Autonomous/Dashboard and General Programming Questions

[Ganondalf]

Does anybody have a simple, working, autonomous code they could screen cap and post for reference. As for the dashboard, say I wanted to create a light (on the LV dashboard) that turns on every time a limit switch is pressed. How would I go about programming that? I have looked at the 2013 FRC Dashboard guide but I'm still having trouble figuring it out, would anybody be able to walk me through the process. And while I'm asking all of these questions, how do you make your dashboard open simultaneously when you open the driver station, and how would you make a custom message pop up in the user message box upon start up.

Thank you in advance, and thank you to everyone on Chief Delphi that has helped me in the past as well, you have been a huge help!
