LeftPartR function
String / Filename routines |
acUtils
|
function LeftPartR(const SubStr, Str: String): String;
|
The LeftPartR function finds the LAST occurence of any sub-string (SubStr parameter) in specified string (Str parameter), and returns the part of string (SubStr) BEFORE the separator (Str). If the SubStr can not be found in the Str, the function returns empty string. Unlike LeftPart function, the LeftPartR 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 LeftPart function.
|
ParentRegKey := RightPartR('\', 'Software\Microsoft\CurrentVersion');
|
// the result will be 'Software\Microsoft'
|
function LeftPartR(const SubStr, Str: String): String;
|
var
|
I: Integer;
|
begin
|
I := PosR(SubStr, Str);
|
if I <> 0 then
|
Result := Copy(Str, 1, I - 1)
|
else
|
Result := '';
|
end;
