Well there are a few ways you can do that.

First off, you can use pure winsock, or inet. Personally I use a wrappper that simplify's this whole process, and I can hand that over if you want.

Anyways, basicly you just have to send the right stuff. Generally a login is based on a PHP doc. That document uses variables to determine whether the data entered is valid or not.

These variables can also be set globally via the url. You just need to look at the form information. Example:

We have the site "www.joesite.com". We want to log the user in when they press a button. First thing we need to inspect would be the login form. Here is what we find:

<form action='/login.phtml' method='post'>
<input type='text' name='username'>
<input type='text' name='pass'>
<input type='submit' value='Log In to Joe Site!'>
</form>

First we need the destination, which is "/login.phtml". Now the page we found this on url was "www.joesite.com/login/form". We simply remove the last page and add the new destination so it would look like this, "www.joesite.com/login/login.phtml".

Now we add on the variables, username and pass.

"www.joesite.com/login/login.phtml?user=MyUser&pass=MyPass"

Always add a ? at the end when adding variables, and a "&" when moving to a new one.

Now that's our url that should log us in. Most of the time you can just go:

Inet1.OpenUrl("www.joesite.com/login/login.phtml?user=MyUser&pass=MyPass")

but in this case we had to 'post' so it might not work, that's where pure winsock comes in and you would connect to the site then send the Http Headers for 'post', and you can probably search google for that.

Hope that cleared some things up.
