shell,console and standard input and output

[Christophe HELFER]

Hi,

I would like to do this in VB Languague.

I have an executable file in DOS mode. This executable returns informations
and display them to the DOS window. Unfortunately, I have to process theses
informations.
The way to do that, is to redirect standard input and output, insn't it ?
This is possible in C++ language, but I cannot make any line in this
language.

Then I have tried with the Console class but this class don't execute
programs like the Shell() function ! The line I tried is :
console.write(" Exename") and with the Console.read () method, I obtain no
data !

Can anyone tell me if I did wrong, or if it's simply possible !

thanks for your help

Hi Chrisophe,

Why not write it to disk and than read it back, more simple I cannot
imaging?

Just my thought.

Because this program is interactive like ftp in DOS mode, you have to put
commands and then you get the response. This is unfeasible with external
file.

I can :-)

take a look at
System.Diagnost ics.Process

look at the StandardOutput property
in the class reference you have an example how to get the process output
very easy

Thanks for your help, but perhaps I'm stupid.
I've tried with the ftp.exe as executable, so I can have interaction.
By trying this piece of code in a Console application, the variable strOut
is empty !

Sub Main()
Const Path = "C:\WINNT\Syste m32\ftp.exe"

Const Args = "hostname"

Dim P As New Process

Dim strOut As String

P.StartInfo.Use ShellExecute = False

P.StartInfo.Red irectStandardOu tput = True

P.Start(Path, Args)

strOut = P.StandardOutpu t.ReadToEnd()

Debug.Write(str Out)

P.WaitForExit()

P.Close()

End Sub
