Access to client HDD from Web Application?

[Toma]

Hello !
First, excuse me for my very bad English, but I'll try to explain my problem
.....
I write my first Web Application on C# and ASP.NET /till now I write only
for Windows/, and this WebApp must read and write files on the client
computer.
Can someone explain how the browser can do this ?

P.S. -> WebApp is for our company and all reading and writing data will be
with agreement of our clients.......
I wish you best !

Toma -

there is no way to do this. If you "need" to access data on client's hard
drive, you'll need to write a client application (Windows forms or a console
app) that must be ran with "FullTrust" or "Everything" permission set on the
client.

Cheers,
Branimir

Toma,

Along the same lines as what Branimir said, you could make a *windows forms
control* that runs with full trust in IE (similiar to a java applet) to
handle your file writing but this is basically a WinForm app deployed under
no-touch with regard to client permissions. However, if you need to present
it as web page, maybe this is closer to what you are looking for?
