Limit number of character

I have an access database linked up to my ASP page.

All is working fine, but I want to limit the number of characters that one of my field can display.


Title : Kirupa is the greatest site ever.

I want to limit this field to 20 charaters and display like this

Title : Kirupa is the greatest…

I’m not sure how do it, I’m not even sure what this function is called.

Any help on how do do it or what it is called would be great.
