Google spellcheck service

[Roland]

Wasnt this implemented recently? I even had information on how to put it in -

Create a GoogleSpellCheckProvider class that implements the ISpellCheckProvider.

Set SpellCheckProviderTypeName property of RadSpell to = typeof(Telerik.Web.UI.GoogleSpellCheckProvider).AssemblyQualifiedName of compiled GoogleSpellCheckProvider created.

This still works?

Thanks.

Hello Roland,

You should set the AllowAddCustom  property to false too.
A simple example which illustrates how to use GoogleSpellCheckProvider is available here:

Let us know if you have any other questions.

Hi Petio.

Thanks for the reply. Yes, i set that property as well.

The next problem we had was our company has some issues with letting Google be the dictionary as well so we wanted to spellcheck locally but send mistaken words to the service instead as it gives better suggestions.

So I tweaked the GoogleSpellCheckProvider class as follows -

public GoogleSpellCheckProvider(SpellChecker checker)
        {
            this.checker = checker;
            this.textWords = checker.TextWords;
            this._language = checker.DictionaryLanguage.Substring(0, 2).ToLower();
            StringBuilder sb = new StringBuilder();

            //create new spellcheck to check words.
            SpellChecker chk = new SpellChecker(HttpContext.Current.Server.MapPath("~/App_Data/RadSpell/"));
            chk.SpellCheckProvider = SpellCheckProvider.PhoneticProvider;
            chk.Text = checker.Text;
            chk.WordIgnoreOptions = checker.WordIgnoreOptions;

            SpellCheckErrors errors = chk.CheckText();

            //append misspelled words instead of ALL the words.
            foreach (SpellCheckError error in errors)
            {
                sb.Append(error.MistakenWord);
                sb.Append(" ");
            }

            //for (int i = 0; i < textWords.Length; i++)
            //{
            //    sb.Append(textWords[i].Word);
            //    sb.Append(" ");
            //}
            this._text = sb.ToString();
            //make Google request
            string uri = BuildUri(this._language);
            byte[] buffer = Encoding.UTF8.GetBytes(get_request(this._text));
            WebClient webClient = new WebClient();
            webClient.Headers.Add("Content-Type", "text/xml");
            byte[] response = webClient.UploadData(uri, "POST", buffer);
            string resultXML = Encoding.UTF8.GetString(response);
            this.parseResultXML(resultXML); //fill the suggestions dictionary
        }

Seems to be working fine. Am I missing anything?

Thanks.

Hi Roland,

Everything in the code provided seems to be fine.
My suggestion is to add try/catch for the code related to the Google SpellCheck service - if you cannot reach Google due to some reason(e.g. missing connectivity), use the already found mistaken words from the Telerik.Web.UI.SpellChecker.

All the best,

Hi Petio.

Did the ISpellCheckProvider get removed from the recent releases?

Thanks.

Hi Roland,

No, it is not. You can see the ISpellCheckProvider is used in the following demo:

Custom Google spellcheck provider.

Hi Rumen.

Thanks for the reply. Just seemed odd that some functionality went down when I upgraded to Q1 2010 for spellcheck and treeview. Upgrading to Q2 2010 fixed a lot of issues.

Thanks.
