Here’s the real scoop: A service is a service is a service. That’s my motto. What I mean by that is I don’t care if you are using a C++ EXE, a VB exe, a C# EXE, some thunking host EXE such as SrvAny.exe… they all implement the same API’s to interact with the service … Read more
Cant be done*. In later Operating Systems that won’t work as Windows Services are disallowed from interacting with the Desktop – instead UI presented by Windows Services is shown in Session 0, a special logon session which is not normally visible to the end user.

The way to go is named pipes, you’ll probably have to take a look at the communication across different Integrity levels. This article explores how to do this in vista. Although it’s written in c++ it’s just basic Windows API calls, so it should translate fast enough to Delphi. If you want to search for … Read more
Playing a wav file from a service is definitely possible, at least on Windows 7 (and most likely Vista), by using the Windows Core Audio APIs. I recently verified this by making a small test service using NAudio. I just downloaded the NAudio sources and copied the “Wsapi” parts from their NAudioDemo project. This was … Read more
You might try disabling the timer during processing, something like // Just in case someone wants to inherit your class and lock it as well … private static object _padlock = new object(); try { serviceTimer.Stop(); lock (_padlock) { // do some heavy processing… } } finally { serviceTimer.Start(); } Edit : OP didn’t specify … Read more
(1) On first start, Set _timer.Interval to the amount of milliseconds between the service start and schedule time. This sample set schedule time to 7:00 a.m. as _scheduleTime = DateTime.Today.AddDays(1).AddHours(7); (2) On Timer_Elapsed, reset _timer.Interval to 24 hours (in milliseconds) if current interval is not 24 hours. System.Timers.Timer _timer; DateTime _scheduleTime; public WinService() { InitializeComponent(); … Read more
Add a reference to System.ServiceProcess.dll. Then you can use the ServiceController class. // Check whether the Alerter service is started. ServiceController sc = new ServiceController(); sc.ServiceName = “Alerter”; Console.WriteLine(“The Alerter service status is currently set to {0}”, sc.Status.ToString()); if (sc.Status == ServiceControllerStatus.Stopped) { // Start the service if the current status is stopped. Console.WriteLine(“Starting the … Read more
The reason that the UnhandledException event on the current AppDomain does not fire is how services are executed. User sends a Start command from the Windows Service Control Manager (SCM). The command is received by the framework’s ServiceBase implementation and dispatched to the OnStart method. The OnStart method is called. Any exception which is thrown … Read more
I agree with Romulo on finishing to start your service as soon as possible. However, if you need the time and you are using .NET Framework 2.0 or later, you might consider ServiceBase.RequestAdditionalTime() method. http://msdn.microsoft.com/en-us/library/system.serviceprocess.servicebase.requestadditionaltime.aspx protected override void OnStart() { this.RequestAdditionalTime(10000); // do your stuff }
