Запустите службу Windows и запустите cmd

Question

Должен ли я включить интерактивный дескрипт для его работы и что такое правильный код для запуска окна EXE или cmd? Я все еще не могу запустить службу, даже когда я разрешил ей взаимодействовать с рабочим столом.

Я бы использовал механизм чата, поэтому его проще управлять в качестве службы Windows.

Что случилось с моим кодом?

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.ServiceProcess; 
using System.Diagnostics; 
using System.ComponentModel; 
using System.Threading; 

namespace MyNewService 
{ 
    class Program : ServiceBase 
    { 
     static void Main(string[] args) 
     { 
     } 

     public Program() 
     { 
      this.ServiceName = "Chatter"; 
     } 

     protected override void OnStart(string[] args) 
     { 
      base.OnStart(args); 

      //TODO: place your start code here 
      ThreadStart starter = new ThreadStart(bw_DoWork); 
      Thread t = new Thread(starter); 
      t.Start(); 

     } 

     private void bw_DoWork() 
     { 
      Process p = new Process(); 
      p.StartInfo = new ProcessStartInfo(@"C:\Windows\system32\cmd.exe"); 
      p.Start(); 
      p.WaitForExit(); 
      base.Stop(); 
     } 

     protected override void OnStop() 
     { 
      base.OnStop(); 

      //TODO: clean up any variables and stop any threads 
     } 
    } 
} 

Answer 1

Я пережил всю эту боль.

В Windows 7/Vista/2008 невозможно загрузить любой интерактивный процесс из службы - без вызова ряда Win API. = BLACK MAGIC

Посмотрите here и here.

ниже код делает трюк, использовать его с своим страхом и риском:

Answer 2

Когда работает как сервис, вы не сможете запускать все, что должно взаимодействовать с рабочим столом или породит это собственные окна.

Как сказал Aliostad, вам необходимо вызвать вызовы Win API для CreateProcessAsUser и эмулировать пользователя, чтобы он работал. Это включает в себя эмуляцию зарегистрированного пользователя и использование их учетных данных для «подъема» вашего процесса в уровень изоляции процесса 1 (который дает вам доступ к системе окон и тому подобным графическим процессорам).

Я делаю это в приложении, которое я написал, и это делает работу, но я согласен с Aliostad есть немного черная магия происходит, и это вообще отстой

Сказав все это, вы можете икру рабочих процессов из в рамках службы, поскольку они не требуют вещей, которые находятся в процессе изоляции уровня 1 (Windowing, GPU и т. д.)

cmd.exe по умолчанию будет пытаться создать окно, поэтому ваш пример не работает , Вы можете установить следующие свойства ProcessStartInfo, чтобы заставить его работать.

CreateNoWindow WindowStyle

Я написал службу сторожевого приложений, которые просто перезапускает приложение (в моем случае окно консоли App).

1. Я нашел очень хороший Hands-On Lab Учебное пособие (в C++), который я пытался на нее работал Session 0 Isolation на: http://msdn.microsoft.com/en-us/Windows7TrainingCourse_Win7Session0Isolation

2. я преобразовал, что образец C++ в C#. После нескольких тестов это сработало. До тех пор, пока я остаюсь включенным и не выхожу из системы и не войду снова, этот код работает отлично. Я должен сделать немного, чтобы поймать сеанс Logout/Login. Но для простого входа в систему и условий работы в Windows сторожевой таймер работает так, как ожидалось.
