I understand that you are willing to help beginners, but please...
Code
Public Class Form1
Rename the form, please. Not a problem, just an habit to take.

Code
Handles Button1.Click
I know this is the only button on the whole form, but again, if it's aimed to beginners, you should name it.

Code
My.Computer.Network.Ping(TextBox1.Text)
Same thing about control name, but you got the point.
The real problem here, is the use of the Microsoft.VisualBasic.MyServes namespace (In the form of My.*), which is a port of an old VB6 namespace, and thus shouldn't be used anymore (Heck, we are at .Net 4.5.1 dude).

Just in term of dependencies, I believe (according to MSDN) that it requires the VB6 runtime to be ran. Not a big deal in anyway, just something to be pointed out.

I can't be bothered to open up VS & to check for this, but in most cases, Microsoft.VisualBasic methods are wrappers for actual .Net function, and thus are not the best in term of optimization.
Here is what you should use instead: http://msdn.microsoft.com/fr-fr/library/7hzczzed(v=vs.110).aspx

This is in no way intended as an offense, I'm just pointing out what needs to be pointed out.

Thank you so much for this, I was still using the 'my' method of pinging a network. But thanks to you, I was able to choose a range of different options that has helped me create many different network applications. 😁

Wrong, First you say it's an old Vb6 namespace, and then you say it's a wrapper for .net? lol.
It's a wrapper for the WinAPI, just like .Net itself, everything is basically.

You're correct when you said it shouldn't be used anymore, at least within .net.

The title is missleading. I thought that it shows online status of a client.

Whats the difference of going to that website and seeing if it will work?

Because this is a desktop application. Some people are lazy. 😉
