C#: Windows Console Application to Windows Service

I have a console application that tracks the performance of the computer, and I am trying to make it into a Windows Service. The service installs fine, however when I go into task manager and try to run the service I get Error 1053: the service did not respond to the start or control request in a timely fashion. In the task manager the service sometimes has a "starting" status, but it will not run.
On top of that, when I run the console app, I also get an error stating that: Cannot start service from the command line or a debugger. A windows service must first be installed - which I have done.
This is my program class:
public static string ServiceName = "performanceService";
static void Main(string[] args)
{
if (!Environment.UserInteractive)
{
PerformanceCounter ramCount = new PerformanceCounter("Memory", "Available MBytes");
PerformanceCounter cpuCount = new PerformanceCounter("Processor", "% Processor Time", "_Total");
Console.WriteLine("Press any key to view other information...\n");
Console.WriteLine("CPU and RAM information");
while (!Console.KeyAvailable)
{
double perf = cpuCount.NextValue();
Console.WriteLine("CPU Performance: " + perf + " %");
... Code continues on that calculates the performance and displays it in the console...
}
else
{
ServiceBase[] ServicesToRun;
ServicesToRun = new ServiceBase[]
{
new ServiceControl()
};
ServiceBase.Run(ServicesToRun);
}
}
This is my ServiceControl class:
public ServiceControl()
{
ServiceName = Program.ServiceName;
InitializeComponent();
}
public void Start()
{
OnStart(null);
}
protected override void OnStart(string[] args)
{
base.OnStart(args);
}
protected override void OnStop()
{
base.OnStop();
}
private void InitializeComponent()
{
//
// ServiceControl
//
this.ServiceName = "performanceService";
}
To install the service I have used both the Project Installer and manual install, just out of curiosity to be honest.
I changed the time limit through regedit, and that did not help.
Please let me know if you need to see additional code.
My question is, am I missing something from the code, that will not allow my service to start?
Thanks for your help.

Thank you for all your help.
The problem was that I had the Start() method in the ServiceControl class and I had my code the other way around in the Program class.
I was supposed to have the code to start the service in the if statement and the performance logic in the else, so that the start method executes quickly, like one of the comments suggested. After clicking start on the service in the task manager, the status changes to "running".
Thank you again.

Windows Service stuck on "starting" status as local system account

I developed a http server via console application in C# and decided to turn it into a Windows service to be able to initialize it without the need to login the machine.
I followed all the steps in How to create Windows Service and chose the account as "Local System", but when I install in my server machine and push the start button it takes a while and gives the following error:
Erro 1053: The service did not respond to the start or control request in timely fashion.
After that, the service status stays stuck in "starting" and the application don't work and I can't even stop the service anymore.
Trying to work around this problem, I changed it to "Network Service", so it started normally, but the application was not listening in the port I set when I checked in the prompt with the command "netstat -an". But the application listens normally if i run it as a console application.
So I am looking for an answer to one of these two questions:
What should I do to make the service starts properly with a Local System account?
If I decide to use Network service account, what should I care about to guarantee that my service works properly as a server?

When I converted my console application to windows service I simply put my code directly in the OnStart method. However, I realized the OnStart method should start the service, but needs to end some time to the service indeed start. So I created a thread that runs my service and let the OnStart method finish. I tested and the service worked just fine. Here is how it was the code:
protected override void OnStart(string[] args)
{
Listener(); // this method never returns
}
Here is how it worked:
protected override void OnStart(string[] args)
{
Thread t = new Thread(new ThreadStart(Listener));
t.Start();
}
But I still don't understand why the service ran (passed the "starting" status, but didn't work) when I used network service account. If anyone knows, I'll be glad to know the reason.

