上面代码,怎样解决窗口不闪动问题?当我运行程序是拖动左边的窗口,会出现闪动现象,我才用了BOOL CVCKBASEDlg/*(CMyDlg)*//*CCoolTabCtrl*/::OnEraseBkgnd(CDC* pDC){
  return TURE;//CDialog::OnEraseBkgnd(pDC);}
但是出现前后两帧窗口叠加的现象.我又采用了下方法,指定区域刷背景
      HWND hWnd=this->m_hWnd;//GetDlgItem(IDC_ALLMAPVIEW)->GetSafeHwnd();
Graphics graphis(hWnd);
SolidBrush brush(GetSysColor(COLOR_3DFACE));
CRect SampleRect;
::GetClientRect(hWnd,&SampleRect);
graphis.FillRectangle(&brush,SampleRect.left,SampleRect.top,SampleRect.Width( ),SampleRect.bottom);
还是没有得到理想的效果.请求高手帮忙,谢谢!

绘制的时候连带着把背景也绘制了，比如FillSolidRect填充一下客户区背景。
