C语言课程设计 Win32应用程序

问题描述:

请设计一个职工信息管理程序,以方便人事部门对本单位职工的管理,该程序应该具有以下功

能:

(1)能从键盘输入职工的信息 。

(2)给定职工号,显示职工的信息。

(3)给定工作部门,显示该部门的职工信息。

(4)给定职工号,修改职工的信息。

(5)给定职工号,删除职工信息。

题目要求:

(1)按照分析、设计、编码、调试、测试的软件过程完成这个应用程序。

(2)职工信息应该包含职工号、姓名、工作部门、职称、入厂时间、工资。

(3)为程序设计windows 窗口,在该窗口上以按钮的形式为用户提供“菜单”,通过点击各个功

能项对应的按钮完成操作。

输入要求:

(1)用户可以根据需求,选定相应的操作项目。进入每个操作后,通过窗口的文本框,从键盘输

入相应的信息。程序根据用户输入的信息完成相应的处理,实现要求的功能。

(2)能对输入的数据进行简单的校验,例如,入厂时间必须是合法的日期格式,职工号是唯一的

(一个职工号对应一个职工的职工信息)。

输出要求:

(1)应用程序运行后,要在屏幕上显示一个按钮形式的“菜单”。

(2)要求用户输入数据时,给出清晰、明确的提示信息,包括输入的数据内容、格式以及结束方

式等。

(3)在程序完成处理后,要清楚地给出程序的处理结果。例如,在给定职工号删除职工信息时,

如果该职工不存在,要提示没能删除,如果删除成功要提示删除成功。

实现要求:

(1)在程序中使用链表存储职工信息。

(2)采用模块化程序设计的方法,将程序中的各项功能用函数实现。

提示:

(1)使用结构体表示职工信息,一个结点保存一条职工信息。

扩展功能:

(1)提供一些统计功能。例如统计每个部门的人数,统计平均工资、统计各职称的人数。

(2)职工信息从文件读入。

(3)将职工信息保存到文件中。

代码如下:

  1 #include <windows.h>
  2 #include<string.h>
  3 #include<stdio.h>
  4 #include"resource.h"
  5 LRESULT WINAPI WinProc(HWND hWnd,UINT Msg,WPARAM wParam,LPARAM lParam);//函数声明
