get variable name

25 posts in this topic

hello =)

is there any way to get a variable's name as it is passed through a function?

ie: 

$final_result = "4652"

Get_Variable($final_result)

Func Get_Variable($variable="") 
Endfunc

how do i get "$final_result"?

i know Get_Variable("$final_result", $final_result)  would give me both the variable name and value but i'm trying to see if there's another way

thanks in advance!

Why would you want to do that? There seems no logical reason in my book.

There is no other way that I am aware of, you'd have to write it yourself to tell you what variable you're passing. And as you've demonstrated, it's not that hard to do.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

debugging purposes.. if i am printing out multiple variables - trying to get a clearer picture of what im looking at - instead of just results for multiple variables.

If you can do that, it will be very easy to decompile AutoItScript.
I do not like this! :mad:

You,

AutoIt is hardly the most secure language in the first place - I really do not feel that this functionality (were it ever to be incorporated) would make a lot of difference.

So I would expect that someone will solve this issue and your script will never be safe again.

Or feel free to if you feel it is unnecessary.

I believe that you have never tried to decompiling few AutoIt programs.

I do not want someone to edit my script without my permission.
I did learn how to AutoIt work. It is easy to decompile.
I choose the solution is use Obfuscator.
Of course, nothing is safe absolutely.


Discussions or actions that violate rules are not welcome.

P/S: I said earlier that "deCompile" I mean "deObfuscator"

Seriously doubt anything written in AutoIt is going to ever be any more secure than anything written in any other language. Obfuscator's are NOT security, it's just changing variable/function names, no one cares what you called a variable, it's what the variable contains that's important.

Yeah, I also believe it is not safe.
But Obfuscator not just rename the variables and functions.
 

My program when Obfuscated: NetworkAdapterInfo_Obfuscated.au3
I do not think anybody wants to decompile and deObfuscator it.

Everyone,

$final_result = "4652"

msgbox(0, '' , Get_Variable("4652"))

Func Get_Variable($Value)

return StringRegExp(fileread(@ScriptFullPath) , '(\$.*?) = "' & $Value & '"' , 3)[0]

Endfunc

 

And all the conversation about this adding an attack vector is nonsensical

hi iamtheky,

that only works if something like this statement exists..

$final_result = "4652"

but wont work if something like this exists..

$final_result = stringreplace($string, "car", "")

very creative try though!

Indeed: plenty of problems here. 

Global $final_result = "1234"

For $i = 0 To 1
    WhatIs($final_result)
Next

Func WhatIs(ByRef $vThis)
    msgbox(0, '' , Get_Variable($vThis))
    $vThis -= 1
EndFunc

Func Get_Variable($Value)
    Local $aRet = StringRegExp(fileread(@ScriptFullPath) , '(\$.*?) = "' & $Value & '"' , 3)
    Return @error ? False : $aRet[0]
Endfunc

Not work:

Global $final_result = MyVariable()

MsgBox(0, Get_Variable($final_result), Get_Variable("4652"))

Func Get_Variable($Value)
    Local $aRet = StringRegExp(fileread(@ScriptFullPath) , '(\$.*?) = "' & $Value & '"' , 3)
    Return @error ? False : $aRet[0]
Endfunc

Func MyVariable()
;~  Return BinaryToString('0x34353632')
    Return "4652"
EndFunc

Are we really listing all the ways it doesnt work?  Instead of acknowledging that I aced an answer to Post #1 at slot #13, yall had nothing but bloviating about safety.  Im about to include the scope creep at #16 ftw too.
