Public Class Form1
    Dim Hours As Integer
    Dim Minutes As Integer
    Dim Seconds As Integer
    Dim Time As Date

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        Timer1.Enabled = False
        If (Format$(Time, "hh") & ":" & Format$(Time, "nn") & ":" & Format$(Time, "ss")) <> "00:00:00" Then 'Counter to continue loop until 0
            Time = DateAdd("s", -1, Time)
            Label1.Visible = False
            Label1.Text = Format$(Time, "hh") & ":" & Format$(Time, "nn") & ":" & Format$(Time, "ss")
            Label1.Visible = True
            Timer1.Enabled = True
        Else
            'Turn off timer, set off alarm, and enable reset.
            Timer1.Enabled = False
            Beep()
            Beep()
            Button3.Enabled = True
        End If
    End Sub

    Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
        Mydisplay()
    End Sub

    Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged
        Mydisplay()
    End Sub

    Private Sub TextBox3_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox3.TextChanged
        Mydisplay()
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Set timer interval and varibles
        Timer1.Interval = 1000
        Hours = 0
        Minutes = 0
        Seconds = 0
        Time = 0
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Timer1.Enabled = True
    End Sub
    Private Sub Mydisplay()
        'This code is common to all three text boxes so I
        'put it in it's own sub.

        'Extract the numbers from the text boxes by using
        'the Val() statement.
        Hours = Val(TextBox1.Text)
        Minutes = Val(TextBox2.Text)
        Seconds = Val(TextBox3.Text)
        'Convert variables to time format
        Time = TimeSerial(Hours, Minutes, Seconds)
        'Display the converted time variable in label 1
        Label1.Text = Format$(Time, "hh") & ":" & Format$(Time, "nn") & ":" & Format$(Time, "ss")
    End Sub
End Class
