问题 I am reading midi files in as3 (flash cs5) with the help of the helpful library that is called midas ( http://code.google.com/p/midas3/) - the midi-as3 library. I am trying to figure out a simple way to calculate the whole duration of the midi file (for example - total time of 4 minutes or 6 minutes...). I assume I could calculate the last note of each track + check the tempo and figure it out, but I was wondering if: Is the duration of the midi file is written somewhere in the data that I

Thanks EDIT: Sorry, I'm going to try to be more specific: I'm currently designing a prototype using datasnap 2009. So I've got a thin client, a stateless server app and a database server. What I would be able to do is to detect and handle connection loss (internet connectivity) between the client and the server app to handle it appropriately, ie: Display an informative
