I have a VB .net 2.0 site that needs to run a dos app upon a button
click.
I found Shell too unreliable using parameters and so used
system.diagnost ic.process.
simple troubleshooting example that opens up Notepad.....
Imports System.Diagnost ics
Dim myProcess As New Process
Dim ShellCmd As String
ShellCmd = "notepad.ex e"
myProcess.Start Info.FileName = ShellCmd
myProcess.Start ()
The code works fine - but only in debug mode - ie calling the browser
from the IDE (VS Web Dev express).
When I just use a browser - any browser, I get: an error .
Access is denied
at System.Diagnost ics.Process.Sta rtWithShellExec uteEx(ProcessSt artInfo
startInfo)
When i set this up identically on my home machine it fails silently -
but still works from the IDE
Any ideas why this simple code would fail from a browser but run in
the IDE in debug mode?
Thanks

Hi Bill,
I suspect that "Access is denied" means that the regular (non-debug) ASP.NET
account doesn't have sufficient permissions to execute that command.
When you're debugging in the IDE, I'd bet that you have privileges well
beyond those of mortal men. <grin>
I'm curious about one thing... if you do get Notepad to run outside the
environment, who is going to type the text and click Save? <grin>

I did set permissions on the real command that I was trying to shell
( properties , security) - I added "Everyone" with full control and it
made no difference.
Is there another way to set permissions that I missed?

Hi Bill,
You'll want to use impersonation in the web.config file. You need to
impersonate a Windows account that has the same rights as you do and that
can interact with the desktop.
<system.web>
<identity impersonate="tr ue" userName="Windo wsDomain\YourUs erName"
password="YourP assword" />
</system.web>

Impersonation did not help.
Could this be some basic .Net or IIS security setting wrong on my part?
I have seen lots of seemingly easy to use examples of using Process.start on
the web so I don't understand why it should be so hard for me to start
notepad!

ok but then it will better simulate my reall app I am trying to shell.
Trust me - I would would not waste so much energy trying to run Notepad :-)
If "Shell" can do it easily why can't Process.start?
Should I move this thread to the security group?
