I want to run in C# the command:
PRINT /D:\\rshprt04\p-RSH108 C:\Users\o-tsoudry\Files\Tehila.txt
I tried the next code:
string result = proc.StandardOutput.ReadToEnd();
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
string exception;
try
{
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
string fileName = #"C:\Users\o-tsoudry\Files\Tehila.txt";
string printer_Name = #"\p-RSH108 ";
startInfo.Arguments = "PRINT /D:\\rshprt04" + printer_Name + fileName;
process.StartInfo = startInfo;
process.Start();
}
catch (Exception ex)
{
exception = ex.Message;
}
But it's not working.
When I stand on the process in debugging I see the error:
ExitCode = 'proc.ExitCode' threw an exception of type 'System.InvalidOperationException'
Any idea?
Try Below :
ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = fileName;
psi.Arguments = "\"" + PrinterName + "\"";
psi.Verb = "PrintTo";
Process.Start(psi).WaitForExit();

I want to do the same code for multiple lines so I created a text file in resources and that's my code
string[] commands = File.ReadAllLines(SodaScript.Properties.Resources.ServicesToDisable);
foreach (string command in commands)
{
Process process = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = "sc.exe";
startInfo.Arguments = "config " + command + " start= disabled";
startInfo.Verb = "runas";
process.StartInfo = startInfo;
process.Start();
}
and this is the txt file
but it gives this error
You can use just a regular string array:
string[] commands = {
"DiagTrack",
"DusnSvc",
"etc"
};
foreach (string command in commands)
{
Process process = new Process();
...
}
I am not sure but i think i have problems with some permissions...
I have this method:
static void ExecuteCommand(string _Command)
{
System.Diagnostics.ProcessStartInfo procStartInfo = new System.Diagnostics.ProcessStartInfo("cmd", "/c " + _Command);
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
procStartInfo.CreateNoWindow = false;
//procStartInfo.WindowStyle = ProcessWindowStyle.Hidden;
procStartInfo.Verb = "runas";
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo = procStartInfo;
proc.Start();
string result = proc.StandardOutput.ReadToEnd();
proc.WaitForExit();
MessageBox.Show(result);
}
First, i was executing this code in a desktop app and it works.
string createDB = #"sqlcmd -S " + SQLINSTANCE + #" -Q ""CREATE DATABASE " + DBNAME + #"""";
ExecuteCommand(createDB);
But now im trying to execute it in the setup-project with custom action getting this error:
CREATE DATABASE permission denied in database 'master'.
If i execute this string in a cmd console (with and without admin privileges) it work perfectly...
Where is the problem?
Try with the properties UserName and Password instead of runas.
var psi = new ProcessStartInfo();
psi.Domain = "domain";
psi.UserName = "username";
psi.Password = password;
i have been looking up "how to get standard output from cmd" and i found a few tutorials, but none, yes NONE seemed to work, im trying to read all the output that "cmd.exe" has for me.
heres the whole code, Scroll down for the error location
public static string C(string arguments, bool b)
{
System.Diagnostics.Process process = new
System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new
System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle =
System.Diagnostics.ProcessWindowStyle.Hidden;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardInput = true;
process.StartInfo.UseShellExecute = false;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = arguments;
process.StartInfo = startInfo;
process.Start();
string res = "";
if (b)
{
StringBuilder q = new StringBuilder();
while (!process.HasExited)
{
q.Append(process.StandardOutput.ReadToEnd());
}
string r = q.ToString();
res = r;
}
if(res == "" || res == null)
{
return "NO-RESULT";
}
return res;
}
Where i get my error (System.InvalidOperationException: 'StandardOut has not been redirected or the process hasn't started yet.')
string res = "";
StringBuilder q = new StringBuilder();
while (!process.HasExited)
{
q.Append(process.StandardOutput.ReadToEnd()); // Right here
}
string r = q.ToString();
res = r;
You are creating a ProcessStartInfo named startInfo, then set some properties on process.StartInfo and then assign startInfo to process.StartInfo basically reverting what you set previously.
You should be setting RedirectStandardOutput, RedirectStandardInput and UseShellExecute on the startInfo:
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.RedirectStandardOutput = true;
startInfo.RedirectStandardInput = true;
startInfo.UseShellExecute = false;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = arguments;
process.StartInfo = startInfo;
process.Start();
I dont know where is my missing. Even it dit not write out log. Could you fix my test code:
private void button1_Click(object sender, EventArgs e)
{
try
{
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = #"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe";
startInfo.Arguments = #"/C Import-Module AppLocker;Set-AppLockerPolicy -XMLPolicy 'iPolicy.xml' > C:\log.txt";
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;
//startInfo.RedirectStandardOutput = true;
//startInfo.RedirectStandardError = true;
//startInfo.UseShellExecute = false;
//startInfo.CreateNoWindow = false;
Process process = new Process();
process.StartInfo = startInfo;
process.Start();
process.WaitForExit();
}
catch (Exception ex) {
Debug.Print("Error: " + ex.Message);
}
}
Finally got it to work, code should look like this:
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = #"cmd.exe";
startInfo.Arguments = #"/C powershell.exe /C Import-Module AppLocker;Set-AppLockerPolicy -XMLPolicy 'iPolicy.xml' > C:\log.txt";
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;
Process process = new Process();
process.StartInfo = startInfo;
process.Start();
process.WaitForExit();
This worked for me! You can use full paths to cmd.exe and powershell.exe if you feel necessary, it's not that important here.
After looking on forums, I have written this snippet:
public string ExecuteCmd()
{
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = this.m_command;
process.StartInfo = startInfo;
process.Start();
string output = process.StandardOutput.ReadToEnd();
process.WaitForExit();
return output;
}
The m_command is member of a class, initialized in the constructor.
For my tests, it is net user. When the compiler arrives at this point, I get the following exception:
StandardOut has not been redirected or the process hasn't started yet.
Where is my mistake?
You need this:
//....
startInfo.Arguments = "/C " + this.m_command;
process.StartInfo = startInfo;
process.StartInfo.RedirectStandardOutput = true;
process.Start();
//....
