title: Visual Basic - Checking if a port is open
body: <p>Ok, I'm making a Visual Basic GUI application to display whether a number of my ports are open for people to know whether things like my website and my Minecraft server are open.</p>
  
  <p>My problem is I have absolutely no idea how to do this in Visual Basic.</p>
  
  <p>Basically, I'm asking for something which sends a signal to an IP with a specific port, if it is open then return true, if it's closed, return false. Similar to: <a href="http://www.canyouseeme.org/" rel="nofollow">http://www.canyouseeme.org/</a></p>
