Octal to Binary Conversion in Windows Store App

In this article I am going to describe how to convert octal based number into a binary based number. So first of all I will describe what an octal based number is and what a binary based number is.

Octal Number: A number expressed using the base 8 number system with digits 0 to 7.

Binary Number: A number expressed using the base 2 number with digits 0 and 1.

Use the following procedure to create it.

Step 1

First of all you must create a new Windows Store Application.

Open Visual Studio 2012
"File" -> "New" -> "Project..."
Choose "Template" -> "Visual C#" -> "Window Store app"
Choose "Blank App (XAML)" then rename the application

Step 2

Write the following XAML code in "Mainpage.Xaml" (that is available in Solution Explorer):

<Page

    x:Class="octal_to_binary_app.MainPage"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:local="using:octal_to_binary_app"

    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

    mc:Ignorable="d">

 

    <Grid Background="red">

        <Grid.ColumnDefinitions>

            <ColumnDefinition Width="316*"/>

            <ColumnDefinition Width="256*"/>

            <ColumnDefinition Width="295*"/>

            <ColumnDefinition Width="499*"/>

        </Grid.ColumnDefinitions>

        <Grid.RowDefinitions>

            <RowDefinition Height="78*"/>

            <RowDefinition Height="49*"/>

            <RowDefinition Height="37*"/>

            <RowDefinition Height="40*"/>

            <RowDefinition Height="39*"/>

            <RowDefinition Height="525*"/>

        </Grid.RowDefinitions>

        <TextBlock Text="Octal to binary Converter app" Grid.ColumnSpan="4" Grid.Row="1" Foreground="White" FontSize="20" FontFamily="Arial" TextAlignment="Center" FontWeight="ExtraBold"></TextBlock>

        <TextBlock Text="Entern Octal Number :" FontFamily="Arial" FontSize="15" Foreground="White" Grid.Column="1" Grid.Row="2" Grid.RowSpan="4" FontWeight="ExtraBold"></TextBlock>

        <TextBox x:Name="textbox1" Grid.Column="2" Grid.Row="2" Width="200" HorizontalAlignment="Left" Height="20" VerticalAlignment="Top" />

        <TextBlock Text="Eqivalent binary Number is " FontSize="15" Foreground="White" Grid.Column="1" Grid.Row="3" FontWeight="ExtraBold"></TextBlock>

        <TextBlock x:Name="text1" FontSize="15" Foreground="White" Grid.Column="2" Grid.Row="3" Width="200" HorizontalAlignment="Left" ></TextBlock>

        <Button x:Name="button1" Grid.Column="2" Grid.Row="4" Background="Yellow" Foreground="Black" Width="150" Content="Click" Click="button1_Click" Margin="0,1,0,0"></Button>

        <TextBlock x:Name="error" FontSize="15" Foreground="White" Grid.Column="3" Grid.Row="3" Width="200" HorizontalAlignment="Left"></TextBlock>

    </Grid>

</Page>

Step 3

Now write the following C# code for the button within "Mainpage.Xaml.cs".

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using Windows.Foundation;

using Windows.Foundation.Collections;

using Windows.UI.Xaml;

using Windows.UI.Xaml.Controls;

using Windows.UI.Xaml.Controls.Primitives;

using Windows.UI.Xaml.Data;

using Windows.UI.Xaml.Input;

using Windows.UI.Xaml.Media;

using Windows.UI.Xaml.Navigation;

 

namespace octal_to_binary_app

{

    public sealed partial class MainPage : Page

    {

        public MainPage()

        {

            this.InitializeComponent();

        }

        protected override void OnNavigatedTo(NavigationEventArgs e)

        {

        }

        private void button1_Click(object sender, RoutedEventArgs e)

        {

            string[] octalnum = new string[25];

            int r,i=0;

            int num = Convert.ToInt32(textbox1.Text);

            while (num != 0)

            {

                r = num % 10;

                switch (r)

                {

                    case 0:

                        octalnum[i++]="000";

                        break;

                    case 1:

                  octalnum[i++]="001";

                        break;

                    case 2:

                   octalnum[i++]="010";

                        break;

                    case 3:

                       octalnum[i++]="011";

                        break;

                    case 4:

                        octalnum[i++]="100";

                        break;

                    case 5:

                        octalnum[i++]="101";

                        break;

                    case 6:

                        octalnum[i++]="110";;

                        break;

                    case 7:

                        octalnum[i++]="111";

                        break;

                    default:

                        {

                            error.Text = "Invalid octal number";

                            textbox1.Text = "";

                            goto ax;

                        }                                                                     

                }

                num = num / 10;

            }

 

            for (int j = i-1; j >=0; j--)

            {

                text1.Text+= octalnum[j];

            }

            ax: { }

            }       

    }

}

Step 4

Now "Run" your app.
