Step 6

Once in the Code View for Library.cs the following should be entered:

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using Windows.Storage.Streams;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;

public class Library
{
    private Dictionary<string, double> notes = new Dictionary<string, double>()
    {
        { "C", 261.6 }, { "C#", 277.2 }, { "D", 293.7 },
        { "D#", 311.1 } , { "E", 329.6 }, { "F", 349.2 },
        { "F#", 370.0 }, { "G", 392.0 }, { "G#", 415.3 },
        { "A", 440.0 }, { "A#", 466.2 }, { "B", 493.9 }
    };

    private void play(double note)
    {
        MediaElement playback = new MediaElement();
        IRandomAccessStream stream = new InMemoryRandomAccessStream();
        BinaryWriter writer = new BinaryWriter(stream.AsStream());
        int formatChunkSize = 16;
        int headerSize = 8;
        short formatType = 1;
        short tracks = 1;
        int samplesPerSecond = 44100;
        short bitsPerSample = 16;
        short frameSize = (short)(tracks * ((bitsPerSample + 7) / 8));
        int bytesPerSecond = samplesPerSecond * frameSize;
        int waveSize = 4;
        int data = 0x61746164;
        int samples = 88200 * 4;
        int dataChunkSize = samples * frameSize;
        int fileSize = waveSize + headerSize + formatChunkSize + headerSize + dataChunkSize;
        double frequency = note * 1.5;
        writer.Write(0x46464952); // RIFF
        writer.Write(fileSize);
        writer.Write(0x45564157); // WAVE
        writer.Write(0x20746D66); // Format
        writer.Write(formatChunkSize);
        writer.Write(formatType);
        writer.Write(tracks);
        writer.Write(samplesPerSecond);
        writer.Write(bytesPerSecond);
        writer.Write(frameSize);
        writer.Write(bitsPerSample);
        writer.Write(data);
        writer.Write(dataChunkSize);
        for (int i = 0; i < samples / 4; i++)
        {
            double t = (double)i / (double)samplesPerSecond;
            short s = (short)(10000 * (Math.Sin(t * frequency * 2.0 * Math.PI)));
            writer.Write(s);
        }
        stream.Seek(0);
        playback.SetSource(stream, "audio/wav");
        playback.Play();
    }

    private void add(Grid grid, int column)
    {
        Button button = new Button()
        {
            Height = 80,
            Width = 20,
            FontSize = 10,
            Padding = new Thickness(0),
            Content = notes.Keys.ElementAt(column)
        };
        button.Click += (object sender, RoutedEventArgs e) =>
        {
            button = (Button)sender;
            int note = Grid.GetColumn(button);
            play(notes[notes.Keys.ElementAt(note)]);
        };
        button.SetValue(Grid.ColumnProperty, column);
        grid.Children.Add(button);
    }

    private void layout(ref Grid Grid)
    {
        Grid.Children.Clear();
        Grid.ColumnDefinitions.Clear();
        Grid.RowDefinitions.Clear();
        // Setup Grid
        for (int Column = 0; (Column < notes.Count); Column++)
        {
            Grid.ColumnDefinitions.Add(new ColumnDefinition());
            add(Grid, Column);
        }
    }

    public void New(Grid grid)
    {
        layout(ref grid);
    }
}

It should then appear as such:

2015-sound-game-library

Step 7

From the Solution Explorer select MainPage.xaml

2015-mainpage-library

Step 8

Select from the Menu, View then Designer

2015-view-designer

Step 9

The Design View will be displayed along with the XAML View and in this above <Grid Background=”{ThemeResource ApplicationPageBackgroundThemeBrush}”> enter the following XAML:

<Page.BottomAppBar>
	<AppBar IsOpen="True" IsSticky="True">
		<StackPanel Orientation="Horizontal">
			<AppBarButton Icon="Page" Label="New" Click="New_Click"/>
		</StackPanel>
	</AppBar>
</Page.BottomAppBar>

While still in the XAML View below <Grid Background=”{ThemeResource ApplicationPageBackgroundThemeBrush}”> enter the following XAML:

<Grid Name="Display" HorizontalAlignment="Center" Height="300" Width="300"/>

It should appear as such:

2015-sound-game-mainpage-xaml

Step 10

Select from the Menu, View then Code

2015-view-code

Step 11

Once in the Code View below the public MainPage() { … } the following should be entered:

public Library Library = new Library();

private void New_Click(object sender, RoutedEventArgs e)
{
	Library.New(Display);
}

It should then appear as such:

2015-sound-game-mainpage-code

Step 12

That completes the Universal Windows Application so Save the Project then select the Debug and Local Machine option to run the Application

2015-local-machine

Step 13

Once the Local Machine has started the Application should then appear

2015-sound-game-simulator-run

Step 14

After the Application has started running use New to start then can Play sounds by tapping the buttons in the Application

2015-sound-game-simulator-ran

Step 15

To Exit the application select Stop Debugging in Visual Studio Community 2015

2015-stop

Step 16

Another option is to run as a Windows 10 Mobile application, select Debug and select Emulator 10.0.10586.0 WVGA 4 inch 512MB option to run the Application

2015-emulator

Step 17

Once the Emulator has started the Application should then appear

2015-sound-game-emulator-run

Step 18

After the Application has started running use New to start then can Play sounds by tapping the buttons in the Application

2015-sound-game-emulator-ran

Step 19

To Exit the application select Stop Debugging in Visual Studio Community 2015

2015-stop
