C++ Update logs from website into game launcher

[Joriku]

Hi,
I am trying to get an update-log box into my current game-launcher which is built with c++.
I've been stuck for a little trying to figure this out, google search after search.
It's currently inside XAML

<Grid>
        <Image Stretch="UniformToFill" Source="images/LauncherBackground.png"/>
        <TextBlock Name="VersionText" VerticalAlignment="Bottom" HorizontalAlignment="Right" FontSize="20" Foreground="White" Margin="0, 0, 5, 0"/>
        <Button Name="PlayButton" Content="Checking For Updates" Click="PlayButton_Click" Height="60" FontSize="28" FontWeight="Bold" Foreground="#DDFFFFFF" Margin="0, 0, 0, 15" VerticalAlignment="Bottom" HorizontalAlignment="Center" MinWidth="150" Background="#FFFF9700" Padding="10,1,10,1"/>
        <Grid>
            <TextBlock Margin="23,176,747,119" Background="#FFFF9700"/>
            <TextBlock Height="53" FontSize="36" FontWeight="Bold" Foreground="#DDFFFFFF" Margin="55,117,0,0" VerticalAlignment="Top" HorizontalAlignment="Left" MinWidth="150" Background="#FF46099E" Padding="10,1,10,1" Text="Update Logs" FontFamily="Segoe Script" FontStyle="Normal" RenderTransformOrigin="0.484,1.239"/>
        </Grid>
        <TextBox Height = "246" 
         HorizontalAlignment = "Left" 
         Margin = "33,184,0,0" 
         Name = "textBox1"  
         VerticalAlignment = "Top" 
         Width = "290" Background="#FF2C2B2B" />
    </Grid>

Trying to get it..
