Converting to ASCII and Binary Code

We will see how to build a WPF application that converts the key pressed to ASCII and binary code.

• First create a simple WPF form.
• Take Four Labels and name then as
• lblKey to show key pressed
• lblChar to show actual character of the key
• lblAscii to show its ASCII value
• lblBinary to show binary value
• and a textbox that will be hidden

Now in the form code as below.

    private void GlassWindow_Loaded(object sender, RoutedEventArgs e)

    {

        textBox1.Focus();

    }

 

    private void GlassWindow_KeyDown(object sender, KeyEventArgs e)

    {

        textBox1.Text = "";

        lblKey.Content = e.Key.ToString();

        lblAscii.Content = "";

        lblBinary.Content = "";

        lblChar.Content = "";

    }

 

    private void textBox1_TextChanged(object sender, TextChangedEventArgs e)

    {

        try

        {

            lblChar.Content = textBox1.Text.ToString();

            lblAscii.Content = Convert.ToUInt16(Convert.ToChar(textBox1.Text));

            lblChar.Content = Convert.ToChar(lblAscii.Content);

            lblBinary.Content = Convert.ToString(Convert.ToByte(lblAscii.Content), 2);

        }

        catch { }

    }

 
Output will be:
