VC++ 怎么给SDI界面加入像网页上输入邮箱，密码那样的对话框

1.添加登陆对话框资源,在资源中添加两个文本框
2.使用类向导添加对话框类,并添加成员变量
3.在应用程序类的InitInstance()方法添加代码:

CMainFrame* pFrame = new CMainFrame;
m_pMainWnd = pFrame;

// create and load the frame with its resources

pFrame->LoadFrame(IDR_MAINFRAME,
WS_OVERLAPPEDWINDOW | FWS_ADDTOTITLE, NULL,
NULL);

// The one and only window has been initialized, so show and update it.
pFrame->ShowWindow(SW_SHOW);
pFrame->UpdateWindow();
Login dlg ;
dlg.DoModal();
