I would like to know few cases here I run the application and I set the date to date time picker as current date on form load. Now I change the system date so at that time do you need to close your form or when your application started running and in the form load you want to check and close the form?

private void dateTimePicker1_ValueChanged(object sender EventArgs e) { DateTime changedDate = dateTimePicker1.Value; if (DateTime.Now.CompareTo(changedDate) == 0) { MessageBox.Show(Same values); } else { MessageBox.Show(Changed values); Application.Exit(); Environment.Exit(0); } }
