Have you considered to post your question in the Machine Vision board? It's more likely to get an answer there.
And do not reply to the question yourself if you haven't found the answer. Questions which will have no reply for a certain amount of time will be given to NI support staff and maybe someone there can help you. If a question has at least one reply this will be ommitted.
