I have created a windows appliction where we store login,logout and status(in or out) details of an employee depending on employee id.

Now my requirement is to send an email(local server) automatically for every half an hour consisting the employee details from DB where status value is "IN" .

Could any please help on how to proceed further.

Add a Timer to your form, which fires every minute.
In the Timer Tick handler, check a counter - start with 30 and count it down. When it reaches zero, you need to send the email.
See here for a generic method to do that: Sending an Email in C# with or without attachments: generic routine.[^] then set the counter back to 30 ready for next time.

thank you for the post.. Using the timer is ok. But how about fetching the records from database and send them as an attachment basing on the condition where status = "in".

Use your prefered DB access method (DataAdapter, or Connection/Command pair with a Reader) with the following query:
You then rework them into an appropriate format - I don't know how you need the email organised so I can't suggest anything much at this stage.

Sorry about the cross-over comments - I really must refresh my screen more often

You could use StringBuilder to construct the body of the email rather than an attachment - or write the text to a temporary text file and attach that to the email e.g. filename = "\"" + Path.Combine(Path.GetTempPath(), Path.GetRandomFileName()).ToString() + "\"";

Alternative if you want the email functionality separate from your UI ...

For sending an email you could use SMTP - System.Net.Mail This link[^] is a little old but covers various other methods too.

For the timing side of things (non-GUI) you could use System.Timers or System.Threading.Timer

or (if appropriate to your system) you could use the windows Task Scheduler[^] with your own code or a script e.g.[^]
