running cmd in c# answer yes to prompt

I'm running the below command from c#. There is a prompt that will be shown that I want to answer "yes" to how can I do this with the current code
If I run this as a batch script I can just do
echo y | pscp.exe -batch -pw password E:\\Certs\\client.conf me#<ip>:/home/user
which works - but unsure how I can replicate this using the below
string pscpPath="-batch -pw password E:\\Certs\\client.conf me#<ip>:/home/user";
ExecuteCopyCerts("pscp.exe", pscpPath);
Function:
public Boolean ExecuteCopyCerts(string fileName, string arguments)
{
txtLiveHubStatus.Text = "";
try
{
System.Diagnostics.ProcessStartInfo procStartInfo = new System.Diagnostics.ProcessStartInfo(fileName, arguments);
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
procStartInfo.CreateNoWindow = true;
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo = procStartInfo;
proc.Start();
string result = proc.StandardOutput.ReadToEnd();
return proc.ExitCode == 0;
}
}

Set RedirectStandardInput to true
procStartInfo.RedirectStandardInput = true
and then write to StandardInput
proc.StandardInput.WriteLine("yes");

To reiterate what Hesam said though the prompt is Y, not yes. This is the prompt for the cert, which only occurs on the first call to each new linux machine. I use this code today in one of our applications.
ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = "pscp";
psi.RedirectStandardInput = true;
psi.RedirectStandardOutput = false;
psi.Arguments = $"-r -p -pw {passWord} \"{localFileNamePath}\" {userName}#{hostName}:{remotePath}";
psi.UseShellExecute = false;
psi.CreateNoWindow = true;
using (Process process = new Process())
{
process.StartInfo = psi;
process.Start();
process.StandardInput.WriteLine("Y");
process.WaitForExit();
}

Run WinSat Command C#

I am trying to run cmd winsat -drive c programmatically
The code below is only returning "Windows System Assessment Tool" the first line of the output but is not letting the winsat run and return the rest of the output
I am looking for the entire output to be returned shown here
The code I am using is this
public string RunAndOutput(object command)
{
var procStartInfo =
new ProcessStartInfo("winsat", "/c " + "-drive c");
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
procStartInfo.CreateNoWindow = true;
var proc = new Process();
proc.StartInfo = procStartInfo;
proc.Start();
string result = proc.StandardOutput.ReadToEnd();
proc.WaitForExit(); // Wait for everything to finish
return result;
}

You will need to wait for the process to exit using WaitForExit(), like this:
public string RunAndOutput(object command)
{
var procStartInfo =
new ProcessStartInfo("cmd", "/c " + command);
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
procStartInfo.CreateNoWindow = true;
var proc = new Process();
proc.StartInfo = procStartInfo;
proc.Start();
string result = proc.StandardOutput.ReadToEnd();
proc.WaitForExit(); // Wait for everything to finish
return result;
}

How to hide the Command Window using c#

Building a console app that will execute an exe file(pagesnap.exe). I would like to hide its window(pagesnap.exe) during execution. How is it done.
ProcessStartInfo Psi = new ProcessStartInfo("D:\\PsTools\\");
Psi.FileName = "D:\\PsTools\\psexec.exe";
Psi.Arguments = #"/C \\DESK123 D:\files\pagesnap.exe";
Psi.UseShellExecute = false;
Psi.RedirectStandardOutput = true;
Psi.RedirectStandardInput = true;
Psi.WindowStyle = ProcessWindowStyle.Hidden;
Psi.CreateNoWindow = true;
Process.Start(Psi).WaitForExit();
DESK123 is the local PC. Would later try this with remote PCs.
Things I have tried
Psi.Arguments = #"/C start /b psexec \\DESK123 D:\files\pagesnap.exe";
Psi.Arguments = #"/b psexec \\DESK123 D:\files\pagesnap.exe";
Psi.Arguments = #"/C psexec \\DESK123 /b D:\files\pagesnap.exe";
Psi.Arguments = #"/C psexec \\DESK123 D:\files\pagesnap.exe 2>&1 output.log";
Update: I have built pagesnap with Output type as a windows application instead of console. The cmd window doesn't come up, now. Seems this is the only way for me

