如题，谢谢

[解决办法]
void CMFCFormViewView::OnPaint()
{
CPaintDC dc(this); // device context for painting
CDC memDC;
memDC.CreateCompatibleDC(&dc);
CBitmap bmp;
BITMAP bm;
//IDB_BITMAP1为位图资源
bmp.LoadBitmap(IDB_BITMAP1);
bmp.GetBitmap(&bm);
memDC.SelectObject(&bmp);
dc.BitBlt(0,0,bm.bmWidth ,bm.bmHeight,&memDC,0,0,SRCCOPY);
}
