Hi All.

I'm looking for a little function: Pass a string, return a string.
A VB6 app wants to write a file, The users chosen path is 'C:\FileName.ext'.
The app 'appears' to do this but actually writes to file to a completely
different path, something like
'C:\Users\UserName\AppData\Local\VirtualStore'
This is UAC Virtualization. AKA Data Redirection
I would like a function where I can pass the users chosen location and it
will return the the actual path that the file will be written to.
Any pointers please

Thanks

Ivar

There is no such function.
That path is not made public, or exposed to any app and is subject to
change.

If you want to get the full path, add the vista manifest to your EXE so
it correctly gets a permissions error rather than the write being faked
to elsewhere.

I'm curious what the value is in knowing the
path. For a normal user on Vista/7 it's no longer
a PC, really. It's a service appliance. *One does
not have the right to access the filesystem*.
Looking at it the other way, if you're going to
run with normal user rights, why would you need
to access the filesystem? The presumption is that
you have some kind of software that a person uses
to create, save and edit personal files. Since you have
the rights of the person using the software, you also
have to take the approach that you're using a service
rather than an OS.

I don't mean to criticize your question. Just
exploring, interested to know how different people
deal with these things.
I wonder if you could set up a file system activity
monitor, but then that would probably require admin
rights.

Take these two examples to explain my question
Using MS Word 2002 on Windows 7
I open word, type some text and save file to C Drive, all appears OK, except
the file is not there in explorer
I open Notepad, type some text and try to save to C Drive, Notepad informs
me that I do not have permission to save to this location.
So what I would like to do is something like Notepad, Test if the user has
permission to write a file to the selected location and if not then suggest
an alternative, rather than how word 2002 and my prog does it.

Thanks

Ivar

As I said, use the manifest.
Notepad has it, Word 2002 doesn't.
The redirection is ONLY for older "incompatible" applications that
expect to be able to write to these locations.
