看来看去都要求RUNTIME_CLASS，我一写就错，正在绝望中……

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
// TODO: Add your specialized code here and/or call the base class

m_wndSplitter1.CreateStatic(this,1,2,WS_CHILD | WS_VISIBLE, AFX_IDW_PANE_FIRST );
m_wndSplitter1.CreateView(0,0,RUNTIME_CLASS(CMyView),CSize(200,10),pContext);

m_wndSplitter2.CreateStatic(&m_wndSplitter1,2,1,WS_CHILD|WS_VISIBLE,
m_wndSplitter1.IdFromRowCol(0,1));
m_wndSplitter2.CreateView(0,0,RUNTIME_CLASS(CMyView2),CSize(0,300),pContext);
m_wndSplitter2.CreateView(1,0,RUNTIME_CLASS(CMyView3),CSize(0,0),pContext);

return TRUE;
// return CFrameWnd::OnCreateClient(lpcs, pContext);
}

加载以上函数,再定义相关变量,视图类就可以了.

这是静态切分.
