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.diagnostic.process.
simple troubleshooting example that opens up Notepad.....
Imports System.Diagnostics
Dim myProcess As New Process
Dim ShellCmd As String
ShellCmd = "notepad.exe"
myProcess.StartInfo.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.Diagnostics.Process.StartWithShellExecuteEx (ProcessStartInfo
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="true" userName="WindowsDomain\YourUserName"
password="YourPassword" />
</system.web>
Here's an article on doing the same programmatically: http://west-wind.com/weblog/posts/1572.aspx

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!

Notepad is going to be rough to start because it presents a graphical
interface in a non-graphical environment.

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?
