Not quite sure what you mean. Could you post the code you have already?

I'm currently seeing loops in programming classes, so I might be able to help you.
Problem is, I don't really understand what you mean either.

check this video tutorial about loops in c# its almost the same in vb.net, might help you:

You can use the StreamWriter.Peek(system.io.streamwriter) method to load the files into the first list box. Peek() will return -1 if the next line to be read is EOF. This could be coupled with a do until loop to fill your first listbox with the "raw" data.

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Form1.Load
        Dim objStreamReader As System.IO.StreamReader
        Dim strLineRead As String
        objStreamReader = IO.File.OpenText("path")
        Do Until objStreamReader.Peek() = -1
            strLineRead = objStreamReader.ReadLine()
            ListBox1.Items.Add(strLineRead)
        Loop
    End Sub

As for as everything else in your post, I can't really advise any more than anyone else without you elaborating first.
