Version 2.0 of our very own spell checking component already set new standards in spell checking performance and accuracy. For 7 months, the TX Spell .NET team has been working on improvements and fantastic new features coming in version 3.0 that we plan to simship with the new TX Text Control release.

I thought to give you a quick overview of what we did and what you can expect.

Suggestion Quality

Version 2.0 delivered very good quality in suggestion results for misspelled words. The team did a great job on doing research on how to improve the suggestions even more. The goal was to have the desired suggestion of the misspelled word ranked at position 1 or 2 in the list of suggestions in more than 90% of all cases. We analyzed internal chat protocols and loads of test documents for misspelled words and typical typos. The distance between the keys on the currently used keyboard is measured and the results are evaluated and rated. Based on our huge collection of test documents with thousands of typos and misspelled words, our engineers reached a level of 97%.

Event-based Spell Check Dialog

Currently, the spell check dialog is integrated into TX Text Control and can be used in combination with TX Spell .NET. In version 3.0, TX Spell .NET provides a user dialog that can be customized and used with TX Text Control or any other controls such as the RichTextBox, a simple TextBox or a GridView.

Each dialog action fires an event that can be handled based on the used control.

Customized Context Menus

The new GetMenuItems method returns valid MenuItems that can be used to easily fill your own context menu.

This gives the possibility to build a MenuStrip with the most common TX Spell .NET features. Effortlessly, you can create a customizable context menu with the incorrect word, the ranked suggestions and you can define the number of suggestions.

New Events for TX Spell .NET

Version 3.0 provides the following events for several scenarios:

• DictionaryAdded
  Occurs when a dictionary is added to the TXSpellChecker.Dictionaries DictionaryCollection.
• DictionaryRemoved
  Occurs when a dictionary is removed from the TXSpellChecker.Dictionaries DictionaryCollection.
• UserDictionaryWordAdded
  Occurs when a word is added to a user dictionary.
• UserDictionaryWordRemoved
  Occurs when a word is removed from a user dictionary.
• Complete events for all spell check dialog buttons and context menu items.

These are just some of the new and improved features of TX Spell .NET 3.0. Stay tuned to learn more.
