The default CAS permission grant for the intranet zone includes permission
to read from, but not write to, its directory of origin. This means that
you will either need to grant additional permissions to your assembly on the
client machine(s) or find an alternate means of saving the file. One option
that would not involve altering client-side permissions would be to pass the
data to a web service on the same server for writing to the desired target
file.
On the other hand, if you're using (or can upgrade to) v. 2.0 of the .NET
Framework, ClickOnce might also be an option. It would allow users to grant
additional permissions to your application without requiring separate
permission elevation steps. If you're using v. 1.x, you'll need to deploy
the policy modifications under administrative privileges. See
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetsec/html/entsecpoladmin.asp
for some options, and talk to your network admin. There may already be
something in place for distributing CAS policy changes and, if not, your IT
folks should still be involved in selecting CAS policy modification
approaches

The purpose of the C# EXE is to hand over the .TXT file to a Visual Foxpro
Program, which is in the same directory as the C# .EXE on the server.
The Visual Foxpro Program is waiting for this TXT file and picks it up, as
soon as is generated.
This is just a Setup until the Visual Foxpro Program is also rewritten in
C#.
Thanks

Hi Nicole,
Thanks for your reply.
In my case the program makes a calculation and puts 2 numbers in a .TXT
file
in the same directory. I think this is just a simple IO function.
Are there ways in .NET 2.0 to handle this in C# code?
Thanks again

case,
does the user select the target file location via a file save dialog?
If
not, does it matter where the file is located, or is it only important
that
your application be able to locate the data?

Hi,
My Problem: I have a C# EXE which writes a TXT file with results. It
works
perfect on my local computer, but when I try to run it from our
network
server (Drive G:), I am getting a
System.Security.Permissions.SecurityPermission error.
I found a lot of hints on the internet, also the .NET Framework
Configuration Utility, but I was not successful at all.
Has somebody a very simple to understand solution, what I have to
do,
to
bring this EXE on the server to run?
Thanks in advance
