; AutoIt Version: 3.0
; Language:       English
; Platform:       WinXP/2003/Vista
; Author:         Marcel Jordaan (mjordaan@rldautomation.eu)
;
; Script Function:
;   Starts the FactoryLink webclient using graph.exe, and accepts the the same commandline parameters as graph.exe.
;   This script will start the weblcient and close all popup messageboxes reporting errors, normally weblcient will close
;   after accepting popup messages!
;   Note: the path variable should be set to the bin-directory where webclient is installed

; Usage:
;   Calling this script in cmd or batch file makes it possible to auto-close webclient after an error,
;   and restart the same or an alternative weblcient connection.
