There is a specific engine called SAPIEN PowerShell V5 Host (Windows Service) make sure this is the engine selected under the Script Engine section: Script Engine To package your project with SAPIEN Script Packager, have the project open and open the packager settings from either the Deploy tab (Deploy->Packager) or (Home->Build and Run): Deploy->Packager Home->Build and Run

To make a real Windows service, you need to package your script with a PowerShell Windows Service engine. This script itself does not operate as a service, but you can dot source it from a test script to execute the functions for testing. All files set to include will be combined into one file called 1. When running a project, the project files are built based on their build setting and build order. Building and Running a Windows Service Project This is only important if additional files are added to the project and if the order in which the files are combined matters. The only project setting on this file that can be changed is the Build Order. When you first create a Windows Service project, a PSPROJ and PSS file are created:Īll functions mentioned above reside in Startup.pss. Again, this is only applicable if your service loop is utilizing $global:bServicePaused. This will resume your service’s main loop. # Service is being continued from a paused state Continue-MyService function Continue-MyService It is a good idea to sleep for longer periods between loop iterations when the service is paused this helps to prevent excessive CPU usage by simply waiting and looping. While your service is paused, the thread your script is running on is not suspended instead, the service loop is not running. This functionality is handled by you in the service loop as part of the Invoke-MyService function if this is not included, your service will not pause as expected. This function pauses your service’s main loop and suspends your service. # It is your responsibility in the service loop to pause processing until a 'continue' command is issued. # Note that the thread your PowerShell script is running on is not suspended on 'pause'. The script itself does not operate as a service, but you could dot source it from a test script to execute the functions for testing. Make sure you terminate running jobs and secondary runspaces here otherwise the service process may hang and not exit properly.īecause some modules create their own threads, jobs, runspaces, etc., it is also a good idea to use the Remove-Module command for any modules you load implicitly or explicitly. It’s important to note that the main service thread is forcefully terminated after you exit the Stop-MyService function.

Place code here to close connections and release resources. You can see some management code in here that will allow your main service loop to exit gracefully. This function is called when your service is asked to stop by the operating system or when using the Stop-Service command. # Place code to be executed on service stop here Start-Sleep -Seconds 1 # wait for your main loop to exit While($global:bServiceRunning -and $Countdown -gt 0) $CountDown = 30 # Maximum wait for loop to exit $global:bRunService = $false # Signal main loop to exit This function will run continuously as your service runs, following a process–sleep–process cycle. This is your service’s main loop, where the main functionality of your service takes place. Start-Sleep –Seconds 10 # a lower number will make your service active more often and use more CPU cycles Start-Sleep -Seconds 20 # if the service is paused we sleep longer between checks. # Adjust sleep timing to determine how often your service becomes active. If($global:bServicePaused -eq $false) #Only act if service is not paused Invoke-MyService function Invoke-MyService You should place all initialization code for your service here, such as opening connections or initializing global variables. This function is called when your service starts. The functions are as follows: Start-MyService function Start-MyService It’s important to note that you should not rename or omit any of the predefined functions when using this template because they are used when packaging with the SAPIEN Script Packager. This script template is also included in PrimalScript. You can use this template as part of a project or as a stand-alone script. The Windows Service Project utilizes the same predefined functions used by the single file Windows Service Script template. The Windows Service Project template allows you to create a Windows service script in a project: Services can start automatically when the system boots or they can start on demand-as requested by applications that rely on them. Windows Services are programs that run in the background, with no user interaction.
