The link Post #4 looks quite good, but the limitation on objects on the form might be a problem. Also, that is a designing tool, and i am not sure how well that would translate into code afterwards. I didn't realize post #6 was a different link! Is that the same program? They haven't yet given me a Windows laptop, so i have not been able to check out the code directly.
The rows and seats are not so uniform. The seats are the same size, but where they line up is different, due to polls or whatnot. That is why a map seems so attractive, even though the coordinates would need to be recorded for each seat. As the seats rarely change, however, i am not sure that is much of a problem.
You say subforms are not much more complex. Would i be able to use a few of them seamlessly to give the the impression of it being exactly one map? The subforms have the advantage of not having to worry about size. Also, would i have to code each button separately?
