阅读更多关于 Check if no user is currently logged on to Windows

One of the tasks ensures no user is currently logged on, locks the workstation, delete some files, and then restarts the system. I considered using this solution to look through the list of running processes and check the user names, determining if no user is logged on by matchhing the user names against

How does a Windows service differ from a standard exe?

阅读更多关于 How does a Windows service differ from a standard exe?

问题 What's the difference between a Windows service and a standard exe? 回答1: A windows service always runs once the computer starts up (as long as it's so configured). A standard EXE only runs when a user is logged in, and will stop if the user logs out. You would use a windows service for things that always need to run even if nobody is logged in. You would use a standard EXE for programs that a user will run while logged in. 回答2: A Windows service has a special ServiceMain function and must

Forcing windows to wait for a service to stop when it is shutting down

阅读更多关于 Forcing windows to wait for a service to stop when it is shutting down

I'm having an issue that I can't figure out regarding a Windows Service I have written in C#. What I am trying to do is wait for a specified period for a child process to terminate before I am forced to kill it and stop the service. I have set my timeout for anywhere from 5 to 15 seconds and my service waits the appropriate amount of time and then kills the child and stops when I stop it via the mmc service window. However if I shutdown the computer my service gets blown away before it is able to wait and stop properly. I have read that Windows allows for a timeout of 30 seconds for a service

Access Denied when executing Process.Start from Windows Service

阅读更多关于 Access Denied when executing Process.Start from Windows Service

I'm trying to run a process from the service as another user. Process.Start(applicationPath, params, account, SecureStringPassword, ""); A service is running under the "Local System" account. The account parameter is a string like "WORKSTATION6\Tester". This user is a member of the Administrators group. "Application Path" refers to Program Files, so every user can read from it. But I have an "Access Denied" Exception every time I try to start the process. What can you advice? There is an example of how to use Process.Start on the SecureString page. http://msdn.microsoft.com/en-us/library

SQL “login failed for user [username]” error for windows service, but SSMS login works

阅读更多关于 SQL “login failed for user [username]” error for windows service, but SSMS login works

I'm writing a windows service that needs to connect to a SQL server to retrieve some information. However, the server doesn't allow me to connect: login failed for user [domain/username] . The strange part is that everything works totally fine from inside SSMS. I can log in, query the database, and everything works out perfectly. It's only through the windows service that it's throwing that error. For reference, here's the connection string I'm using: Data Source=sqlserveraddresshere;Initial Catalog=databasenamehere;User ID=domain\username;Password=password` I doubt that this is related, but
