请教楼上大虾：我的子切分不成功?
CMainFrame::OnCreateClient(...)
{ 
        //预期效果：______________
                    |     |      |
                    |     |______|
                    |     |      | 
                    |     |      | 
                    |_____|______|    
        //主切分：OK
        m_wndSplitter.CreateStatic(this,1,2);   //.......                          //子切分：Failed
        m_wndSplitter_child.CreateStatic(&m_wndSplitter,2,1,WS_CHILD | 
                                   WS_VISIBLE,m_wndSplitter.IdFromRowCol(0,1));
        m_wndSplitter_child.CreateView(0,0,RUNTIME_CLASS(CSdiMvSplitView),
                                   CSize(100,250),pContext);
        m_wndSplitter_child.CreateView(1,0,RUNTIME_CLASS(CSdiMvSplitView),
                                   CSize(100,250),pContext);        //附：我的视CSdiMvSplitView，拆分条定义于CMainFrame中
        //CSplitterWnd m_wndSplitter;
        //CSplitterWnd m_wndSplitter_child;
}

Windows向窗口发送一个WM_ERASEBKGND消息通知该窗口擦除背景，可以使用
ClassWizard重载该消息的缺省处理程序来擦除背景（实际是画），并返回
TRUE以防止Windows擦除窗口。
//Paint area that needs to be erased.
BOOL CSampleView : : OnEraseBkgnd (CDC* pDC)
{
// Create a pruple brush.
CBrush Brush (RGB (128 , 0 , 128) )// Select the brush into the device context .
CBrush* pOldBrush = pDC—>SelcetObject (&brush)// Get the area that needs to be erased .
CRect reClip
pDC—>GetCilpBox (&rcClip)
//Paint the area.
pDC—> PatBlt (rcClip.left , rcClip.top , rcClip.Width ( ) , rcClip.Height( ) , PATCOPY )//Unselect brush out of device context .
pDC—>SelectObject (pOldBrush )// Return nonzero to half fruther processing .
return TRUE
}
