There have been discussions on this list about different circumstances where
JAWS ini functions are unreliable. I recently scoped out one particular
circumstance where these functions fail entirely, or actually write to the
wrong file. The problem occurs when the following 2 conditions are met.
1. The ini functions are called 2 or more times consecutively but on
different files. And 2. The different files have the exact same name, but
they are in different folders. Here are the details along with some
examples:
If you write to an existing INI file in an existing folder path, and then
try writing to a same-named INI file in a different folder path, there will
be a failure to write to that second same-named INI file. Instead, what
happens is that the first written INI file is written to. For instance:
1. Write to the file <Anatomy.ini> in the path <C:\Girls\Anatomy.ini>. THIS
WORKS JUST FINE.
2. Next try writing to the same-named file <Anatomy.ini> that's in the path:
<C:\Boys\Anatomy.ini>. THIS CONSISTENTLY FAILS. What happens is that instead
of the Boys' INI file being written to, the Girls' INI file is written to.
The exact same failure occurs if the folders don't exist and you're using
IniWriteString () to both create them and write to the INI file. For
instance:
1. Create and write to <C:\Girls\Anatomy.ini.>. THIS CREATES AND WRITES JUST
FINE.
2. Next try to create and write to <C:\Boys\Anatomy.ini.>. THIS CONSISTENTLY
FAILS TO CREATE THE NEW FOLDER PATH.
Instead, what happens is that the Anatomy.ini in the Girls folder is written
to.
Finally, if you're merely wanting to create folders, the same behaviour
holds. If the last folder in the second path is the same name as the last
folder in the first path, then you can't create the second group of folders.
For instance
1. Create and write to <C:\Parents\Students>. THIS CREATES THE FOLDERS JUST
FINE.
2. Next try to create <C:\Teachers\Students>. THIS CONSISTENTLY FAILS TO
CREATE THE NEW FOLDER PATH.
Note that this behaviour is not corrected by including the IniFlush ()
function, but it temporarily goes away by reloading JAWS.
On a different but related note. Sometimes when trying to manually delete
one of those newly JAWS' created folders, Windows says "You need permission
to perform this action" But if you shut down JAWS, deletion is successful. I
haven't rigourously tested this out yet, so I can not duplicate the failure
every time.
