Hi, I have a WPF xaml file and I’d like to execute it using IronRuby. I know I can use the System::Windows::Markup::XamlReader.parse method, but is there another way? Using the XamlReader class makes registering events, for example, kind of an irritating task. Thanks, Shay. ---

Yes, there is a ‘Wpf.rb’ in your \Samples\Tutorial directory (This should exist for you if you have a source copy, or the regular 0.6 release) This adds a number of helpers to make working with XAML easier. I haven’t looked at it extensively, but I’d say you can probably learn what is doing by running the wpf tutorial in that dir, and following the source. Look for the “load” methods associated with xaml to get an idea of what helpers are added. Also, if you are trying to do something simple, and the XAML is actually getting in the way, Thibaut Barrère’s “magic” looks to be a very nice DSL for this: > **[GitHub - thbar/magic: IronRuby sugar for WPF, Silverlight and Windows Forms.](https://github.com/thbar/magic/tree/master)** > > master ---

I was looking through the mailing list archives for unanswered mails … eek, sorry Shay! Well, if you still have this question … You can also load XAML with System::Window::Application.LoadComponent: # This loads “foo.xaml” into the “canvas” variable include System include System::Windows include System::Windows::Controls canvas = Canvas.new Application.load\_component canvas, Uri.new(“foo.xaml”, UriKind.relative) This only works when foo.xaml has a x:Class equal to the type passed to the first arg to load\_component, like x:Class=“System.Windows.Controls.Canvas”. ~Jimmy ---

I have load\_component.rb: require ‘PresentationFramework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35’ require ‘PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35’ require ‘WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35’ include System include System::Windows include System::Windows::Controls canvas = Canvas.new Application.load\_component(canvas, Uri.new(“foo.xaml”, UriKind.relative) ) I have my foo.xaml file in the same location as the ruby script above. When I run the script with “ir load\_component.rb” I get error: PresentationFramework:0:in `GetStreamCore': Cannot locate resource 'foo.xaml'. (IOError) from WindowsBase:0:in`GetStream’ from WindowsBase:0:in `GetStream' from PresentationFramework:0:in`LoadComponent’ from loadcomponent.rb:0 Where should I put the foo.xaml for the script above to find it? Only examples I found from Application.LoadComponent from MSDN were using relative URI:s referring to XAML-files embedded in some assembly. I want to load a XAML-file on a disk however. XamlReader.Load is not enough for me since I need to have custom classes created with the xaml:class="…" attribute. Robert B.
