Dim oauth_token = ""
Dim oauth_token_secret = ""
Dim oauth_consumer_key = ""
Dim oauth_consumer_secret = ""
' oauth implementation details
Dim oauth_version = "1.0"
Dim oauth_signature_method = "HMAC-SHA1"
' unique request details
Dim oauth_nonce = Convert.ToBase64String(New ASCIIEncoding().GetBytes(DateTime.Now.Ticks.ToString()))
Dim timeSpan = DateTime.UtcNow - New DateTime(1970, 1, 1, 0, 0, 0, _
0, DateTimeKind.Utc)
Dim oauth_timestamp = Convert.ToInt64(timeSpan.TotalSeconds).ToString()

Dim resource_url = "https://api.twitter.com/1.1/followers/ids.json"
Dim screen_name = "SimplyBenGenius"
Dim count = "5000"
Dim cursor = "-1"
' create oauth signature
Dim baseFormat = "count={7}&oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" + "&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}&screen_name={6}"

End Using
' create the request header

Dim authHeader = String.Format(headerFormat, Uri.EscapeDataString(oauth_nonce), Uri.EscapeDataString(oauth_signature_method), Uri.EscapeDataString(oauth_timestamp), Uri.EscapeDataString(oauth_consumer_key), Uri.EscapeDataString(oauth_token), _
Uri.EscapeDataString(oauth_signature), Uri.EscapeDataString(oauth_version))
' make the request
ServicePointManager.Expect100Continue = False
Dim postBody = "screen_name=" + Uri.EscapeDataString(screen_name)
'
Dim postbody2 = "count=" + Uri.EscapeDataString(count)
resource_url += "?" + postBody + "&" + postbody2
Dim request As HttpWebRequest = DirectCast(WebRequest.Create(resource_url), HttpWebRequest)
request.Headers.Add("Authorization", authHeader)
request.Method = "GET"
request.ContentType = "application/x-www-form-urlencoded"
Dim response As WebResponse = request.GetResponse()
Dim responseData As String = New StreamReader(response.GetResponseStream()).ReadToEnd()
RichTextBox1.Text = responseData
this what i've got for with the cursors addition but with no luck..

any advice would be great, it might be a simple fix but i just can't seem to see it..
