MFC分屏后，想再次调整大小，出现异常，百思不得其解，请教！

第一步框架类中重载OnCreate'Client函数，并加入如下代码：

	ShowWindow(SW_SHOWMAXIMIZED);
	CRect rect;
	int width, height;
	GetClientRect(&rect);
	width = rect.Width() * 4 / 5;
	height = rect.Height();

	//第一次切分
	m_wndSplitter1.CreateStatic(this, 2, 1);
	m_wndSplitter1.CreateView(0, 0, RUNTIME_CLASS(CSUNRView), CSize(width, height*2/3), pContext);
	m_wndSplitter1.SetRowInfo(1, height / 3, 10);

	//第二次切分
	m_wndSplitter2.CreateStatic(&m_wndSplitter1, 1, 2, WS_CHILD | WS_VISIBLE, m_wndSplitter1.IdFromRowCol(1, 0));
	m_wndSplitter2.CreateView(0, 0, RUNTIME_CLASS(CImageShowDlg), CSize(width / 2, 0), pContext);
	m_wndSplitter2.CreateView(0, 1, RUNTIME_CLASS(CReferencePointDlg), CSize(width / 2, 0), pContext);

在View类中重载OnSize函数，并加入如下代码：

	//修改失败
	CRect rect;
	GetClientRect(&rect);
	int width = rect.Width();
	int hight = rect.Height();

	CMainFrame* pMain = (CMainFrame*)AfxGetApp()->m_pMainWnd;
	pMain->m_wndSplitter2.SetColumnInfo(0, width / 2, 100);//此处出现异常
	pMain->m_wndSplitter2.SetColumnInfo(1, width / 2, 100);
	pMain->m_wndSplitter2.RecalcLayout();

请给分析一下问题出现在哪儿？如何解决？谢谢！
