stringsplit + stringleft

[gcue]

im trying to determine the first two quartets for my ip (and seperate each quartet into two vars)

i was doing this (which works for ips with two digits in each quartet):

$myIP = StringLeft(_GetIP(), 5)

$myaIP = StringLeft($myIP, 2)

$mybIP = StringRight($myIP, 2)

but this wont account for sets that have 3 digits =/

AAA.BBB.CCC.DDD

i figure id need something with stringsplit which would use the "." as a delimiter.. but theres multiple "."!!!

any ideas?

You want the first two quartets? Just StringSplit on '.' and read indexes 1 and 2. That's much easier if you ask me.

$firsttwoarray = StringSplit("192.168.2.88", ".")

$firsttwo = $firsttwoarray[1] & "." & $firsttwoarray[2]

And there's always the RegExp way:

#include <INet.au3>
$aIP = StringRegExp(_GetIP(), "([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)", 3)
If Not @error Then _
    ConsoleWrite(StringFormat("1:(%03d)\t2:(%03d)\t3:(%03d)\t4:(%03d)\n", $aIP[0], $aIP[1], $aIP[2], $aIP[3]))

([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)

not so good you can give more than 3 digits per quarter

\A([0-9]{1,3})\.([0-9]{1,3})\.([0-9]{1,3})\.([0-9]{1,3})\z

is better ( The String must only consist out of the IP, too

i just did

$mIP = StringSplit(_GetIP(), ".")

$myIP = $mIP[1] & "." & $mIP[2]

forsee any issues?

Yes, _GetIP() gets the ip from an external website so if the computer is offline there will be no array so $mIP[1] will cause a crash.

Rather do:

$mIP = StringSplit(_GetIP(), ".")
If Not @error Then
$myIP = $mIP[1] & "." & $mIP[2]
Else
$myIP="127.0"
EndIf

Edit: Fixed code

Well given that _GetIP() returns a valid IP or -1, I didn't think I needed to be too strict with greediness.

Whoever said that there can be more than 3 digits in a quartet is an idiot. The range per quartet is 0-255 inclusive.
