Replace Function
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]]])
Arguments
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.
Settings
The compare argument can have the following values:
| Constant | Value | Description | | vbBinaryCompare | 0 | Perform a binary comparison. | | vbTextCompare | 1 | Perform a textual comparison. |
Return Values
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 occurences of find removed. | | start > Len(expression) | Zero-length string. | | count is 0 | Copy of expression. |
Remarks
The return value of the Replace function is a string, with
substitutions made, that begins at the position specified by start and
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:
Dim MyString
MyString = Replace("XXpXXPXXp", "p", "Y") ' A binary comparison starting at the beginning of the string. Returns "XXYXXPXXY".
MyString = Replace("XXpXXPXXp", "p", "Y", ' A textual comparison starting at position 3. Returns "YXXYXXY". 3, -1, 1)
