I have a windows forms application. I use the following code to open a dialog where user selects a PDF file.

Dim myFile As New OpenFileDialog()
 myFile.Filter = "Pdf Files (*.pdf)|*.pdf|All Files (*.*)|*.*"
      If myFile.ShowDialog() = _
              DialogResult.OK Then
        If Dir(myFile.FileName) <> "" Then
          MsgBox("File Exists: " & _
                 myFile.FileName, _
                 MsgBoxStyle.Information)
        Else
          MsgBox("File Not Found", _
                 MsgBoxStyle.Critical)
        End If
      End If

Now I want this PDF file to be saved on my server/FTP. How to achieve this?
Please tell me without using any prompts or dialogs that means, I specify the server address/ FTP address in code and it should save in there.