Simply call the following function. Pass the argument as your command and your working directory
private string BatchCommand(string cmd, string mapD)
{
System.Diagnostics.ProcessStartInfo procStartInfo = new System.Diagnostics.ProcessStartInfo("cmd", "/c " + cmd);
procStartInfo.WorkingDirectory = mapD;
// The following commands are needed to redirect the standard output.
// This means that it will be redirected to the Process.StandardOutput StreamReader.
procStartInfo.RedirectStandardOutput = true;
procStartInfo.RedirectStandardError = true;
procStartInfo.RedirectStandardInput = true;
procStartInfo.UseShellExecute = false;
// Do not create the black window.
procStartInfo.CreateNoWindow = true;
// Now we create a process, assign its ProcessStartInfo and start it
System.Diagnostics.Process cmdProcess = new System.Diagnostics.Process();
cmdProcess.StartInfo = procStartInfo;
cmdProcess.ErrorDataReceived += cmd_Error;
cmdProcess.OutputDataReceived += cmd_DataReceived;
cmdProcess.EnableRaisingEvents = true;
cmdProcess.Start();
cmdProcess.BeginOutputReadLine();
cmdProcess.BeginErrorReadLine();
cmdProcess.StandardInput.WriteLine("ping www.google.com"); //Execute ping
cmdProcess.StandardInput.WriteLine("exit"); //Execute exit.
cmdProcess.WaitForExit();
// Get the output into a string
return Batchresults;
}
static void cmd_DataReceived(object sender, DataReceivedEventArgs e)
{
if (e.Data != null)
Batchresults += Environment.NewLine + e.Data.ToString();
}
void cmd_Error(object sender, DataReceivedEventArgs e)
{
if (e.Data != null)
{
Batchresults += Environment.NewLine + e.Data.ToString();
}
}

How do I get the output from my VBScript Console using C#?

My application opens a website then runs a VBS file to do some data input. Once it's completed the data input, I want to quit the application.
In my current iteration, the VBS file executes and my C# code keeps going (quitting the web app before the data entry is completed).
Process.Start(appPath + #"external\website.url");
getAllProcesses(false);
ProcessStartInfo startInfo = new ProcessStartInfo(appPath + #"\external\UNLOCK.vbs", employeeID);
Process scriptProc = new Process();
scriptProc.StartInfo.FileName = #"cscript";
scriptProc.StartInfo.WorkingDirectory = appPath + #"external\";
scriptProc.StartInfo.Arguments = "UNLOCK.vbs " + employeeID;
scriptProc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; //prevent console window from popping up
scriptProc.StartInfo.RedirectStandardError = true;
scriptProc.StartInfo.RedirectStandardInput = true;
scriptProc.StartInfo.RedirectStandardOutput = true;
scriptProc.StartInfo.ErrorDialog = false;
scriptProc.StartInfo.UseShellExecute = false;
scriptProc.Start();
scriptProc.WaitForExit(); // <-- Optional if you want program running until your script exit
Read(scriptProc.StandardOutput);
Read(scriptProc.StandardError);
while(true)
{
String completed = Console.ReadLine();
scriptProc.StandardInput.WriteLine(completed);
if(completed.CompareTo("Completed") == 0)
{
break;
}
}
if (scriptProc.HasExited)
{
getAllProcesses(true);
Application.Exit();
}
scriptProc.Close();
I want to only execute
getAllProcesses(true);
Application.Exit();
ONLY After I get output from my VBS file that says "Completed".
My VBS file has a line that says
WScript.Echo "Completed"
at the end.

Process scriptProc = new Process();
ProcessStartInfo info = new ProcessStartInfo();
info.WorkingDirectory = appPath + #"external\";
info.FileName = "Cscript.exe";
info.Arguments = "UNLOCK.vbs" + employeeID;
info.RedirectStandardError = true;
info.RedirectStandardInput = true;
info.RedirectStandardOutput = true;
info.UseShellExecute = false;
info.WindowStyle = ProcessWindowStyle.Hidden;
scriptProc.StartInfo = info;
scriptProc.Start();
scriptProc.WaitForExit();
bool exit = false;
while (!scriptProc.StandardOutput.EndOfStream)
{
if (scriptProc.StandardOutput.ReadLine() == "Completed")
{
exit = true;
break;
}
}
if (exit == true)
{
getAllProcesses(true);
Application.Exit();
}

Reading output from another running application

I'm working on a custom IDE in C# for a scripting language, and I have a problem.
I'm trying to start the compiler process (pawncc.exe) and pass arguments to it. I've done that, and now I have a problem. When I want to display the output from the compiler application, it only displays some parts of it. It should output this (got this from the command prompt):
Pawn compiler 3.2.3664 Copyright (c) 1997-2006, ITB CompuPhase
newGM.pwn(0) : fatal error 100: cannot read from file: "includes/main_include.inc"
Compilation aborted.
1 Error.
But it doesn't. It outputs this (in the application, using the same command/arguments):
Pawn compiler 3.2.3664 Copyright (c) 1997-2006, ITB CompuPhase
1 Error.
I just don't get it! It's a really weird thing. It might be something simple but I've been looking at it, and researching for hours now! Here's my code:
public Form3(string path)
{
InitializeComponent();
this._path = path;
Process myProcess = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo("pawncc.exe");
startInfo.CreateNoWindow = true;
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
startInfo.Arguments = path + " -r -d2";
myProcess.StartInfo = startInfo;
myProcess.Start();
while (true)
{
string myString;
byte[] buffer = new byte[512];
var ar = myProcess.StandardOutput.BaseStream.BeginRead(buffer, 0, 512, null, null);
ar.AsyncWaitHandle.WaitOne();
var bytesRead = myProcess.StandardOutput.BaseStream.EndRead(ar);
if (bytesRead > 0)
{
myString = Encoding.ASCII.GetString(buffer, 0, bytesRead);
}
else
{
myProcess.WaitForExit();
break;
}
richTextBox1.Text = myString;
}
}
!!EDIT:
It does the same thing with this code:
public Form3(string path)
{
InitializeComponent();
this._path = path;
Process myProcess = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo("pawncc.exe");
startInfo.CreateNoWindow = true;
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
startInfo.RedirectStandardError = true;
startInfo.Arguments = path + " -r -d2";
myProcess.StartInfo = startInfo;
myProcess.Start();
using (StreamReader reader = myProcess.StandardOutput)
{
string result = reader.ReadToEnd();
richTextBox1.Text = result;
}
}

You need to redirect the standard error stream as well:
startInfo.RedirectStandardError = true;
Edit: I just reviewed the code and discovered that you are only readonly the StandardOutput stream.
I generally monitor the process for both the standard and error output streams using the DataReceived events on the process and adding the results into a stringbuilder, then storing the StringBuilder content in the UI element:
private static System.Text.StringBuilder m_sbText;
public Form3(string path)
{
InitializeComponent();
this._path = path;
Process myProcess = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo("pawncc.exe");
startInfo.CreateNoWindow = true;
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
startInfo.RedirectStandardError = true;
startInfo.Arguments = path + " -r -d2";
myProcess.StartInfo = startInfo;
m_sbText = new System.Text.StringBuilder(1000);
myProcess.OutputDataReceived += ProcessDataHandler;
myProcess.ErrorDataReceived += ProcessDataHandler;
myProcess.Start();
myProcess.BeginOutputReadLine();
myProcess.BeginErrorReadLine();
while (!myProcess.HasExited)
{
System.Threading.Thread.Sleep(500);
System.Windows.Forms.Application.DoEvents();
}
RichTextBox1.Text = m_sbText.ToString();
}
private static void ProcessDataHandler(object sendingProcess, DataReceivedEventArgs outLine)
{
// Collect the net view command output.
if (!String.IsNullOrEmpty(outLine.Data))
{
// Add the text to the collected output.
m_sbText.AppendLine(outLine.Data);
}
}
There are obviously variations on this, but this should get you started.

I dont have the pawnCC application so I cant try but it appears they restrict the verbosity of debugging information to external applications - apart from the command prompt.
Can you try spawning the pawncc.exe via cmd:
"cmd.exe \c CommandParameterToLaunchPawnCCwithArguments"

I've noticed some sporadic issues when dealing with the raw output/error streams from spawned processes in the past, hence why I usually deal with captured output via eventing:
Process myProcess = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo("pawncc.exe");
startInfo.CreateNoWindow = true;
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
startInfo.RedirectStandardError = true;
startInfo.Arguments = path + " -r -d2";
myProcess.EnableRaisingEvents = true;
myProcess.OutputDataReceived += OnOutputDataReceived;
myProcess.ErrorDataReceived += OnErrorDataReceived;
myProcess.StartInfo = startInfo;
myProcess.Start();
myProcess.BeginOutputReadLine();
myProcess.BeginErrorReadLine();
