TextAreaLen ( textarea[,units] )
Parameters
|
textarea - text area gadget units (optional) - what to count: 1: characters (default) 2: lines |
Description
|
Returns the length of a text area's text, in characters or lines. Requires Extended language mode. Character units count whole Unicode characters - an accented letter or an emoji is one character, not several bytes - with each line break counting as one character (a carriage return). Line units count display lines; note that an empty text area still reports one (empty) line, while its character count is 0. The classic uses: iterating lines with a For loop up to TextAreaLen(area,2)-1, or grabbing everything with TextAreaText using the default full range.
