{
Timer timer1 = new Timer();
SqlConnection cn = new SqlConnection(" Server=localhos t;Database=xyz; Integrated Security=false; User Id=x;Password=y ;");
SqlConnection cn1 = new SqlConnection(" Server=localhos t;Database=xyz; Integrated Security=false; User Id=x;Password=y ;");

public Service1()
{
InitializeCompo nent();
}

protected override void OnStart(string[] args)
{
this.timer1.Ena bled = true;
this.Call_Me();

timer1.Elapsed += new ElapsedEventHan dler(OnElapsedT ime);
timer1.Interval = 1000;
timer1.Enabled = true;
}

protected override void OnStop()
{
this.timer1.Ena bled = false;
}

private void Call_Me()
{
SqlCommand command = null;
SqlDataReader reader = null;
string curdate = TimeZone.Curren tTimeZone.ToUni versalTime(Date Time.Now).AddHo urs(-5).ToString();
try
{
cn.Open();
command = new SqlCommand("sel ect p.project_id,n. entered_date,n. record_id,n.not e_id from project AS p INNER JOIN notes as n on p.project_id=n. project_id where p.status_id=10 and n.note_id in(select max(note_id) from notes group by project_id) order by 1", cn);
reader = command.Execute Reader();
while (reader.Read())
{
TimeSpan span = Convert.ToDateT ime(curdate).Su btract(Convert. ToDateTime(read er[1]));
//code to send emails exactly after 2days..
if (span.Days * 24 * 60 * 60 + span.Hours * 60 * 60 + span.Minutes * 60 + span.Seconds >= 172800 && reader[2].ToString() == "")
