No, that only checks if a different computer is online, it automatically returns 5 whether this computer is on or not. (i want to see if THIS computer has a current internet connection, not a different computer. thanks anyways

OK ... understand what you meand now...

Could you check the @IPAddress1 thru @IPAddress4 to see if it gets and address assigned from you ISP ?

here we are (untested)

Edit: Tested! I inverted the 0 and the 1, ops... Now works.

Func _IsThisComputerConnected()

; A function to know if a computer is connected or not.
; Returns
; 0 if the computer is Offline
; 1 if the computer is Online

Local $ping
Local $computername

$computername = "www.altavista.com";----Altavista seems a good computer to check... :)

; Changed -w to 5000 because a "out-of-LAN" computer can need more time.
RunWait(@comspec & " /c ping "& $computername &" -n 1 -w 5000>"& @tempdir &"\ping.tmp","",@sw_hide)
$ping = FileReadLine(@tempdir &"\ping.tmp",13)
FileDelete(@tempdir &"\ping.tmp")
If StringInStr($ping,"(0%") Then
   Return 1
Else
   Return 0
EndIf
EndFunc

You are forgetting an important, but easy to miss, fact that someone's computer may be behind a proxy. Then the ping command would never be successfull...it's not for me.

There is an API command for getting internet connection status.

If you're simply checking your connectivity to the internet .. then why not just run a URLDownloadToFile (of say, www.google.com) .. and check the results?

There is an API call to check if computer is connected to the internet.

Any plans on incorporating it?
