I have a window service which plays a sound file at a specified time, so to do that I have taken Timer but it's Tick event is never fired, same is working in WinForm application.
Below is the code snippet of my service...
public partial class ClockService : ServiceBase
{
private TimeSpan _alarmTime = new TimeSpan(9, 55, 0);
private int _snoozeTime = 2; // 2 minutes
private int _repeatCounter = -1;
private const int ALARM_REPETITION = 5;
private string _alarmSoundPath = @"C:\Sound\default.wav";
private string _alarmLogPath = @"C:\Sound\log.txt";
public ClockService()
{
InitializeComponent();
alarmTimer.Enabled = true;
}
protected override void OnStart(string[] args)
{
using (FileStream fileStream = new FileStream(_alarmLogPath, FileMode.OpenOrCreate))
{
using (StreamWriter writer = new StreamWriter(fileStream))
{
writer.WriteLine("Service has started at {0}", DateTime.Now);
}
}
}
protected override void OnStop()
{
using (FileStream fileStream = new FileStream(_alarmLogPath, FileMode.OpenOrCreate))
{
using (StreamWriter writer = new StreamWriter(fileStream))
{
writer.WriteLine("Service has stopped at {0}", DateTime.Now);
}
}
}
private void alarmTimer_Tick(object sender, EventArgs e)
{
using (FileStream fileStream = new FileStream(_alarmLogPath, FileMode.OpenOrCreate))
{
using (StreamWriter writer = new StreamWriter(fileStream))
{
writer.WriteLine("Alarm time is: {0}", _alarmTime);
}
}
TimeSpan currentTime = new TimeSpan(DateTime.Now.TimeOfDay.Hours, DateTime.Now.TimeOfDay.Minutes, DateTime.Now.TimeOfDay.Seconds);
if (currentTime == _alarmTime)
{
using (FileStream fileStream = new FileStream(_alarmLogPath, FileMode.OpenOrCreate))
{
using (StreamWriter writer = new StreamWriter(fileStream))
{
writer.WriteLine("Alarm time is: {0} and current time is: {1}", _alarmTime, currentTime);
}
}
_alarmTime = _alarmTime.Add(new TimeSpan(0, _snoozeTime, 0));
_repeatCounter++;
if (File.Exists(_alarmSoundPath))
{
SoundPlayer player = new SoundPlayer(_alarmSoundPath);
player.PlayLooping();
}
}
if (_repeatCounter == ALARM_REPETITION)
{
_alarmTime = _alarmTime.Subtract(new TimeSpan(0, (ALARM_REPETITION * _snoozeTime), 0));
_repeatCounter = 0;
}
}
}
To make sure that I have done everything properly, here is my InitializeComponent method
private void InitializeComponent()
{
this.components = new System.ComponentModel.Container();
this.alarmTimer = new System.Windows.Forms.Timer(this.components);
this.alarmTimer.Enabled = true;
this.alarmTimer.Interval = 1000;
this.alarmTimer.Tick += new System.EventHandler(this.alarmTimer_Tick);
this.ServiceName = "PravoAlarmService";
}
Please anyone have a look and guide me...problem is the tick event is never fired..
