n this tutorial, we cover how to log into a website by interacting with HTML elements in a page using the element ID. Don’t worry if you don’t quite understand it yet, there are a few more tutorials that will explain it in more depth. Interacting with HTML elements is a good way to create a bot that will automate web page tasks. Login a page is accessing (remotely accessing webpage or login ny user name and password)
Explain each line by line

Set your attribute like username (user) and password
Click 2nd button to login remotely from your application
Make text box to enter data and labels for good user interface

Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
WebBrowser1.Navigate("http://login.yahoo.com/")
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
WebBrowser1.Document.GetElementById("login").SetAttribute("value", TextBox1.Text)
WebBrowser1.Document.GetElementById("passwd").SetAttribute("value", TextBox2.Text)
WebBrowser1.Document.GetElementById(".save").InvokeMember("click")
