I have used the Spell and Thesaurus controls for quite some time. But when running my applications on Vista, the CheckWord() method of the Thesaurus returns this error if the Thesaurus has suggestion:
<br>
<br>
System.ArgumentException was unhandled
Message="The output char buffer is too small to contain the decoded characters, encoding 'Unicode (UTF-8)' fallback 'System.Text.DecoderReplacementFallback'.

The same application running on Windows 2000 or Windows XP works fine. My version of the control is 1.2.20053.60. But I downloaded the evaluation version of the most current version (2.2.20071.73) and the behavior is the same.

<br>
If anyone has a workaround or if ComponentOne is able to fix the control, please let me know. Thanks,

Hi,

Please try the latest build of C1Spell for .Net which is available for
download at below mentioned link:

For.Net 1.x

http://prerelease.componentone.com/dotnet/c1spell/2007-t3/c1spell_1.2.20073.75.zip

For .Net 2.0

http://prerelease.componentone.com/dotnet20/c1spell/2007-t3/c1spell.2_2.2.20073.78.zip

If the issue still persists then please provide me with a small sample
exhibiting the said behavior.

I hope this helps.

Have a nice day ahead.

Regards,
John Adams
