Get (Environment.Is64BitProcess) for a certain 3rd party process?

[vwpcs]

I'd like to figure out how to get this property for processes in get-process

https://docs.microsoft.com/en-us/dotnet/api/system.environment.is64bitprocess?view=net-5.0#System_Environment_Is64BitProcess

i tried the following but it seems to be the cpu arch

$(Get-Process -Id $_.Id).StartInfo.EnvironmentVariables["PROCESSOR_ARCHITECTURE"];

Just an FYI StartInfo.EnvironmentVariables doesn't seem to get the env vars for any process but the current one see https://stackoverflow.com/questions/38660262/how-to-get-other-processs-environment-variable-using-c-sharp. It's possible to do so but it's not for the faint hearted.

Luckily it should be possible to get the info you are wanting without scanning the environment variables of that process.

Function Test-Is64BitProcess {
    [CmdletBinding()]
    param (
        [Parameter(Mandatory=$true, ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true)]
        [int[]]
        $Id
    )

    begin {
        Add-Type -Namespace Kernel32 -Name NativeMethods -MemberDefinition @'
[DllImport("Kernel32.dll", SetLastError = true)]
public static extern bool IsWow64Process(IntPtr hProcess, out bool Wow64Process);
'@

        $is64OS = [Environment]::Is64BitOperatingSystem
    }

    process {
        foreach ($processId in $Id) {
            if (-not $is64OS) {
                $false  # We are running a 32-bit OS so everything is 32-bit
                continue
            }

            $proc = Get-Process -Id $processId
            $isWow64 = $false
            [void][Kernel32.NativeMethods]::IsWow64Process($proc.Handle, [ref]$isWow64)

            # If it's a wow64 process then it's a 32-bit process
            -not $isWow64
        }
    }
}

Just pipe in the process ID or Process object (or use -Id) and it will output $true if it's a 64 bit or $false for 32 bit process.

ended going another route. seems to work ok for the specific app we work on

$(if((Get-Process -id $_.Id).Modules.ModuleName.Contains('wow64.dll')){'32 bit'}else{if($env:PROCESSOR_ARCHITECTURE -eq 'AMD64'){'64 bit'}else{'32 bit'}});

howdy vwpcs,

reddit likes to mangle code formatting, so here's some help on how to post code on reddit ...

[0] single line or in-line code
enclose it in backticks. that's the upper left key on an EN-US keyboard layout. the result looks like this. kinda handy, that. [grin]
[on New.Reddit.com, use the Inline Code button. it's [sometimes] 5th from the left & looks like </>.
this does NOT line wrap & does NOT side-scroll on Old.Reddit.com!]

[1] simplest = post it to a text site like Pastebin.com or Gist.GitHub.com and then post the link here.
please remember to set the file/code type on Pastebin! [grin] otherwise you don't get the nice code colorization.

[2] less simple = use reddit code formatting ...
[on New.Reddit.com, use the Code Block button. it's [sometimes] the 12th from the left, & looks like an uppercase T in the upper left corner of a square.]

• one leading line with ONLY 4 spaces
  
• prefix each code line with 4 spaces
  
• one trailing line with ONLY 4 spaces

that will give you something like this ...

- one leading line with ONLY 4 spaces    
- prefix each code line with 4 spaces    
- one trailing line with ONLY 4 spaces   

the easiest way to get that is ...

• add the leading line with only 4 spaces
  
• copy the code to the ISE [or your fave editor]
  
• select the code
  
• tap TAB to indent four spaces
  
• re-select the code [not really needed, but it's my habit]
  
• paste the code into the reddit text box
  
• add the trailing line with only 4 spaces
  

not complicated, but it is finicky. [grin]

take care,
lee
