C++ Get screen resolution on active monitor

How can I get screen resolution for monitor where my C++ application currently is?

I can get handle to an active monitor:

HMONITOR active_monitor = MonitorFromWindow(GetActiveWindow(), MONITOR_DEFAULTTONEAREST);

But cannot make anything out of this)

I tried this:

HDC hdc = GetDC(GetActiveWindow());
if (hdc)
  {
  const int X = GetDeviceCaps(hdc, HORZRES);
  const int Y = GetDeviceCaps(hdc, VERTRES);
  ReleaseDC(NULL, hdc);
  }

But it did not work.. How is ot possible to get resolution for active monitor?

Thanks, Zhenya

Please try GetMonitorInfo() which gives you a MONITORINFO.
