TX Spell

TX Spell .NET is a very powerful spell checking engine with a tight integration into the document editors from Text Control including ASP.NET, Angular and Windows Forms. It provides fully-featured UI elements including dialog boxes and context menus when connected to a Text Control instance.

Non-Visual Spell Engine

But the product also includes the non-visual component

&#9584; TX Spell .NET for Windows Forms &#9584; Proofing Namespace &#9584; TXSpell Class The TXSpell class provides properties and methods with spell checking features. " data-tippy-interactive="true" data-tippy-placement="bottom" data-tooltip-width="wide"

>TXSpell that can be used for background processing. This sample shows how to use this class to create a spell checking Web API using ASP.NET Core.

Implementing the Web API Controller

The sample implements the Web API controller SpellController :

[Route("api/[controller]")] [ApiController] public class SpellController : ControllerBase {

} This controller implements 4 endpoints:

Check CreateSuggestions CreateSynonyms DetectLanguageScopes

The following code shows the implementation of the Check method that accepts the Text to be checked and an optional language identifier:

[HttpGet] [Route("Check")] public List Check(string text, string language = "en_US") { if (text == null) return null;

// create a new spell checking engine TXTextControl.Proofing.TXSpell spell = new TXTextControl.Proofing.TXSpell(); spell.Create();

TXTextControl.Proofing.OpenOfficeDictionary dict = new OpenOfficeDictionary(@"Dictionaries\en_US.dic"); spell.Dictionaries.Add(dict);

spell.Check(text, new System.Globalization.CultureInfo(language));

List lIncorrectWords = new List ();

var incorrectWords = spell.IncorrectWords;

if (incorrectWords == null) return null;

foreach (IncorrectWord word in incorrectWords) { lIncorrectWords.Add(new IncorrectWordModel() { Text = word.Text, Index = word.Index, IsDuplicate = word.IsDuplicate, Length = word.Length, Start = word.Start }); }

return lIncorrectWords; } In the method Check , a new instance of the spell checker is created and a dictionary is loaded and added to the available dictionaries using the &#9584; TX Spell .NET for Windows Forms &#9584; Proofing Namespace &#9584; DictionaryCollection Class &#9584; Add Method Adds objects of the type Dictionary to the collection and validates them for spell checking and suggestion operations. " data-tippy-interactive="true" data-tippy-placement="bottom" data-tooltip-width="wide"

>Dictionaries. Add method.

The given Text is checked using the

&#9584; TX Spell .NET for Windows Forms &#9584; Proofing Namespace &#9584; TXSpell Class &#9584; Check Method Checks text for spelling errors and fills the IncorrectWordCollection at TXSpell.IncorrectWords with all incorrect words. " data-tippy-interactive="true" data-tippy-placement="bottom" data-tooltip-width="wide"

>Check method and the results are returned as a list of IncorrectWords .

Calling from JavaScript

On the JavaScript side, the endpoint is called using a jQuery ajax call:

async function check(text, language = "en_US") { var serviceURL = "api/spell/check?text=" + text + "&language=" + language; return await callEndpoint(serviceURL); } async function callEndpoint(serviceURL) { return new Promise(resolve => { $.ajax({ type: "GET", url: serviceURL, contentType: 'application/json', success: successFunc, error: errorFunc });

function successFunc(data, status) { resolve(data); }

function errorFunc(data) { throw "Request failed. Please try again later."; } }); } The spell checking functions are encapsulated in a private scope and exposed as properties in the TXSpell JavaScript object. This way, the check method can be called like this in the sample:

async function checkText() { // call the check method var results = await TXSpell.check(document.getElementById('textbox').textContent);

// check console for details console.log(results); var consoleText = "";

// loop through the results and return the text results.forEach(function (element) { consoleText += " Misspelled: " + element.text + "

"; });

document.getElementById('results').innerHTML = consoleText; } On a button click, the function checkText is called:
