CDC* pControlDC=pWnd->GetDC;
pWnd->Invalidate();
pWnd->UpdateWindow();
pControlDC->SelectStockObject(NULL);
pControlDC->SelectObject(&BLACK);
pControlDC->Polygon(mypolygon->m_points.GetData(), mypolygon->m_points.GetSize());
pWnd->ReleaseDC(pControlDC);
结果编译时报错：error C2440: 'initializing' : cannot convert from 'class CDC *(__thiscall CWnd::*)(void)' to 'class CDC *'
There is no context in which this conversion is possible

pWnd->Invalidate();

pControlDC->SelectStockObject(NULL);
pControlDC->SelectObject(&BLACK);
pControlDC->Polygon(mypolygon->m_points.GetData(), mypolygon->m_points.GetSize());
