    • InStrRev Function

    Returns the position of an occurrence of one string within another, from the end of string.

    InStrRev(string1, string2[, start[, compare]])

    Arguments

    string1

    Required. String expression being searched.

    string2

    Required. String expression being searched for.

    start

    Optional. Numeric expression that sets the starting position for each search. If omitted, -1 is used, which means that the search begins at the last character position. If start contains Null, an error occurs.

    compare

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

    Settings

    The compare argument can have the following values:

    ConstantValueDescription
    vbBinaryCompare0Perform a binary comparison.
    vbTextCompare1Perform a textual comparison.

    Return Values

    InStrRev returns the following values:

    IfInStr returns
    string1 is zero-length0
    string1 is NullNull
    string2 is zero-lengthstart
    string2 is NullNull
    string2 is not found0
    string2 is found within string1Position at which match is found
    start > Len(string2)0

    Remarks

    The following examples use the InStrRev function to search a string: 

    Dim SearchString, SearchChar, MyPos
SearchString ="XXpXXpXXPXXP"   ' String to search in.
SearchChar = "P"   ' Search for "P".
MyPos = InstrRev(SearchString, SearchChar, 10, 0)
    ' A binary comparison starting at position 10. Returns 9.
MyPos = InstrRev(SearchString, SearchChar, -1, 1)
    ' A textual comparison starting at the last position. Returns 12.
MyPos = InstrRev(SearchString, SearchChar, 8)
    ' Comparison is binary by default (last argument is omitted). Returns 0.

    Note   The syntax for the InStrRev function is not the same as the syntax for the InStr function.
