How to automate form filling on internet.

Hi,
I want to develop a program which will do the following activities:-
1. open a website (website name will be a hardcoded or have to pick from the database),
2. Then provides the login id and password to the website,
3. click on particualar link on the menu,
4.fetch the data from a database (access),
5. paste the data and then submit.
6. Repeats the above steps again and again.

To me, your topic and your requirement do not quite match. you just mentioned what you want to do and didn't mention where you are facing difficulties.

To answer your topic try a software called "roboform". I have tried it and it works perfectly fine with firefox and its free.
