One way is, You could use a timer executing every second (for example) and check current date-time

Hi Boopal.,
Try this!
using System;
using System.Windows.Forms;
namespace SerialNumberReset
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
tbSerialNumber.Text = GetSerialNumber().ToString();
}
private int GetSerialNumber()
{
if (DateTime.Now.Date > Properties.Settings.Default.ReferenceDate.Date)
{
Properties.Settings.Default.ReferenceDate = DateTime.Now;
return 1;
}
else
{
return Properties.Settings.Default.SerialNumber;
}
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
Properties.Settings.Default.Save();
}
private void buttonUpdateSerialNumber_Click(object sender, EventArgs e)
{
Properties.Settings.Default.SerialNumber = GetSerialNumber() + 1;
tbSerialNumber.Text = Properties.Settings.Default.SerialNumber.ToString();
}
}
}
Try this!
using System;
using System.Windows.Forms;
namespace SerialNumberReset
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)

Properties.Settings.Default.ReferenceDate = DateTime.Now;
return 1;

else
{
return Properties.Settings.Default.SerialNumber;
}

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
Properties.Settings.Default.Save();

private void buttonUpdateSerialNumber_Click(object sender, EventArgs e)

Hi,
You can try this:
Add key inside app.config file of your windows application as follows:
<configuration>
<appSettings>
<add key="Date" value="15-05-2016"/>
</appSettings>
</configuration>
.CS code:
Using System.Configuration;
string szOldDate= ConfigurationManager.AppSettings["Date"].ToString();
Compare Datetime.Now and szOldDate
If Datetime.Now > szOldDate then reset serial_No = 1;
Else serial_No = serial_No + 1;

How you plan to store the Serial number?. It is just display only.
If you are plan to store the Serial number in SQL Server/Simple Text File you have have the table having the columns "Date" and Serail number.
You can increase the serial number by checking the current date. Following the the logic you can use.
1. Select DBdate,Serialnumber from TableName where DBdate = Current date
2. If you find the record in the above query, you can increase the current serial number and use it.
3. If you did not find record in the above query, Insert one record with current date and serial number = 1
By using the above logic you can reset the serial number based on current date
