vb.net - 如何使用 VB 和 Web 浏览器元素通过按钮登录

Question

我在表单中添加了一个 Web 浏览器元素，并且能够在框中输入信息。输入网页尝试下载的正确信息时，如何阻止这种情况发生？

Public Class Form1
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

    Dim usernameTextBox As HtmlElement = Me.WebBrowser1.Document.All.Item("Email")
    usernameTextBox.InnerText = "******"

    Dim passwordTextBox As HtmlElement = Me.WebBrowser1.Document.All.Item("Password")
    passwordTextBox.InnerText = "******"
End Sub

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    WebBrowser1.Navigate(New Uri("https://squareup.com/terminal/"))
End Sub
End Class
