创建多个按钮响应同一个函数
添加
BEGIN_MESSAGE_MAP(CDialogDlg, CDialog)
        //{{AFX_MSG_MAP(CDialogDlg)
        ON_WM_SYSCOMMAND()
        ON_WM_PAINT()
        ON_WM_QUERYDRAGICON()
        ON_WM_CLOSE()
        ON_BN_CLICKED(IDC_BUTTON1, OnButton1)
        { WM_COMMAND, BN_CLICKED, (WORD)100, (WORD)200, AfxSig_vv,(AFX_PMSG)&OnButton2 },
        //}}AFX_MSG_MAP
END_MESSAGE_MAP()
{ WM_COMMAND, BN_CLICKED, (WORD)100, (WORD)200, AfxSig_vv,(AFX_PMSG)&OnButton2 },
WM_COMMAND :表示控件消息
BN_CLICKED: 表示单击消息
first Word：表示起始id
end   word：表示结束id
AFXSIG_VV :V 表示返回值为void ，v表示接收参数为空
最后一个为处理函数

动态添加按钮
void CDialogDlg::OnButton1() 
{
        // TODO: Add your control notification handler code here
        static UINT uID = 100;
        CButton *p = new CButton;
        CRect rect(0,(uID-100)*50+10,100,(uID-100)*50+10  +50);
        p->Create("aaaa",BS_PUSHBUTTON | WS_CHILD | WS_VISIBLE,rect,this,uID++);
        list.AddTail(p);
}
响应函数
void CDialogDlg::OnButton2() 
{
        // TODO: Add your control notification handler code here
        MessageBox("ok2");
}

析构函数，删除资源
 CDialogDlg::~CDialogDlg()
{
        CButton *p = NULL;
        while(!list.IsEmpty())
        {
                p = list.GetTail();
                list.RemoveTail();
                p->DestroyWindow();
                p=NULL;
        }
}
