Alright, i've made a service that is supposed to check to see if a file exists and if it does, make a copy of it in a different directory. Below is the code that I currently have. As you can guess, it doesn't work properly. I used messageboxes to test it out (turned on 'interact with desktop') and it didn't get past the first IO.File.Copy line. It just kept popping up with the messagebox that I had placed above it and never the one below it. Any ideas? Also, this has to be a service because it's going to be used on one of our servers so a user isn't always logged in.
