Step 7: Add Code to Your Form to Play Sounds

You are now ready to add a second SoundPlayer, and then add a method to call each SoundPlayer.

To play sounds

  1. Start by adding a second SoundPlayer to play the Windows Tada sound. Your game will play this sound when the player reaches the Finish label.

    Public Class Form1

    ' This SoundPlayer plays a sound whenever the player hits a wall.
    Private startSoundPlayer = New System.Media.SoundPlayer("C:\Windows\Media\chord.wav")

    ' This SoundPlayer plays a sound when the player finishes the game.
    Private finishSoundPlayer = New System.Media.SoundPlayer("C:\Windows\Media\tada.wav")

    Public Sub New()
        ' This call is required by Windows Forms Designer.
        InitializeComponent()
        ' Add any initialization after the InitializeComponent() call.
        MoveToStart()
    End Sub

    public partial class Form1 : Form
{
    // This SoundPlayer plays a sound whenever the player hits a wall.
    System.Media.SoundPlayer startSoundPlayer = new System.Media.SoundPlayer(@"C:\Windows\Media\chord.wav");

    // This SoundPlayer plays a sound when the player finishes the game.
    System.Media.SoundPlayer finishSoundPlayer = new System.Media.SoundPlayer(@"C:\Windows\Media\tada.wav");

    public Form1()
    {
        InitializeComponent();
        MoveToStart();
    }

  2. Both SoundPlayers are now added to your form. Add a Play() method to call the SoundPlayer to play the sound at the appropriate time. You want a sound to play when the user hits a wall. So add the statement startSoundPlayer.Play(); to your MoveToStart() method. Remember to update the comment. The final method looks like the following.

    ''' <summary>
''' Play a sound, then move the mouse pointer to a point 10 pixels down and to 
''' the right of the starting point in the upper-left corner of the maze.
''' </summary>
''' <remarks></remarks>
Private Sub MoveToStart()
    startSoundPlayer.Play()
    Dim startingPoint = Panel1.Location
    startingPoint.Offset(10, 10)
    Cursor.Position = PointToScreen(startingPoint)
End Sub

    /// <summary>
/// Play a sound, then move the mouse pointer to a point 10 pixels down and to 
/// the right of the starting point in the upper-left corner of the maze.
/// </summary>
private void MoveToStart()
{
    startSoundPlayer.Play();
    Point startingPoint = panel1.Location;
    startingPoint.Offset(10, 10);
    Cursor.Position = PointToScreen(startingPoint);
}

  3. Add the statement finishSoundPlayer.Play(); to the Finish label MouseEnter event handler. Remember to update the comment, because you're changing the code, as follows.

    Private Sub finishLabel_MouseEnter() Handles finishLabel.MouseEnter
    ' Play a sound, show a congratulatory MessageBox, then close the form.
    finishSoundPlayer.Play()
    MessageBox.Show("Congratulations!")
    Close()
End Sub

    private void finishLabel_MouseEnter(object sender, EventArgs e)
{
    // Play a sound, show a congratulatory MessageBox, then close the form.
    finishSoundPlayer.Play();
    MessageBox.Show("Congratulations!");
    Close();
}
