找了幾個教程都比較早了

1).插入三個IDD_FORMVIEW

2)新增類：FormView1, FormView2,FormView3 基類：CFormView

3).在Dlg.h中新增

3.1

#include "FormView1"
#include "FormView2"

#include "FormView3”

3.2在Dlg.h中新增

1. public:  
2.     afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);  
3. public:  
4.     CFrameWnd *m_pMyWnd;  
5.     CSplitterWnd m_SplitterWnd;  
6.     CSplitterWnd m_SplitterWnd2;  

3.3在DLg.cpp中定義Oncreate

1. int CSplitDlgDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)  
2. {  
3.     if (CDialog::OnCreate(lpCreateStruct) == -1)  
4.         return -1;  
5.     CString strMyClass = AfxRegisterWndClass(CS_VREDRAW |CS_HREDRAW,  
6.         ::LoadCursor(NULL, IDC_ARROW),  
7.         (HBRUSH
   ) ::GetStockObject(WHITE_BRUSH),  
8.         ::LoadIcon(NULL, IDI_APPLICATION));  
9.     // Create the frame window with "this" as the parent
10.     m_pMyWnd = new CFrameWnd;  
11.     m_pMyWnd->Create(strMyClass,_T(""), WS_CHILD,  
12.         CRect(0,0,200,200), this);  
13.     m_pMyWnd->ShowWindow(SW_SHOW);     
14.     if (m_SplitterWnd.CreateStatic(m_pMyWnd,1, 2) == NULL) 
    //1行2列
15.     {  
16.         return -1;  
17.     }     
18.     if(m_SplitterWnd2.CreateStatic(&m_SplitterWnd,2,1,WS_CHILD|WS_VISIBLE,m_SplitterWnd.IdFromRowCol(0,1)) == NULL)  
19.     {  
20.         return -1;  
21.     }  
22.     m_SplitterWnd.CreateView(0,0, RUNTIME_CLASS(CMyFormViewOne),  
23.         CSize(100,100), NULL);  
24.     m_SplitterWnd2.CreateView(0,0, RUNTIME_CLASS(CMyFormViewTwo),  
25.         CSize(80,80), NULL);  
26.     m_SplitterWnd2.CreateView(1,0, RUNTIME_CLASS(CMyFormViewThree),  
27.         CSize(80,80), NULL);  
28.  return 0;
29. }

3.4在Dlg.cpp中OnInitDialog()新增

1. CRect rect;  
2. GetWindowRect(&rect);  
3. ScreenToClient(&rect);  
4. m_pMyWnd->MoveWindow(&rect);  
5. m_pMyWnd->ShowWindow(SW_SHOW);
