windows服务与前台交互

1.问题描述

最近遇上一个难题,我写了一个windows服务,想要与桌面可以进行交互,设置了属性在运行一点反应也没有。

2.解决方案

   查找出来的解决方案有以下这些(一个代码块一个):

 

 1 [RunInstaller(true)]
 2     public partial class ProjectInstaller : System.Configuration.Install.Installer
 3     {
 4         public ProjectInstaller()
 5         {
 6             InitializeComponent();
 7         }
 8 
 9         protected override void OnAfterInstall(IDictionary savedState)
10         {
11             try
12             {
13                 base.OnAfterInstall(savedState);
14                 System.Management.ManagementObject myService = new System.Management.ManagementObject(
15                     string.Format("Win32_Service.Name='{0}'", this.serviceInstaller1.ServiceName));
16                 System.Management.ManagementBaseObject changeMethod = myService.GetMethodParameters("Change");
17                 changeMethod["DesktopInteract"] = true;
18                 System.Management.ManagementBaseObject OutParam = myService.InvokeMethod("Change", changeMethod, null);
19             }
20             catch (Exception)
21             {
22             }
23         }
24     }

 1 protected override void OnCommitted(System.Collections.IDictionary savedState)
 2         {
 3             base.OnCommitted(savedState);
 4 
 5             using (RegistryKey ckey = Registry.LocalMachine.OpenSubKey(@"SYSTEMCurrentControlSetServices" + Constants.ServiceName, true))
 6             {
 7                 if (ckey != null)
 8                 {
 9                     if (ckey.GetValue("Type") != null)
10                     {
11                         ckey.SetValue("Type", (((int)ckey.GetValue("Type")) | 256));
12                     }
13                 }
14             }
15         }

1 @echo "准备停止服务程序..."
2 sc stop TestService 
3 @echo "设置允许与桌面进行交互方式允许"
4 sc config TestService type= interact type= own
5 @echo "正在重新启动服务..."
6 sc start TestService 
7 @echo "启动服务成功!"

经验证,那个都无法实现服务与前台交互,桑心T0T........

3.最终版

   问题解决方案:由于windwos系统的升级,对权限划分更加明确,我们需要进行Sessoin 0穿透隔离,但是什么是Session 0呢?

   http://www.cnblogs.com/gnielee/archive/2010/04/07/session0-isolation-part1.html(大神详解,就不班门弄斧了)

ps:部分代码及结果展示

 1  //个人理解Session0是开启系统就出现的系统级别的“用户”,即使没有任何用户登录,这个“用户”也是自动“登录”的,这个应该叫“老板”即 Session 0,其他的才叫桌面用户:管理员、A用户、B用户、其他的远程用户等等,都是非Session0级别的。
