Method

Returns the first n bytes in a source string.

Syntax

Introduced 5.0
result=LeftB(source, count)
OR
result=stringVariable.LeftB(count)

Part	Type	Description
result	String	The first count bytes of source. The encoding of result is the same as the source.
source	String	The source string from which to get the bytes.
count	Integer	The number of bytes you wish to get from source. If count is greater than the number of bytes in source, all bytes are returned.
stringVariable	String	Any variable of type String.

Notes

The LeftB function returns bytes from the source string starting from the left side (as the name implies). The encoding of the result is the same as the encoding of the source string.

If you need to read characters rather than bytes, use the Left function.

Examples

This example uses the LeftB function to return the first 5 bytes from a string.

Dim s As String
s = LeftB("Hello World", 5) // returns "Hello"
s = "Hello World"
s = s.LeftB(5) // returns "Hello"
