C / C++ / MFC

Hi,

SplitterWnd problem (Size of views !!!)

SplitterWnd-Problem in MFC-SDI-App in VC++.

What I want :
+-------------+------------+
|             |            |
| CTReeView   ^ CFormView  |
|             |            |
+----<---[Splitter]-->-----+
|                          |
|        CLIstView         |
|                          |
+--------------------------+
What I get :
The two upper views get very small. All splitters
are there, I just have to pull the middle splitter
downwards to get the View I want.
+-------------+------------+
+----<---[Splitter]-->-----+
|                          |
|        CLIstView         |
|                          |
+--------------------------+

This is the code I use. I have changed the size-parameter of CreateView serveral times but it did not help.
I even tried to change the size after the create. Nothing seemed to work.
Whats going wrong ?

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT /*lpcs*/, CCreateContext* pContext) 
{
    // create splitter windows

    CRect rect;
    GetClientRect(rect);
    //Get size for views
    CSize sizeListView(rect.right,rect.bottom/2);
    CSize sizeTreeView(rect.right/2,rect.bottom/2);
    CSize sizeFormView(rect.right/2,rect.bottom/2);

    //Create splitter top - bottom
    if (!m_wndSplitterTopBottom.CreateStatic(this, 2, 1))
        return FALSE;

    //Connect bottom view
    if (m_wndSplitterTopBottom.CreateView(  1,
                  0,
                  RUNTIME_CLASS(CListView1), 
                  sizeListView, 
                  pContext)) {

        //Create splitter for upper views
        if (m_wndSplitterLeftRight.CreateStatic(
                  &m_wndSplitterTopBottom, 
                  1, 
                  2,
                  WS_CHILD | WS_VISIBLE,
                  m_wndSplitterTopBottom.
                        IdFromRowCol(0, 0)))
        {
            //Connect left upper view
            if (m_wndSplitterLeftRight.CreateView(
                  0,
                  0,
                  RUNTIME_CLASS(CMyTreeView), 
                  sizeTreeView, 
                  pContext) 
                &&
                //Connect right upper view
                m_wndSplitterLeftRight.CreateView(
                  0, 
                  1,
                  RUNTIME_CLASS(CMyFormView), 
                  sizeFormView,
                  pContext) 
                ) 
            {

            
            }
            else {
                m_wndSplitterLeftRight.DestroyWindow();
                return FALSE;
            }
        }
        else {

            return FALSE;
        }
    }
    else {
        m_wndSplitterTopBottom.DestroyWindow();
        return FALSE;
    }

    return TRUE;
}

Thanks
