Ja tiež vôbec nie som si istý, či viem, čo vlastne chcete, ale ak Vám to pomôže?...

Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        VScrollBar1.Value = VScrollBar1.Maximum
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        VScrollBar1.Value = VScrollBar1.Minimum
    End Sub
End Class

alebo

Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        TextBox1.Multiline = True
        TextBox1.ScrollBars = ScrollBars.Vertical
    End Sub
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        TextBox1.SelectionStart = 0
        TextBox1.ScrollToCaret()
    End Sub
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        TextBox1.SelectionStart = TextBox1.TextLength + 1
        TextBox1.ScrollToCaret()
    End Sub
End Class
