    <MenuItem Header="_Bold" IsCheckable="True"
              Checked="Bold_Checked"
              Unchecked="Bold_Unchecked"/>
    <MenuItem Header="_Italic" IsCheckable="True"

</Menu>
<TextBox Name="textBox1" TextWrapping="Wrap"
         Margin="2">

    textBox1.FontWeight = FontWeights.Bold;
}

private void Bold_Unchecked(object sender, RoutedEventArgs e)
{
    textBox1.FontWeight = FontWeights.Normal;
}

private void Italic_Checked(object sender, RoutedEventArgs e)
{
    textBox1.FontStyle = FontStyles.Italic;

private void Italic_Unchecked(object sender, RoutedEventArgs e)

private void IncreaseFont_Click(object sender, RoutedEventArgs e)
{
    if (textBox1.FontSize < 18)
    {
        textBox1.FontSize += 2;
    }
}

private void DecreaseFont_Click(object sender, RoutedEventArgs e)
{
    if (textBox1.FontSize > 10)
    {
        textBox1.FontSize -= 2;
    }
}

Private Sub Bold_Checked(ByVal sender As Object, ByVal e As RoutedEventArgs)
    textBox1.FontWeight = FontWeights.Bold
End Sub

Private Sub Bold_Unchecked(ByVal sender As Object, ByVal e As RoutedEventArgs)
    textBox1.FontWeight = FontWeights.Normal
End Sub

Private Sub Italic_Checked(ByVal sender As Object, ByVal e As RoutedEventArgs)
    textBox1.FontStyle = FontStyles.Italic
End Sub

Private Sub Italic_Unchecked(ByVal sender As Object, ByVal e As RoutedEventArgs)
    textBox1.FontStyle = FontStyles.Normal
End Sub

Private Sub IncreaseFont_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
    If textBox1.FontSize < 18 Then
        textBox1.FontSize += 2
    End If
End Sub

Private Sub DecreaseFont_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
    If textBox1.FontSize > 10 Then
