Problem in resizing controls in a Form View -Find the error out

Hi everyone
Can someone look at my code and tell me where I am going wrong
I have 2 controls in a form view
List box,ListCtrl

The problem is

1.The application comes in restored state and When the application is
maximised the controls become much bigger

2.When I try to resize the controls become smaller and thats fine but
when the resizing touches the WindowDC ,all teh controls disappear.

How should I handle the code

Here is the code and tell me where exactly the problem ?I have searched
lot of sites where they give the code but can anybody point the error
out

MyView.h
 CSize m_sizClient;

After the call to

void CMyView :: OnInitialUpdate{

CFormView::OnInitialUpdate();
GetParentFrame()->RecalcLayout();
ResizeParentToFit();

CRect rc;
GetClientRect(rc);
    m_sizClient.cx = rc.Width();
    m_sizClient.cy = rc.Height();

}

void CMyView::OnSize(UINT nType, int cx, int cy)
{
    CFormView::OnSize(nType, cx, cy);

// CButton* button;
    CRect buttonRect;

if (!(m_sizClient.cx && m_sizClient.cy)) return;

    const int dx = cx - m_sizClient.cx;
    const int dy = cy - m_sizClient.cy;

    if (!(dx || dy)) return;

    m_sizClient.cx = cx;
    m_sizClient.cy = cy;

if(m_myListBox.GetSafeHwnd() != NULL)
{

    CRect rc;

    myListBox.GetWindowRect(rc);
    ScreenToClient(rc);
    rc.right += dx; rc.bottom += dy;
    myListBox.MoveWindow(&rc);

}

if(m_myListCtrl.GetSafeHwnd() != NULL)
{

    CRect rc;
    m_myListCtrl.GetWindowRect(rc);
    ScreenToClient(rc);
    rc.right += dx; rc.bottom += dy;
   m_myListCtrl.MoveWindow(&rc);

}
