VC实现对话框窗口任意分割

    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;
}
