Topic: Test for 32 vs 64 bit

[GDF]

How would I test within a lisp routine to check for 32 vs 64 bit operaring system?

I need to load different arx files based on the test above.

Here are the two files I need to check for:
DOSLib17.arx
DOSLib17x64.arx

Code: [Select]

(defun ARCH:DOSLIBLOADER  ()
  (cond ((and (>= (distof (substr (getvar "acadver") 1 4)) 15.0)
              (< (distof (substr (getvar "acadver") 1 4)) 16.0))
         (if (not (member "doslib2k.arx" (arx)))
           (arxload (findfile (strcat ARCH#SUPF "V_15\\doslib2k.arx")))))

        ((and (>= (distof (substr (getvar "acadver") 1 4)) 16.0)
              (< (distof (substr (getvar "acadver") 1 4)) 17.0))       
         (if (not (member "doslib2004.arx" (arx)))
           (arxload (findfile (strcat ARCH#SUPF "V_16\\doslib2004.arx")))))

        ((and (>= (distof (substr (getvar "acadver") 1 4)) 17.0)
              (< (distof (substr (getvar "acadver") 1 4)) 18.0))       
         (if (not (member "DOSLib17.arx" (arx)))
           (arxload (findfile (strcat ARCH#SUPF "V_17\\DOSLib17.arx")))))

        ((and (>= (distof (substr (getvar "acadver") 1 4)) 18.0)
              (< (distof (substr (getvar "acadver") 1 4)) 19.0))       
         (if (not (member "DOSLib17.arx" (arx)))
           (arxload (findfile (strcat ARCH#SUPF "V_18\\DOSLib17.arx")))))
  )
  (princ))

This isn't necessarily a foolproof method, but you could check for the existance of C:\Program Files(x86) ... on all 64 bit systems, 32bit programs are installed in the C:\Program Files(x36) folder, while 64 bit programs are installed in C:\Program Files

Gary,

Not of much, help I know... but

If I remember right, the guys from OpenDCL, have an autolisp function for this....

[VovKa]

running 32bit
so i can not say for sure but you may try any of these

Code: [Select]

(vl-registry-read "HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows NT\\CurrentVersion" "ProductName")
(getenv "PROCESSOR_ARCHITECTURE")
(getenv "OS")


[CAB]

Would this not work? [Not Tested]

Code: [Select]

        ((and (>= (distof (substr (getvar "acadver") 1 4)) 18.0)
              (< (distof (substr (getvar "acadver") 1 4)) 19.0))       
         (if (not (or (member "DOSLib17.arx" (arx))(member "DOSLib17x64.arx" (arx))))
           (or (arxload (findfile (strcat ARCH#SUPF "V_18\\DOSLib17x64.arx")))
                (arxload (findfile (strcat ARCH#SUPF "V_18\\DOSLib17.arx"))))))
<edit>
Now that I think about the situation, you may have the file present but not the resource.

VovKa, That is a good push in the right direction ... this should work flawlessly ... returns 32 for 32 bit and 64 for 64 bit

Code: [Select]

(if (= (getenv "PROCESSOR_ARCHITEW6432") nil)
    32
    64
)

Maybe this will provide you the information needed:

http://through-the-interface.typepad.com/through_the_interface/2007/04/loading_the_rig.html

At the bottom you will find a modified arxload function to test between 32 or 64 bit.

Thanks Alan, this worked.

Thanks for the link, I will have to dig into it.

Gary, all versions of Windows create environment variables that determine what kind of processor architecture is running. If it is a 64 bit process you will always find PROCESSOR_ARCHITEW6432 in the environment variables, however, it will be nonexistant on 32 bit operating systems, therefore you can readily tell if the OS is running a 64 bit process or 32 bit. All windows will have the environment variable PROCESSOR_ARCHITECTURE, but you would need to verify the value against a set of unknowns.

The mere existance of PROCESSOR_ARCHITEW6432 assures you that you have a 64 bit OS running so the result would be effective.

cool Keith™, i'll save it in my "in case of" notes

Thanks. I am playing around with and testing autocad 2009 on windows xp 64 bit on a backup machine.

So far I think autocad 09 is ___ well lets just say, I think I'll keep on 2008 for a while longer.

Do you have the 64 bit version of AutoCAD running? If not then I am not sure you can run the 64bit arx modules.

Yes I have 2009 running with all of my customization "arch program" on a 64 bit window xp machine. The DOSLib17x64.arx file loads ok...used CAB's code.
I'm looking for an acetutil.arx 64 bit version.

Everything seems to be running ok, just a very minor glitches.

My first impression is that it takes longer to open drawing files, and I don't like autocads new menu interface.

My goal is to update my "arch program" custom routines to be able to run either a 32 or 64 bit operating system.

Expresstools for 64bit ... hmmm ... might be hard to come by ... will the 32bit modules not load?
