MultiThread form submitter

Hello coders! This project is for a program that will read informations from a mysql database. For each line in the query, the program has to multithread a form post to get some information on the logged area in a site. The site that we need to log on has a rsa encryptation for the password (we must encrypt!) and captcha (just need a textbook to type the captcha). Results need to be written in a mysql database. The program would be much more affective if it could create a new thread for each link, or some other method that allows it to execute every link at the same time instead of waiting for each 1 to finish. The langague needs to be vba .net and we need the code for futures edits. For further information, please bid and get in touch! Thanks, PECCO