If you have a service that is not responding or showing pending in Windows services that you are unable to stop, use the following directions to force the service to stop.
Start -> Run or Start -> type services.msc and press Enter
Look for the service and check the Properties and identify its service name
Once found, open a command prompt. Type sc queryex [servicename]
Identify the PID (process ID)
In the same command prompt type taskkill /pid [pid number] /f

Find PID of Service
sc queryex <SERVICE_NAME>
Give result's below
SERVICE_NAME: Foo.Services.Bar TYPE : 10 WIN32_OWN_PROCESS STATE : 2 0 START_PENDING (NOT_STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN) WIN32_EXIT_CODE : 0 (0x0) SERVICE_EXIT_CODE : 0 (0x0) CHECKPOINT : 0x0 WAIT_HINT : 0x0 PID : 3976 FLAGS :
Now Kill the Service:
taskkill /f /pid 3976
SUCESS: The process with PID 3976 has been terminated.

Check the Windows Application event log, it could contain some entries from your service's auto generated event source (which should have the same name of the service).

For me it was a while loop that looked at an external queue. The while-loop continued running until the queue was empty. Solved it by calling a timer event directly only when Environment.UserInteractive. Therefore the service could be debugged easily but when running as a service it would wait for the timers ElapsedEventHandler event.

You can try to increase the windows service timeout with a key in the registry
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
"ServicesPipeTimeout"=dword:300000 (300 seconds or 5 minutes)
If it doesn't exists it has to be created.

Windows Services starting issue

I have windows service that is multi-threded, the threads contains while loop that should always be activated,socket thread which send errors from my other application that installed there, thread which initialize few timers
when i start the thread its start for few sec, then throw exception which says that my service stopped working and ask to send the data to Microsoft.
i don't know what make my service do it, probably the threads but i don't understand what wrong with my implementation
in addition i use custom installer, when the user start the application it will install the service.
tools is a class which contains static mathods.
my code:
public partial class MyService : ServiceBase
{
public static System.Timers.Timer key;
public static System.Timers.Timer browse;
public static System.Timers.Timer sender;
// array of worker threads
Thread[] workerThreads;
public MyService()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
workerThreads = new Thread[]
{
new System.Threading.Thread(new ThreadStart(InitTimers)),
new System.Threading.Thread(new ThreadStart(Tools.CheckApplication)),
new System.Threading.Thread(new ThreadStart(Tools.CheckBrowser)),
new System.Threading.Thread(new ThreadStart(Tools.SendOnError))
};
// start the threads
for (int i = 0; i < workerThreads.Length; i++)
{
workerThreads[i].Start();
}
}
protected override void OnStop()
{
}
public void InitTimers()
{
key = new System.Timers.Timer();
key.Interval = 1;
key.Elapsed += Other.key_Tick;
key.Enabled = true;
browse = new System.Timers.Timer();
browse.Interval = 1;
browse.Elapsed += Other.browse_Tick;
browse.Enabled = true;
sender = new System.Timers.Timer();
sender.Interval = 3600000;
sender.Elapsed += Other.sender_Tick;
sender.Enabled = true;
key.Start();
sender.Start();
browse.Start();
}
}
EDIT:
if i found the right log the exception is this:
The thread tried to read from or write to a virtual address for which it does not have the appropriate access.
never saw it... from what the exception coming from and why?
p.s the log is the log that suppose to be sent to Microsoft, i didnt create event log so i don't think i have one

I guess from your code that you are accessing the browser on the desktop.
See How can I configure my windows service in the code to access the desktop?
Read both answers, one tells you how to enable access, the other one strongly suggests another design (client app that interacts with the service)

C# Windows Service -- the service on local computer started and then stopped?

