MFC改变窗口背景颜色

class CMainWindow : public CFrameWnd{}void CMainWindow::OnPaint () {   CPaintDC dc (this);        CRect rect;   GetClientRect (&rect);   dc.FillSolidRect(&rect, RGB(255, 255, 255));   dc.DrawText (_T ("Hello,MFC"), -1, &rect,   DT_SINGLELINE | DT_CENTER | DT_VCENTER); }

 

上面窗口颜色默认是白色。用dc.FillSolidRect 可以改变默认的颜色
