windows-services

问题 First off, I'd like to say that I've used StackOverflow for years, and this is the first time I haven't found an existing answer. A testament to what a valuable resource this is. Background: I'm trying to catch MIDI input from a connected device and have it trigger keyboard events to whichever window has focus. I was able to do this successfully using SendInput in a Windows Console application, but would prefer to run this as a service. I was able to hide the console window and have it work,

问题 Here is my scenario, I have a windows service that runs a task every 20 minutes, the task is: requesting updates from an API hosted by a remote website. The response is a list of JSON objects, When the Service receives the list, it carries out a set of operations then appends more JSON objects, finally the service must push the list to a running console application. My very specific question is : how to transfer this data from the windows service to the console App both directly and

问题 I have a project where I need to create a windows service that, when instructed via a command, will perform various tasks. This server would run on multiple servers and would effectively perform the same kind of tasks when requested. For example, I would like to have a Web API service that listens for requests from the servers. The service running on the server would send a query to Web API every 25 secs or so and pass to it its SERVERNAME. The Web API logic will then look up the SERVERNAME

问题 I have a Windows service written in C# with the .NET 2.0 framework that uses the FileSystemWatcher to monitor certain directories for changes. Some of these directories may be on removable media, such as a USB drive. When a new drive is plugged into the system, I get notification through a WMI query and can set up a new FileSystemWatcher. All that works well. The difficulty is that I want the user to be able to eject the drive using the Windows "Safely Remove Hardware" app, but Windows

问题 I am creating a Windows service. When an exception occurrs, I handle it appropriately and create a log. I am using the decorator pattern, as there are many different ways people will be looking at these logs. I have an email logger, a file logger, and a windows event logger, all which inherit from LoggingDecorator, which implements ILogger. So, no logger knows about any other logger. My question is: How should I handle logging exceptions? If writing to a file fails, or sending an email fails,

问题 I have a custom Installer class that is used when installing my Windows Service. Stripped down to the necessary details the class looks like this. [RunInstaller(true)] public class MyWindowsServiceInstaller : Installer { public MyWindowsServiceInstaller() { ServiceProcessInstaller processInstaller = new ServiceProcessInstaller(); ServiceInstaller serviceInstaller = new ServiceInstaller(); processInstaller.Account = ServiceAccount.LocalSystem; serviceInstaller.DisplayName = Program

问题 I wrote a C# Windows Service to handle task scheduling for our application. I'm trying to move the "business rules" assemblies into a bin subdirectory of the scheduling application to make it easier for us to do updates (stop service, delete all files in bin folder, replace with new ones, start service). I added <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <probing privatePath="bin;"/> </assemblyBinding> </runtime> to the service's app config and it works fine if the

问题 A consultant setup a windows service to run a application. The application is supposed to run every 15 minutes. The application is not running at all and the service appears to be running fine. I am not familiar with how an application will run at a standard interval when running as a service. The service uses the SRVANY.EXE tool. 回答1: Any 'consultant' that sets up a service to run using SRVANY.EXE should be fired. SRVANY is an unfortunate hack that should have been retired a decade ago; it

问题 What are windows services? How are they different from other .NET application? Any references or examples are welcome which sight the differences 回答1: Windows service is a Windows concept and generally does not really have anything to do with .NET per se other than that these could be written in .NET languages. The main difference between a service and an ordinary windows app Services always run (usually started when computer boots; depending on design, you can manually stop or start these)

问题 I need my service to check for existence and structure of certain files during its startup and exit/fail/stop if some conditions aren't met. I read this thread: What is the proper way for a Windows service to fail? but it does not help. I set the ServiceBase.ExitCode property non-zero and then call ServiceBase.Stop. But I get 5 event log entries. See below: Starting service. (I log this event via code) Config.xml file not found. (I log this ERROR event via code) Service stopped successfully.
