Alright. I have my application watching my desktop, pictures, music, and document folders. I have seen examples of ftp similar to this:

VB

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim request As System.Net.FtpWebRequest = DirectCast(System.Net.WebRequest.Create("ftp://ftp.drivehq.com/file.txt"), System.Net.FtpWebRequest)
        request.Credentials = New System.Net.NetworkCredential("user", "password")
        request.Method = System.Net.WebRequestMethods.Ftp.UploadFile

        Dim file() As Byte = System.IO.File.ReadAllBytes("c:\file.txt")

        Dim strz As System.IO.Stream = request.GetRequestStream()
        strz.Write(file, 0, file.Length)
        strz.Close()
        strz.Dispose()
    End Sub

so for instance. this is the handler:

AddHandler watchfolder.Renamed, AddressOf logrename

What would I need to put into the sub logrename() in order for it to automatically upload the renamed file onto my server

Unlike file systems, FTP does not support notifications.

To implement the feature you want on some host running an FTP server, you would need to develop a special notification service. This service should work on the publisher-subscriber model (http://en.wikipedia.org/wiki/Publish-subscribe[^]), accept subscriptions for event notifications by network and provide network notifications if something changes in part of the file system covered by FTP, depending on user authentication.

Please see for the sketch of such architecture in my past answer:
Multple clients from same port Number[^].

Internally, if the service's host runs Windows, you can use the class System.IO.FileSystemWatcher, please see:
http://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher.aspx[^].

For Windows systems, the adequate form of the service is a Windows Service. Please see:
http://en.wikipedia.org/wiki/Windows_service[^],
http://msdn.microsoft.com/en-us/library/d56de412%28v=vs.100%29.aspx[^].

The application is going to be a .net desktop application, that can upload the changed file onto the ftp server. The server runs Linux. It's with dreamhost.com
I was planning on using the system.io.filesystemwatcher, my problem is that I dont know how to change the ftp portion of my code to work with whatever file was changed, renamed or created...
