The oldest code that I wrote that I suspect is still in use is RoboGen, an editor for robots.txt files, that I wrote in Visual C++ 6 with MFC. I remember working on it while not paying enough attention in my high school physics class. We were allowed to have laptops in class at the time. You can see it at https://rietta.com/robogen/ https://rietta.com/robogen/. The oldest code that I distributed - it was written by a friend of mine - is Whois Web Professional which was a whois client written in VB6. I know it's still in use because I have to maintain the version file on my website and even keep my server running Apache because its update checking was written by a 12 year old in WinSock and doesn't handle the protocol very well. If I change anything, the VB6 program crashes on startup and I get emails about it. You can see it at https://rietta.com/whoisweb/ https://rietta.com/whoisweb/.
