Alarming Software

Question

I wish to know whether there is an Alarming Software or Alerting Software. For example if I have a Doctor appointment on a particular day, if I want my computer to alert me one or two days before that particular day. When I switch on the computer it will alert me by audio voice or by an alarm.

Answer 1

Here is my idea on your project

Answer 2

There is a problem in your code - but it will take some time to work it out.
Soon as I get somewhere, I'll post result

Answer 3

Thank you for that code to compare if the ID is already in the array list.  They should not both go straight to the last name the lastStudent button should go straight to the last name but as for the nextStudent button it should display a different student every time until the end of the array list.  But what I am having trouble with is that when I click the nextStudentButton I can continue to click until the end of the array not the last student.  

Answer 4

When I use either button- it moves to last name ?
As to check id try this

 public void checkId()
{
foreach (Student stu in students)
{
if (stu.IdNumber.ToString() == idAddTextBox.Text)
{
MessageBox.Show("Sorry.Student id already in use");
return;
}
}
}
