Creating Services with Visual Studio 2008


A Windows services is a application that runs in the background.  There is documentation on the Web for creating a Service with Visual Studio 2003, but is is changed for VS 2005, and 2008.


I will walk thru a sample Service in Visual Studio 2008.  This should also work with VS 2005.



Create the Service.





From Visual Studio Start Page, choose create project…   Select Windows Service and give it a name of NewService.



First thing we will do is add a timer to the Service.  DO NOT USE THE TIMER IN THE TOOLBOX.  The Timer for Windows Forms does not work for Services.  We will have to find the System.Timers.Timer component by right clicking on the Toolbox, and Choose Items.

Find the one that matches below:


Click OK.  This will put the Timer into the Printing section of the Toolbar for some reason.


From The Service1 designer.  Click on Timer1, and set the interval to 10000 (10 Seconds).  Then Double-click to open Code View for Timer1_Elapsed.

Add the Following Code to the Timer1_Elapsed:

Dim MyLog As New EventLog() 
‘ create a new event log 
‘ Check if the the Event Log Exists

If Not MyLog.SourceExists(“NewService”) Then 
MyLog.CreateEventSource(“NewService”, “NewService_Log”) ‘ Create Log
End If 

MyLog.Source = “NewService” ‘ Write to the Log 
MyLog.WriteEntry(“NewService_Log”, “Service is Running” _ , EventLogEntryType.Information)

End Sub


And For OnStart():


Protected Overrides Sub OnStart(ByVal args() As String)
‘ Add code here to start your service. This method should set things 
‘ in motion so your service can do its work. 

Timer1.Enabled = True
End Sub


Now is normally where you would hit Run to start and debug your app.  This is not the case with Windows Services.  We have to add a few things called Installers to make them work correctly.
