面向程序设计实训报告专 业： 学生姓名： 学 号： 指导教师： 2011年6月 29日面向程序设计实训报告1、实训项目：设计一个基于对话框的计算器，实现常用计算器的基本功能。2、性能、指标、要求；1、基本要求(1) 按照题目要求独立设计计算器所需的所有按钮，并完成程序源码编写、调试及关键代码注释。（2）能够实现+、-、*、/计算。 （3）能够实现对数及幂函数计算。 （4）能够实现三角函数及反三角函数计算。 2、发挥部分 能够实现8，16，10，2进制之间相互转换。 3、方案设计： 方案论证 通过运行VC6.0，用MFC制作windows风格的界面的计算器 工作原理 1、启动VC+6.0, 从File菜单中选择New选项, 选择Projects标签，然后单击MFCAppWizard(exe)。2、在Location域中输入一个合适的路径名或单击Browse按钮来选择一个。在Project name中输入项目名称（比如：0952100407）。点OK。3、打开MFC AppWizard-Step1对话框后。选择基本对话。点下一个 。4、在MFC AppWizard-Step2 of 4对话框。 输入标题对话，如：计算器。点下一个。5、在MFC AppWizard-Step3 of 4对话框。不做任何更改，直接点下一个。6、在MFC AppWizard-Step4 of 4对话框。可以修改分类名等信息，在这里不做任何更改，直接点完成。至此进入了界面设计过程。4、软件设计 进入界面设计界面后，利用右侧的控件栏添加按钮，在按钮属性中修改按键的显示，双击按键进入按键的程序设计。制作完成后的界面如下所示：5、制作与调试过程； 双击按钮后进入程序设计过程，每个按钮的程序如下所示：/ 0952100407Dlg.cpp : implementation file/#include stdafx.h#include 0952100407.h#include 0952100407Dlg.h#include cmath#ifdef _DEBUG#define new DEBUG_NEW#undef THIS_FILEstatic char THIS_FILE = _FILE_;#endif/ CAboutDlg dialog used for App Aboutclass CAboutDlg : public CDialogpublic:CAboutDlg();/ Dialog Data/AFX_DATA(CAboutDlg)enum IDD = IDD_ABOUTBOX ;/AFX_DATA/ ClassWizard generated virtual function overrides/AFX_VIRTUAL(CAboutDlg)protected:virtual void DoDataExchange(CDataExchange* pDX); / DDX/DDV support/AFX_VIRTUAL/ Implementationprotected:/AFX_MSG(CAboutDlg)/AFX_MSGDECLARE_MESSAGE_MAP();CAboutDlg:CAboutDlg() : CDialog(CAboutDlg:IDD)/AFX_DATA_INIT(CAboutDlg)/AFX_DATA_INITvoid CAboutDlg:DoDataExchange(CDataExchange* pDX)CDialog:DoDataExchange(pDX);/AFX_DATA_MAP(CAboutDlg)/AFX_DATA_MAPBEGIN_MESSAGE_MAP(CAboutDlg, CDialog)/AFX_MSG_MAP(CAboutDlg)/ No message handlers/AFX_MSG_MAPEND_MESSAGE_MAP()/ CMy0952100407Dlg dialogCMy0952100407Dlg:CMy0952100407Dlg(CWnd* pParent /*=NULL*/): CDialog(CMy0952100407Dlg:IDD, pParent)/AFX_DATA_INIT(CMy0952100407Dlg)m_EDIT = _T();/AFX_DATA_INIT/ Note that LoadIcon does not require a subsequent DestroyIcon in Win32m_hIcon = AfxGetApp()-LoadIcon(IDR_MAINFRAME);void CMy0952100407Dlg:DoDataExchange(CDataExchange* pDX)CDialog:DoDataExchange(pDX);/AFX_DATA_MAP(CMy0952100407Dlg)DDX_Text(pDX, IDC_EDIT1, m_EDIT);/AFX_DATA_MAPBEGIN_MESSAGE_MAP(CMy0952100407Dlg, CDialog)/AFX_MSG_MAP(CMy0952100407Dlg)ON_WM_SYSCOMMAND()ON_WM_PAINT()ON_WM_QUERYDRAGICON()ON_EN_CHANGE(IDC_EDIT1, OnChangeEdit1)ON_BN_CLICKED(IDC_BUTTON2, OnButton2)ON_BN_CLICKED(IDC_BUTTON3, OnButton3)ON_BN_CLICKED(IDC_BUTTON4, OnButton4)ON_BN_CLICKED(IDC_BUTTON5, OnButton5)ON_BN_CLICKED(IDC_BUTTON6, OnButton6)ON_BN_CLICKED(IDC_BUTTON7, OnButton7)ON_BN_CLICKED(IDC_BUTTON8, OnButton8)ON_BN_CLICKED(IDC_BUTTON9, OnButton9)ON_BN_CLICKED(IDC_BUTTON10, OnButton10)ON_BN_CLICKED(IDC_BUTTON11, OnButton11)ON_BN_CLICKED(IDC_BUTTON12, OnButton12)ON_BN_CLICKED(IDC_BUTTON13, OnButton13)ON_BN_CLICKED(IDC_BUTTON14, OnButton14)ON_BN_CLICKED(IDC_BUTTON15, OnButton15)ON_BN_CLICKED(IDC_BUTTON16, OnButton16)ON_BN_CLICKED(IDC_BUTTON17, OnButton17)ON_BN_CLICKED(IDC_BUTTON18, OnButton18)ON_BN_CLICKED(IDC_BUTTON19, OnButton19)ON_BN_CLICKED(IDC_BUTTON20, OnButton20)ON_BN_CLICKED(IDC_BUTTON21, OnButton21)ON_BN_CLICKED(IDC_BUTTON22, OnButton22)ON_BN_CLICKED(IDC_BUTTON23, OnButton23)ON_BN_CLICKED(IDC_BUTTON24, OnButton24)ON_BN_CLICKED(IDC_BUTTON25, OnButton25)ON_BN_CLICKED(IDC_BUTTON30, OnButton30)ON_BN_CLICKED(IDC_BUTTON35, OnButton35)ON_BN_CLICKED(IDC_BUTTON36, OnButton36)ON_BN_CLICKED(IDC_BUTTON26, OnButton26)ON_BN_CLICKED(IDC_BUTTON27, OnButton27)ON_BN_CLICKED(IDC_BUTTON28, OnButton28)ON_BN_CLICKED(IDC_BUTTON31, OnButton31)ON_BN_CLICKED(IDC_BUTTON32, OnButton32)ON_BN_CLICKED(IDC_BUTTON33, OnButton33)ON_BN_CLICKED(IDC_RADIO1, OnRadio1)ON_BN_CLICKED(IDC_RADIO3, OnRadio3)ON_BN_CLICKED(IDC_RADIO2, OnRadio2)ON_BN_CLICKED(IDC_RADIO4, OnRadio4)/AFX_MSG_MAPEND_MESSAGE_MAP()/ CMy0952100407Dlg message handlersBOOL CMy0952100407Dlg:OnInitDialog()CDialog:OnInitDialog();/ Add About. menu item to system menu./ IDM_ABOUTBOX must be in the system command range.ASSERT(IDM_ABOUTBOX & 0xFFF0) = IDM_ABOUTBOX);ASSERT(IDM_ABOUTBOX AppendMenu(MF_SEPARATOR);pSysMenu-AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);/ Set the icon for this dialog.
