Hi,

This is Ravindra, Implemented a windows service in one of my project and like to place a

sample Windows service for the very Basic users of .Net.

First Create a table in Msaccess with Name 'Empdata'

1.Open Visual Studio.net > Select New Project

2.Select Windows Service and give Name as 'GoodDay' and Click Ok.

3.Right Click the Design and Select Properties and give the Name and ServiceName as

'GoodDay' and set AutoLog to 'True'

4.Drag and drop the OleDbConnection and Select its properties and change its name to

'conn' and provide the connection String(I provided the Database sample(Ms

Access)) along with this code.

5.Right Click the Design and select View Code and

Select Project > Add Reference > Select System.Web >Press Ok

6.Now add the following to your code

using System.Web.Mail;

using System.Data.OleDb;

7.Declare DateTime mdt=DateTime.Now;

8. In static void Main()

Edit the following Code

ServicesToRun = new System.ServiceProcess.ServiceBase[] { new GoodDay() };

9. Edit the following code in onstart()

DataSet ds = new DataSet();

protected override void OnStart(string[] args)

{

DateTime dt=DateTime.Now;

conn.Open();

OleDbDataAdapter da=new OleDbDataAdapter("select * from Empdata",conn);

da.Fill(ds);

if(dt.ToShortDateString()==mdt.ToShortDateString())

{

foreach(DataRow dr in ds.Tables[0].Rows)

{

mdt=DateTime.Now.AddDays(+1);

String mailtxt="";

MailMessage mm = new MailMessage();

mm.BodyFormat = MailFormat.Html;

mm.To = dr["emp_email"].ToString();

mm.From = "xyz@xyz.com";

mm.Subject="Good Day";

mailtxt = ""+"Hi "+dr["emp_name"].ToString()+"," + " ";

mailtxt=mailtxt+""+"Good Day." + " ";

mailtxt=mailtxt+""+"May today be filled with sunshine and smile, laughter and love." + " ";

mailtxt=mailtxt+"Cheers!" + " ";

mm.Body = mailtxt;

SmtpMail.SmtpServer="localhost";

SmtpMail.Send(mm);

}

}

}

10.Go to Design,right click and Select Add Installer ,you will notice two controls

 serviceProcessInstaller1,serviceInstaller1

11.Select serviceProcessInstaller1 and go to its properties and change the Account

 type to 'Local System'

12. Select serviceInstaller1 and go to its properties and change DisplayName and

 ServiceName to 'GoodDay' and make the StartType to 'Automatic'

13.Build the Solution(Cntrl+Shift+B)

14.Open the Visual Studio .Net Command Prompt and give the path of application
 for example C:\bin\Debug and then type InstallUtil GoodDay.exe
 to uninstall, InstallUtil /u GoodDay.exe



15. After Installation ,right click My Computer and
 Select 'Manage'
 and Select 'Service and Applications'
 and in that Select 'Services'
Select 'GoodDay' and start the Service.
