VB6 upgrade problem MSHTML COM with VB.NET [resolved]

[blindlizard]

I have this code from VB6 that works fine

Dim objLink As HTMLLinkElement
    Dim objMSHTML As New MSHTML.HTMLDocument
    Dim objDoc As MSHTML.HTMLDocument
    
    Set objDoc = objMSHTML.createDocumentFromUrl("http://www.yahoo.com", vbNullString)
    
    While objDoc.readyState <> "complete"
        DoEvents
    Wend
    'get all Links
    For Each objLink In objDoc.links
        Debug.Print objLink
    Next

I then run it through the VS.Net VB upgrade tool and get this

Dim objLink As mshtml.HTMLLinkElement
        Dim objMSHTML As New mshtml.HTMLDocument
        Dim objDoc As mshtml.HTMLDocument
 
        objDoc = objMSHTML.createDocumentFromUrl("http://www.yahoo.com", vbNullString)
 
        While objDoc.readyState <> "complete"
            System.Windows.Forms.Application.DoEvents()
        End While
        'get all Links
        For Each objLink In objDoc.links
            System.Diagnostics.Debug.WriteLine(objLink)
        Next objLink

I get an error on the line

objDoc = objMSHTML.createDocumentFromUrl("http://www.yahoo.com", vbNullString)

Saying "An unhandled exception of type 'System.NullReferenceException' occured in mscorlib.dll"
"Additional Information: Object reference not set to an instance of an object"
