2. First I opened a called a SaveFile dialog to get a file path. I then initialized a StreamWriter and used StreamWriter.Write(Textbox.Text) to write to the file.

I then closed the stream using StreamWriter.Close()

3. Yes, I used a for loop to write the listbox into a file. You can write a for loop to write every item of the listbox from 0 until listbox.items.count . This code will work for any length listbox and is much more condensed than if I had chosen not to use a for loop.

4. Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        dlgSave.ShowDialog()
        Dim sW As IO.StreamWriter
        If dlgSave.FileName() <> "" Then
            sW = IO.File.CreateText(dlgSave.FileName)

            Dim i As Integer

            For i = 0 To ListBox1.Items.Count - 1
                sW.WriteLine(ListBox1.Items.Item(i))
            Next i

            sW.Close()
        End If
    End Sub

        Dim i
        Dim TC As Double
        For i = 0 To 11
            TC += ListBox1.Items.Item(i).ToString.Substring(ListBox1.Items.Item(i).ToString.IndexOf("$")) * (-i + 12)
        Next i
        Return Format(TC, "currency")

    End Function
