CountFields Function
Returns the number of values (fields) in the string passed that are separated by the separator string passed. If the source string is binary data or you require case-sensitivity, use CountFieldsB instead.
Syntax
result = CountFields( source, separator )
Parameters | ||
source |
The original string. |
|
separator |
The character or characters that separate the values in source. |
Notes
The CountFields function is useful for reading columns of data from a text file where the columns (fields) are delimited with a specific character or characters.
If the separator is not found within source, CountFields returns 1. If source is null, CountFields returns zero.
Examples
The example below returns 5.
Dim s as String
s="Dan*Smith*11/22/69*5125554323*Male"
count=CountFields(s, "*")
The following example returns three because it counts the null "field" after the (unnecessary) final field delimiter.
