Replaces some string by another.
Replace (Expression As String, Find As String, Replace As String [, Start = 1 [, Count = -1 [, Compare = True]]]) As String
Expression: Any string expression that you want to modify.
Find: Any string expression that shall be searched for.
Replace: Any string expression that shall replace the found search string.
Start: Optional numeric expression that indicates the character position where the search starts and also the start of the substring to be returned.
Count: Optional maximum number of times the replace shall be performed. When set to -1, all possible replacements are performed.
Compare: Optional boolean expression that defines the type of comparison. The value of this parameter can be True or False. The default value of True specifies a text comparison that is not case-sensitive. The value of False specifies a binary comparison that is case-sensitive. You can as well use 0 instead of False or 1 instead of True.
MsgBox Replace ("aBbcnnbnn", "b", "$", 1, 1, False) 'returns "aB$cnnbnn" REM meaning: "b" should be replaced, but REM * only when lowercase (compare=False), hence second occurrence of "b" REM * only first (respecting case) occurrence (count=1) MsgBox Replace ("ABCDEFGHI", "E", "*", 4) REM returns D*FGHI because the search starts at position 4, which is also the start of the returned string. MsgBox Replace("aBbcnnbnn", "b", "$£", compare:=False) 'returns "aB$£cnn$£nn" REM Replace all (count = -1) "b" with "$£" respecting casing (compare=False) starting from first letter (start=1)
