Question about StringRegExp

[Moze]

Hello i'm kinda noob at programing and trying to make function that will check if string is valid IP address. i use StringRegExp. At moment pattern that i wrote is:

StringRegExp("192.168.1.1", '\A[1-255]\.[0-255]\.[0-255]\.[0-255]\z', 0)

But it does not work. Please help me to make a good pattern that will match a valid ip address.

P.S. English isn't my native language...

There is an example of this on the regular-expressions.info example page:

Thankyou for replay

You could also say "Screw regular expressions!":

$testip = "300.50.50.50"

MsgBox(0,"",validIP($testIP))

;Return 0 if valid
;Return 1 if ip has too many or too few bytes
;Return 2 if any byte is out of range
Func validIP($ip)
    $ipArray = StringSplit($ip,".")

    If $ipArray[0] <> 4 Then
        Return(1)
    EndIf

    For $X = 1 to 4
        If $ipArray[$X] < 0 OR $ipArray[$X] > 255 Then
            Return(2)
        EndIf
    Next

    Return(0)
EndFunc

Minor correction on weaponx script:

The first part of an IP address can't be 0 while any other can be, so the script need to be just a little "tuned" for $ipArray [1] which needs to be >0 and <255
