请问在VC中CDC有什么函数可以用来在OnDraw中清屏，即将CView类窗口恢复纯白。

Question

BOOL CMyView::OnEraseBkgnd(CDC* pDC) 
{
    CBrush backBrush(RGB(255, 255, 255));    
    CBrush* pOldBrush = dc.SelectObject(&backBrush); 
    CRect rect; 
    dc.GetClipBox(&rect);    
    dc.PatBlt(rect.left, rect.top, rect.Width(), rect.Height(), PATCOPY); 
    dc.SelectObject(pOldBrush); 
    return TRUE; 
} 

Answer 1

void CMyView::OnEraseBkgnd(CDC* pDC) 
{
   CBrush backBrush(RGB(255,255,255));
   RECT Rect=GetClientRect(&Rect);
   pDC->FillRect(&Rect,&backBrush);
   return;   
}
