Hi
Here is a simplified example.
' Form1 with Label1 and Timer1
Option Strict On
Option Explicit On
Public Class Form1
Dim files() As String
Dim Pause As Integer = 5
Dim pointer As Integer = 0
' set to required folder
Dim folder As String = My.Computer.FileSystem.SpecialDirectories.Desktop
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
files = IO.Directory.GetFiles(folder, "*.txt")
Timer1.Enabled = True
End Sub
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
Timer1.Interval = Pause * 1000
Label1.Text = IO.File.ReadAllText(files(pointer))
pointer += 1
If pointer > files.Count - 1 Then pointer = 0
End Sub
End Class
