How do I set the GroupBox's Caption color?

Question

I'm handling WM_CTLCOLORSTATIC like this:

case WM_CTLCOLORSTATIC:
{
  HWND fromHwnd = (HWND) lParam;
  if(fromHwnd == hGroupBox)
  {
    HDC hdcStatic = (HDC) wParam;
    SetTextColor(hdcStatic, RGB(255, 255, 0));
    SetBkMode(hdcStatic, TRANSPARENT);
    return (LRESULT) bckBrush;
  }
}
break;

It uses the returned brush as background color but the SetTextColor() has no effect at all. What am I missing?

Here's all my code:

    int width = 500;
    int height = 350;
    int screenWidth = GetSystemMetrics(SM_CXSCREEN);
