If the cursor is in an UltraText box with the SpellChecker property set to a SpellChecker, and if the form\program is closed, a Null reference error will occur.
I see that someone else referenced the same problem by asking how they could stop the SpellChecker dialog from firing in the event the form\program was closed. The answer was to not use the SpellChecker property on an UltraText box...
While that is fine as a bug WORKAROUND, it is NOT the solution to the problem. This needs to be fixed, or else the SpellChecker property on an UltraText box (or anything else) is worthless.
Hello,
Please let me know if you require further assistance with this matter.
I followed the steps you suggested and was unable to reproduce the behavior you're describing.
I have attached the sample project I used to test this. Please test this project on your PC; whether or not it works correctly may help indicate the nature of this problem.
If the project does not work correctly, this indicates either a problem possibly specific to your environment, or a difference in the DLL versions we are using. My test was performed using version 11.120111.1003 in NetAdvantage for .NET 2011 Volume 1.
If the project does show the product feature working correctly, this indicates a possible problem in the code of your application. It will help if you can provide a small, isolated sample application that demonstrates the behavior you are seeing.
Or, if this sample project is not an accurate demonstration of what you're trying to do, please feel free to modify it and send it back, or send a small sample project of your own if you have one.
Please let me know if I can provide any further assistance.
