We often use a database backend such as 
SQL Server to store data. In such 
databases, you have to specify the length of any textual field when a table is 
designed. If you tried to insert a record whose text length is greater than 
allowed by your table, an error will be reported. 
To prevent this type 
of error from occurring, developers can use 
MaxHTMLLength in the Cute Editor to limit the length of the 
user’s input.
