双击即可自动创建一个点击事件处理函数。

BEGIN_MESSAGE_MAP(CMFCApplication2Dlg, CDialogEx)
    
    	ON_BN_CLICKED(IDC_BUTTON1, &CMFCApplication2Dlg::OnBnClickedButton1)
    END_MESSAGE_MAP()
    
    
    
    void CMFCApplication2Dlg::OnBnClickedButton1()
    {
        
    	
    }

## Radio ##

void CMFCApplication2Dlg::DoDataExchange(CDataExchange* pDX)
    {
        
    	CDialogEx::DoDataExchange(pDX);
    	//关联变量和单选框
    	DDX_Radio(pDX, IDC_RADIO1, m_gender);
    }
    
    BEGIN_MESSAGE_MAP(CMFCApplication2Dlg, CDialogEx)
    	//关联按钮点击
    	ON_BN_CLICKED(IDC_BUTTON1, &CMFCApplication2Dlg::OnBnClickedButton1)
    END_MESSAGE_MAP()
    
    
    //点击按钮弹出选中信息
    void CMFCApplication2Dlg::OnBnClickedButton1()
    {
        
    	//将选中的信息更新到变量m_gender
    	UpdateData(TRUE);
    
    	switch (m_gender)
    	{
        
    	case 0:
    		//mfc 默认第一个单选按钮是0
    		AfxMessageBox("选中0");
    		break;
    	case 1:
    		//mfc 默认第二个单选按钮是1
    		AfxMessageBox("选中1");
    		break;
    	default:
    		AfxMessageBox("选中default");
    		break;
    	}
    	
    }

## CheckBox ##

`MFC`允许每个复选框关联一个`BOOL`类型的变量。

void CMFCApplication2Dlg::DoDataExchange(CDataExchange* pDX)
    {
        
    	CDialogEx::DoDataExchange(pDX);
    	
    	DDX_Check(pDX, IDC_CHECK1, m_swing);
    	DDX_Check(pDX, IDC_CHECK2, m_running);
    	DDX_Check(pDX, IDC_CHECK3, m_basketball);
    }
    
    BEGIN_MESSAGE_MAP(CMFCApplication2Dlg, CDialogEx)
    	//关联按钮点击事件
    	ON_BN_CLICKED(IDC_BUTTON1, &CMFCApplication2Dlg::OnBnClickedButton1)
    END_MESSAGE_MAP()
    
    
    //点击按钮弹出选中信息
    void CMFCApplication2Dlg::OnBnClickedButton1()
    {
         
    	//将选中的信息更新到变量m_swing  m_running m_running
    	UpdateData(TRUE);
    
    	char out[99];
    	wsprintf(out,"选中游泳 %s  选中跑步 %s  选中篮球 %s", m_swing?"是":"否", m_running ? "是" : "否", m_basketball ? "是" : "否");
    	AfxMessageBox(out);
    	
    }

我们看下如何添加选项

//点击按钮弹出选中信息
    void CMFCApplication2Dlg::OnBnClickedButton1()
    {
         
    	//给下拉框添加选项
    	combo.AddString("君岛安娜");
    	combo.AddString("泷泽萝拉");
    	combo.AddString("小泽玛丽");
    	combo.AddString("波多野结衣");
    
    }

void CMFCApplication2Dlg::OnBnClickedButton2()
    {
        
    	//获取当前选中的下标indics
    	int currentIndex = combo.GetCurSel();
    	char name[99];
    	CString ms;
    	//选中的下标的文本
    	combo.GetLBText(currentIndex, ms);
    	wsprintf(name, "选中的下标%d %s ", currentIndex, ms);
    
    	AfxMessageBox(name);
    
    }

## ListControl ##

//添加选项
    void CMyMFCSubProcedureDlg::OnBnClickedButton1()
    {
        
    	//添加表头
    	list_ctl.InsertColumn(0, "ID");
    	list_ctl.InsertColumn(1, "姓名");
    	list_ctl.InsertColumn(2,"性别");
    
    	//设置列宽度为标题栏内容所占宽度
    	list_ctl.SetColumnWidth(0, LVSCW_AUTOSIZE_USEHEADER);
    	list_ctl.SetColumnWidth(1, LVSCW_AUTOSIZE_USEHEADER);
    	list_ctl.SetColumnWidth(2, LVSCW_AUTOSIZE_USEHEADER);
    
    	根据表头类获取列数自动调整列宽
    	//CHeaderCtrl* ctl=list_ctl.GetHeaderCtrl();
    	//for (size_t i = 0; i < ctl->GetItemCount(); i++)
    	//{

    	//}
    	//
    
    	//固定给某行的第一列插入数据,当然可以用SetItemText
    	list_ctl.InsertItem(0, "1001");
    	list_ctl.InsertItem(1, "1002");
    	list_ctl.InsertItem(2,"1003");
    	
    	//给第0行插入数据
    	list_ctl.SetItemText(0, 0, "ID哦");
    	list_ctl.SetItemText(0, 1, "蜡笔小新");
    	list_ctl.SetItemText(0,2,"男");
    
    	//给第1行插入数据
    	list_ctl.SetItemText(1, 0, "ID不知道");
    	list_ctl.SetItemText(1, 1, "波多野结衣");
    	list_ctl.SetItemText(1, 2, "男");
    
    	//修改风格
    	list_ctl.SetExtendedStyle(list_ctl.GetExtendedStyle() | LVS_EX_FULLROWSELECT|LVS_EX_GRIDLINES);
    }

//获取选中
    void CMyMFCSubProcedureDlg::OnBnClickedButton2()
    {
        
    	//选中第几行
    	int index = list_ctl.GetSelectionMark();
    	CString cid = list_ctl.GetItemText(index, 0);
    	CString cName = list_ctl.GetItemText(index, 1);

    	char out[88];
    	wsprintf(out,"cid  %s %s %s 选中第几行 %d", cid , cName,cGender,index);
    	AfxMessageBox(out);
    }

//删除
    void CMyMFCSubProcedureDlg::OnBnClickedButton3()
    {
        
    	//选中第几行
    	int index = list_ctl.GetSelectionMark();
