Hi,

you can use windows service for this...

1. Create a widnows service

2. set timer for particluar time

3. write you functionality in time eplased event fo the timer.

I think You have stored the data in you database. After 5 days you can put that code while your system starts. or you can use your Sql Server triggering technique. As trigger fires on the sql server side. It will send the message to the user. You can write that stored procedure to send mail.

Other technique is that u can create a web service and deploy that service on your mail server. As, this service is instantly running it will check data time of system (SERVER) and sends mail to the user.

protected bool mSendMail()

string strText = "YourText "

try

MailMessage mail = new MailMessage();

mail.To ="address@domain.com";

mail.Cc = cc@domain.com;

mail.From = Author@domain.com;

mail.Subject = "Auto Generated Mail - Software Requirement from " + DDept.Text;

string MailBody = string.Format("Requirement from: {0} <br><br> Delivery Date: {1} <br><br> Type of Requirements: {2} <br><br> Requirement Details: {3} <br><br> Contact Person: {4} <br><br> Contact Manager: {5}", txtUserName.Text, txtDeliveryDate.Text, DType.Text, txtARequir.Value, txtContactPerson.Text, DManager.Text);

mail.BodyFormat = MailFormat.Html;

for (int i = 0; i < attachments.Count; i++)

mail.Attachments.Add(new MailAttachment(attachments[i]));

SmtpMail.SmtpServer="YourDomainSMTPServer";

SmtpMail.Send(mail);

return true;

}catch(Exception ex)

string strMessage = "<script language=JavaScript>alert('Unable to make Connection with local Mail Server '+ "+ex.ToString()+")</Script>";

Page.RegisterStartupScript("WinScript", strMessage);

return false;

Check this link which is explaining similar requirement..

You can follow the inputs from here togo ahead with your requirement

1. The following is the code to send mail.

add reference to System.Web.dlll

add

using System.Web.Mail;

then you can use  the

a) MailMessage Object
b) SmtpMail Object

somthing like this

                                MailMessage mvMail= new MailMessage();
                        mvMail.To  ="itsumapathyk@gmail.com";
                        mvMail.From  =itsumapathyk@gmail.com;
                        mvMail.Body="test";
                        mvMail.Subject = "test s";
Must Note:
You have to specify the a valid  SmtpServer for this to work and you must have the rights on this server

                        SmtpMail.SmtpServer  = "bslnt";
                        SmtpMail.Send(mvMail);

2. Create a windows application with this code

3.  add a scheduler to scheduled task and set the specific time you want it to run.

For that you have to Use WINDOWS SERVICE.

Its easy just go thr these steps;    

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() };

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 = "<font face='verdana' color='#FF9900'><b>"+"Hi "+dr["emp_name"].ToString()+"," + "</b></font><br><br>";

mailtxt=mailtxt+"<font face='verdana' color='#FF0000'><b>"+"Good Day." + "</b></font><br><br>";

mailtxt=mailtxt+"<font face='verdana' color='#008080'><b>"+"May today be filled with sunshine and smile, laughter and love." + "</b></font><br><br>";

mailtxt=mailtxt+"<font face='verdana' color='#0000FF'><b>Cheers!" + "<br><br>";

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.

Best Luck!!!!!!!!!!!!!!!!!

Hi,

I'm jeevalatha.........

i want a some of the sourcecode for automatic email system..........

Note:

          we are making payment to the vendors by ECS or NEFT.Once payment is made we need to communicate the vendor about the payment made.Currently this task is carried out by our traditional mailing system.

          I have to decide to automate this process by developing web application in asp.net....I think this new application will reduce the delay in communication with the vendor regarding the payment made.....And also reduce the paper work and dispatch work......

          I'm waiting for ur rly.......plz reply to me with in two days
