[Ironruby-core] silverlight 3 question

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?

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?

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.

k rookie mistake I guess. google.com<http://google.com> obviously doesn't have a crossdomainpolicy.xml file in place

Using the flickr url I wanted to get in the first place helps a lot.

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?

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?
