使用浏览器阻止网站 [英] Blocking Websites with Browser

问题描述

我希望在浏览器中阻止网站，该网站将被阻止的网站存储在my.settings.blockedwebs(这是collections.specialized.stringcollection)中.我让用户将被阻止的网站输入到form1的文本框中，然后将网站添加到stringcollection 按钮具有以下代码:

I wish to block websites in a browser, where the blocked websites are stored in my.settings.blockedwebs (which is a collections.specialized.stringcollection). I let the user input the blocked website into a textbox in form1, and the add website to the stringcollection button has the following code:

 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    If My.Settings.BlockedWebs Is Nothing Then
      My.Settings.BlockedWebs = New System.Collections.Specialized.StringCollection
    End If
    My.Settings.BlockedWebs.Add(TextBox1.Text)
    My.Settings.Save()
    TextBox1.Text = ""

然后使用第二个按钮更新列表框(其中包含所有被阻止的网站)

Then a second button is used to update the listbox (which contains all the blocked websites)

  Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
    For Each a As String In My.Settings.BlockedWebs
      ListBox1.Items.Add(a)
    Next
  End Sub

然后我放

Form1.Label1.Text = Browser.Url.ToString

推荐答案

那么，什么不起作用?您是否已浏览并查看发生了什么?变量a等于b吗?文本框中的字符串是什么?

So, what doesn't work? Did you step through and see what is going on? does the variable a equal b? What string is in the text box?
