I finally found a way in KiX to be able to enable and disable the QuickLaunch bar. However it doesn't return the state, I spend hours figuring this out and finally had to resort to an external DLL that let's you make DLL Calls, I hope Ruud will incorporate this into KiX.

Anyway here's what you need: DynaWrapper

And here the code, after hours of sorting it out:
 Code:
Function ToggleQL($switch)
  Dim $WM_USER, $WMTRAY_TOGGLEQL, $objItem, $lhWnd
  $WM_USER = &400
  $WMTRAY_TOGGLEQL = ($WM_USER + 237)
  $objItem = CreateObject("DynamicWrapper")
  $=$objItem.Register("USER32.DLL", "FindWindowA", "i=ss", "f=s", "r=l")
  $=$objItem.Register("USER32.DLL", "SendMessage", "I=hlll", "f=s", "R=l")
  $lhWnd = $objItem.FindWindowA("Shell_TrayWnd", "")
  $=$objItem.SendMessage($lhWnd, $WMTRAY_TOGGLEQL, -1, $switch)
EndFunction

The switch = 0 for off and 1 for on.
