I'm using Visual Studio 2005
When you click on the FTPConnection icon at the bottom there is what i've got set:-
LocalDirectory = 
NullPassword = MyFTPpassword
serveraddress = ftp.hobbit-hosting.com
ServerDirectory = public_html/ftptest
ServerPort = 21
Username = MyFTPusername
Here is the VB Code
Imports System
Imports System.Windows.Forms
Public Class Form1
    Inherits System.Windows.Forms.Form
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Try
            ' Clear the list-box
            FilesListBox.Items.Clear()
            ' Connect, get files and close
            FtpConnection1.Connect()
            FilesListBox.Items.AddRange(FtpConnection1.GetFiles())
            FtpConnection1.Close()
        Catch ex As Exception
            If FtpConnection1.IsConnected Then
                FtpConnection1.Close()
            End If
            MessageBox.Show(Me, ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
        End Try
    End Sub
End Class
