title: building a reminder in winform
body: <p>I am a student and working on <code>winform c#</code>. I have a small app and I want to add a new feature of memo reminder. For example, when I type something in a text box, the app saves it and set a timer of 8 hours. If the app is running, then a message should popup with the message I have saved.</p>
  
  <p>It's not clear to me if I should use a database for reminding the entries or something else provided by c#. As far as I know all thing are automated. Is there anything which will help me to build this functionality, like a timer??</p>
