INSTRREV(stringcheck, stringmatch [,start] [,compare])
Returns the position of a substring within a larger string, starting at the end (Long).
|stringcheck||The text string containing your substring (String).|
|stringmatch||The text string to look for (String).|
|start||(Optional) The number of the character to start looking from.|
|compare||(Optional) A vbCompareMethod constant specifying the type of string comparison to use (Integer):|
-1 = vbUseCompareOption (uses the "Option Compare" setting)
0 = vbBinaryCompare
1 = vbTextCompare
2 = vbDatabaseCompare (uses an Access database)
|* This function is similar to INSTR except it starts searching at the end of the string, rather than at the beginning.|
* This function makes it very easy to parse a folder/file path and return just the filename.
* Although this function searches from the right hand side of the string, it counts characters from the left (the same as Instr).
* If "stringcheck" = "" (zero length string), then 0 is returned.
* If "stringcheck" is Null, then Null is returned.
* If "stringmatch" = "" (zero length string) then "start" is returned.
* If "stringmatch" cannot be found in "stringcheck" then 0 is returned.
* If "stringmatch" is Null, then Null is returned.
* If "start" > Len("stringcheck"), then 0 is returned.
* If "start" if left blank, then -1 is used (meaning the last character).
* If "start" is Null, then an error occurs.
* If "compare" is left blank, then -1 is used. If there is no Option Compare statement provided then vbBinaryCompare (0) is used.
* If "compare" is null, then an error occurs.
* If "compare" is provided, then "start" must also be provided.
* You can use the INSTR function to start at the beginning.
* This function was added in Office 2000.
* The equivalent .NET function is Microsoft.VisualBasic.Strings.InStrRev
