what is the best way to compare files

7 posts in this topic

What i am trying to do is compare date of destination and source, and if source file is newer than destination it copies the file to source.

Just posting a sample code of what i am trying to achieve


#include <Date.au3> ; Include Date constants
#include <File.au3>
#include <iNet.au3>
#include <_XMLDomWrapper.au3>

Global $xml1, $xml1monthday, $xml1year, $xml1format, $xml2, $xml2monthday, $xml2year, $xml2format, $xmldate

; Runs the XmlDate() function to determine the age of the Xml file

Func XmlDate()
$Xml1 = RegRead("C:\Temp\m1.xml","XmlDate") ; pulls registry

$xml1monthday = StringTrimRight($xml1, 5) ; takes the month

$xml1year = StringTrimLeft($xml1, 6) ; takes the year out

$xml1format = ($xml1monthday & "/" & $xml1year) ; reorders the date

$Xml2 = RegRead("C:\Temp\m2.xml","XmlDate") ; pulls registry

$xml2monthday = StringTrimRight($xml2, 5) ; takes the month and

$xml2year = StringTrimLeft($xml2, 6) ; takes the year out

$xml2format = ($xml2monthday & "/" & $xml2year) ; reorders

if $Xml1 = "" And $Xml2 = "" Then
   FileCopy( "C:\temp\a1.txt", "C:\temp\anokh", 1);



Any comments will be appreciated 

Thank you

Have you looked at these functions? They are in the help file.

FileGetTime ( "filename" [, option = 0 [, format = 0]] )
FileGetVersion ( "filename" [, "stringname"] )

Or... I just found this one that I've used before.

#include <Misc.au3>
_VersionCompare ( $sVersion1, $sVersion2 )

@RickB75 Thank you

I think i will use Filegettime

if versioncompare has to be used,don't we have to add a version number in files?? i cannot edit existing files.

If you can use FileGetTime, you should be able to use 

StringCompare ( "string1", "string2" [, casesense = 0] )

to compare the two strings.

      Scite comes up occasional, almost incidentally, in some support topics.  I have not found a "Scite" topic in the forums, so this is where I will start.  I have recently been using Scite intensively, specifically with a large project and I have certain issues.  I know that Scite is not an AutoIt product, but it is so closely integrated to the core release that it makes sense to raise issues and request support here.  If this is not the right please refer me to the right forum.

      Hello. Im trying to make my scripts safe - unnable to decompile. I search for obfuscators and other security methods but the search has come to nothing.
      Then one guy gave that idea below. If I rightly understood this idea lets we talk about example program with this secutiy method.
      Program have two parts, first is only login gui and the second part is the main program Second part (main program) is uploaded on ftp server lets say that on http://xxx/autoit/main_program.au3 So we have the first gui with login, we put correctly login and pass and this is the moment when code from http://xxx/autoit/main_program.au3 will be downloaded and executed Finally main program will be appear This is the similiar way like new games are protected by cracking.
      I have few questions in this moment about this:
      Is something like that even possible to do with the autoit? First part of program (login gui) must have somewhere given that link to download the rest of code - http://xxx/autoit/main_program.au3 to make it execute. As we know this first part of program is easy able to hack and retrieve this web url http://xxx/autoit/main_program.au3 where located is main part of program. Is the way to encrypt or secure it? If only code will be stored in .php we know it cannot be previewed. So it could for example get code from .php file instead of .au3 I know that methods works in other languages (I dont know exactly how) thats becouse I only speculates, maybe something may looks different in these solution? Other way would be compiling second part of code on web server (there are available web autoit servers) maybe this way is possible? Tell me anything U know about this ideas and if its even possible to achieve.
      Thanks for ur any response, advice or thoughts
