i want to filter this text

just want to show these items in text box

how to do that any help?

You could do something like this (that works on this very posting):

Imports System.Net
Imports System.IO
Imports System.Text.RegularExpressions

Module Module1

   Sub Main()
      Dim rxIpAndPort As New Regex("(?<ip_and_port>\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}:\d{1,5})")
      Dim wc As New WebClient
      Dim fileInFile As New StreamReader(wc.OpenRead(""))
      Dim arr_strData = fileInFile.ReadToEnd() _
         .Split((Chr(10) + Chr(13) + "<> ") _
         .ToCharArray(), StringSplitOptions.RemoveEmptyEntries) _
         .Where(Function(s) rxIpAndPort.IsMatch(s)) _
         .Select(Function(s) rxIpAndPort.Match(s).Groups("ip_and_port").Value) _
         .Distinct() _

      ' TextBox3.Text = String.Join(Environment.NewLine, arr_strData)
      System.Diagnostics.Debug.WriteLine(String.Join(Environment.NewLine, arr_strData))
   End Sub

End Module

no link involved

i load text in to text box then press 1 button to filter not grabbing from some link

That was just an example. You can parse your text the same way from the text box.
Like TextBox3.Text = TextBox3.Text.Split((Chr(10) ... 'and so on...'

still not understandin

i load text in textbox from 1 text file

then i filter it

in example u showed u grabbing from link

am trying to learn and help my self so new things not understandable for me

Then the first example will work.
Instead of opening a StreamReader to a web page, open that same StreamReader to your text file.
