Wmi Queries Re: Platform / Detection

plastix · April 8, 2006

Hi all.

Have customised a system information script that uses WMI do collect data (and added code generated from 'Scriptomatic' - nice one SvenP). I know that AutoIt has some nice macro's that supply some useful system information (mainly by reading registry info). It occurred to me that a script i am writing at the moment is likely to be run on a number of WinNT / 95 / 98 (with IE4) systems - and as such I believe won't have WMI... but maybe i'm getting confused with WSH

will the script throw an error, or just return "null" strings etc ? (got no systems earlier than winXP to check)
Is there an alternative to WMI for in-depth system info ?
any code examples to detect WMI (maybe an idea for a future macro ie @WMI returns true if present etc ?

TIA

Before I answer, what kind of information are you trying to get from wmi?

plastix · April 8, 2006

hi forger. thanks. specifically, i am getting the following info:

Quote
CIM_Processor: Name, MaxClockSpeed, Description, SystemName
Win32_OperatingSystem: Caption, BuildNumber, ServicePackMajorVersion, ServicePackMinorVersion, FreePhysicalMemory, FreeVirtualMemory
Win32_ComputerSystem: TotalPhysicalMemory, Domain, Workgroup
Win32_VideoController: Description
Win32_SoundDevice: Description
...and use Scripting.FileSystemObject.Drives for drive info.

Some items are non-essential. What would be useful to know is whether the script would fail or not if WMI is not available. If there are means of obtaining the information without WMI calls, then I could set up a check for Win98/NT etc, and collect the information another way (if i can't check to see if WMI is available).

All help greatfully received. TIA for your time

Windows management instrumentation requires the wmicore: http://www.microsoft.com/downloads/details...5B-FBF236E0E875

It is pre-installed in Windows Me, Windows 2000, Windows XP and Windows Server 2003:

http://www.microsoft.com/technet/scriptcen...wmifaq.mspx#EJC

Yes, logically the scripts fail if WMI is not present. I believe you can check if wmi is supported with one of the following:

a. ~~the output of "wmic" command in a dos.~~ (edit: I just found out that it's not used in win9x or nt, only remotely this can be used )

I think if wmi is not installed the command is not recognized, and you get something like this:

'wmic' is not recognized as an internal or external command,

operable program or batch file.

You can use StdoutRead (read the help file)

b. by simply checking if the windows version is one of the above mentioned (but that doesn't mean they didn't update, ~~so I'd go with the first one~~)

c. I found out the installation directory of wmicore:

$wmicoredir = @SystemDir & "\wbem"

I also found a helpful link: http://www.wtcs.org/snmp4tpc/wmi.htm#Insta...%20Windows%209x

d. Logically in Windows NT versions (NT,XP,2000,2003) wmi runs as a service, whereas in Windows 95/98 it should show up in a value under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices key.

Now you should be able to identify through checking if the service or the value under that key exists for each windows version (I hope)

How to get a lot of info through wmi scripting? Windows XP Pro has a nice command: systeminfo

Unfortunately it's not in windows xp home edition or any other windows from what I know (maybe windows 2003 has it).

Someone could help you furthermore with wmi scripting if you don't know how to call the objects you need, because I haven't used it a lot. Some are supported by autoit already as macros and some can be found in the registry, but I've never dug that deep to be honest

For example, (windows xp pro sp2 here) under: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum you may find a lot of devices, you could simply extract the info from there:

$regvalue = RegRead ( "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_10DE&DEV_008A&SUBSYS_00801462&REV_A1\3&13c0b0c5&0&30, "DeviceDesc")
;This the PCI for my sound card: "DeviceDesc"="Realtek AC'97 Audio"
MsgBox("","regstring","I have this sound card: " & $regvalue)

Note: A lot of stuff varies under Enum, but it still is a possible workaround instead of wmi. Maybe someone else can suggest different and better registry places here

Cheers forger. Actually, i have the WMI calls working nicely... I was actually thinking ahead to what would happen on systems without WMI. I guess i could check to see that IE >=5 installed (via registry HKLM\Microsoft\Windows\CurrentVersion\App Path\IEXPLORE.EXE - then FileGetVersion() on "Path" from registry)... that way WMI should be installed also. My thoughts are more ot do with trapping / modifying script running if WMI not present - and maybe providing some of the info via other means...

