auto Complete Website Username and Password Popup

[Webstyles]

Hi i have a few buttons on a form that link to website url's that i would like to login to automatically, But they have a pop-up login that is displayed.
I have a text file where i store the user names and passwords and then read them as variables. How can i get them to be entered automatically when i click on the link buttons in my form?

Thank you in advance

You have different ways to do this. First of all get the pop-up url in place of the url where the pop-up shows up.
I don't know if you are familiar with doing posts on the internet? Throw a look at httpwebrequest/response or sockets. With these classes you can create objects to retreive or post data on the iNet.
