1.過載這個函式 OnCreateClient（ctrl+w開啟類嚮導，新增CreatClient訊息）
2.CMyView   繼承一個civew類 
 
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
	// TODO: 在此新增專用程式碼和/或呼叫基類
    
	m_splitterWnd.CreateStatic(this,1,3);

	m_splitterWnd.CreateView(0,0,RUNTIME_CLASS(CMyView),CSize(100,100),pContext);
	m_splitterWnd.CreateView
 
(0,2,RUNTIME_CLASS(CMyFormView),CSize(100,100),pContext);

	m_splitterWnd.CreateView(0,1,RUNTIME_CLASS(CMyEditView),CSize(100,100),pContext);
	//m_splitter2.CreateStatic(&m_splitterWnd,0,1,WS_CHILD|WS_VISIBLE,m_splitterWnd.IdFromRowCol(0,1));
	//m_splitter2.CreateView(0,0,RUNTIME_CLASS(CMyEditView),CSize(100,100),pContext);
 


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