Thanks again

forger · April 9, 2006

I just edited my post, I found some statements that were not true hehe

but the "d." part should cover your question I guess.

Or this would be a quick alternative:

$wmimainfile = @SystemDir & "\wbem\winmgmt.exe"
If FileExists($wmimainfile) Then
    MsgBox("","found","wmi exists")
EndIf

forger · April 9, 2006

I *think* I just found a way to extract a lot of info without using wmi. From what I understand, you can use it with windows 9x as well. Thanks for making me dig this up

For example, go to start > run and type this:

start msinfo32 /categories +ComponentsMultimediaSound+ComponentsDisplay /report c:\report.txt

You can see the categories available from which you can choose to +(add) or -(remove) by:

start msinfo32 /showcategories

Here's my output:

madness

Nice work forger.

MsInfo32 should work on all platforms i guess... limiting to a few switches should speed it up and miss out the drivers etc etc... ~~the only pain is the output is a little tricky to parse... maybe can get all the info out "easily"... will experiment.~~

WMI is quicker +, so I think (if i can parse this output) i'll use that if it is available - ~~otherwise i'll fiddle with this. Nice one again.~~ Looks very promising.

OK. Here's a "dirty" and kinda neat trick with this baby. Output is (on my system) in Unicode. The text uses TAB delimiter... so an idea is to convert the text to ANSI, then read it in Line by Line and replace first TAB in each with "=". If you look closely, that will convert the file into something that looks like a standard INI file - and then, nicely, you can use IniRead to get the info out

$uniFile = "report.txt"
$ansiFile = "report_ansi.txt"
RunWait(@ComSpec & ' /c Type "' & $uniFile & '" > "' & $ansiFile & '"',"",@SW_HIDE)
MsgBox(0,"Converted To ANSI",":)")

$filehandle = FileOpen("report_ansi.txt",0)
$output = FileOpen("report.ini",2)
While 1
    $line = FileReadLine($filehandle)
    If @error = -1 Then ExitLoop
$parsed = StringReplace($line,Chr(9),"=",1)
FileWriteLine($output,$parsed)
Wend
FileClose($filehandle)
FileClose($output)

$pc = IniRead("report.ini","System Summary","Processor","Unknown")
msgbox(0,"Info",$pc)

Could do with some refining, but its a start

Well, you can always do:

start /wait msinfo32 ...

That will wait for the msinfo to end. It takes a couple of seconds on my machine and RunWait with start /wait would work perfectly pausing the script!

How about this:

