Before going in to my review of Infragistics Spell Check control, and how it compares to other controls I’ve used, I’m going to discuss the importance of spellcheck. If you want to skip down to the review, click here.

Communication getting Relaxed
It is amazing at how lax communication has become. With so many quick methods for communicating, less thought is going in to our communications. As more methods move mainstream, and become part of everyday life, more people are communicating less professionally. As a professional you need to take the time to use proper case, punctuation and spell check. It can be a poor reflection on you and your business if you do not. Even as I type this, Live Writer is constantly underlining misspelt words, forcing me to correct the words before publishing my post. Recently I was tasked with adding Spell Check to a thick client application that has been in development for over 5 years. As soon as it was brought up I thought, “Why didn’t we do this sooner?”. This particular application focuses on transportation maintenance management, and the maintenance managers commented that they want spell check added to work orders, and comments, so that they can correct their spelling before these reports get passed up to corporate. Before, nobody ever thought of who might eventually read their work orders, but as the company pushes more on professionalism, the importance of every communication portraying their skill and dedication to the business, as risen to the surface.
When tasked with adding spell check throughout the application, I first went to Google. I was looking for a free solution spell check component that I could quickly integrate through out the solution. The first suggestion was using Microsoft Word’s Interop to leverage the spell check capabilities behind Microsoft, but I wasn’t thrilled with the prospect of being tied to a 3rd party application. We did have a discussion as to whether or not this was a feasible requirement for our end users to have Microsoft Word installed. Most (if not all) of our users do have Microsoft Word installed, but we were hoping to find a better solution.
Next I discovered NHunspell. This looked very promising. I downloaded the libraries, and started working with it. It looked like it was going to get the job done, but there were a lot of little features that I wanted (red squiggle underline, right click correction options, pop-up replacement, custom dictionary, etc), but would have to build out myself. I was up to the challenge, but could not get over the fact that spell check has been around for so long, that there should be a faster way to implement all of these features. Hopefully one day, someone, will write a nice library based on the free spell check component NHunspell.
Review of Infragistics’ Spell Check Control for WinForms
We use the Infragistics suite of tools within this project currently, but I had forgotten that they have a spell check control. After realizing that we already had a spell check control here at our fingertips, that should already be fully developed, I removed the NHunspell code that I had started, and started down this new path. It was amazingly simple. I added the component as a reference, dragged it to the form, and then enabled it for each of the text boxes that we wanted spell check on. I was shocked at how simple it was. I ran the application, and all of my mistyped words had red squiggles under them.
Pop-up spelling correction was just a matter of invoking a method built into the Infragistics spell check control to show the dialog box. I was disappointed that I could quickly loop through all controls that had spell check enabled, in order to invoke this method. However, this was remedied rather quickly within the previously created function for adding and initializing other spell check features.
The last feature I really wanted to be part of this release was a shared dictionary. In order to share the dictionary amongst all users, I wanted the dictionary of words to be stored in the database. I did not see anything within the library where I could just point it to a table, or database, so back to the drawing board. I elected to add a few more functions to the now growing spell check helper utility. I added methods to complete the following, sync local text file dictionary to a new database word dictionary table, sync database to local text file, and then a method to perform 2 way synchronization. Calls to these methods are triggered when a user adds a word to the user dictionary, or by clicking an option manually within the context menu to synchronize with the dictionary.
Various reports attributed the attack to an email spam run gone wild, but security experts dismissed that theory, saying it had to be a coordinated attack from bots. "There's no way that simply spamming out email containing the links would generate that kind of traffic to the social networking sites. There simply wouldn't be enough people who would click on the links to create a DDoS," says Graham Cluley, senior technology consultant for Sophos. "So this must have been a 'traditional' DDoS attack from compromised computers [that] could hammer the Websites with multiple requests every few seconds."
