MFC删除Button控件具体操作

1. 删除Button按键；
2. 删除xxxDlg.h中消息映射函数定义

class Ctest4Dlg : public CDialogEx
{...
public://afx_msg void OnBnClickedButton1();...
}

3. 删除xxxDlg.cpp中“DoDataExchange”和“BEGIN_MESSAGE_MAP”中的相关代码

void CtestDlg::DoDataExchange(CDataExchange* pDX)
{CDialogEx::DoDataExchange(pDX);DDX_Control(pDX, IDC_COMBO1, m_combox1);DDX_Text(pDX, IDC_EDIT2, m_Edit2);//DDX_Control(pDX, IDC_BUTTON1, m_Button1);...
}

BEGIN_MESSAGE_MAP(Ctest4Dlg, CDialogEx)ON_WM_SYSCOMMAND()ON_WM_PAINT()ON_WM_QUERYDRAGICON()//ON_BN_CLICKED(IDC_BUTTON1, &Ctest4Dlg::OnBnClickedButton1)...
END_MESSAGE_MAP()

4. 删除xxxDlg.cpp中按键响应函数

//void CtestDlg::OnBnClickedButton1()
//{
//    //TODO: 在此添加控件通知处理程序代码
//    ...
//}
