EMail Extracting, Email Parsing, Email Harvesting

Could anyone tell me how some of the email harvesters out there are able to parse multiple web pages a one time and extract thousands of emails within a matter of a few mins.

Are they using web browser control or is there another method cause I have tried extracting links and text in Visual Basic 2008 using the webbrowser control with only my program freezing up on me.

There must be a better way then using the web browser control or maybe a better method of using the web browser control more effectively.

Anyone have any input or experience on this?

Please pm me if you have any help to offer.

Thanks! :tee:

U need to use HttpWebRequest and HttpWebResponse with multi-threading to scrape things.. Learn how to use them, and u can write a bot.. Faster than u expect. .. Hope that helps...
