Dim psi As ProcessStartInfo = New ProcessStartInfo("cmd.exe")
        psi.RedirectStandardOutput = True
        psi.RedirectStandardInput = True
        psi.UseShellExecute = False
        psi.CreateNoWindow = True
 
        Dim p As Process = Process.Start(psi)
        p.StandardInput.WriteLine("ren c:\a.txt b.txt")
        p.StandardInput.WriteLine("exit")

ProcessStartInfo psi = new ProcessStartInfo("cmd.exe");
        psi.RedirectStandardOutput = True;
        psi.RedirectStandardInput = True;
        psi.UseShellExecute = False;
        psi.CreateNoWindow = True;

        Process p = Process.Start(psi);
        p.StandardInput.WriteLine("ren c:\a.txt b.txt");
        p.StandardInput.WriteLine("exit");

well, that's great for vb and php developers... but what about c#?

[mendhak]

That is for C#. In PHP tags. For color formatting. Forgive my transgression.

[dekelc]

do I need to add a "using" reference for ProcessStartInfo?

because it doesn't reognise it...

[mendhak]

Use System.Diagnostics

thanks mendhak!!!!

Good. Now add [Resolved]

Bear in mind that if its just a single command you can tag it onto the end of the call to start "cmd.exe" .

[dekelc]

hey penagate! how do I do that in code?

I mean, use the start command??

[jmcilhinney]

Process.Start(appPath, argString);

e.g.

Process.Start("cmd", @"ren c:\a.txt b.txt");

Hello. Im trying to do the same thing but with a telnet window.
Telnet will not allow you to redirect the standard IO

Can you please tell me how I can send commands to the telnet without using sendkeys.send()?

Maybe you could look at my thread

well mendhak, it doesn't work after all...
I just tried it for the first time and it faild...

maybe I need to add an "Enter" key after each line?

thanks

A 'writeline' includes an 'enter'. It sends the whole command.
What failed, what did you get instead?

[dekelc]

ok... It's working! thanks!

but is there a way to know if my commands succeeded?
