.bat from asp.net w/System.Diagnost ics.Process?

I need to be able to execute a .bat file from a C# web application
I have the following code that compliles and seems to run fine, but the bat file never does it's work
=============== =============== =====
System.Diagnost ics.Process p = new Process()
p.StartInfo.Red irectStandardOu tput=false
p.StartInfo.Fil eName = "C:\\ftp_script s\\script.bat"
p.StartInfo.Use ShellExecute=tr ue
p.Start()
p.WaitForExit()
p.Dispose();
=============== =============== ======
The bat file works fine when i don't call it from the web app

What could be wrong?
Is it a permissions thing?
Why am I not getting any errors?
How do I get errors back to my calling code

Any help would be greatly appreciated

how do you know the bat file is not working? Are you testing the results of
what the bat file executed to know this? You cannot run the application and
look for a bat file window. If you insist that the bat file is not firing
off, here is another way to invoke it using the command line modifying your
code.

System.Diagnost ics.Process p = new Process();
// p.StartInfo.Red irectStandardOu tput=false;
p.StartInfo.Red irectStandardOu tput=true;
p.StartInfo.Red irectStandardIn put=true;

p.StartInfo.Fil eName = @"cmd"; //"C:\\ftp_script s\\script.bat";
// p.StartInfo.Use ShellExecute=tr ue;
p.StartInfo.Use ShellExecute=fa lse;

p.Start();
// p.WaitForExit() ;
// p.Dispose();

StreamWriter sIn = myProcess.Stand ardInput;
sIn.AutoFlush = true;
StreamReader sOut = myProcess.Stand ardOutput;

sIn.Write(@"C:\ ftp_scripts\scr ipt.bat" + System.Environm ent.NewLine);
sIn.Close();

string results = sOut.ReadToEnd( ).Trim();
p.Close();

The results of the script, whether it failed to run or errored out will be
contained in results variable so you can know exactly what is going on.

Thanks for your help Alvin, but I still can't get the sript to run. I tried to simplify the code by executing the command that was in the bat file directly from this script, still no luck.

The cmd simply takes a file and ftp's it to another server. the output is recorded in a log file. If I execute the cmd from the cmd line, it works fine (the file is moved, and there is an entry in the log file)

When I execute it with the following script from an .aspx, no file moved and no log entry.

I'm stumped!! Any other idea's why this might not be working

=============== =============== ========
System.Diagnost ics.Process p = new Process()
p.StartInfo.Red irectStandardOu tput=true
p.StartInfo.Red irectStandardIn put=true
p.StartInfo.Fil eName = @"cmd"
p.StartInfo.Use ShellExecute=fa lse
p.Start()
StreamWriter sIn = p.StandardInput
sIn.AutoFlush = true
StreamReader sOut = p.StandardOutpu t

sIn.Write(@"ftp -s:c:\ftp_script s\ftp.txt >> c:\ftp_scripts\ ftp_log.txt" + System.Environm ent.NewLine)
sIn.Close()

string results = sOut.ReadToEnd( ).Trim()
p.Close()

Response.Write( results)

what is the results of the script from the command prompt when you run using
a webpage?
i'm not familiar with the syntax of the ftp command you are using. from the
docs, ftp takes a verb followed by command line options. Post your script
code if you still have problems.

Great, so here is where you start. After each line in your script, echo it
to the screen. Then run the app. Just follow the screen output to find which
line is failing.

uname
pword
cd mydir

quit
=============== ====

I'd really like to figure out why my code won't run from a web page, but I
really just need to be able to ftp from an .aspx page. If you know of a
better way, I'm open to anything that works.

Thanks for your help.

ok, I think I've found a problem, but I'm not sure why it's happening

If I use the command prompt, from "C:\Windows\sys tem32", if i type in ftp and hit enter the next line I get is "ftp>", I can then enter open 11.22.33.44 and it promts me for my uname.... and I'm on my way

When I execute the following code from the .aspx, the output shows
"Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp. C:\WINDOWS\syst em32>ftp C:\WINDOWS\syst em32>".

Where I would have expected
"Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp. C:\WINDOWS\syst em32>ftp ftp>"

System.Diagnost ics.Process p = new Process()

(NOTE that the commands after ftp are commented out

Why from the .aspx page is it going back to
C:\WINDOWS\syst em32
and not to
ftp
??

you may have to put a "ftp" followed by a newline command so that it is
sitting in the ftp prompt before you start firing your command line params.
That should fix it.
