Delphi/C#: WebBrowser socks5 proxy (with username/password auth)

Question

How to use SOCKS 5 proxy with login/password in WebBrowser (IE 8/9)?

In Delphi I tried something like this:

var
  PIInfo: PInternetProxyInfo;
begin
  New(PIInfo);
  PIInfo^.dwAccessType := INTERNET_OPEN_TYPE_PROXY;
  PIInfo^.lpszProxy := PChar('socks=127.0.0.1:1080');
  PIInfo^.lpszProxyBypass := PChar('');
  UrlMkSetSessionOption(INTERNET_OPTION_PROXY, piinfo, SizeOf(Internet_Proxy_Info), 0);
  Dispose(PIInfo);
  WebBrowser1.Navigate('http://www.google.com');
end;

but looks like it works only if proxy doesn't require login/password authentication.

As well as Delphi. Maybe someone who use C# know solution for this problem. For me both languages are suitable. — Alex P., Jun 03 '12 at 09:05

Bsalsa's embedded webbrowser allows you to specify proxy username/password.

As I know it supports only HTTP proxy, not SOCKS 5. – Alex P. Jun 03 '12 at 11:58
I am not certain if IE8/9 supports socks5: http://stackoverflow.com/a/8324536/800214 ?? http://superuser.com/a/383612 – whosrdaddy Jun 03 '12 at 15:17
I would say: try it with TEmbeddedWb (use socks5:// prefix for your proxyserver) – whosrdaddy Jun 03 '12 at 16:43
