I wrote a AHK script wich can scroll like firefox.

U can press the middle mousekey ( MButton Down) and move the mouse up or down....then u scroll up or down.

I don't scroll per pixel but per lines.
but i want to scroll per pixel:

this is what i have until now:
Code:

#Persistent
SetTimer, WatchScrollBar, 100
return

WatchScrollBar:
  ActiveWindow := WinExist("A")
  if not ActiveWindow  ; No active window.
      return
  ControlGetFocus, FocusedControl, ahk_id %ActiveWindow%
  if not FocusedControl  ; No focused control.
      return
  else
  {
    ControlGet, ChildHWND, Hwnd,, %FocusedControl%, ahk_id %ActiveWindow%
    DllCall("ScrollWindowEx" , UInt, ChildHWND, Int, 0, Int, -1, Int, NULL, Int, NULL)
  }
return

if u execute this coce the active window will move up but in a crappy way...and it don't scrolls not in a usual way.

Please help me with this problem.
the best script u could give to me is a code with a function like that i think:

scrollPerPixel(hwnd, speed, horizontalORvertical)

that i can use it like: scrollPerPixel(hwnd, 3, 0) ; 3 stands for the pixel( up or down per minus oder plus)| and 0 stands for horizintal or vertical


THAAAANX
if there' any questions becouse i wrote: Question Question please ask or contact me

details to the actual FRAn-FireScroll:
the programm is updateable and..
it distinguishes between a hight distance ( == hightspeed scroll) and lowspeed.

but there's a compromis. I use the standardscroll-line:
start > system configuration > mouse > wheel > "lines per scroll" = 1

and then if someone Scroll's down....i simulate more scrolls (i made new options for this)

there's a table where u can add programs in wich u don't want to scroll like in firefox

any way...

i swear that there is no kiddy-virus or somesing like that inside.
but i can undestand if u are sceptic

Scroll notepad:
Hotkeys: 0-9 for speed, up & down for direction, ESC to exit.
Just run it (language independent)!
Code:
SplitPath A_AhkPath, , AhkDir
Run Notepad.exe %AhkDir%\license.txt, , , pID
WinWait ahk_pid %pID%
ControlMove Edit1, , , , 10000
d = -1 ; direction
step = 1
delay = 5

Loop
{
   start := A_TickCount
   ControlGetPos, , y, , , Edit1
   y := y + d * step
   ControlMove Edit1, , y
   Sleep % delay
   ToolTip % "Speed " step * (Abs(d) * 1000 / (A_TickCount - start)) " pixels / s"
}

Up:: d = 1
Down:: d = -1
0:: step = 0
1:: delay := 50, step := 1
2:: delay := 33, step := 1
3:: delay := 17, step := 1
4:: delay := 0, step := 1
5:: delay := 0, step := 2
6:: delay := 0, step := 4
7:: delay := 0, step := 6
8:: delay := 0, step := 8
9:: delay := 0, step := 10
Esc::
WinClose ahk_pid %pID%
ExitApp
