Ciao, sto provando a estrarre il link di download di un servizio gratuito che scarica canzoni da youtube in mp3.
Sito
L'html di esempio è
Codice:

Dunque nell'evento DocumentCompleted del controllo WebBrowser sto provando con :
Codice: 
 Dim HtmlCollec As HtmlElementCollection
         HtmlCollec = WebBrowser1.Document.GetElementsByTagName("button")
         For Each iElement As HtmlElement In HtmlCollec
             If iElement.GetAttribute("id").Equals("myImageId44") Then
                 RichTextBox1.Text = iElement.ToString
                            End If
         Next

ma come output ottengo
System.Windows.Forms.HtmlElement

Sto provando pure con
Codice: 
Dim element = WebBrowser1.Document.GetElementById("myImageId44")
         If element IsNot Nothing AndAlso element.Document.Links.Count > 0 Then
             Dim link = element.Document.Links(0).GetAttribute("href")
         End If

ma ottengo un link differente da quello di cui ho bisogno.
Questa Gif mostra il comportamento del sito. Qualsiasi soluzione è accetta, e se possibile ricavare il link da webclient sarebbe il massimo, se no mi accontento del WebBrowser. Grazie
