Restricting the size of a splitter pane

I find the solution about restrict the size of the pane.
    First derive class XSplitterWnd from CSplitterWnd,
    Then handle the WM_ONSIZE,call the SetColInfo() and SetRowInfo() in OnSize function.
    And handle the WM_MOUSEMOVE and WM_SETCURSOR to prevent user from changing size.

void XSplitterWnd::OnSize(UINT nType, int cx, int cy) 
{
 RECT        rect;
 int         Height;
 GetClientRect( &rect );
        
 Height = rect.bottom - rect.top - 36;
        
 if ( m_pRowInfo != NULL )
  if ( Height < 0 )
   SetRowInfo( 0, 1, 1);
  else
   SetRowInfo( 0, Height, Height );

 CSplitterWnd::OnSize(nType, cx, cy);

 // TODO: Add your message handler code here
}

void XSplitterWnd::OnMouseMove(UINT nFlags, CPoint point) 
{
 // TODO: Add your message handler code here and/or call default
       
 //CSplitterWnd::OnMouseMove(nFlags, point);
}

void XSplitterWnd::OnLButtonDown(UINT nFlags, CPoint point) 
{
 // TODO: Add your message handler code here and/or call default
        
 //CSplitterWnd::OnLButtonDown(nFlags, point);
}

BOOL XSplitterWnd::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message) 
{
 // TODO: Add your message handler code here and/or call default
        
 //return CSplitterWnd::OnSetCursor(pWnd, nHitTest, message);
 return FALSE;
}
Any comments and suggests, please let me know.
