I have a web app that needs to parse through a file that is located on the
client machine. I get the file string from a query string & then parse it.
It is working fine on my development box but when I put it out on the test
server the application is looking for the file on the server & not on the
client machine.
I am essentially taking the query string & using a stream reader to read the
file.
I'm sure i'm doing something whacky...so PLEASE set me straight!

Browser security is going to prevent you from reading/writing
local files on the visitors PC. You are SOL unless you
write an ActiveX control, get the users to install it, and then
have them set their browser security settings to essentially
non-existant security.

Nothing to do with ASP.NET. You'd have to lower each of
their security settings in the browser to the lowest level possible.
Even then, the browser might not enable you to do this.
Why is it that you need to read/write a local file? Perhaps
you can achieve your goal another way.

Ya.... a local file on the clients machine. I can't install anything to the
clients machine & the HTML file input control won't work either because we
don't want the users to search for the file...which is why it's getting
passed in the query string.
Any ideas?

Microsoft has taken maybe hundreds of millions or more in this to make it
impossible to do what you want. You want an easy solution to do this.
Just my thought,

So is there no way to set the text for the File field? Even using Java
Script? Maybe hiding the file field & setting the text & then loading
that... I don't really care where I parse the file at...I could parse it
after I upload it...the main objective is to not allow the user to have to go
& select a file because the file is being passed by another application & our
users aren't very smart...we don't want them to try to find the file.
So how about some alternatives rather than Microsoft spending millions to
not allow programmers to do this.. which isn't very helpful.

Think about the consequences of what you are asking.
How do I either read or write to a local file via a browser?
How do I upload a file via browser without the user explicitly doing so?
The security implications are astounding. Hackers would have (and have had)
a field day.
This is precisely why MS spent so much money (and apparently need
to spend more because their stuff still isn't as secure as it needs to be).

You still haven't really explained why you need to read/write/upload
a file from their machine without them knowing?
What is in the file that you need a browser to have access to?
