i just packed few dllcalls and sendmessages for Scrollbars
note that it works on standard scrollbar only. which means not compatible with IE/Firefox

Download SB.ahk to /Lib

Code:
; - Parameters
; hwnd = Unique ID(hwnd) of the control where Scrollbar belongs to, not window
; Which = "V"(vertical) or "H"(horizontal), can be 1(V) or 0(H) too

; - Basic Functions
; SB_GetPos(hwnd, Which="V")
; SB_SetPos(hwnd, Which="V", To="0")    ;it does not scroll the pages actually
; SB_GetRange(hwnd, Which="V")          ;eg) Min,Max
; SB_Show(hwnd, Which="V")              ;Use carefully
; SB_Hide(hwnd, Which="V")              ;Use carefully
;
; - Functions To scroll the page actually
; SB_LineUP(hwnd, Which="V")
; SB_LineDown(hwnd, Which="V")
; SB_PageUp(hwnd, Which="V")
; SB_PageDown(hwnd, Which="V")
; SB_Top(hwnd, Which="V")
; SB_Bottom(hwnd, Which="V")

SendInput, LineEnd

;Get hwnd of control where the scrollbar belongs to
    ControlGet, Notepad, hwnd,, Edit1, ahk_class Notepad

;Start to controlling the scrollbars
MsgBox, % "Range of Vertical scrollbar is (Min,Max) : " SB_GetRange(Notepad)

I was so excited to see your scripts for controlling scroll bars, but when I pasted your sript in an ahk file and ran it, I get "Error: Call to nonexistent function" for all the SB_ functions.
Am I missing something obvious?

put SB.ahk in the AutoHotkey/Lib directory or #include where the file is located.

Code:
; SB_SetPos(hwnd, Which="V", To="0")    ;it does not scroll the pages actually

What can we make to make it also scroll? We need a new function which detects the current location of the scrollbar, left mouse clicks on it and keeps pressing, then SB_SetPos and releasing the left mouse button again. This should or could work? Did anyone try this? Using only DllCalls would be also great.
