Reading String from last character downwards

sabzam · 2009-02-25

Hi to everyone,

How can I read a string from the last character backwards and stopping for example when a '\' is found? What I am doing is trying to get the file name from a whole path

Can anyone help pls?

Regards

Not exactly what you asked for, but i used this for separating filename and directory from a given path.

WHILE STRPOS(filename,'\') <> 0 DO
  BEGIN
    path +=  COPYSTR(filename,1,STRPOS(filename,'\'));
    filename := DELSTR(filename,1,STRPOS(filename,'\'));
  END;

Or:

FOR i := STRLEN("MyString") DOWNTO 1 DO BEGIN
  MESSAGE('%1',COPYSTR("MyString",i,1));
END;

Thanks for your answer,

The function as it is gets the path a removes the file name
But what if I needed the file name instead of the path?

check this thread: viewtopic.php?f=23&t=29284&hilit=SplitDirFile

the SplitDirFile function does what you need, i believe.

In my example the variable path holds the path and the variable filename the filename.
Really..
