Question

I am using Microsoft Visual C# 2010 Express. I did not have access to a Windows Services template so I downloaded one online. I am trying to implement a timer into my project and I am getting the following errors.

Error 1 Invalid token ‘=’ in class, struct, or interface member
declaration C:\Documents and Settings\bruser\My Documents\Visual
Studio 2010\Projects\WindowsService\Service1.cs 19 23 windowsservice

Error 2 Method must have a return type C:\Documents and
Settings\bruser\My Documents\Visual Studio
2010\Projects\WindowsService\Service1.cs 19 29 windowsservice

Error 3 The type or namespace name ‘timer’ could not be found (are you
missing a using directive or an assembly reference?) C:\Documents and
Settings\bruser\My Documents\Visual Studio
2010\Projects\WindowsService\Service1.cs 19 17 windowsservice

Error 4 The name ‘timer’ does not exist in the current
context C:\Documents and Settings\bruser\My Documents\Visual Studio
2010\Projects\WindowsService\Service1.cs 23 4 windowsservice

Error 5 The name ‘OnElapsedTime’ does not exist in the current
context C:\Documents and Settings\bruser\My Documents\Visual Studio
2010\Projects\WindowsService\Service1.cs 23 45 windowsservice

Error 6 The name ‘timer’ does not exist in the current
context C:\Documents and Settings\bruser\My Documents\Visual Studio
2010\Projects\WindowsService\Service1.cs 24 13 windowsservice

Error 7 The name ‘timer’ does not exist in the current
context C:\Documents and Settings\bruser\My Documents\Visual Studio
2010\Projects\WindowsService\Service1.cs 25 13 windowsservice

Service1.cs

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.ServiceProcess;
using System.Text;
using System.Timers; 

namespace SendFax
{
public partial class Service1: ServiceBase
{
    public Service1()
    {
        InitializeComponent();
    }

    private timer = new Timer();

    protected override void OnStart(string[] args)
    {
        timer.Elapsed += new ElapsedEventHandler(OnElapsedTime);
        timer.Interval = 30000; // every 30 seconds
        timer.Enabled = true;

    }

    protected override void OnStop()
    {
        // TODO: Add code here to perform any tear-down necessary to stop your service.
    }
    }
    }

The namespace in both Program.cs and Service1.cs were named $SaveNamespace$. So, I changed both of them to SendFax. Should these two files have separate namespace names?

I changed onElapsedTime to Tick. Do the namespaces need to be named different on Program.cs and Service1.cs?

Answer 1

You are missing the variable type here.

private timer = new Timer();

Try:

private Timer timer = new Timer();
