        With ListBox1.Items '// FOR.TESTING
        End With
    End Sub

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        If Not TextBox1.Text = "" Then
            With ListBox2.Items
                For Each itm As String In ListBox1.Items
                    If getCoolHttp(itm).Contains(TextBox1.Text) Then .Add(itm) '// get page source and check for the search.keyword.

        End If
    End Sub
    Private Function getCoolHttp(ByVal selCoolUrl As String) As String
        Me.Cursor = Cursors.WaitCursor
            Dim myResponse As Net.HttpWebResponse = Net.HttpWebRequest.Create(selCoolUrl).GetResponse '// connect.
            Dim myStream As IO.Stream = myResponse.GetResponseStream() '// get.
            Dim myReader As New IO.StreamReader(myStream) '// read.
            Dim webContent As String = myReader.ReadToEnd
            myReader.Close() : myStream.Close() : myResponse.Close()
            Me.Cursor = Cursors.Default
            Return webContent
        Catch ex As Exception
            Me.Cursor = Cursors.Default

.a few(2+)BackGroundWorkers (depending on user's p.c. net.connection and system.specs), can run the search.results on separate threads, Not just one As default for a WindowsApplication.

Not watching video, stop watching you.


your code worked.it's ok. But. wery slow.I want to post & get very fast.:(

Use Threading and run those HTTPs on separate threads.

please give me code or example pro.

Another suggestion: purchase a web.server, update web content frequently on it(your content), and use that for quicker results.

Hope this helps.

hmm ok.Try to your code.But you are really answer friendly me.very thank you.
