Subject: Displaying text in a field
> I have a form that has some text fields in it. Each text field is set to
> 500 characters. The width of each field (on the form) is set at 102.
The
> rest of the data is displayed when a user taps on a "Note" icon (it pops
up
> a form that has a scrolling text field that can display the full 500

> characters are not in a "fixed" width. In other words, the "W" takes up
> more space that an "i" etc.
> My question is how can I tell when the 102 field width is exceeded?
