How to find height of title bar?

[qwert]

At runtime, I want to move my GUI window up so the title bar doesn't show. The height of the title bar differs according to the version of Windows being run (i.e., Vista vs XP -- and Classic vs Std). I can determine the OS version and use a corresponding pixel count, but things are thrown off if the user has specified Classic view.

Is there a simple way to find the title bar height?

Thanks for any help.

_WinAPI_GetSystemMetrics($SM_CYCAPTION)

GUICreate("Title",-1,-1,-1,0 - _WinApi_GetSystemMetrics($SM_CYCAPTION) -3) if you want it to start right at the client area. -3 for the border, which isn't included in the size returned by $SM_CYCAPTION.

Thanks very much for the response. Here's the packaged version for anyone that needs it.

#include <WinAPI.au3>
$res = _WinAPI_GetSystemMetrics($SM_CYCAPTION)
MsgBox(32, "Result", "Height = " & $res)

Also, here's a link to the full list of available metrics: link
