hola. pretendo hacer una aplicacion para generar partituras vi un ejemplo para controlar beep() pero no se como ejecutarlo desde un formulario. El ejemplo es el siguiente:
Imports System
Imports System.Threading
Public Class Form1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
*** COMO PUEDO EJECUTAR ESTE CODIGO DESDE UN BOTON
End Sub
End Class
' This example demonstrates the Console.Beep(Int32, Int32) method
Class Sample
Public Shared Sub Main()
' Declare the first few notes of the song, "Mary Had A Little Lamb".
Dim Mary As Note() = { _
New Note(Tone.B, Duration.QUARTER), _
New Note(Tone.A, Duration.QUARTER), _
New Note(Tone.GbelowC, Duration.QUARTER), _
New Note(Tone.A, Duration.QUARTER), _
New Note(Tone.B, Duration.QUARTER), _
New Note(Tone.B, Duration.QUARTER), _
New Note(Tone.B, Duration.HALF), _
New Note(Tone.A, Duration.QUARTER), _
New Note(Tone.A, Duration.QUARTER), _
New Note(Tone.A, Duration.HALF), _
New Note(Tone.B, Duration.QUARTER), _
New Note(Tone.D, Duration.QUARTER), _
New Note(Tone.D, Duration.HALF)}
' Play the song
Play(Mary)
End Sub 'Main
' Play the notes in a song.
Protected Shared Sub Play(tune() As Note)
Dim n As Note
For Each n In tune
If n.NoteTone = Tone.REST Then
Thread.Sleep(CInt(n.NoteDuration))
Else
Console.Beep(CInt(n.NoteTone), CInt(n.NoteDuration))
End If
Next n
End Sub 'Play

End Enum 'Tone

'This example produces the following results:
