Get color in an inactive window

[Bounty666 0]

I want help to get the color in an INACTIVE window. This is the code(my first try):

Func AUTOHEAL()
    BlockInput(1);Blocking input
    $HWt=ControlGetHandle("Game","","");get the handle
    $minhpcolor=PixelGetColor($X,$Y,$HWt);Want to get the color
    If $minhpcolor<>$color_hitpoint Then;If the color have been changed...
        If $Checkbox1="Use hotkey" Then
            
        Else
            ControlSend("Game","","",GUICtrlRead($Input1))
        EndIf
    Else
    EndIf
    BlockInput(0); Unblock input
EndFunc

I want the program to check if the Color at a specific coordinate in an Inactive window have changed. If it has.. Then it shall send $Input1 in the same window. I dont know if this is possible but I also want it to do this if the window is minimized.
