How to handle OnTimer event in Delphi XE2?

Question

I need to show a message say "Hi" everyday at 9 AM. Do I require Timer for this? How can I check whether its 9 AM or not. What should be the interval of timer at which OnTimer event run?

procedure Form1.TimerTimer1(Sender: TObject);
begin
  ShowMessage("Hi");
end;

If I run this event in after 24 hours, I fear it might pass 9 AM and will not fire.

Unless you have other valid reasons, it's far more easier to

• write a simple application that shows the message and quits
• schedule it to run using the task scheduler of Windows
