Permissions on Network shares

[Jake Holt]

I'm a converted Java programmer so go easy on me..

Basically I wrote a program for my Sales department that parses EDI 852s and
returns a csv file for them. My problem is when i move it to the share I
have to trust the assembly in the .net configuration first, not a problem
really as there won't be many people using it, but my next project is company
wide and I really don't want to walk around and trust the assembly on every
machine. I've been hacking away at this permission thing for a good bit of
time now and seem to be missing something. can anyone answer these questions
for me please?

1. Say I have StreamWriter sw = new StreamWriter(outputPath.text + "\\" +
outputFN.text). How would i write a permission to give my users access to
read/write to this file dynamically? the fileIOAccess example in the MSDN
isn't very clear and doesn't seem to work for me. Always returns the typical
permission failure (Request for permissions.fileio mscorb.... failed).

2. is there an easy way to automatically trust your assembly over the entire
intranet at once so users can run it without running the .net config on their
local machine? I tried the .net config on the dev server but that didn't
seem to make a difference.

3. is there a good book/article anyone knows about thats in depth and
explains when/why/how these permissions are applied.

thanks in advance
