[2008] WebBrowser document

Hi! I've teach me some codes like this document code.. If i want anything on internet that going to write in a textbox i write like this

WebBrowser1.Document.All("ID of the textbox here").InnerText = "this text is in the textbox"

Also on button its .invokemember("click") in the end instead of innertext!

But i also wonder how to make if its going to click on a link?
Also, they not have any ID! And is it anyway to make it click on this link? like they click on the buttons
