Like in the title. I have no idea what to start with in order to implement a search engine like the one in Wrzuta.pl to a VB.NET 2008 application. I reckon this must be possible since I have seen an application doing this at http://www.wdownloader.yoyo.pl/download.php?cmd=click&id=1 - and a lot of mashups online, too.
If anyone by any chance has an idea that would be of any help to me, I'm super glad.
