关于MFC中用m_WndSplitter.GetPane方法来获到视图指针出错

<P>我的CMainFrame类中OnCreateClient函数如下写的<BR>BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext) <BR>{<BR>    if (!m_wndSplitter.CreateStatic(this, 1, 3,WS_CHILD | WS_VISIBLE))<BR>    {<BR>        TRACE("Failed to CreateStaticSplitter\n");<BR>        return FALSE;<BR>    }</P>
<P>    // First splitter pane<BR>    if (!m_wndSplitter.CreateView(0, 0,<BR>        RUNTIME_CLASS(FormLeft), CSize(110,160), pContext))<BR>    {<BR>        TRACE("Failed to create command view pane\n");<BR>        return FALSE;<BR>    }</P>
<P>    // Second splitter pane<BR>    if (!m_wndSplitter.CreateView(0, 1,<BR>        RUNTIME_CLASS(CsitView), CSize(510,200), pContext))<BR>    {<BR>        TRACE("Failed to create preview pane\n");<BR>        return FALSE;<BR>    }<BR>    if (!m_wndSplitter.CreateView(0, 2,<BR>        RUNTIME_CLASS(FormRight), CSize(150,160), pContext))<BR>    {<BR>        TRACE("Failed to create command view pane\n");<BR>        return FALSE;<BR>    }<BR>    return TRUE;<BR>}<BR>然后在一另一个类中如下来调用视图类指针<BR>CsitView* FormLeft::FormLeft_getview(void)<BR>{<BR>    CMainFrame *pframe=(CMainFrame*)AfxGetApp()-&gt;m_pMainWnd;<BR>    CsitView *pview=(CsitView*)pframe-&gt;m_wndSplitter.GetPane(0,1);<BR>    return pview;<BR>}<BR>CsitView是我的视图类<BR>但运行的结果是，报错信息为：<BR>Debug Assertion Failed!<BR>File:winsplit.cpp<BR>Line:344<BR>For information on how your program can cause an assertion failure,see the VC documentation on asserts</P>
