mfc计算器:MFC实现简单功能计算器
疯狂代码 http://CrazyCoder.cn/ :http:/CrazyCoder.cn/VC/Article39924.html 第步:利用MFCAppWizard生成个基于对话框(本工程名为Calc)切换到Resource 在Dialog中 IDD_CALC_DIALOG上双击然后添Control控件按钮做好外观布局改好按钮ID和Caption; 第 2步:为Control控件按钮增加相应变量和事件响应; 第 3步:在CCalcDlg类中添加相应变量; 第 4步:对Control控件按钮事件响应做处理;
代码如下:
第部分(利用ClassWizard添加可不必手动修改)在CalcDlg.h中代码修改如下: // CalcDlg.h : 头文件 // #pragma _disibledevent=> // 对话框数据 enum { IDD = IDD_CALC_DIALOG }; protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV 支持
// 实现 protected: HICON m_hIcon; // 生成消息映射
virtual BOOL _disibledevent=> protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV 支持 // 实现 protected: DECLARE_MESSAGE_MAP }; CAboutDlg::CAboutDlg : CDialog(CAboutDlg::IDD) { } void CAboutDlg::DoDataExchange(CDataExchange* pDX) { CDialog::DoDataExchange(pDX); } BEGIN_MESSAGE_MAP(CAboutDlg, CDialog) END_MESSAGE_MAP
// CCalcDlg 对话框

, m_cInNumber(0) { m_hIcon = AfxGetApp->LoadIcon(IDR_MAINFRAME); } void CCalcDlg::DoDataExchange(CDataExchange* pDX) { CDialog::DoDataExchange(pDX); DDX_Text(pDX, IDC_EDIT, m_csEditText); } BEGIN_MESSAGE_MAP(CCalcDlg, CDialog) ON_WM_SYSCOMMAND ON_WM_PAINT ON_WM_QUERYDRAGICON //}}AFX_MSG_MAP ON_BN_CLICKED(IDC_BTNNUM0, &CCalcDlg::OnBnClickedBtnnum0) ON_BN_CLICKED(IDC_BTNNUM1, &CCalcDlg::OnBnClickedBtnnum1) ON_BN_CLICKED(IDC_BTNNUM2, &CCalcDlg::OnBnClickedBtnnum2) ON_BN_CLICKED(IDC_BTNNUM3, &CCalcDlg::OnBnClickedBtnnum3) ON_BN_CLICKED(IDC_BTNNUM4, &CCalcDlg::OnBnClickedBtnnum4) ON_BN_CLICKED(IDC_BTNNUM5, &CCalcDlg::OnBnClickedBtnnum5) ON_BN_CLICKED(IDC_BTNNUM6, &CCalcDlg::OnBnClickedBtnnum6) ON_BN_CLICKED(IDC_BTNNUM7, &CCalcDlg::OnBnClickedBtnnum7) ON_BN_CLICKED(IDC_BTNNUM8, &CCalcDlg::OnBnClickedBtnnum8)
