我用CSplitterWnd分割完窗口为什么显示不出来,,,请高手指教

可以运行,但显示的是原来的那个视图,
BOOL   CMainFrame::OnCreateClient(LPCREATESTRUCT   lpcs,   CCreateContext*   pContext)  
{
//   TODO:   Add   your   specialized   code   here   and/or   call   the   base   class
m_split.CreateStatic(this,1,2,WS_CHILD|WS_VISIBLE,AFX_IDW_PANE_FIRST);
m_split.CreateView(0,0,RUNTIME_CLASS(CView1),CSize(100,100),pContext);
m_split.CreateView(0,1,RUNTIME_CLASS(CView2),CSize(100,100),pContext);
SetActiveView((CView*)m_split.GetPane(0,0));  
return   CFrameWnd::OnCreateClient(lpcs,   pContext);
}
m_split是MainFrame的一个变量..

return   TRUE;

CreateView时设定一个视图的宽度，另一个设为0自适应
