Hello,

This is not the best auto updater but it gets the job done

Step 1:
Just Add A Text Box Anywhere

Step 2:
Double Click the Form and add this code about Public Class (name of form)
Imports System.IO
Imports System.Xml
Imports System.Net


Step 3:
Add This Code under form load

        If getXMLValue(TextBox1.Text, "latestVersion") = "2.7.0.0" Then 'Change 2.7.0.0 to the assembly version of your app'
            MsgBox("No Update Found", MsgBoxStyle.Information, "No Update")
            Return
        Else
            If MessageBox.Show("Update found! Would you like to download?", "Update Found", MessageBoxButtons.YesNo) = DialogResult.Yes Then
                Dim wc As New WebClient()
                wc.DownloadFile("http://yoursitehere.com/nameofapp.exe", "Name of App" )
            End If
        End If
        Return
    End Sub
    Private Function getXMLValue(ByVal update As String, ByVal setting As String) As String
        Dim xmlr As XmlReader = XmlReader.Create("http://www.yoursitehere.com/version.xml")
        xmlr.Read()
        xmlr.ReadToFollowing(setting)
 
        Dim value As String = xmlr.ReadString()
        xmlr.Close()
 
        Return value
    End Function
Delete the extra End Sub if you get an error
Step 4:
Go to x10hosting.com and sign up for a hosting account.
Then, login into cPanel and go to File Manager.
Then, click upload and upload the NEWEST .exe of your app.

Step 5 (Making the XML File):
Open a new notepad file and add this code to it:
  <?xml version="1.0" encoding="UTF-8"?>
<checkForUpdate>
<latestVersion>1.0.0.0</latestVersion>
</checkForUpdate>


The version number doesn't matter. Now go to file>>>>save as... and make sure you have all files selected and name it version.xml

Step 5:
Upload the version.xml file to x10hosting

Your DONE!

MUST READ!
Now in visual basics go to your apps properties>>>Assembly Information>> and change Assembly Version and File Version to a NEW version. So if your old one was version 2.6.0.0 you MUST CHANGE THIS TO 2.7.0.0 and so on FOR THE AUTO UPDATER TO WORK!

Now each time you want to update your app you MUST change the assembly information to the LATEST version. For example the assembly I used the version number was 2.7.0.0 so that was the latest version. EVERYTIME you want to release a new version you MUST change the version number.

Now when you want to make an update you have to change the .xml file to the NEWEST version number. Do this by going into cPanel>>>File Manager>>right click version.xml>>>code edit>>> then just change the to the NEWEST version of your app!
Also, you must also upload the NEWEST version of your app.exe
