CSplitterWnd继承异常

CSplitterWnd继承错误
我首先新建了一个单文档，
然后从CsplitterWnd继承一个子类CMySplitter
-------------------------------------------------
class   CMySplitter   :   public   CSplitterWnd
{
//   Construction
public:
CMySplitter();
        DECLARE_DYNCREATE(CMySplitter)
//   Attributes
public:

//   Operations
public:

//   Overrides
//   ClassWizard   generated   virtual   function   overrides
//{{AFX_VIRTUAL(CMySplitter)
//}}AFX_VIRTUAL

//   Implementation
public:
virtual   ~CMySplitter();

//   Generated   message   map   functions
protected:
//{{AFX_MSG(CMySplitter)
//   NOTE   -   the   ClassWizard   will   add   and   remove   member   functions   here.
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
};
--------------------
然后在CMainFrame类重载OnCreateClient（）
---------------------
BOOL   CMainFrame::OnCreateClient(LPCREATESTRUCT   lpcs,   CCreateContext*   pContext)  
{
//   TODO:   Add   your   specialized   code   here   and/or   call   the   base   class
       
BOOL   bResult=m_wndsplitter.CreateStatic(this,1,2);
ASSERT(bResult);
            m_wndsplitter.CreateView(0,0,RUNTIME_CLASS(CView1),CSize(200,200),pContext);
    m_wndsplitter.CreateView(0,1,RUNTIME_CLASS(CView2),CSize(600,600),pContext);
return   bResult;
}
---------------------------------------
CMainFrame类
protected:     //   control   bar   embedded   members
CStatusBar     m_wndStatusBar;
CToolBar         m_wndToolBar;
        CMySplitter     m_wndsplitter;

编译后错误
