Here is some code that works and could stand to be cleaned up a little. You will need to change the below to match your system.
CONST DEFAULT_QDS = "http://localhost:4720/qtxs.asmx"
' member of "QlikView Administrators". If null, then the user who invoked
' the script is used for interactions with the QDS.
CONST USERNAME = "qv10\qvpub" ' "domain\user"
CONST PASSWORD = "qvpub" ' "password"
Also, the task name and password is required. If there is not pass work then leave it blank like this.
