String Length with Len() and LenB()
Len() returns the number of characters in a string. Spaces are characters too, even when consecutive spaces are collapsed visually by normal HTML rendering.
Count characters
Dim my_string
my_string="Welcome to Plus2net.com"
Response.Write my_string
Response.Write "<br>Length of this string = " & Len(my_string)Output
Welcome to Plus2net.com
Length of this string = 23Leading spaces count
my_string=" Welcome to Plus2net.com"
Response.Write my_string
Response.Write "<br>Length of this string = " & Len(my_string)Output
Welcome to Plus2net.com
Length of this string = 26The browser collapses consecutive spaces in normal HTML, but Len() still counts the three leading spaces.
LenB() and byte-oriented length
my_string="Welcome to Plus2net.com"
Response.Write my_string
Response.Write "<br>Length of this string = " & Len(my_string)
Response.Write "<br>Byte-oriented length = " & LenB(my_string)Legacy example output
Welcome to Plus2net.com
Length of this string = 23
Byte-oriented length = 46LenB note:
LenB() is byte-oriented and may differ from Len() for Unicode/DBCS data. Do not treat a fixed 2-bytes-per-character result as a portable rule for storage, network payload size, or UTF-8 length.ASP Home