    If $_Outputfile = "" Then
        $_Outputfile = "_report.ini"
    EndIf
    Local $_Outputfiletmp = StringTrimRight($_Outputfile, 4) & '_tmp.ini', $_Readline, $_check
    FileDelete($_Outputfile)
    FileDelete($_Outputfiletmp)
    RunWait(@ComSpec & " /c start /wait msinfo32 /categories " & $_Categories & " /report " & $_Outputfile, "", @SW_HIDE)
    If @OSTYPE = "WIN32_NT" Then
        RunWait(@ComSpec & ' /c Type "' & $_Outputfile & '" >> "' & $_Outputfiletmp & '"', "", @SW_HIDE)
        FileMove($_Outputfiletmp, $_Outputfile, 1)
    EndIf
    _ReplaceStringInFile ($_Outputfile, @TAB, "=")
    _ReplaceStringInFile ($_Outputfile, "Item=Value=", "")
    $i = 1
    While $i <= _FileCountLines($_Outputfile)
        $_Readline = FileReadLine($_Outputfile, $i)
        If StringLeft($_Readline, 37) = "System Information report written at:" Then
            _FileWriteToLine ($_Outputfile, $i, "[Report]" & @CRLF & "Report Time=" & StringTrimLeft($_Readline, 38), 1)
            $i = $i - 2;Resets the line number
        ElseIf StringLeft($_Readline, 12) = "System Name:" Then
            _FileWriteToLine ($_Outputfile, $i, "", 1);Deletes the line
            $i = $i - 1;Resets the line number
        ElseIf StringRight($_Readline, 1) = "=" Then
            _FileWriteToLine ($_Outputfile, $i, StringTrimRight($_Readline, 1), 1)
            $i = $i - 1
        ElseIf $_Readline = "" Then
            _FileWriteToLine ($_Outputfile, $i, "", 1);Deletes the line
        EndIf
        $i = $i + 1
    WEnd
    Return $_Outputfile
EndFunc

$Outputfile = _GetInfoFromMSInfo32("","+ComponentsMultimediaSound+ComponentsDisplay")

But the problem is which categories are available in windows 9x/me

nice

Confuzzled · April 9, 2006

Um, Sadly I think you will find that not all those switches are present for older versions of MSINFO/MSINFO32.

A lot of the info is already available from existing AutoIT functions and you should be able to get most of the rest directly from the registry.

The forums have a lot of ideas as these are not unique requests.

forger · April 9, 2006

Not all, but they ought to have the same structure.

I'm looking to see the differences, I hope I'll be able to.

By the way, I've already mentioned the registry and AutoIt support for most of these stuff at this post

Edit: and it's not bad to have an alternative

Edited April 9, 2006 by forger

plastix · April 9, 2006

OK. fiddled on a few platforms over this weekend.

vanilla Win95OSR2 - no dice (No msinfo/msinfo32)

vanilla Win98SE - msinfo32 present. command line call opened msinfo32 on-screen, but the report switch didn't spool output to file. may have a different syntax, but likely not supported

vanilla WinNT4 - pending...

...all in all, not that favourable.

forger · April 9, 2006

Edit: MSINFO32 for windows 95 comes bundled with few multimedia products. They'd have to get it, I guess bill gates didn't think that far back at that time

Edit 2: Can you export a .nfo or .txt and upload & attach it here from windows 98? I'd like to see the differences for msinfo32 between xp and 98

Oh well, worth a shot

You might consider checking if WINMSD command is available:

WINMSD

Microsoft Windows diagnostics
Reports: Memory use, Services, Devices, IRQ's Ports, Environment variables,
Network (rights, transport, stats), Hardware including Display adapter.

Syntax
      WINMSD [\\computername] options

Options:
       /a          All details
       /s          Summary details only
       /f          Send output to a file <computername.txt> in the current directory 
       /p          Send output to a printer

      WINMSD with no switches will open the GUI with details of the computer you are logged into. 

When a remote computername is specified then less info will be reported
e.g. Diskspace and Memory won't be listed

Hot keys within the GUI:

SHIFT - F2 copies the current tab to the clipboard,
F2 copies a summary of the current tab to the clipboard

or WINMSDP (if you have the resource kit):

Windows NT diagnostics II Reports: Memory use, Services, Devices, IRQ's Ports, Environment variables, Network (rights, transport, stats), Hardware including Display adapter.

Syntax
      WINMSDP option

Key (only one option can be used)

  /a  : ALL prints everything

  /e  : environment
  /d  : drives
  /i  : interrupt resources
  /m  : memory
  /n  : network
  /o  : OS version
  /p  : port resources
  /r  : drivers
  /s  : services
  /u  : DMA resources
  /w  : hardware
  /y  : memory resources
 

The output is very similar to WINMSD if a little more detailed.
The output will appear in a text file called msdrpt.TXT
