my mistake that I haven't expressed myself correctly. I fully agree with you, that you are able to change the length in this particular field in xml file, or even change the length of the section name field in the database. This field is defined in the database as varchar with 256 bytes of length.
I agree with you that at the time, that someone will put more characters, the message "Error writing to database" will appear.
But let me come back to the point and to my question. I asked whether it is possible to specify the number of characters, so that it will be possible to put somewhere more user-friendly message, instead of the above notice about error with writing to database.
I want to avoid such situation, of getting bunch of emails from users who will be not able to find out, what went wrong.
Is there any chance to control the number of characters and display more user-friendly message, at the time when the number of characters will exceed the given limit?
