Silverlight Spell Checker Component

This free Silverlight Spell Checker component allows you to apply real-time spell checking functionality to your Silverlight applications with the minimum of code.  Dictionaries are not supplied, however they can be freely downloaded and used with this component.

To use the Spell Checker you will need to add a reference to Liquid.Components.dll in your project.


How to Use the Spell Checker Component

To demonstrate the Spell Checker component we have a single TextBox and a Button.  The Button Click event handler takes the textbox text and runs it through the spell checker and populates a ListBox with spelling suggestions if the input word was not found in the dictionary.  In your Silverlight XAML:

<UserControl x:Class="SpellChecker.Page"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Width="400" Height="300">
    <Canvas>
        <TextBox x:Name="word" Canvas.Left="5" Canvas.Top="10" Width="200" />
        <Button Content="Check" Canvas.Left="220" Canvas.Top="10" Click="Button_Click" />
        <TextBlock Canvas.Left="5" Canvas.Top="40" Text="Suggestions" FontSize="25" />
        <ListBox x:Name="suggestions" Canvas.Left="5" Canvas.Top="75" Width="200" Height="100" />
    </Canvas>
</UserControl>


In your C# code behind file we handle the button click event and make the call to CheckWord() which returns true to indicate a correct word.  If the word is incorrect we call GetSuggestions() which returns a List<string> collection of spelling suggestions which we use to simply populate our ListBox.

namespace SpellChecker
{
    public partial class Page : UserControl
    {
        private Liquid.Components.SpellChecker _spellChecker;

        public Page()
        {
            InitializeComponent();

            _spellChecker = new Liquid.Components.SpellChecker((this.GetType().Assembly.GetManifestResourceStream("SpellChecker.dictionary.en-US.dic")));
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            bool success = _spellChecker.CheckWord(word.Text);
            List<string> suggest;

            if (!success)
            {
                suggest = _spellChecker.GetSuggestions(word.Text);
                suggestions.Items.Clear();

                foreach (string s in suggest)
                {
                    suggestions.Items.Add(new ListBoxItem() { Content = s });
                }
            }
        }
    }
}

Hi Bart,


Sure, the web.config setting has nothing to do with this uploader as the component uses web services to upload the file in chunks.  I imagine the first chunk is being transmitted but not the rest.


Firstly, are you using the same web service provided with the demo?  Does your Upload() web service method return the string "ok", this is important to ensure the uploader sends all packets of information.


Thanks!

Hi Lance,


I have modified the demo and integrated it with a test website.  This can be downloaded from the demos page as usual and should help point you in the right direction.


Thanks!

Okay, Passing data from a memory stream rather than the file dialog as in my example will work just the same.  I assume you have placed a breakpoint on your web service when testing and it is never called?


Looking at your web service it looks fine and if it is never called suggests the problem is with this Silverlight client and quite possibly the memory data stream, is it possible for you to post/email your full Silverlight or at least a test application that reproduces the problem?


Thanks!

Hi,


That demo is the fully running application code, the web services simply need to be added to your website in the usual manner.  The URL in the Silverlight demo code needs to be changed to the URL of your website and it should work.


Ideally you need IIS, but you can use Visual Studio to host the website but you will need to change the URL reference to whatever Visual Studio gives your website including any port number.


Thanks!

Hi Dan.

Confused by the fiddler informations, I had some difficulties to fix the problem. Well, the problem is gone. Creating the directory documents/0002, it works fine!

thx for your patience.
