RightPartR function String / Filename routines

Unit

acUtils

Declaration

function RightPartR(const SubStr, Str: String): String;

Description

The RightPartR function finds the LAST occurence of any sub-string (SubStr parameter) in specified string (Str parameter), and returns the part of string (SubStr) AFTER the separator (Str). If the SubStr can not be found in the Str, the function returns empty string. Unlike RightPart function, the RightPartR starts searching the sub-string from the right side of string.

If you would like to find FIRST occurence of sub-string in specified string — use RightPart function.

Example

SubKey := RightPartR('\', 'Software\Microsoft\CurrentVersion');

// the result will be 'CurrentVersion'

Original code

function RightPartR(const SubStr, Str: String): String;

var

I: Integer;

begin

I := PosR(SubStr, Str);

if I <> 0 then

Result := Copy(Str, I + Length(SubStr), Length(Str))

else

Result := '';

end;
