title: how to download xls file from website without file name and extension in URL?
body: <p>I want to download a file from the website:
  <a href="http://www.trademap.org/Country_SelProduct_TS.aspx?nvpm=1|||||TOTAL|||2|1|1|1|2|1|2|1|1" rel="nofollow noreferrer">http://www.trademap.org/Country_SelProduct_TS.aspx?nvpm=1|||||TOTAL|||2|1|1|1|2|1|2|1|1</a>
  no filename and extension in the URL. on webpage, excel icon (up-left) has to be on-clicked and then the browser savedfiledialog opens. how to automate this and save the file in pc without browser, from vb.net?
  can it be done by webclient.downloadfile?
  thanks</p>
