How to ping a site

[lock255]

Hi I am creating a program that does ping a website, so what I need is:
1) Know whether the site is online
2) the IP address of the server
If someone helps me I'd be really grateful. I just started programming with B4A, so I ask you spieghermi things in a simple and step by step.

Ping might require ROOT privileges, that's why only works in debug mode.

There is no way to insert the privileges in the Manifest?

Unfortunately, no.

Thank you all for the help, the only step is how to establish by ping if a website is up or down. Anyone is capable of it?

Debug mode doesn't add ROOT privileges. It does however add the INTERNET permission. You should manually add it with the manifest editor:

AddPermission(android.permission.INTERNET)

Indeed, I forgot about that permission.

The Ping now works fine, but I want to understand how to determine whether a website is up or down?

You should use HttpUtils2 to "download" the Url. If it is successful then the website is up.

Erel, could you please email me the code to do the download?

 

[NJDude]

You can search for it, type httputils2 up in the SEARCH box and you'll find it.

I managed to do just that:

Sub Check_Click
MainUrl= "http://www." & LinkSito.Text
   PreviewWeb.LoadUrl(MainUrl)
   Dim job As HttpJob
   job.Initialize("Main page", Me)
   job.Download(MainUrl)
End Sub

I do not know how to let him know if the download page has been done (so the site is up) or it is not possible to download (when the site is down).

Erel the PreviewWeb does not give me problems, I can not write the statement that allows you to check if the page download is successful or not.

 

[Erel]

Check HttpUtils2 tutorial. You should handle JobDone event and check Job.Success.
