I just wrote and tested the code below. It gets the coordinates of the  
Windows desktop area (screen not including taskbar) via a Windows API  
call.

Jamal

require ‘Win32API’

def get\_desktop\_area()  
function = Win32API.new(‘user32.dll’, ‘SystemParametersInfoA’, [‘L’,  
‘L’, ‘P’], ‘L’)  
spi\_getworkarea = 48  
structure = ’ ’ \* 4  
function.Call(spi\_getworkarea, 0, structure)  
left, top, right, bottom = structure.unpack(‘L4’)  
end

puts get\_desktop\_area
