如何设置MFC静态文本背景为透明色？

增加WM_CTRLCOLOR消息处理函数，并增加如下代码：

 HBRUSH CWebCautionDlg::OnCtlColor(CDC* pDC,CWnd* pWnd,  UINT nCtlColor)
{
 HBRUSH hbr = CDialogEx::OnCtlColor(pDC,pWnd, nCtlColor);

 // TODO:  Change any attributes of the DC here
 //MessageBox(_T("static text"));
 if (pWnd->GetDlgCtrlID() == (IDC_STATIC_COPYRIGHT))
 {
  //MessageBox(_T("static text"));
  pDC->SetBkMode(TRANSPARENT);
  pDC->SetTextColor(RGB(0,225,225));
  return HBRUSH(GetStockObject(HOLLOW_BRUSH));
 }
 // TODO:  Return a different brush if the default is not desired
 return hbr;
}
