vacko Posted April 16, 2012 Share Posted April 16, 2012 Hi, why $var return 1 ?Should be 0, isn't it ?Local $var = Ping("", 250) If $var Then MsgBox(0, "Status", "Online, roundtrip was: " & $var & " ms") Else MsgBox(0, "Status", "An error occured with number: " & @error & " ms") EndIfUsuallly nobody use empty address/hostname, but when address is variable returned by TCPNameToIP, it can become "" (when host is unreachable or PC where srcipt is running is offline).My AutoIT version is 3.3.8.1 Link to comment Share on other sites More sharing options...
jvanegmond Posted April 16, 2012 Share Posted April 16, 2012 (edited) TCPNameToIP returns "" when it gets an error. You should not try to ping "". It doesn't make sense (to expect a valid return value from a function that should fail). Instead try something like this: $ping_result = 1 $ip = TCPNameToIP("your host") If $ip <> "" Then $ping_result = Ping($ip, 250) EndIf Or: $ping_result = Ping("your host", 250) If $ping_result = 0 Then $ping_result = 1 Edited April 16, 2012 by Manadar github.com/jvanegmond Link to comment Share on other sites More sharing options...
guinness Posted April 16, 2012 Share Posted April 16, 2012 Obviously you would do some error checking before passing to Ping e.g. Local $sHostName = "" If StringStripWS($sHostName, 8) <> "" Then Local $iPing = Ping($sHostName, 250) If $iPing Then MsgBox(0, "", "Online, roundtrip was: " & $iPing & " ms") Else MsgBox(0, "", "An error occured with number: " & @error & " ms") EndIf Else MsgBox(0, "", "An error occured, hostname is blank.")

Returns 0 if host is not pingable or other network errors occurred and sets @error In my case, is host pingable or not ? No ! That's how I "begginer" understand it...

vacko Posted June 27, 2012 Author Share Posted June 27, 2012 (edited) Hi, except above "not a bug" I probably found real bug:If you boot your OS with LAN cable unplugged and use ping function (example as below)$result = Ping("8.8.8.8", 1000) MsgBox(262144,'Result','Return Value is: ' & $result & @lf & @lf & '@error code is: ' & @error )return value will be 1 and @error will be 0but corect return value should be 0 and @error should be 4 (or 1).I duplicated same issue under Windows 7, WinPE 3.0, WinPE 4.0Am I correct ?BTW, at same time, ping from command prompt return: PING: transmit failed. General failure. Edited August 26, 2012 by vacko Link to comment Share on other sites More sharing options...
