Short Name: Get Nth Line
Requires: Base Development System
Class: String Methods
To Use: Create a method.
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.
| Data type | Name | Required | Description |
|---|---|---|---|
| line index | Yes | A number that indicates the line of text in the string control. Line numbers begin at zero. |
| line text | Yes | A substring of the original string indicated by index. |
| position of line start | Yes | The byte position in the original string where the substring begins. |
| position of line end | Yes | The byte position in the original string where the substring ends. |
The following table lists the characteristics of this method.
