Get Nth Line Method

Short Name: Get Nth Line

Installed With: Base Package

Class: String Methods

Gets the characters that make up the Nth line in a string control and returns the offsets in the original string in bytes.

You can use this method to determine how the text in a string control is word-wrapped. The position indexes are byte indexes. These are usually equivalent to character indexes, except when using text that has characters that use multiple bytes, such as Asian character sets.

Example

Parameters

Name	Required	Description
index	No	A number that indicates the line of text in the string control. Line numbers begin at zero.
text	No	A substring of the original string indicated by index.
start	No	The byte position in the original string where the substring begins.
end	No	The byte position in the original string where the substring ends.