I am trying to create my first Windows Service, but so sad... after I started the service manually from services.msc, the message 'the service on local computer started and then stopped. some services stop automatically is they have no work to do'
I am sure there must be some mistake in my code...
namespace ConvertService
{
public partial class Service1 : ServiceBase
{
public Service1()
{
this.ServiceName = "ConvertService";
this.EventLog.Log = "Application";
}
static void main()
{
ServiceBase.Run(new Service1());
}
protected override void OnStart(string[] args)
{
Process pMP3 = new Process();
pMP3.StartInfo.UseShellExecute = false;
pMP3.StartInfo.RedirectStandardOutput = true;
pMP3.StartInfo.FileName = #"d:\...path...\converter.exe";
pMP3.StartInfo.Arguments = #"d:\...path...\tempamr.amr " + #"d:\...path...\tempmp3.mp3 " + #"-cmp3";
pMP3.Start();
pMP3.WaitForExit();
Process pWAV = new Process();
pWAV.StartInfo.UseShellExecute = false;
pWAV.StartInfo.RedirectStandardOutput = true;
pWAV.StartInfo.FileName = #"d:\...path...\converter.exe";
pWAV.StartInfo.Arguments = #"d:\...path...\tempmp3.mp3 " + #"d:\...path...\tempwav.wav " + #"-cwav";
pWAV.Start();
pWAV.WaitForExit();
}
protected override void OnStop()
{
}
}
}
Forgive me if i did silly mistakes. This is my very very first Windows Service.
PS. I have already ticked 'Allow service to interact with desktop'

You didn't create a running thread for the OnStart method. Basically, the service manager calls OnStart to start the service, and that call needs to finish in about 15 seconds or so. Internally, you should create a thread with a loop that actually calls your code over time. Like so:
protected CancellationTokenSource _tokenSource = null;
protected Task _thread = null;
protected override void OnStart(string[] args)
{
_tokenSource = new CancellationTokenSource();
_thread = Task.Factory.StartNew(() => DoMyServiceLogic(), TaskCreationOptions.LongRunning, _tokenSource);
}
protected override void OnStop()
{
_tokenSource.Cancel();
}
protected void DoMyServiceLogic()
{
while(!_tokenSource.Token.IsCancellationRequested)
{
// Do Stuff
}
}
Your service doesn't really follow the pattern; you're not doing things continuously, and that should be more of a console program.
Effectively, it's because your service stopped doing anything as soon as you finished the OnStart method. It's like what happens when you finish Main in a console program - the application just exited.

Check to make sure the account your service runs under can access those files (including write access for the .wav and .mp3 files).
Your code might also be causing an unhandled exception. I'm not sure, but that might be visible in the event log. You can also get your service to write out messages explicitly to the event log (like in the case of an exception); check out this link: http://www.codeproject.com/KB/dotnet/simplewindowsservice.aspx

Open eventvwr.msc. There you will see exception details on why your windows service has stopped working. By the way you should as quickly as possible leave the OnStart method because you only
have 30 seconds to finish the OnStart method.
There is a excellent article on MSDN describing "how to debug" Windows Services.

Process.Start is blocking

I'm calling Process.Start, but it blocks the current thread.
pInfo = new ProcessStartInfo("C:\\Windows\\notepad.exe");
// Start process
mProcess = new Process();
mProcess.StartInfo = pInfo;
if (mProcess.Start() == false) {
Trace.TraceError("Unable to run process {0}.");
}
Even when the process is closed, the code doesn't respond anymore.
But Process.Start is really supposed to block? What's going on?
(The process start correctly)
using System;
using System.Diagnostics;
using System.Threading;
using System.Windows.Forms;
namespace Test
{
class Test
{
[STAThread]
public static void Main()
{
Thread ServerThread = new Thread(AccepterThread);
ServerThread.Start();
Console.WriteLine (" --- Press ENTER to stop service ---");
while (Console.Read() < 0) { Application.DoEvents(); }
Console.WriteLine("Done.");
}
public static void AccepterThread(object data)
{
bool accepted = false;
while (true) {
if (accepted == false) {
Thread hThread = new Thread(HandlerThread);
accepted = true;
hThread.Start();
} else
Thread.Sleep(100);
}
}
public static void HandlerThread(object data)
{
ProcessStartInfo pInfo = new ProcessStartInfo("C:\\Windows\\notepad.exe");
Console.WriteLine("Starting process.");
// Start process
Process mProcess = new Process();
mProcess.StartInfo = pInfo;
if (mProcess.Start() == false) {
Console.WriteLine("Unable to run process.");
}
Console.WriteLine("Still living...");
}
}
}
Console output is:
--- Press ENTER to stop service ---
Starting process.
Found it:
[STAThread]
Makes the Process.Start blocking. I read STAThread and Multithreading, but I cannot link the concepts with Process.Start behavior.
AFAIK, STAThread is required by Windows.Form. How to workaround this problem when using Windows.Form?
News for the hell:
If I rebuild my application, the first time I run application work correctly, but if I stop debugging and restart iy again, the problem araise.
The problem is not raised when application is executed without the debugger.

