Copy this html to a notepad, save as .htm (all files) and open it. You will see a captcha image...

Thanks

When the page has finished loading:
Code: Select all
For Each el As HtmlElement In WebBrowser1.Document.All
    If el.GetAttribute("class") = "captcha-img left" Then
        WebBrowser1.Navigate(el.FirstChild.FirstChild.GetAttribute("src"))
        Exit For
    End If
Next

Re: [HOW TO]Webbrowser shows only CAPTCHA

@MrAksel I added that in the DocumentComplete event and it didn't work.

This would be more reliable:
Code: Select all
    Private Sub WebBrowser1_DocumentCompleted(sender As System.Object, e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted

        Dim form As HtmlElement = WebBrowser1.Document.GetElementById("form_confirm")
        If Not form Is Nothing Then

            Dim imgs As HtmlElementCollection = form.GetElementsByTagName("img")
            Dim src As String = imgs(0).GetAttribute("src")
            WebBrowser1.Navigate(src)
        End If


    End Sub

        End If


    End Sub
