Method

Returns the number of values (fields) in the string passed that are separated by the separator string passed.

Usage

result = CountFieldsB(source, separator)

Part Type Description
result Integer The number of values in source that are separated by separator.
source String The original string.
separator String The character or characters that separates the values in source. Separator can be of any length.

Notes

CountFieldsB is identical to CountFields, except that it treats the source string as a series of raw bytes. Use this instead of CountFields if you need the function to be case-sensitive.

The CountFieldsB 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, CountFieldsB returns 1. If source is null, CountFieldsB returns zero.

Sample Code

The code below returns 5.

Dim count As Integer
Dim s As String
s = "Dan*Smith*11/22/69*5125554323*Male"
count = CountFieldsB(s, "*")

The following code returns three because it counts the null "field" after the (unnecessary) final field delimiter.

Dim count As Integer
Dim s As String
s = "Dan*Smith*"
count = CountFieldsB(s, "*")

See also the code that illustrates how to populate a PopupMenu control.
