In general is there a good website or tutorial about using vba to interact with the internet?

I have a VBA book and looked at a number of them in the bookstore and don't see anything about this. All I can find online is random forum posts and with people's questions and answers. I'm not really sure what I'm doing.

As for a a website, the one I had in mind requires you to have a login, but another one that looks similar is:

Lets say you want to run code that will put in your email and password, and then let you check your private messages. In order to see the login button you have to have your mouse over the login area on the website. How would you do that with VBA?
