64 or 32 ?

[madasraka]

I have a file in @scriptdir

File is 64bit executable (will not work on 32bit OS)

Is there a way for autoit to tell if this executable 64 or 32bit ?

By the way

Attached script returning all possible file properties is no help.

Get file property number.au3

Check this post where KaFu uses GetBinaryType

Of course.

Keyword is IMAGE_OPTIONAL_HEADER structure. Yo can do it manually or thru ImageNtHeader function (in that case IMAGE_NT_HEADERS structure plays, but that's just three different structures joined together IMAGE_NT_SIGNATURE+IMAGE_FILE_HEADER+IMAGE_OPTIONAL_HEADER).

edit:

But making it simple as the above post kills all the fun.

Oh cool

Thanks guys !

I now have to change few codes because if this discovery.

Ok i looked both at your links and search advices and found

Based on my level of autoit (programing) knowledge i could not put any of those two together.

1 of found examples involved executing an executable=BAD IDEA

Anoter example provided function involving DLL (i learned DLL files return different values in different OS 32 and 64 bit so this is no use too)

As for keyword "IMAGE_OPTIONAL_HEADER" ?

Well i git lost even more now

Maybe there is a simpler way to lets say:

Hex Read the file and finding traces of 64bit code ?

Then if that matches then $Var = "X64" ?

I dont know guys this seems way to complicated for me at this point.

Previously i would just rely on:

$var = '32'

If fileexist ('filename64.exe') = 1 Then assign ('var','64')

but this is to eazy and that file is not 100% guarantied to be there.

What possible thing could distract you? You were linked to the easiest possible solution.

What are you talking about? What links were you following?

Then i searched for IMAGE_OPTIONAL_HEADER

Kafu has written and posted the function for you.

If StringLeft(_GetBinaryType($yourfile),2) = "64" Then
;Yeah its 64bit
Else
;No its not
EndIf

Sorry i wasn't sure how to use it

Thanks
