Change the 'Extend my windows desktop...' property

[Jason]

I am trying to figure out how to programatically change the value of
the 'Extend my windows desktop onto this monitor' property under the
Settings tab of the display properties. I figured there would be a WMI
class that could do this, but I can't seem to find this property in a
WMI class. I also figured there may be an API to handle it, but can't
seem to find that info either. I know it changes a registry value, but
I'm trying to avoid going this route.

If you don't get an answer here, give the Win32 groups a try.
