I'm migrating batch script to .Net core and I'm trying to open another terminal from current terminal and run a command (I don't need stderr o stout).
With batch only needs this command: start cmd /K gulp. I'm trying to do the same with .Net core but only found the way to run the command inside current terminal.
private static string Run (){
var result = "";
try
{
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = "cmd.exe";
startInfo.Arguments = $"/c \"gulp browserSync\"";
startInfo.RedirectStandardOutput = true;
startInfo.RedirectStandardError = true;
startInfo.UseShellExecute = false;
startInfo.CreateNoWindow = true;
using (Process process = Process.Start(startInfo))
{
result = process.StandardError.ReadToEnd();
process.WaitForExit();
}
}
catch (Exception Ex)
{
Console.WriteLine(Ex.Message);
Console.ReadKey();
}
return result;
}
I'm trying changing this properties in order to open in another terminal:
startInfo.RedirectStandardOutput = false;
startInfo.RedirectStandardError = false;
startInfo.UseShellExecute = true;
But make an exception:
UseShellExecute must always be set to false.
From the MSDN docs:
UseShellExecute must be false if the UserName property is not null or an empty string, or an InvalidOperationException will be thrown when the Process.Start(ProcessStartInfo) method is called.
startInfo.UserName = null;
edit: I'm not sure why you have to pass in the arguments, but if all you want is a new CMD window try this:
try
{
ProcessStartInfo startInfo = new ProcessStartInfo
{
FileName = "cmd.exe",
WorkingDirectory = #"C:/users/replace/where_gulp_is_located",
Arguments = #"/c gulp", // add /K if its required, I don't know if its for gulp for to open a new cmd window
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardError = true
};
Process proc = new Process();
proc.StartInfo = startInfo;
proc.Start();
if (showOut)
{ ///code }
}catch(Exception ex)
{
Console.WriteLine(ex);
}
You wont need startInfo.UserName in this case because you are specifying a working directory.
Thanks to #bender-bending answer I found a way to solve it. Due security limitations need user/password credentials in order to autorice current terminal to open a new one.
WorkingDirectory, user, password and domain are required.
Create no window, redirect output and redirect error must be false, in order to see command result in new window.
public static void Sample(){
try
{
Console.Write("Password: ");
StringBuilder password = new StringBuilder();
while (true)
{
var key = System.Console.ReadKey(true);
if (key.Key == ConsoleKey.Enter) break;
password.Append(key.KeyChar);
}
ProcessStartInfo startInfo = new ProcessStartInfo
{
FileName = "cmd.exe",
WorkingDirectory = "C:/path_to/Gulp",
Arguments = $"/c \"gulp browserSync\"",
UseShellExecute = false,
RedirectStandardOutput = false,
RedirectStandardError = false,
UserName = Machine.User(),
PasswordInClearText = password.ToString(),
Domain = Machine.Domain(),
CreateNoWindow = false
};
Process proc = new Process();
proc.StartInfo = startInfo;
proc.Start();
//proc.WaitForExit();
} catch (Exception ex)
{
System.Console.WriteLine(ex);
System.Console.ReadKey();
}
}
.Net Core doesn't have a method to obtain user and domain. We can use this class to get this values from environment variables.
public static class Machine
{
public static string User(){
return Environment.GetEnvironmentVariable("USERNAME") ?? Environment.GetEnvironmentVariable("USER");
}
public static string Domain(){
return Environment.GetEnvironmentVariable("USERDOMAIN") ?? Environment.GetEnvironmentVariable("HOSTNAME");
}
}
Hope it helps!

I am working on a C# .net core project.I created a process to run "xdotool windowactivate $windowpid".I should store the windowID which process run on it.The solution could be any property of xdotool which i couldn't find,or Is there any way to take windowId of a process when it is created?
Another Try is that:
I created my pages with this method. I tried to take mainwindowtitle of process;because of single process,i couldn't take the titles.
static List<string> chromeTitles = new List<string>();
public static Process StartChrome(string filePath)
{
string dataDirectory = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Chrome-UserData");
filePath += " --user-data-dir=" + dataDirectory;
var Chrome = new Process
{
StartInfo =
{
FileName = "C:/Program/chrome.exe",
Arguments = filePath,
UseShellExecute = false,
CreateNoWindow=true,
WindowStyle = ProcessWindowStyle.Maximized,
}
};
Chrome.Start();
string title = Chrome.MainWindowTitle;
chromeTitles.Add(title);
}
Then I call it :
StartChrome("https://tr.wikipedia.org/wiki/Anasayfa");
Thread.Sleep(2000);
StartChrome("https://tureng.com/");
You can use the Process class for accessing more capabilities.
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.FileName = "xdotool.exe";
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
startInfo.Arguments = $"windowactivate $windowpid";
process.StartInfo = startInfo;
process.Start();
To get the PID of the process that got run by the code, you can use Process.ID property:
process.Id;
if you want to read the output, you can add this code:
string output = process.StandardOutput.ReadToEnd();
To get Output, startInfo.RedirectStandardOutput should be True.
