title: Update form from timer event handler
body: <p>I have a form (Form1) and this form has a <code>System.Timers.Timer</code> object. I'd like to Invalidate the form (Basically this is my goal, to Invalidate (call <code>Invalidate()</code>) the form every once in a while where timeout period changes each time when event is triggered). However since event handler method is static, I don't have access to instance of my form. </p>
  
  <p>How can I pass some objects to my event handler?</p>
