Yes--don't make assumptions about how the API works. You'll just end up saying something nonsensical, and respondents can't do much more than point that fact out. Also, if you want useful answers to questions, you need to explain specifically what you need to accomplish, and the conditions under which you need to accomplish it. E.g., bindings will usually change an entire scenario. > Since I have 4,000 files to cycle through I want to do this all > programatically.

What, specifically, don't you get? What method calls have you tried?