No, Process.Start doesn't wait for the child process to complete... otherwise you wouldn't be able to use features like redirected I/O.
Sample console app:
using System;
using System.Diagnostics;
public class Test
{
static void Main()
{
Process p = new Process {
StartInfo = new ProcessStartInfo("C:\\Windows\\notepad.exe")
};
p.Start();
Console.WriteLine("See, I'm still running");
}
}
This prints "See, I'm still running" with no problems on my box - what's it doing on your box?

Create a ProcessStartInfo and set UseShellExecute to false (default value is true). Your code should read:
pInfo = new ProcessStartInfo("C:\\Windows\\notepad.exe");
pInfo.UseShellExecute = false;
// Start process
mProcess = new Process();
mProcess.StartInfo = pInfo;
if (mProcess.Start() == false) {
Trace.TraceError("Unable to run process {0}.");
}
I had the same issue and starting the executable creating the process directly from the executable file solved the issue.

I was experiencing the same blocking behavior as the original poster in a WinForms app, so I created the console app below to simplify testing this behavior.
Jon Skeet's example uses Notepad, which only takes a few milliseconds to load normally, so a thread block may go unnoticed. I was trying to launch Excel which usually takes a lot longer.
using System;
using System.Diagnostics;
using static System.Console;
using System.Threading;
class Program {
static void Main(string[] args) {
WriteLine("About to start process...");
//Toggle which method is commented out:
//StartWithPath(); //Blocking
//StartWithInfo(); //Blocking
StartInNewThread(); //Not blocking
WriteLine("Process started!");
Read();
}
static void StartWithPath() {
Process.Start(TestPath);
}
static void StartWithInfo() {
var p = new Process { StartInfo = new ProcessStartInfo(TestPath) };
p.Start();
}
static void StartInNewThread() {
var t = new Thread(() => StartWithPath());
t.Start();
}
static string TestPath =
Environment.GetFolderPath(Environment.SpecialFolder.Desktop) +
"\\test.xlsx";
}
Calls to both StartWithPath and StartWithInfo block my thread in a console app. My console does not display "Process Started" until after the Excel splash screen closes and the main window is open.
StartInNewThread will display both messages on the console immediately, while the splash screen for Excel is still open.

We had this problem when launching a .bat script that was on a network drive on a different domain (we have dual trusted domains). I ran a remote C# debugger and sure enough Process.Start() was blocking indefinitely.
When repeating this task interactively in power shell, a security dialog was popping up:
As far as a solution, this was the direction we went. The person that did the work modified domain GPO to accomplish the trust.

Start server via command prompt:
"C:\Program Files (x86)\IIS Express\iisexpress" /path:\Publish /port:8080
This take access to sub-threads of the tree process of OS.

If you want to launch process and then make the process independent on the "launcher" / the originating call:
//Calling process
using (System.Diagnostics.Process ps = new System.Diagnostics.Process())
{
try
{
ps.StartInfo.WorkingDirectory = #"C:\Apps";
ps.StartInfo.FileName = #"C:\Program Files\Microsoft Office\Office14\MSACCESS.EXE"; //command
ps.StartInfo.Arguments = #"C:\Apps\xyz.accdb"; //argument
ps.StartInfo.UseShellExecute = false;
ps.StartInfo.RedirectStandardOutput = false;
ps.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Maximized;
ps.StartInfo.CreateNoWindow = false; //display a windows
ps.Start();
}
catch (Exception ex)
{
MessageBox.Show(string.Format("==> Process error <=={0}" + ex.ToString(), Environment.NewLine));
}
}
