title: VB.net prevent a tooltip from showing
body: <p>In my program i use tooltips to help new users have some idea of what the icon buttons do. I also have an option to turn tooltips off.</p>
  
  <p>There appears to be a <code>tooltip.hide</code> method, but i don't quite understand how to use it.</p>
  
  <p>So how do i get a tooltip to not display if a boolean value is set to false.</p>
