all the code I copied from microsoft company, even the top of the page I posted without you reading my first questions, now you give the same link from microsoft company. Before you criticize others, have you tried my example ?
If you pass in a host name, the Send method calls Dns.GetHostAddresses[^] and pings the first address returned.
If you want to force it to ping the IPv4 address - assuming there is one - then you'll need to call Dns.GetHostAddresses yourself. You can then find the address you want to ping, and pass that into the Send method instead of the host name.
No it doesn't; you're simply calculating a value based on whether or not it's an IPv4 address, and sorting on that value. So long as the value returned for an IPv4 address is less than the value returned for other addresses, OrderBy will sort them correctly.

First of all, that is not a special red line, nor is that a progress bar. That is merely a horizontal line, that you can draw—or even better you can configure a border for the bottom or top control to be shown as a red solid line.
Secondly, this is a ProgressBar, that control in the picture is not. That control is known as a Slider, that lets your users slide across a range of values.
What should I install in the visual studio ?
That depends on what you already have. Most of the controls are framework-based, such as WinForms or WPF. You need to download the specific framework and then develop the app in that framework.
There are some UI control providers too, such as Telerik, Infragistics, etc. that can help you author the UI using the controls that may not be available in the framework. But this depends on your use case, what framework do you have?
