I'm working on an auto-updating application which we're going to deploy to about 150 remote field laptops. I'm hung up trying to find the best way to track user stats for each laptop after they have updated. So far my app grabs the laptop name, user name and a few other variables from the laptop after updating, but I want to then write this information back to a database or log file on my web server. I'm looking for the simplest way to implement this be it writing to an xml file on my server or even writing to a log file I can parse later. I'll be using ClickOnce for the automatic updates and this code will be triggered by that event. Any ideas or examples of what others have been doing?
