的，每个不同窗口背景也想重绘成不同背景，但是嫌麻烦，就没实现。

3.如果添加一个提示当前时间还有天气的控件能更人性化（嫌麻烦没做.....）

4.如果再添加一个“程序载入中”的模块再添点音效就更好了。

得到的收获：自娱自乐又完成了课程设计，两全其美。
