    You need a server, or some place to host direct links to files.

    Upload on your server a text file and put the name of the current version in it. When you build your project, use like My.Settings.Version and set it as 1.0.0.0, and upgrade it as 1.0.0.1 etc.

    So then
     if (My.Settings.Version == web.DownloadString(url to txt file)
       open up a connection and download the file, then do
      like a new process, and set it to that downloaded file and run it
    

    I assume you just needed the "spring board" for the idea. I was the same way, till someone told me that. Its quite easy to code, once you get better you can include an XML file and use the XML class to read specific stuff from your xml file.
