        hh = totalsec / 3600
        totalsec = totalsec - (hh * 3600)
        mm = totalsec / 60
        totalsec = totalsec - (mm * 60)
        ss = totalsec

        ' totalsec = totalsec - 1
        timercount = timercount - 1
        temp = timercount
        hh = temp / 3600
        Label1.Text = hh.ToString
        temp = temp - (hh * 3600)
        mm = temp / 60
        Label2.Text = mm.ToString

I am not sure if you were able to get anything accomplished from the posted link,
but I could not figure out what a Label.Caption is.:D

I hope this is a little more up to date.

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Button1.Text = "Start"
        Timer1.Interval = 1000 '// tick every second.
        '// textbox1 = Hours, textbox2 = Minutes, textbox3 = Seconds
        TextBox1.Text = "0" : TextBox2.Text = "0" : TextBox3.Text = "0"
     End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If Timer1.Enabled = False Then
            Timer1.Start()
            Button1.Text = "Stop"
        Else
            Timer1.Stop()
            Button1.Text = "Start"
        End If
    End Sub

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        If TextBox1.TextLength < 2 Then TextBox1.Text = "0" & TextBox1.Text '// format from "0" to "00"
        '// verify Hours.
        If TextBox1.Text > "00" And TextBox2.Text = "00" Then
            TextBox1.Text -= 1
            TextBox2.Text = "60"
        End If
       
        If TextBox2.TextLength < 2 Then TextBox2.Text = "0" & TextBox2.Text '// format from "0" to "00"
        '// verify Minutes.
        If TextBox2.Text > "00" And TextBox3.Text = "00" Then
            TextBox2.Text -= 1
            TextBox3.Text = "60"
        End If
       
        If TextBox3.TextLength < 2 Then TextBox3.Text = "0" & TextBox3.Text '// format from "0" to "00"
        '// verify Seconds.
        If TextBox3.Text > "00" Then TextBox3.Text -= 1
       
        '// disable Timer.
        If TextBox1.Text = "00" And TextBox2.Text = "00" AndAlso TextBox3.Text = "00" Then
            Timer1.Enabled = False
            MsgBox("Can I stop counting now?  :)", MsgBoxStyle.Information)
            Button1.Text = "Start"
        End If
    End Sub
End Class