I need to call headless chrome from a net core console application. But with this code the aplication run and get stuck doing nothing and printing nothin, also the pdf is not created. The same arguments in the terminal are working as expected.
public static bool TakeScreenshot2()
{
try
{
var procStartInfo = new ProcessStartInfo()
{
FileName = "google-chrome",
Arguments = "--headless --disable-gpu --print-to-pdf=final.pdf http://www.google.com/",
RedirectStandardOutput = true,
RedirectStandardError = true,
UseShellExecute = false,
CreateNoWindow = true
};
var proc = new Process { StartInfo = procStartInfo };
proc.Start();
var output = proc.StandardOutput.ReadToEnd();
Console.WriteLine(output);
string error = proc.StandardError.ReadToEnd();
Console.WriteLine(error);
return proc.ExitCode == decimal.Zero ? true : false;
}
finally
{
// do something
}
}
You should wait for the process to finish
var proc = new Process { StartInfo = procStartInfo };
proc.Start();
proc.WaitForExit();
You can check if it was success also with proc.ExitCode after it exit
If you dont want to block the thread unit it finish you can run it with, you function needs to be async
await Task.Run(() => proc.WaitForExit());
or to use the Process event Exited
I am trying to create an application which will install the msi from the c# windows application, here i wanna take the input from user for UserName, Domain and password so that i can run the application in that user account. in the below code if i only give startInfo.Verb = "runas" its working but i want to provide the user name and password of admin and run it. can you guyz help me out.
private void InstallProbe()
{
try
{
bool gdfg= IsRunAsAdmin();
//processObj.InitializeProcess(txtUserName.Text, txtPassword.Text);
string installcmd = "/c msiexec /i \"{0}\" /quiet TARGETDIR=\"{1}\" HOST=\"{2}\" PORT=\"{3}\" USEHTTPS=\"{4}\" STEALTHMODE=\"{5}\" ORGCODE=\"{6}\"";
installcmd = string.Format(installcmd, txtFilePath.Text, #"%PROGRAMFILES%\ProHance Mate", "services.jamochatech.com", "8080", false, 0, "PHSALE");
string uname, domain = string.Empty;
//RunCommand("cmd", installcmd, processObj);
if (txtUserName.Text.IndexOf("\\") > 0)
{
string[] strarr = txtUserName.Text.Split('\\');
uname = strarr[1];
domain = strarr[0];
}
else
{
uname = txtUserName.Text;
domain = ".";
}
Process process = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();
//startInfo.Verb = "runas";
startInfo.Domain = domain;
startInfo.UserName = uname;
startInfo.Password = ToSecureString(txtPassword.Text);
startInfo.FileName = "cmd";
startInfo.Arguments = installcmd;
startInfo.CreateNoWindow = true;
startInfo.UseShellExecute = false;
startInfo.LoadUserProfile = true;
MessageBox.Show(installcmd);
process.StartInfo = startInfo;
process.Start();
process.WaitForExit(60000);
}
catch (Exception ex)
{
MessageBox.Show("Exception occured while installing the ProHance Mate " + ex.Message);
}
}
Disregarding the MSI context, you are simply trying to launch a new process (msiexec.exe) under a specific user context. Check the thread below and others alike.
In Windows: How do you programatically launch a process in administrator mode under another user context?
I want my application not to need an Admin to use it.
I should be usable for a normal user.
When a user wants to change some settings of the app I need Admin Rights.
So I want to launch a second instance of the application which requires Admin Rights.
(with user agreement request and so on)
Is there any way to accomplish that?
I tried:
Process p = new Process();
p.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
p.StartInfo.FileName = Application.ExecutablePath;
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
if (System.Environment.OSVersion.Version.Major >= 6)
{
p.StartInfo.Verb = "runas";
}
p.Start();
But it seems not to work.
You can to create an account with admin rights,
Then populate the user,password properties on the ProcessStartInfo instance with the corresponding values for the admin account.
Something like:
var psi = new ProcessStartInfo
{
FileName = "notepad.exe",
UserName = "admin",
Domain = "",
Password = pass,
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardError = true
};
Process.Start(psi);
Turns out i have to use the UseShellExecute in the ProcessStartInfo and not the Process.
More explanation here.
ProcessStartInfo proc = new ProcessStartInfo();
proc.UseShellExecute = true;
proc.WorkingDirectory = Environment.CurrentDirectory;
proc.FileName = Application.ExecutablePath;
proc.Verb = "runas";
try
{
Process.Start(proc);
}
catch
{
return; //U have a BIG problem!
}
I have following code
using (StreamWriter outfile = new StreamWriter(#"f:\trial.cpp"))
{
outfile.Write(txtCode.InnerText);
}
System.Diagnostics.ProcessStartInfo procStartInfo = new System.Diagnostics.ProcessStartInfo(#"cl.exe", #" 'trial.cpp'");
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
procStartInfo.UserName = "asdasd";
SecureString secureString = new SecureString();
foreach (char c in "abcded")
{
secureString.AppendChar(c);
}
procStartInfo.Password = secureString;
// Do not create the black window.
procStartInfo.CreateNoWindow = true;
procStartInfo.WorkingDirectory = #"f:\";
// Now we create a process, assign its ProcessStartInfo and start it
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo = procStartInfo;
proc.Start();
// Get the output into a string
string result = proc.StandardOutput.ReadToEnd();
How to pass file name as parameter? Above code doesn't run and I have tried all full path, different path options.
can anyone help?
The argument is set incorrectly. You have:
var procStartInfo = new ProcessStartInfo(#"cl.exe", #" 'trial.cpp'");
Where there are spaces and single quotes in the name. Try:
var procStartInfo = new ProcessStartInfo(#"cl.exe", #"trial.cpp");
EDIT:
startInfo.CreateNoWindow = false;
startInfo.UseShellExecute = false;
startInfo.FileName = "CL.exe";
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.Arguments = "trial.cpp";
try
{
using (Process exeProcess = Process.Start(startInfo))
{
exeProcess.WaitForExit();
}
}
catch
{
// error handling
}
The point here is that CL is a command line executable, not a windows GUI application.

If the cl.exe is not in the system PATH (which by default it is not) then the start process will not find the executable and it will fail to run.
So I suspect you are seeing the fact that the cl.exe is not in the system PATH.
