@🌈 Thinker 🌈 i invoke you

Thinker•2y ago

no idea what System.Management is

maria 🌟•2y ago

its built in on net but i dont now why i cant import it its like the wmic of windows

Thinker•2y ago

Looking at the docs for most of the types in that namespace, none of them list versions past .NET Framework 4.8.1 So in all likelihood it's not part of .NET Core / modern versions of .NET.

😭

Thinker•2y ago

What are you aiming to do exactly? There's probably some other ~~better~~ library for it.

 private static Process GetParentProcessId()
        {
            var currentProcess = Process.GetCurrentProcess();
            int parentProcessId = -1;
            string queryText = string.Format("select parentprocessid from win32_process where processid = {0}", currentProcess.Id);
            using (var searcher = new ManagementObjectSearcher(queryText))
            {
                foreach (var obj in searcher.Get())
                {
                    parentProcessId = Convert.ToInt32(obj["parentprocessid"]);
                    break;
                }
            }

                return  Process.GetProcessById(parentProcessId);
        }

 private static Process GetParentProcessId()
        {
            var currentProcess = Process.GetCurrentProcess();
            int parentProcessId = -1;
            string queryText = string.Format("select parentprocessid from win32_process where processid = {0}", currentProcess.Id);
            using (var searcher = new ManagementObjectSearcher(queryText))
            {
                foreach (var obj in searcher.Get())
                {
                    parentProcessId = Convert.ToInt32(obj["parentprocessid"]);
                    break;
                }
            }

                return  Process.GetProcessById(parentProcessId);
        }

... what is this why is there Convert.ToInt32 here why obj["parentprocessid"] why no string interpolation

DaVinki•2y ago

Just use NuGet to get System.Management

Thinker•2y ago

ah, that exists https://www.nuget.org/packages/System.Management/8.0.0-preview.2.23128.3

System.Management 8.0.0-preview.2.23128.3

Provides access to a rich set of management information and management events about the system, devices, and applications instrumented to the Windows Management Instrumentation (WMI) infrastructure. Commonly Used Types: System.Management.ManagementClass System.Management.ManagementObject System.Management.SelectQuery

            return  Process.GetProcessById(parentProcessId);
        }

better now? ummm

numbers

Thinker•2y ago

right, then you don't need the (int)

maria 🌟•2y ago

i dont really now but halp

Thinker•2y ago

Well, apparently it's not supported :/

maria 🌟•2y ago

WTF im on windows

maria 🌟•2y ago

Thinker•2y ago

ah yes, object I honestly have no idea, sorry

maria 🌟•2y ago

another thing that i prefere framework

Thinker•2y ago

it's fine to be wrong You should never ever use Framework for new projects. The only reason Framework is required here is because this library System.Management is very likely very very old.

maria 🌟•2y ago

bruh its just esayer on framework

Thinker•2y ago

what is easier? it's just this specific library

maria 🌟•2y ago

yes it just querys on windows components and a lot of things more

Thinker•2y ago

like what

maria 🌟•2y ago

one files not exe on cpp and the dll with the actual data of proyect

Thinker•2y ago

wdym?

maria 🌟•2y ago

? wdym??

Thinker•2y ago

just not sure what you meant by that

Aaron•2y ago

uint not int

maria 🌟•2y ago

GetProcessById accepts only int but whats difference in int and uint

Aaron•2y ago

why do you even want the parent process?

maria 🌟•2y ago

yes

Aaron•2y ago

(also you just just do (int)(uint))

maria 🌟•2y ago

i want to know if started from the explorer like if called from user or from automated application

Thinker•2y ago

int is signed (can be negative), uint is unsigned (cannot be negative) why do you need to know this?

maria 🌟•2y ago

thanks yes

Thinker•2y ago

that's not an answer

Aaron•2y ago

checking if called from explorer is not a good way to do that a user can use a command line too, after all

Matt•2y ago

"Programas Oscuros que cre en csharp".... are you creating something malicious?

Matt•2y ago

maria 🌟•2y ago

its just my funny folders names but believe what you want

SG97•2y ago

if that folder is actually in a OneDrive folder that gets synced back and forth, there's almost bound to be problems

arion•2y ago

@Gato have u tried pinvoke libraries instead of WMI Queries? WMI is usually slow, I've used this one before:

    internal static int GetParentProcessID_SnapshotIteration(int pid)
    {
        if (pid == 0) 
            return 0;

        using var hSnapshot = Kernel32.CreateToolhelp32Snapshot(Kernel32.CreateToolhelp32SnapshotFlags.TH32CS_SNAPPROCESS, 0);
        if (hSnapshot is { IsInvalid: true }) 
            return 0;
        
        var processes = Kernel32.Process32Enumerate(hSnapshot);
        return processes.First(p => p.th32ProcessID == pid).th32ParentProcessID;
    }

    internal static int GetParentProcessID_SnapshotIteration(int pid)
    {
        if (pid == 0) 
            return 0;

        using var hSnapshot = Kernel32.CreateToolhelp32Snapshot(Kernel32.CreateToolhelp32SnapshotFlags.TH32CS_SNAPPROCESS, 0);
        if (hSnapshot is { IsInvalid: true }) 
            return 0;
        
        var processes = Kernel32.Process32Enumerate(hSnapshot);
        return processes.First(p => p.th32ProcessID == pid).th32ParentProcessID;
    }

it uses the standard PInvoke lib, not vanara's sadge
