Checking for newer versions

How do I setup a method of accessing the internet to check for newer versions of an application and then notifying the user if they need to download or not?

One simple way could be having a plain text file with the last version number in server and check with inet control.
In example:
Sub CheckVer()
Dim sver As String, i As Integer
Dim sVerMajMin() As String
' contents of myprogver.txt: 2.1
sver = Inet1.OpenURL("http://mydomain.com/updates/myprogver.txt", icString)
sVerMajMin = Split(sver, ".", , vbTextCompare)
For i = UBound(smajminver) - 1 To 0 Step -1
    If smajminver(i) > App.Minor Then
        MsgBox "You need to update your app"
        Exit For
    End If
    If smajminver(i) > App.Major Then
        MsgBox "You need to update your app"
        Exit For
    End If
   
Next i
End Sub

One approach would be to use the XMLHTTP object from MSXML2 to POST a request with the current version to an ASP page.  THe ASP on the server would check version and notify in a response whether a new version is required.
