Replace Function

Updated: August 2009

Returns a string in which a specified substring has been replaced with another substring a specified number of times.


                      Replace(expression, find, replacewith[, start[, count[, compare]]])
expression

Required. String expression containing substring to replace.

find

Required. Substring being searched for.

replacewith

Required. Replacement substring.

start

Optional. Position within expression where substring search is to begin. If omitted, 1 is assumed. Must be used in conjunction with count.

count

Optional. Number of substring substitutions to perform. If omitted, the default value is -1, which means make all possible substitutions. Must be used in conjunction with start.

compare

Optional. Numeric value indicating the kind of comparison to use when evaluating substrings. See Settings section for values. If omitted, the default value is 0, which means perform a binary comparison.

The compare argument can have the following values:

Constant

Value

Description

vbBinaryCompare

0

Perform a binary comparison.

vbTextCompare

1

Perform a textual comparison.

Replace returns the following values:

If

Replace returns

expression is zero-length

Zero-length string ("").

expression is Null

An error.

find is zero-length

Copy of expression.

replacewith is zero-length

Copy of expression with all occurrences of find removed.

start > Len(expression)

Zero-length string.

count is 0

Copy of expression.

The return value of the Replace function is a string, with substitutions made, that begins at the position specified by start and concludes at the end of the expression string. It is not a copy of the original string from start to finish.

The following example uses the Replace function to return a string:

' This is a binary comparison (because the last argument is omitted),
' so the comparison is case-sensitive.
' Returns ABC123def
Result = Replace ("ABC123abc", "abc", "def")

' This is a text comparison, so the comparison is case-insensitive.
' Returns def123def
Result = Replace ("ABC123abc", "abc", "def", 1, -1, vbTextCompare)
