This document provides a tutorial on developing Windows services in C#. It discusses what a Windows service is, how to create a Windows service project in Visual Studio, add controls like FilesystemWatcher and Timer, install and start the service, and includes an example of using these components to restrict text files from being created in a specific directory. The tutorial is intended for beginners and provides step-by-step instructions and explanations of key concepts for creating a basic Windows service application in C#.

1. Hello friends

Part 45:
Windows services

2. • Windows service:
• windows service is the background process of the application(.exe) by
default windows service is supports cui features. a service is a program. a
program which is under control of windows os is called as windows service.
• windows service doesnot supports GUI features. but supports 2 gui
controls
• 1.Filesystemwatcher
• 2.timer(system.timers.timer)
• to develop windows services,.net provided a template is called as windows
service. all windows services will be stored in a location called as
"services";
• How to open services:
• start-controlpanel-Administrative tools-services.
• 2nd process:
• start-Run-services.msc
• Every windows service is a class,which must be inherited from
servicebase class. servicebase is the part of system.serviceprocess

3. • windows services contains 2 events
• 1.onstart()
• 2.onstop()
• 1.Filesystemwatcher:
• this control is used to get information about os files. this
controls gives information about created files, deleted files,
renamed files and changed files.
• properties:
• 1.path
• 2.filter
• 3.Includedsubdirectories
• 4.Enabledraisingevents

4. • events:
• 1.created
• 2.deleted
• 3.renamed
• 4.changed
• 2.timer(system.timers.timer):
• we can apply the continously action purpose using this control.
• properties:
• 1.enabled=true/false
• 2.interval
• events:
• 1.elapsed
• example on windows service (restrict the text files in the d location):
• we can develop windows service following these 4 steps
• 1.create windows service project
• 2.Addinstallers
• 3.install the service in services folder using installutil command.
• 4.start the service

5. • step 1:
• 1.create windows service project
• open visual studio 2012
• file -new-project-windows-windows service
• after getting service1.cs[design]
• in the service1.cs[design] add 2 controls
• 1.filesystemwatcher
• 2.timer(system.timers.timer)

6. • goto-filesystemwatcher-events-created(double click)
• goto-timer-properties-enabled=true interval=1000
• goto-timer-events-elapsed(double click)
• source code:
• private void fileSystemWatcher1_Created(object sender,
System.IO.FileSystemEventArgs e)
• { File.Delete(e.FullPath.ToString()); }
• private void timer1_Elapsed(object sender,
System.Timers.ElapsedEventArgs e)
• { fileSystemWatcher1.Path = "d:";
• fileSystemWatcher1.Filter = "*.txt";
• fileSystemWatcher1.IncludeSubdirectories = true;
• fileSystemWatcher1.EnableRaisingEvents = true;
• }

7. • goto-build-build solution-windowsservce1.exe
• copy the windowsservice1.exe
• E:7pmonlineWindowsService1WindowsService1binDebugWin
dowsService1.exe
• step 2:Add installers
• goto-service1.cs[design]-right click-Add installers after -getting-
projectinstaller.cs[design]
• in this design 2 controls are there
• 1.serviceinstaller1
• 2.serviceprocessinstaller1
• goto-serviceinstaller1-properties-servicename=suhashinifile
• starttype=manual
• goto-serviceproceeinstaller1-properties-account=localsystem

8. • goto-build-build solution-.exe
• step 3:
• install the service in services folder using installutil
command.
• installutil:
• using this we can install the service in the services
folder
• 1.-i(install)
• syntax:
• installutil -i ws.exe

9. • 2.-u(uninstall)
• syntax:
• installutil -u ws.exe
• open-vs-cross tools command-right-click-Run as Administrator
• c::e:
• e:>cd E:7pmonlineWindowsService1WindowsService1binDebug
• e:E:7pmonlineWindowsService1WindowsService1binDebug>
• 3.installutil -u ws.exe
• e:E:7pmonlineWindowsService1WindowsService1binDebug>
• installutil -i ws.exe
• the coomit phase successfully completed
• 4.start the service
• goto-services-start the service -suhashini-rightclick-start the service
