Run executable in a silent mode

I am executing .exe file in C# using the code below.
If I want to run executable in a silent mode I usually uncomment UseShellExecute and RedirectStandardOutput properties, but this gives me an error:
Unhandled Exception: System.ComponentModel.Win32Exception: The system cannot find the file specified
If I keep a code like this it runs, but the additional command line screen is popping up and closing.
I am running Poisson Surface Reconstruction .exe and wondering if the silent mode is possible or not? Or it must be implemented by author who did this executable?
var proc = new System.Diagnostics.Process {
StartInfo = new System.Diagnostics.ProcessStartInfo {
FileName = "PoissonRecon",
Arguments = "--in " + fileNameIn + " --out " + fileName + " --depth "+depth.ToString()+" --pointWeight 0 --colors",
//UseShellExecute = false,
//RedirectStandardOutput = true,
CreateNoWindow = true,
WorkingDirectory = filePath
}
};
proc.Start();
proc.WaitForExit();

Try adding to arguments line this:
"--mode unattended"
if I'm not mistaken it should make installation silent

Getting execption whenever it runs from process.start

so im having this weird issue with a win 7 pc. I have this application that runs this powershell script from a .bat file.
This is the code:
public void GetLastestEarthBackground()
{
var directoryPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Scripts");
var vbsFile = Path.Combine(directoryPath, Settings.VBSFileName);
if (File.Exists(vbsFile))
{
var process = new Process
{
StartInfo =
{
WorkingDirectory = directoryPath,
Verb = "runas",
UseShellExecute = true,
FileName = "run.bat", //Settings.VBSFileName,
Arguments = "//B //Nologo"
}
};
process.Start();
process.WaitForExit();
}
}
When i run it from my application i see this in the command line:
But if i double click on the batch file i get this resut:
Any ideas?

This seems like a issue with user rights, the program running the script probably does not have the same rights as your user.

Executing batch file located on remote machine

I'm trying to execute a batch file that is located on a remote machine with the following line of code:
System.Diagnostics.Process.Start(\\10.0.24.103\somePath\batchFile.bat);
And it blocks on this line of code. When I try to run it manually (by writing that address in Windows Explorer), it works, but I have to accept a security warning message first. I'm assuming this is why it's blocking when it's done through code...is there any way to force it to execute through code?

I solved my problem by adding more detail to the ProcessStartInfo object:
var process = new Process();
var startInfo = new ProcessStartInfo
{
CreateNoWindow = true,
FileName = "cmd.exe",
Arguments = "/c \"\"" + batchFile + "\"\"",
WorkingDirectory = AppDomain.CurrentDomain.BaseDirectory,
UseShellExecute = false,
RedirectStandardError = true,
RedirectStandardOutput = true
};
process.StartInfo = startInfo;
process.Start();
process.WaitForExit(30000);
I needed to specify to use cmd.exe, as well as surrounding the batchFile path in double quotes in case there are spaces in the path.

Try prefacing it with cmd /c(that's a space after /c).
Is this IP address a Windows machine on your domain etc.

Command Line Process

So after scouring the web I found a few articles (some on stackoverflow) which described how to execute a command line prompt by starting a new process in c#. The second argument, which I've commented out, works just fine, but the one I actually need (the first one) doesn't. It returns the error "Could not find or load main class edu.stanford.nlp.parser.lexparser.LexicalizedParser" When I open up a command line (non-programatically) and then execute the same command (aside from the escaped quotations) it works great. Any idea's about what the problem could be? Thanks!
var proc = new Process
{
StartInfo = new ProcessStartInfo
{
FileName = "CMD.exe",
Arguments = "/c java -mx100m -cp \"*\" edu.stanford.nlp.parser.lexparser.LexicalizedParser edu/stanford/nlp/models/lexparser/englishPCFG.ser.gz libtest.txt",
// Arguments = "/c echo Foo",
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardError = true,
CreateNoWindow = true
}
};
proc.Start();
Console.WriteLine(proc.StandardOutput.ReadToEnd());
Console.WriteLine(proc.StandardError.ReadToEnd());

Ensure that the executing path where you start your process is correct!
You can use Process Monitor from SysInternals to figure out where that class is looked for.

How to run shell script with C# on OSX?

I'd like to use C# to execute a shell script.
Based on similar questions I came to a solution that looks like this.
System.Diagnostics.Process.Start("/Applications/Utilities/Terminal.app","sunflow/sunflow.sh");
It currently opens Terminal, then opens the shell file with the default application (Xcode in my case). Changing the default application is not an option, since this app will need to be installed for other users.
Ideally the solution will allow for arguments for the shell file.

I can't test with a Mac right now, but the following code works on Linux and should work on a Mac because Mono hews pretty closely to Microsoft's core .NET interfaces:
ProcessStartInfo startInfo = new ProcessStartInfo()
{
FileName = "foo/bar.sh",
Arguments = "arg1 arg2 arg3",
};
Process proc = new Process()
{
StartInfo = startInfo,
};
proc.Start();
A few notes about my environment:
I created a test directory specifically to double-check this code.
I created a file bar.sh in subdirectory foo, with the following code:
#!/bin/sh
for arg in $*
do
echo $arg
done
I wrapped a Main method around the C# code above in Test.cs, and compiled with dmcs Test.cs, and executed with mono Test.exe.
The final output is "arg1 arg2 arg3", with the three tokens separated by newlines

Thanks Adam, it is good starting point for me. However, for some reason when I tried with above code (changed to my needs) I am getting below error
System.ComponentModel.Win32Exception: Exec format error
see below code that gives above error
ProcessStartInfo startInfo = new ProcessStartInfo()
{
FileName = "/Users/devpc/mytest.sh",
Arguments = string.Format("{0} {1} {2} {3} {4}", "testarg1", "testarg2", "testarg3", "testarg3", "testarg4"),
UseShellExecute = false,
RedirectStandardOutput = true,
CreateNoWindow = true
};
Process proc = new Process()
{
StartInfo = startInfo,
};
proc.Start();
while (!proc.StandardOutput.EndOfStream)
{
string result = proc.StandardOutput.ReadLine();
//do something here
}
and spent some time and come up with below and it is working in my case - just in case if anyone encounter this error try below
Working Solution:
var command = "sh";
var scriptFile = "/Users/devpc/mytest.sh";//Path to shell script file
var arguments = string.Format("{0} {1} {2} {3} {4}", "testarg1", "testarg2", "testarg3", "testarg3", "testarg4");
var processInfo = new ProcessStartInfo()
{
FileName = command,
Arguments = arguments,
UseShellExecute = false,
RedirectStandardOutput = true,
CreateNoWindow = true
};
Process process = Process.Start(processInfo); // Start that process.
while (!process.StandardOutput.EndOfStream)
{
string result = process.StandardOutput.ReadLine();
// do something here
}
process.WaitForExit();
