Compressed DLL - 62 Kb

Introduction

One of the many things that I have found lacking when using web based forums, such as CodeProject, is the lack of spell checking facilities within IE. So that I can post messages on forums that do not contain spelling mistakes, I created this little tool that allows you to check the spelling of certain words using the Google Spelling API.

Installation

Extract the signed TxtSpell.dll from the ZIP file and install using regsvr32. Visit and register with the Google Spelling API site to get a key to use with the DLL. This key will be stored in the registry under HKEY_CURRENT_USER\Software\Many Monkeys Limited\SpellChecker\Google. The object will ask you for the key when it requires it, so keep it to hand.

Usage

Once installed, the Spell Checker is easy to use. Select a word or words (up to 10) in the form that you wish to check the spelling of and select the Spell Check option from the context menu.

If Google decides that the words are incorrect then a new set of words will be returned and will be used to replace the currently selected text.

If there is an error, that maybe attributed to an incorrect or missing key (not 100%). Then the following install screen will popup. This install window can be used to install a new key and check if it works.

References

Limitations

Sometimes the install screen appears when the error is not due to an incorrect key but a problem with the Google service. However these are very rare.
The number of words that can be checked in one go is 10. This limit is imposed by the Google web service.
If all the words are correct or appear to be, then Google returns no answer and this is currently interpreted to be an error.

Future work

It is intended to use a different spell checking mechanism that will allow the user to select from a collection of words when a mis-spelt word is found. It is also intended to provide source code once I have integrated another spell checking mechanism such that there would be more than a few lines of non-wizard code.

I hope you find this tool useful. Please feel free to comment and offer suggestions.

All articles are supplied as-is, as a howto on a particular task that worked for me in the past. None of the articles are supposed to be out-of-the-box freeware controls and nor should they be treated as such. Caveat emptor.

Been involved in programming from the early '80s. First on my Spectrum, then an Amstrad. Did lots of Fortran while at University before becoming involved in Forth, Prolog, Pascal, Occam, C and eventually C++. Eventually started programming on the Windows platform using Borland’s OWL framework, during my postgraduate years. When I started work in '94, I learnt MFC followed by COM and ATL and never looked back. Now working exclusively in .NET, working on WinForms, ASP.NET and the Compact Framework using C# and VB.NET. Using every bit of the .NET framework I can such as WebServices and writing my own controls for my .NET Portal, and for the Compact Framework. Still lots I don't know, but the end of the universe hasn't happened yet - I wonder if I'll have time?

I was a permanent employee for a number of companies until Dec 2000 before going independent after the DotCom I ws involved with went DotBomb. Now supplying consulting services to various institutions in London and surrounding regions i.e. UK Smile

Now started using BizTalk and the latest .NET framework - yeha.

The Google API, no idea as how to use it . I have registered the DLL using regsvr32. Can anyone give me a clue as how go about it. Want to use it in ASP in a textarea field. Mahboob Software Engg

Problem with Spell Check -- Request Not Going To Google Web API

Deepak Kumar Vasudevan

4:03 16 Dec '02

Hi, Does this component has any restrictions/limitations that I should not be behind any proxy server/NAT firewalls? Since I am behind a NAT firewall, it never goes to Google but hits my NAT firewall and request goes to NAT server's Apache Web Server and gets a 404 entry into the log.

It shouldn't have any problems I use this module at work and it works fine behind the NAT firewall there.

The module uses SOAP to communicate with the google service and that may have been blocked by the administrator.

Technically speaking the dictionary would define Visual Basic users as programmers.
But here again, a very generalized, liberal definition is being employed and it's wrong

I honestly couldn't tell you - missing DLL perhaps? its only supposed to rely on system DLLs so i'd be surprised if it was that.

I tried 'regsvr32 d:\downloads\txtspell.dll' and all was well

does your path have a break in it?

try regsvr32 "d:\downloads\txtspell.dll" instead ie using quotes

I did get worried thinking it might be the digital signature as it has just been renewed but no that seems okay

Hi, This tool didn't work for me. Damn I might have missed some steps... I registerd the DLL and got the license key from Google. Now where should I enter this Google License Key? Kant. (I can)

Now worked for me.. Earlier I registered the DLL with "COM Explorer", it didn't work. This time I registered with the "regsvr32", it worked. Thanks Kant

Source code?

The article looks cool, but where's the source?

He states:

I think he should have waited till the source was ready, or that the article was better documented as a how to:

Hi - I didn't provide the source as there was nothing really new in it.

I posted the link on how to register a Menu Extension.

I posted a link to the Google APIs - which I found as a comment to one of the other spell checking articles on this site.

There is nothing clever in using the res: protocol - The google bar does that.

The ATL wizards did most of the work - eg I added the .wsdl file and a header file was created automatically for it. The only complicated things was thinking of what names to use for the dll, class and method.

I added method called SpellCheck and then I typed 3 lines of code that did the work.
The rest of the code is just Key support and registry access - it took less than 4 hours to write and I was watching a double episode of 'Stargate' and some dodgy home video program while supping a beer, and waiting for Google to respond with my copy of the Key. (maybe the beer supping is why I haven't posted the code Smile

). I signed the DLL as an experiment to make sure I could remember how to still do it.

I posted the tool as that is what it is - a tool. I am going to be fairly busy the next few weeks and I didn't want to forget - as I have on lots of little bits and pieces that are on my TODO list.

Maybe I should have created a HowTo instead and I may do that but I thought people may want to use the tool now rather then wait until I get time to write a more complete article.

Re: Source code? Colin^Davies 22:41 11 Sep '02

Hi,
I was just interested in how you did it.
Your response was almost a how to anyway.
I'm actually using a product that someone offered for beta testing via the toolbar.

My other box has some IE stuff I registered toolbars etc that I mad for testing and now have forgotten how to remove.

maybe this article will help Internet Explorer Toolbar (Deskband) Tutorial[^] it's got a section on the registry - I looked at this and at Browser Helper Objects before deciding that Menu Extensions was the easiest way to go.
