How To Programming Timer Component With Visual Basic .NET

Infrequently You may do programming with timer. I just make metronome software with timer on visual basic 2010. I use my metronome software to make speed exercise to my guitar lesson.

Put 3 label, 2 textbox, 2 button, 1 picturebox on form and 1 timer component

Here it is the design form:

Here it is complete code for metronome software

Public Class Form1

    Private i As Integer

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

        If i >= txtInterval.Text Then i = 0

        i = i + 1

        Label1.Text = i

        Beep()

    End Sub

    Private Sub btnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click

        If txtSecond.Text <> "" And txtInterval.Text <> "" Then

            i = 0

            Timer1.Interval = txtSecond.Text * 1000

            Timer1.Start()

        Else

            MsgBox("Fill Second and Interval", MsgBoxStyle.Critical, "Error")

        End If

    End Sub

    Private Sub btnStop_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStop.Click

        Label1.Text = 0

        Timer1.Stop()

    End Sub

End Class
