How can Process.Start() command be used in a Web Application??

[bwalke]

I was wondering if and how the Process.Start() command can be used in a
VB.NET Web Application. I want the client side to invoke an .exe
application by clicking a button and I want the .exe to run on the
server side. When the button is clicked the .exe does not run and the
process fails. I have used this Process.Start() command in a Windows
Application before successfully. I have read in groups that it is not
possible to use Process.Start() and also have heard that it is possible
in Web Applications. I also seen stuff about impersonating a user to
run the .exe, does this have to been done, any good quick ways to go
about this. Here is what I have tried so far in the web app with no
luck...

Dim myProcess As New Process()
myProcess.EnableRaisingEvents = False
myProcess.StartInfo.WorkingDir­ectory =
"C:\NETProjects\test\AppTest\b­in\"
myProcess.StartInfo.FileName =
"C:\NETProjects\test\AppTest\b­in\AppTest.exe"
myProcess.Start()

Also have tried this...

myProcess =
Process.Start("C:\NETProjects\­test\AppTest\bin\AppTest.exe")

Any Suggestions would be great!!

Thanks,
Brett

You have a couple of choices I can think of off hand:

1. Wrap the funcationality in a service that can accept calls from your web
app. This approach is inherently more secure, but requires more programming
to get it up and running.

2. Allow the ASP.NET user (ASP_NET, or NETWORK_SERVICE if Windows 2003) to
have access to the executable. This is a potential security hole if you have
not locked down the page that fires the EXE.

How can you go about assigning the Network_Service 'user' access to run
an .exe file. This user is not listed in the User Group. Also, is
there a way to assign Network_Service to the Directory Security in IIS
for the page that is going to trigger the .exe file.

Thanks

I want to run an executable file on a server which is located on this
server and I want to have it triggered by a user from an intranet web
page.

roughly
using(System.Diatnostics.Process myProcess = new
System.Diagnostics.process()
{
myProcess.StartInfo.FileName = @"cmd";
myProcess.StartInfo.UseShellExecute = false;
myProcess.StartInfo.RedirectStandardInput = true;
myProcess.StartInfo.RedirectStandardOutput = true;
myProcess.StartInfo.RedirectStandardError = true;
myProcess.Start();

StreamWriter sIn = myProcess.StandardInput;
sIn.AutoFlush = true;
StreamReader sOut = myProcess.StandardOutput;
sIn.Write(" executable followed by command line args");
sIn.Close();
myProcess.Close();
}
