redirecting STDIN/STDOUT

[Christophe Helfer]

hi,

I have some problem with redirecting input and output from a process.
Situation:
I have to use the Cisco Network Registrar (DNS And DHCP server) command
line utility as redirecting its input and output so I can interact with this
one. This utility is similar to ftp under a win32 console. It proposes its
own prompt after launching it.

What I want to do is:

- input some command (normally I have to write into the input stream)
- then get the response from the output stream.

This operations sequence must be repeated more than one time

I create a process with the right parameter such as useshell=false and
redirect in,out,err =true and app name =cmd.exe
(when I use directly app=<utility> it does not work)

when I write the command into the InputStream, I go a correct response into
the response stream but incomplete. In fact, there is one or more streams
behind the first one. You can get these streams if you pass in addition to
the peek function.
Then, after gathering the last stream the application freeze !

I already seek for code to achieve my goal but all code I've found doesn't
work for my situation
Code tested : VB.Net, VB and API, C/C++
How can I solve my problem, can anyone help me!

After many and many hours searching, I despair
Thanks a lot!

Hi Christophe

I absolut do not know how to solve your problem, however when you said the
same as ftp I had to think on this website, maybe it is there.

Hi Christopher,

I thought I had used this sample however it is not true, can you try this
one I made a short while ago (based on an MSDN sample), this is a sample for
the standardoutput I showed someone some days ago, so you have to make the
standardinput something the same.

Maybe this helps?

Dim p As New Process
p.StartInfo.Use ShellExecute = False
p.StartInfo.Red irectStandardOu tput = True
p.StartInfo.Arg uments = "C:\Test1 C:\TestA\"
p.StartInfo.Wor kingDirectory = "C:\windows\sys tem32"
p.StartInfo.Fil eName = "xcopy"
p.Start()
Dim sr As IO.StreamReader = p.StandardOutpu t
Dim sb As New System.Text.Str ingBuilder("")
Dim input As Integer = sr.Read
Do Until input = -1
sb.Append(ChrW( input))
input = sr.Read
Loop
Dim sw As New IO.StreamWriter ("C:\Test2\myte st.txt")
sw.Write(sb.ToS tring)
sw.Close()
