这是MFC程序，实现口令对话框，找不到什么地方时错的，刚学MFC     望见谅！







//进行口令询问过程
    CPasswordDialog m_Dlg;
    if(m_Dlg.DoModal()==IDOK)
    {
        if(m_Dlg.m_Password!=1925)
        {//如果口令不对，则显示出错信息，然后程序结束
            MessageBox( NULL,"口令错误，确定后将退出程序。","错误",MB_OK IMB_ICONERROR);
            return FALSE;
        }
    }
    else //如果按下取消按钮，程序也结束
        return FALSE;
这是自己加的函数，其他那些是编程软件自动生成的，，谢谢了
