Syntax
Replace(expression,
find, replacewith[, start[, count[, compare]]])
The Replace function syntax has these parts:
| Part | Description |
| 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. |
| count | Optional. Number of substring substitutions to perform. If omitted, the default value is -1, which means make all possible substitutions. |

The compare argument can have the following values:
| Constant | Value | Description |
| vbBinaryCompare | 0 | Perform a binary comparison. |
| vbTextCompare | 1 | Perform a textual comparison. |
| vbDatabaseCompare | 2 | Perform a comparison based on information contained in the database where the comparison is to be performed. |
Return 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 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
' A binary comparison starting at the beginning of the string.
MyString = Replace("XXpXXPXXp", "p", "Y")
' Returns "XXYXXPXXY".' A textual comparison starting at position 3.
MyString = Replace("XXpXXPXXp", "p", "Y", 3, -1, 1)
' Returns "YXXYXXY".
