MFC应用程序设计中的常用控件(共15页).doc

精选优质文档-倾情为你奉上安康学院电子与信息工程学院实验报告课程名称VC+高级编程实验名称MFC应用程序设计中的常用控件（一）日期2018.5.29成绩姓名杨旋学号班级15级计本1班一、实验目的：掌握利用MFC进行Windows应用程序设计时，常用控件的基本方法。二、实验题目内容及要求：1. 编写一个用于进行成绩计算的程序。具体要求如下：界面中显示五个裁判所给出的等级制成绩（每个裁判利用一组单选按钮进行打分，成绩分为“优秀”、“良好”、“中等”、“及格”、“不及格”的档次），单击界面中的“计算”按钮之后，计算出百分制的平均成绩显示在界面中的一个文本框中，在计算时，每个档次的成绩对应的百分制成绩为：“优秀”95分“良好”85分“中等”75分“及格”65分“不及格”45分要求程序的运行界面自主设计，在完成上述基本功能前提下，可以进一步进行功能扩展。代码专心-专注-专业#include "stdafx.h"#include "MFCApplication4.h"#include "MFCApplication4Dlg.h"#include "afxdialogex.h"#ifdef _DEBUG#define new DEBUG_NEW#endifclass CAboutDlg : public CDialogExpublic:CAboutDlg();#ifdef AFX_DESIGN_TIMEenum IDD = IDD_ABOUTBOX ;#endifprotected:virtual void DoDataExchange(CDataExchange* pDX);
