Going Crazy

29 posts in this topic

OK I am going crazy with StingRegExp. I have to be missing something. It is giving me a positive match for a SINGLE letter of the string to look for. So if I tell it to look for "pass" and the search string contains password it returns positive. Why does it not match EXACT!? I am not looking for partial matches, I need exact, case sensitive as well. 

Any thoughts?

$inBoundip = $sClientIPAddress
    $inBoundData = TCPRecv ($iSocket, 5)
    If $inBoundData=="login" Then
        TCPSend ($iSocket, "success")
        $inBoundData = TCPRecv ($iSocket, 2048)
    $convert = BinaryToString ($inBoundData)

    $convert2 = BinaryToString (_EncDec(0, $convert))
    $stringtosplit = StringSplit($convert2, "#")
    $username = $stringtosplit[1]
    $password = $stringtosplit[2]
    $path = "C:\accounts\" & $username & "\" & $username & ".txt"
    $accountExists = FileExists ($path)
    If $accountExists == 1 Then
        $datafile = FileRead ($path)
        $chckpass = StringRegExp($datafile, $password)

The string it is evaluating is a text file containing other data including a password. I am searching the entire data file to see if $password exist in it. So if the users password is "password" and its inside the data file and $password = "pass" or "pa" or "word" or any character it returns true. It should be able to see that "pass" is not an exact match to "password".

kudrow,

Something like this perhaps: ;)

$sKey = "blah"

Global $aString[3] = ["BlahblahBlah", " blah", "blah"]

For $i = 0 To 2
    If StringRegExp($aString[$i], "^" & $sKey & "$") Then
        ConsoleWrite("Found" & @CRLF)
    Else
        ConsoleWrite("Not Found" & @CRLF)
    EndIf
Next

This is how I would do it

$sKey = "pa"
 
Global $aString[3] = ["pass", " password", "pa"]
 
For $i = 0 To 2
    If $aString[$i] == $sKey Then
        ConsoleWrite("Found" & @CRLF)
    Else
        ConsoleWrite("Not Found" & @CRLF)
    EndIf
Next

I agree with J1 : StringInStr should suffice, no ?

Also, be careful to special chars (reserved chars of RegExp) in your key that you want to search to. You should use "Q" & $sKey & "E" To match something like P@$$w0rd+

I truly believe that the == is the fastest absolute test.

Thank you for the replies everyone. I did try StingInStr before I posted for help and received the same results. I received positive returns on partial matches. I am going to evaluate the examples yall provided above to see if I can understand them and then test them. Thanks again everyone for the help!

I am a little confused. $password can be anything. It is actually a string from a login GUI. I take this string and use it as the pattern to search for. So if a users stored password is "AutoITRocks" and they enter (for example) "Auto" in the password field of the GUI, it returns a true value based on the partial match.

The string it is evaluating is a text file containing other data including a password. I am searching the entire data file to see if $password exist in it.

 

So "==" will obviously don't do the trick, either StringInStr because it will match "pa" in "password" - requirements quite clear in OP's post #3

$Password = "pass"
$data = " big sting of data including the pissward password inside as well as the shorter pass word"

If StringInStr($data, " " & $Password & " ") Then
    MsgBox(0, "Woo", "Hoooo!")
EndIf

Maybe:

StringRegExp($string, "\b\Q" & $password & "\E\b")

?

Edit:

or exact match:

StringRegExp($string, "^\b\Q" & $password & "\E\z")

Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer.

Where's your pattern?

looks like you just need StringInStr.

The pattern is $password

I am going to throw that out there, look in my signature for PasswordValid to check the validity of the password too e.g. enough digits, lowercase chars etc.

If StringInStr($data, " " & $Password & " ") Then
    MsgBox(0, "Woo", "Hoooo!")
EndIf

 

Ok so this is looking for spaces on either side of the variable $password correct?

Yes, I suppose it's a rather poor example

 

No it's not. 

It is essentially the same as

Stringregexp($data, '\b\Q' & $Password & '\E\b')

as suggested earlier.

The OP's problem was not making the match restrictive enough.

      Well the plan is to use the power of regular expressions engine of AutoIT for patching binary data.
      Something like this: StringRegExp( $BinaryData,  "(?s)\x55\x8B.."
       
      <cut> ... Okay straight to question/problem
      ... certain bytes that are in the range from 0x80 to 0xA0 won't match.
      Hmm seem to be a char encoding problem. In detail these are 27 chars: 0x80, 0x82~8C, 0x8E, 0x91~9C, 0x9E,0x9F
      Here's a small code snippet to explore / explain this problem:
      #include "StringConstants.au3" $TestData = BinaryToString("0x7E7F808182") ;Okay $match = StringRegExp( $TestData ,'\x7E' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Okay $match = StringRegExp( $TestData ,'\x7F' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Error no match $match = StringRegExp( $TestData ,'\x80' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Okay $match = StringRegExp( $TestData ,'\x81' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Error no match $match = StringRegExp( $TestData ,'\x82' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;~ output: ;~ @extended = 2 $match = ;~ @extended = 3 $match = ;~ @extended = 0 $match = 1 ;~ @extended = 5 $match = ;~ @extended = 0 $match = 1 Hmm what to do? Go back and use the 'numberstring monster' implementation or just omit that range of 'unsafe bytes'. What is the root of this problem?
      Any idea how to fix this?
       
      Update: Okay I know a byte is not a character.
      But StringRegExp operates on String and so character level.
      Okay as long as you stay at Ansi encoding and only use /x00 - /X7F in the search pattern using  StringRegExp works well to search for binary data.
      What bytes can be matched that are in the range from /X7F - /xFF is also depending on the code page.
      So this avoid to search for bytes in the range from 0x80-0xa0 only applies to Germany.
      I just change this country setting:

      to Thai and now near all bytes from /X7F - /xFF fails to match.

      Hello,
      I have spent the past day fooling with StringRegExp to no avail attempting to get what would be a simple solution to an issue using StringRegExp.
      I will post the code in a sec. The string 'Java x Update y' where x and y are numeric values ONLY if a letter is mixed in anywhere then it should fail. I have been able to successfully deal with the x value so if x = 1234 or a1234 or 1a234 or 1234a would result in a fail if 'a' was in the string. However, when y = 1a234 then I get an output of 1 and when y = 1234a then the output = 1234 when both should fail. I am probably overlooking something simple and in looking through all the material and experimenting I am unable to figure it out and my experience with stringregexp and trying to find examples of this proved difficult. If someone could assist or point me to a thread ? Here is my code ; prob a simple fix. I am also trying to avoid white spaces.
      Thanks in advance

      Does anyone know how to split a string using multiple delimiters, returning both the values and delimiters withing the Array using StringRegExp?  For example:
      ;~ Split on " Not ", " And ", " Or " $sString = ' Not $a = 1 And $b = 2 Or $b = 3' $aArray = StringRegExp($sString,...) ;~ Returned Results $aArray[0] = '$a = 1' $aArray[1] = 'And' $aArray[2] = '$b = 2' $aArray[3] = 'Or' $aArray[4] = '$b = 3' At the moment I'm using
      Local $aArray1 = StringRegExp($sString, '(?i) Or | And | Not ', 3) Creating a new array using string split and then joining the two arrays together again
      Local $aArray1 = StringSplit(StringRegExpReplace($sString, '(?i) Or | And | Not ', '******'), '******', 3) Unfortunately regular expression isn't my forte.
