CString s1,s2;

2利用ClassWizard为各按钮添加消息映射并默认给出的函数。 （1）代码如下： void CMyDlg::On0() { s2=s2+\ m_xx=m_xx+\ UpdateData(FALSE);

// TODO: Add your control notification handler code here }

void CMyDlg::On1() { s2=s2+\ m_xx=m_xx+\ UpdateData(FALSE);

// TODO: Add your control notification handler code here }

void CMyDlg::On2() {s2=s2+\

m_xx=m_xx+\ UpdateData(FALSE);

// TODO: Add your control notification handler code here }

void CMyDlg::On3() {s2=s2+\

m_xx=m_xx+\ UpdateData(FALSE);

// TODO: Add your control notification handler code here
