Creating Services with VB Express

 

Visual Basic Express is a great, free tool from Microsoft.   You don’t get all that Visual Studio 2005 offers though.  One of the things VB Express does not have is templates to create a Windows Service.  

We can still make Services with VB 2005 Express.  All it takes is a little manual work.  I will walk you thru a example on how to make a service in Visual Basic Express.

 

Choose Console Application, and give it the name of NewService1.

ServiceStart

 

It will open in the designer with a module. Rename the module to NewService1.

Now we have to get some references for our Service. In the solution Explorer, double click on My Project and choose the References tab. 

We need to Add the following references: 

System.Configuration.Install 
System.ServiceProcess

Now back to the NewService1 Module. We will be replacing all the text in the module, thus turning it into a class. Replace all the text with the text below:

1 Imports System.ServiceProcess

2 Imports System.Configuration.Install

3

4 Public Class NewService1

5 Inherits System.ServiceProcess.ServiceBase

6 Friend WithEvents Timer1 As System.Timers.Timer

7

8 Public Sub New()

9 MyBase.New()

10 InitializeComponents()

11 ‘ TODO: Add any further initialization code

12 End Sub

13

14 Private Sub InitializeComponents()

15 Me.ServiceName = “NewService1”

16 Me.AutoLog = True

17 Me.CanStop = True

18 Me.Timer1 = New System.Timers.Timer()

19 Me.Timer1.Interval = 6000

20 Me.Timer1.Enabled = True

21 End Sub

22

23 ‘ This method starts the service.

24 <MTAThread()> Shared Sub Main()

25 ‘ To run more than one service you have to add them to the array

26 System.ServiceProcess.ServiceBase.Run(New System.ServiceProcess.ServiceBase() _

27 {New NewService1})

28 End Sub

29

30 ‘ Clean up any resources being used.

31 Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)

32 MyBase.Dispose(disposing)

33 ‘ TODO: Add cleanup code here (if required)

34 End Sub

35

36 Protected Overrides Sub OnStart(ByVal args() As String)

37 ‘ TODO: Add start code here (if required)

38 ‘ to start your service.

39 Me.Timer1.Enabled = True

40 End Sub

41

42 Protected Overrides Sub OnStop()

43 ‘ TODO: Add tear-down code here (if required)

44 ‘ to stop your service.

45 Me.Timer1.Enabled = False

46 End Sub

47

48 Private Sub InitializeComponent()

49 Me.Timer1 = New System.Timers.Timer

50 CType(Me.Timer1, _ System.ComponentModel.ISupportInitialize).BeginInit()

51

52 ‘Timer1

53

54 Me.Timer1.Enabled = True

55 CType(Me.Timer1, System.ComponentModel.ISupportInitialize).EndInit()

56 End Sub

57

58 Private Sub Timer1_Elapsed(ByVal sender As System.Object, ByVal e As _ System.Timers.ElapsedEventArgs) Handles Timer1.Elapsed

59 Dim MyLog As New EventLog() ‘ create a new event log

60 ‘ Check if the the Event Log Exists

61 If Not MyLog.SourceExists(“NewService1”) Then

62 MyLog.CreateEventSource(“NewService1”, “NewService1 Log”) ‘ Create Log

63 End If

64 MyLog.Source = “NewService1”

65 MyLog.WriteEntry(“NewService1 Log”, “It is running”, EventLogEntryType.Information)

66

67 ‘disable the timer so you dont fill up the log

68 Timer1.Enabled = False

69 End Sub

70

71 End Class

72


This will create the NewService class and insert a Timer into your designer. 
If you Double-Click on the NewService1 in the SolutionExplorer, you will see the designer and the Timer1 object. 

This code will run after 6 seconds has passed, and will insert a log entry for our service saying “ It is running”. 

We need to set the Service Name in the Designer: 

Double click on NewService1 to get the gray page. Then click somewhere in the grey to get the properties for this class. 

Under ServiceName put NewService1.

ServiceGrayTimer
