title: Clicking a button(with no id) using mshtml in wpf web browser
body: <p>I'm trying to fill a WPF WebBrowser page using mshtml. But, I'm not able to find out the id of the button from the html. How can I find the ID? Or is there is any alternative to submit the form?</p>
  
  <p>Code:</p>
  
  <pre><code>mshtml.HTMLDocument doc = (mshtml.HTMLDocument)browser.Document;
  
  try
  {     
      ((mshtml.HTMLInputElement)doc.all.item("?????")).click();
  }
  </code></pre>
  
  <p>Html page (Continue is the button text):</p>
  
  <pre><code>&lt;li&gt;&lt;a href="/uas/oauth/authenticate?oauth_token=3c708034-081f-4aca-b61c-f6518a1e0f8c&amp;amp;trk=uas-continue" class="btn-primary"&gt;Continue&lt;/a&gt;&lt;/li&gt;
  </code></pre>
