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.
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. |
