C / C++ / MFC

I create mdi application with splitter in MainFrame with two areas. In first area i suppose to a static control and MDI child windows in second. The CSplitterWnd is created, but i can`t create MDI child window in splitter  panel. I have the following code in OnCreateClient function
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
	if (!m_mainSplitter.CreateStatic(this, 1, 2, WS_VISIBLE | WS_CHILD, AFX_IDW_PANE_FIRST))
	{
		//MessageBox( "Error setting up m_mainSplitter", "ERROR", MB_OK | MB_ICONERROR );
		return FALSE;
	}
	if (!m_mainSplitter.CreateView(0, 0, RUNTIME_CLASS(CMDIAppView),
		CSize(140, cr.Height()), pContext))
	{
		//MessageBox( "Error setting up splitter view", "ERROR", MB_OK | MB_ICONERROR );
		return FALSE;
	}

	if (!m_mainSplitter.CreateView(0, 1, RUNTIME_CLASS(CMDIAppView),
		CSize(cr.Width()-140, cr.Height()), pContext))
	{
		//MessageBox( "Error setting up splitter view", "ERROR", MB_OK | MB_ICONERROR );
		return FALSE;
	}
	m_bInitSplitter = true;

	return CreateClient(lpcs, NULL);
}

I try to change CChildFrame::OnCreate 
with CWnd* pView = GetDlgItem(AFX_IDW_PANE_FIRST);
cs.hwndParent =  pView->m_hWnd;
but i have a error.  I think that CMDIAppView is  corresponded  to CMDiChild view area in MDI application and conflicted with created splitter, i tryed to create splitterview in another class but still unsuccessful.  
I found article "SDI Application with MDI Child Windows in Static Splitter Pane" by John Z. Czopowik in codeguru but can not download source code from there. Please can anyone explane me how to create mdi child windows in splitter panel.
