        Timer1.Enabled = False
        TextBox1.Text = "0" : TextBox2.Text = "0" : TextBox3.Text = "0"

        Button6.Hide()
    End Sub


    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
     
        If Timer1.Interval <> 100 Then Timer1.Interval = 100
        If DateTime.Now > TimeEnd Then
            TextBox5.Text = "Time End"
            Timer1.Stop()

        Else

            If isStop = False And isPause = False Then
                foo = TimeEnd - DateTime.Now
                TextBox5.Text = String.Format("{0:D2}:{1:D2}:{2:D2}", _
                                              foo.Hours, foo.Minutes, foo.Seconds)

            End If
            TextBox6.Text = TimeStart.ToString("hh:mm" & " " & "tt")

        Timer1.Interval = 1
        Timer1.Start()
        isStop = False

    End Sub


    Private Sub TextBox5_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox5.TextChanged

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
       'STOP
        isStop = True
        TimeStop = DateTime.Now
       ' form02.PressStop = True

        End If
    End Sub
End Class

im working on a stop watch that can set a time then do a countdown, and do a ascending count
.im kind of a messy when it comes to this thing hope u understand the code. what im trying to do now is  to make a PAUSE and RESUME button for this code. i've tried using on the Pause button timer1.enabled = false and on the RESUME button Pause button timer1.enabled = true. it does pause the time and resumes it,but for example the timer is counting down and i pause it at 5:33, and resume it after 7 seconds, the timer then resumes at 5:40, what i want to do is to make it resume from the time that i pause it, in my example i want it to resume from 5:33. hope you can help me. thanks in advance
