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.

For a video version of this topic, see Tutorial 2: Create a Maze in Visual Basic - Video 5 or Tutorial 2: Create a Maze in C# - Video 5.

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();
   }
