But it's a bit clunky. I was running searches through an embedded webbrowser in a c# application, which is really an embedded internet explorer and was very quickly presented with a captcha. It was a human viewing the results, but a script constructing the query string, but that was enough the be labelled as a crawler.
often all it takes is to be using webbrowser. I would love to use webbrowser for small search utilities because it's so easy to use, but it seems to be a magnet for problems.
