I found several errors in the code that you reused and have fixed these and also cleaned it up a little. Again, the original code is taken from here. public static class ServiceInstaller { private const int STANDARD_RIGHTS_REQUIRED = 0xF0000; private const int SERVICE_WIN32_OWN_PROCESS = 0x00000010; [StructLayout(LayoutKind.Sequential)] private class SERVICE_STATUS { public int dwServiceType = … Read more
Here’s my take on the issue: using System; using System.Collections.Generic; using System.Runtime.InteropServices; namespace EnumerateRDUsers { class Program { [DllImport(“wtsapi32.dll”)] static extern IntPtr WTSOpenServer([MarshalAs(UnmanagedType.LPStr)] string pServerName); [DllImport(“wtsapi32.dll”)] static extern void WTSCloseServer(IntPtr hServer); [DllImport(“wtsapi32.dll”)] static extern Int32 WTSEnumerateSessions( IntPtr hServer, [MarshalAs(UnmanagedType.U4)] Int32 Reserved, [MarshalAs(UnmanagedType.U4)] Int32 Version, ref IntPtr ppSessionInfo, [MarshalAs(UnmanagedType.U4)] ref Int32 pCount); [DllImport(“wtsapi32.dll”)] static extern void … Read more
This is a WMI query to get the user name: ManagementObjectSearcher searcher = new ManagementObjectSearcher(“SELECT UserName FROM Win32_ComputerSystem”); ManagementObjectCollection collection = searcher.Get(); string username = (string)collection.Cast<ManagementBaseObject>().First()[“UserName”]; You will need to add System.Management under References manually.
Below I have put together everything I learned about Starting/Stopping a Windows Service from a non-Admin user account, if anyone needs to know. Primarily, there are two ways in which to Start / Stop a Windows Service. 1. Directly accessing the service through logon Windows user account. 2. Accessing the service through IIS using Network … Read more
System.Diagnostics.Trace.WriteLine(Directory.GetCurrentDirectory()); will output the current directory. Put that code in the startup method of your service and use a tool like DebugView to check the output. Then you will know the startup folder of your service. This simple technique will be useful with many problems in service development, especially to debug service startup. You probably … Read more
I guess something like this would work: Add System.ServiceProcess to your project references (It’s on the .NET tab). using System.ServiceProcess; ServiceController sc = new ServiceController(SERVICENAME); switch (sc.Status) { case ServiceControllerStatus.Running: return “Running”; case ServiceControllerStatus.Stopped: return “Stopped”; case ServiceControllerStatus.Paused: return “Paused”; case ServiceControllerStatus.StopPending: return “Stopping”; case ServiceControllerStatus.StartPending: return “Starting”; default: return “Status Changing”; } Edit: There … Read more
Set the service to restart after failure (double click the service in the control panel and have a look around on those tabs – I forget the name of it). Then, anytime you want the service to restart, just call Environment.Exit(1) (or any non-zero return) and the OS will restart it for you.
I usually use the following techinque to run the same app as a console application or as a service: using System.ServiceProcess public static class Program { #region Nested classes to support running as service public const string ServiceName = “MyService”; public class Service : ServiceBase { public Service() { ServiceName = Program.ServiceName; } protected override … Read more
The problem with Shrike’s answer is that it does not work with a user connected over RDP. Here is my solution, which properly determines the current user’s session before creating the process. It has been tested to work on XP and 7. https://github.com/murrayju/CreateProcessAsUser Everything you need is wrapped up into a single .NET class with … Read more
This will never work, at least not under Windows Vista or later. The key problem is that you’re trying to execute this from within a Windows Service, rather than a standard Windows application. The code you’ve shown will work perfectly in a Windows Forms, WPF, or Console application, but it won’t work at all in … Read more
