C++ VC实现对话框窗口任意分割

最近写MFC的程序，想在对话框里实现窗口的任意分割。现在网络资料一大抄，找个东西实在麻烦。总算这个很简单，很快就搞定了，写下来做个笔记。
    个人认为简单问题最好就是直接贴源代码，一看就明白，说来说去反而弄不清楚，那我就少废话了，自己看吧，注释很清楚。

先来张图片

1. 新建一个MFC对话框程序MySplitterDlg。 再插入两个Dialog资源 ，这里一定要选择IDD_FORMVIEW类别的对话框，分别新建类CMyFormView0 和CMyFormView1，基类别选CDialog，一定要选择CFormView。

2. CMySplitterDlg中增加WM_CREATE的消息响应，编辑OnCreate()

int CMySplitterDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (CDialog::OnCreate(lpCreateStruct) == -1)
        return -1;
    // Because the CFRameWnd needs a window class, we will create a new one. I just copied the sample from MSDN Help.
    // When using it in your project, you may keep CS_VREDRAW and CS_HREDRAW and then throw the other three parameters.
    //需要注册窗口类
    CString strMyClass = AfxRegisterWndClass(CS_VREDRAW | CS_HREDRAW,
                   ::LoadCursor(NULL, IDC_ARROW),    (HBRUSH) ::GetStockObject(WHITE_BRUSH),
                  ::LoadIcon(NULL, IDI_APPLICATION));
    // Create the frame window with "this" as the parent
    m_pMyFrame = new CFrameWnd;
    m_pMyFrame->Create(strMyClass,"", WS_CHILD,   CRect(0,0,300,300), this);
    m_pMyFrame->ShowWindow(SW_SHOW);
    // and finally, create the splitter with the frame as the parent
    m_cSplitter.CreateStatic(m_pMyFrame,1, 2); //在Frame里切分视图窗口为1×2，就是一行两列
    m_cSplitter.CreateView(0,0, RUNTIME_CLASS(CMyFormView0),   CSize(100,100), NULL);//第一行一列
    m_cSplitter.CreateView(0,1, RUNTIME_CLASS(CMyFormView1), CSize(100,100), NULL);//第一行二列
     return 0;
}

3. 在CMySplitterDlg::OnInitDialog()中显示Frame

int CMySplitterDlg::OnInitDialog()
{
CDialog::OnInitDialog();

GetWindowRect(&cRect);
ScreenToClient(&cRect);
m_pMyFrame->MoveWindow(&cRect);
m_pMyFrame->ShowWindow(SW_SHOW);

return TRUE;
}
