在CMainFrame中定义变量：

CSplitterWnd m_wndSplitter;

BOOL CMainFrame::ReplaceView(int row, int col, CRuntimeClass *pViewClass, SIZE
    size)
{
    CCreateContext context;
    BOOL bSetActive;

    if ((this->m_wndSplitter.GetPane(row, col)->IsKindOf(pViewClass)) == TRUE)
        return FALSE;

    //获取文档对象的指针，以便在创建新视图的过程中能够使用它
    CDocument *pDoc = ((CView*)m_wndSplitter.GetPane(row, col))->GetDocument();

    CView *pActiveView = this->GetActiveView();
    if (pActiveView == NULL || pActiveView == m_wndSplitter.GetPane(row, col))
        bSetActive = TRUE;
    else
        bSetActive = FALSE;

    pDoc->m_bAutoDelete = FALSE; //设置标志，这样当视图销毁时不会删除文档
    ((CView*)m_wndSplitter.GetPane(row, col))->DestroyWindow(); //删除存在的视图
    pDoc->m_bAutoDelete = TRUE; //设回默认的标志


    //创建新视图
    context.m_pNewViewClass = pViewClass;
    context.m_pCurrentDoc = pDoc;
    context.m_pNewDocTemplate = NULL;
    context.m_pLastView = NULL;
    context.m_pCurrentFrame = NULL;
    m_wndSplitter.CreateView(row, col, pViewClass, size, &context);


    CView *pNewView = (CView*)m_wndSplitter.GetPane(row, col);

    if (bSetActive == TRUE)
        this->SetActiveView(pNewView);

    m_wndSplitter.RecalcLayout(); //重新计算位置
    // m_wndSplitter.GetPane(row,col)->SendMessage(WM_PAINT);

    return TRUE;
}

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext *pContext)
{
    if (!m_wndSplitter.CreateStatic(this, 1, 2))
        return FALSE;

    if (!m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CTView), CSize(200, 100),
        pContext))
        return FALSE;

    if (!m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CFView), CSize(100, 100),

        return FALSE;

    m_bFormView = true;
    return TRUE;
}

    m_bFormView = true;
}

void CMainFrame::OnListView()
{
    ReplaceView(0, 1, RUNTIME_CLASS(CVVView), CSize(100, 100));
    m_bFormView = false;

}

void CMainFrame::OnUpdateFormView(CCmdUI *pCmdUI)
{
    pCmdUI->SetCheck(m_bFormView);
}

void CMainFrame::OnUpdateListView(CCmdUI *pCmdUI)
{
    pCmdUI->SetCheck(!m_bFormView);
}
