WebBrowser using alternating proxies

[simpleonline1234]

My application uses the webbrowser component and currently is setup to handle proxies. I can't seem to figure out how to alternate my proxies in my webbrowser.

For instance I have a list of about 100 proxy by IP:PORT and I can enter each one at a time but not to sure on how to alternate them. I was thinking to setup a counter on my webBrowser completed in my for each statement that I use to grab an html element.

This part I can do but how can I set my code to grab the next proxy after say 20 passes?

Thanks

    For Each element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("a")
            RichTextBox1.Text = RichTextBox1.Text & element.GetAttribute("href") & vbNewLine
        Next

Thinking maybe use a counter?

Public Class tester
Dim counter as integer = 0
_________________________________________________________

  Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        WebBrowser1.Navigate("http://www.mytestsite.com")
         counter = 1
   
    End Sub

If counter = 20 then proxytext.text = ???
For Each element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("a")
RichTextBox1.Text = RichTextBox1.Text & element.GetAttribute("href") & vbNewLine
counter = counter + 1
Next
[/CODE]

It's saying timer to me. Declare a global variable for an index. On the tick increment the index, select the next one on the list with it and load.
