Forum: IronRuby silverlight 3 question

Hi
I have a hard time understanding why the following won't work.  I 
started
with the following xaml:

<UserControl x:Class="System.Windows.Controls.UserControl"
 xmlns="http://schemas.microsoft.com/client/2007"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

  <Grid x:Name="layout_root" Background="White">
    <TextBlock x:Name="message" FontSize="10" />
  </Grid>

 </UserControl>

and in the initialize method of App I've got the following code

@root = Application.current.load_root_visual(UserControl.new, 
"app.xaml")
request = Net::WebClient.new
request.download_string_completed do |sender, args|
      @root.find_name("message").text = "Completed"
end
request.download_string_async Uri.new("http://google.com")


This works but as you can see nothing interesting happens except for 
that
download_string_completed is called because the message textbloc shows
Completed

@root = Application.current.load_root_visual(UserControl.new, 
"app.xaml")
request = Net::WebClient.new
request.download_string_completed do |sender, args|
      @root.find_name("message").text = *args.result*
end
request.download_string_async Uri.new("http://google.com")

But as soon as I ask the args for the result nothing happens anymore. it
must be an exception somewhere but I have no idea as to where I can find 
the
exception or stacktrace because all it does is show me a blank page with 
all
layout removed and the IronRuby Console in the bottom is still there but 
it
is disabled too.

So how do I get to that error?

I've tried to do the same in C#

           var wc = new WebClient();
           wc.DownloadStringCompleted += (s, e) => Message.Text = 
e.Result;
           wc.DownloadStringAsync(new Uri("http://google.com"));

Which actually gives me the same result but I do get to see the error 
once
in a while. It's saying something about SecurityException.
So I went on and tried fetching the page it with a webrequest

var wr = WebRequest.Create("http://google.com");
            wr.BeginGetResponse(ar =>
                                    {
                                        var req = 
(WebRequest)ar.AsyncState;
                                        var resp = 
req.EndGetResponse(ar);
                                        using(var sr = new
StreamReader(resp.GetResponseStream()))
                                        {
                                            var result = sr.ReadToEnd();
                                            Message.Text = result;
                                        }
                                    }, null);


This last approach also fails because AsyncState is null.
Have I lost my mind? Am I doing something wrong or is it Silverlight?

k rookie mistake I guess. google.com obviously doesn't have a
crossdomainpolicy.xml file in placeUsing the
flickr url I wanted to get in the first place helps a lot.

Yeah, the clientaccesspolicy.xml file requirement makes these things a 
bit annoying. This is why most JavaScript APIs are .js files hosted on 
the domain so they can make requests back to the domain.

What kept me most busy was the fact that I never got any error messages
displayed to me, which left as only option to comment out code until i 
could
see something again.
I have a xaml that shows a background color. When an error occurs in the
ruby code the background would become white. the REPL console doesn't 
accept
any input anymore and I have no clue as to what's going on.  So 
sometimes I
could write the code in C# and see why things were failing.

I must be missing something as I do have the following as params 
debug=true,
console=true

<param name="initParams" value="debug=true, reportErrors=errorLocation,
console=true" />

So how do I see errors when they occur?

Is the Silverlight control taking up the whole HTML window? If so, make 
sure to do <params name="windowless" value="true" /> so the error 
console shows up over the Silverlight app.

If this doesn’t seem to fix it, mind sending me a repro?
