响应WM_CTLCOLOR消息，如下所示：

如果需要全部的control都透明：
HBRUSH CYourDialog::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
pDC->SetBkMode(TRANSPARENT);
return (HBRUSH)GetStockObject(NULL_BRUSH);
}


如果需要指定的control透明：
HBRUSH CYourDialog::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
if(pWnd->GetDlgCtrlID() == ID_YOURCTRL) // ID_YOURCTRL是要透明的control的ID
{
pDC->SetBkMode(TRANSPARENT);
return (HBRUSH)GetStockObject(NULL_BRUSH);
}
else
{
return CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
}
}
