Does anyone know how I can autoupdate my application? Kind regards, Ruben Noorderijk

There are tons of ways. Pretty much all of them require a second executable. Here is the source used for updating programs on our Intranet. There is update detection code in each executable. When that executable detects that there are updates available, it notifies the user. When the user says "Update," the program launches the updater and closes. This isn't the cleanest or most secure code, but it works.

Imports System.IO
Imports System.Net

Public Class frmMain
    Inherits System.Windows.Forms.Form

#Region " Windows Form Designer generated code "

    Public Sub New()
        MyBase.New()

        'This call is required by the Windows Form Designer.
        InitializeComponent()

        'Add any initialization after the InitializeComponent() call

    End Sub

    'Form overrides dispose to clean up the component list.
    Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
        If disposing Then
            If Not (components Is Nothing) Then
                components.Dispose()
            End If
        End If
        MyBase.Dispose(disposing)
    End Sub

    'Required by the Windows Form Designer
    Private components As System.ComponentModel.IContainer

    'NOTE: The following procedure is required by the Windows Form Designer
    'It can be modified using the Windows Form Designer.  
    'Do not modify it using the code editor.
    Friend WithEvents Button1 As System.Windows.Forms.Button
    Friend WithEvents RichTextBox1 As System.Windows.Forms.RichTextBox
    Friend WithEvents ProgressBar1 As System.Windows.Forms.ProgressBar
     Private Sub InitializeComponent()
        Dim resources As System.Resources.ResourceManager = New System.Resources.ResourceManager(GetType(frmMain))
        Me.Button1 = New System.Windows.Forms.Button
        Me.RichTextBox1 = New System.Windows.Forms.RichTextBox
        Me.ProgressBar1 = New System.Windows.Forms.ProgressBar
        Me.SuspendLayout()
        '
        'Button1

        Me.Button1.Enabled = False
        Me.Button1.FlatStyle = System.Windows.Forms.FlatStyle.System
        Me.Button1.Location = New System.Drawing.Point(360, 8)
        Me.Button1.Name = "Button1"
        Me.Button1.Size = New System.Drawing.Size(72, 32)
        Me.Button1.TabIndex = 2
