Šiame straipsnyje aptarsime Python win32 procesą. Taip pat po vieną aptarsime jo metodus.
Iš esmės Win32 procesas yra Python metodas. Išplėstinės Win32 proceso kūrimo ir valdymo galimybės pasiekiamos per šį modulį. Sukūrimo metodas sukuria proceso objektus (konstruktorius). Galima naikinti, sustabdyti, atnaujinti ir nustatyti objektų procesų prioritetą naudojant papildomus metodus.
„Windows Management Instrumentation“ (WMI; anksčiau WBEM) ir „Windows“ tvarkyklės modelio WMI plėtiniai yra valdymo sistemos „Windows 2019/2016/2012/2008“ ir „Windows 10/7/XP“ (WDM) pagrindas.
„ActiveXperts Network Monitor“ siūlo galimybę kurti monitoriaus tikrinimo procedūras pagal WMI. „ActiveXperts“ surinko daugiau nei šimtą WMI pavyzdžių. Šie pavyzdžiai gali būti kaip atspirties taškas visiškai naujoms tikrinimo procedūroms, kurias sukuriate patys.
Šioje svetainėje yra daug WMI pavyzdžių.
„ActiveXperts Network Monitor“ serveriams stebėti naudoja Win32_Process WMI klasę.
„Windows“ operacinės sistemos įvykių seriją vaizduoja „Win32_Process WMI“ klasė. Seka, apimanti vieno ar kelių procesorių ar interpretatorių sąveiką, vykdomąjį kodą ir įvesties rinkinį, pvz., kliento programą, veikiančią Windows sistemoje, yra šios klasės palikuonis arba narys.
Dabar kyla klausimas kas yra Python win32?
Taigi Python win32 ir Win32 programų programavimo sąsajos (API) galimybes galima naudoti su Python, naudojant PyWin32 plėtinių biblioteką, skirtą Windows.
Paimkime nedidelę įvadą į win32api modulis.
„Win32api“ modulis siūlo įvairius papildomus procesų valdymo metodus. Tai suteikia galimybę atlikti daugelį įprastų veiksmų, reikalingų naujiems procesams pradėti, tačiau jie vis tiek nepasiūlo aukščiausio lygio žemo lygio valdymo.
Priešingai nei os.system funkcija, kuri buvo paaiškinta anksčiau, funkcija WinExec atlieka įvairius GUI programų pritaikymus. Pavyzdžiui, konsolė nenustatyta, o funkcija nelaukia, kol baigsis naujas procesas.
Funkcijai reikia šių dviejų įvesčių:
- Įsakymas vykdyti
- Arba pradinė programos lango būsena
Paimkime nedidelę įvadą į win32api.ShellExecute.
Be to, win32api modulis siūlo dar vieną naudingą funkciją pradedant naujus procesus. Skirtingai nuo atsitiktinių procesų pradžios, dokumentų atidarymas yra pagrindinis funkcijos „ShellExecute“ tikslas. Pavyzdžiui, galite nurodyti „ShellExecute“ „atidaryti MyDocument.doc“. „Windows“ pasirenka, kurį procesą paleisti jūsų vardu, kad būtų galima atidaryti.doc failus. Spustelėjus (arba dukart spustelėjus) a.doc failą, „Windows Explorer“ atlieka tą patį veiksmą.
Vykdoma programa vadinama procesu (apdorotu). Procesas nebūtinai turi būti toks, kurį vartotojas vykdo rankiniu būdu; Vietoj to tai gali būti sistemos procesas, kurį sukuria operacinė sistema. Bet kuri programa, kuri veikia operacinėje sistemoje, pirmiausia turi sugeneruoti atskirą procesą, kad galėtų pradėti veikti. Dauguma tipinio OS diegimo procesų yra foninės programos ir operacinės sistemos paslaugos, kurios naudojamos norint palaikyti gerą aparatinės įrangos, programinės įrangos ir operacinės sistemos veikimą.
Šiame įraše bus nagrinėjami keli alternatyvūs Python metodai, kaip gauti šiuo metu aktyvių Windows OS procesų sąrašą.
Norėdami gauti norimą rezultatą, pirmiausia apibūdinsime Python metodą. Tada išnagrinėsime komandą iš „Windows“ komandų procesoriaus, kad atliktume tą patį.

#import wmi module import wmi # Initializise the wmi constructor f = wmi.WMI() # Print the header print('Printing the pid Process name') # all the running processes for process in f.Win32_Process(): print(f'{process.ProcessId:<5} {process.name}') < pre> <p> <strong>Output:</strong> </p> <img src="//techcodeview.com/img/python-tutorial/88/python-win32-process.webp" alt="Python Win32 Process"> <br> <img src="//techcodeview.com/img/python-tutorial/88/python-win32-process-2.webp" alt="Python Win32 Process"> <p>The WMI() function of the wmi library is first initialized. This enables us to access its internal functions, such as WMI.Win32_Service, WMI.Win32_Process, and WMI.Win32_Printjob, each of which is intended to carry out a certain duty. To obtain a list of the system's active processes, we would use the WMI.Win32_Process function. After that, we iterated through all the running processes and placed them in the variable process by calling the function WMI.Win32_Process(). The corresponding attributes were then used to derive the process's ProcessID (pid) and ProcessName (name). To add padding to the output and properly align it, we used F-strings for the output.</p> <p>Now let's go through different methods of module Win32process.</p> <h3>1.

Gaukite proceso laiko statistiką naudodami jo rankenėlę. (100 nanosekundžių vienetų, skirtų UserTime ir KernelTime)
Parametrai
40. GetProcessIoCounters
win32process.GetProcessIoCounters
Sintaksė
dict = GetProcessIoCounters( hProcess )
Proceso įvesties / išvesties statistika grąžinama kaip žodynas, atitinkantis IO_COUNTERS struktūrą.
Parametrai
41. GetProcessWindowStation
win32process.GetProcessWindowStation
Sintaksė
GetProcessWindowStation()
Grąžina rankenėlę į lango stotį skambinimo procesui.
42. GetProcessWorkingSetSize
win32process.GetProcessWorkingSetSize
Sintaksė
int,int = GetProcessWorkingSetSize( hProcess )
Grąžinami proceso minimalūs ir didžiausi darbo rinkinių dydžiai.
Parametrai
43. SetProcessWorkingSetSize
win32process.SetProcessWorkingSetSize
Sintaksė
SetProcessWorkingSetSize( hProcess, MinimumWorkingSetSize, MaximumWorkingSetSize )
Nustato mažiausią ir didžiausią proceso darbinių rinkinių dydžius.
Parametrai
PASTABA: Norėdami visiškai pakeisti procedūrą, nustatykite tiek min, tiek max į -1.
44. GetProcessShutdownParameters
win32process.GetProcessShutdownParameters
Sintaksė
int,int = GetProcessShutdownParameters()
Atskleidžia dabartinį proceso nutraukimo lygį ir paleidiklius.
Diapazonas yra 000-0FF. langai rezervuoti, paskutinis, 200-2FF vidurinis, pirmasis, 300-3FF ir ketvirtas, 400-4FF langų rezervai.
45. SetProcessShutdownParameters
win32process.SetProcessShutdownParameters
Sintaksė
SetProcessShutdownParameters(Level, Flags)
Nustato proceso vėliavėles ir užbaigimo prioritetą.
Parametrai
Diapazonas yra 000-0FF. 100-1FF Paskutinis, 200-2FF Vidurinis, 300-3FF Pirmas, 400-4FF ir rezervuotas Windows lango rezervuotas.
46. GetGuiResources
win32process.GetGuiResources
Sintaksė
int = GetGuiResources(Process, Flags )
Pateikiamas GDI arba vartotojo objekto rankenėlių kiekis, kurį turi procesas.
Parametrai
47. IsWow64Process
win32process.IsWow64Process
Sintaksė
bool = IsWow64Process(Process)
Nurodo, ar WOW64 šiuo metu vykdo nurodytą procesą.
Parametrai
Pažiūrėkime jo grąžos vertę.
Grąžinama vertė yra False, jei operacinė sistema neteikia šios funkcijos (ty
Neįgyvendinta išimtis niekada nebus išmesta). Tačiau a
win32process.error išimtis paprastai pateikiama, jei funkcija yra prieinama
bet neveiksmingas.
Išvada
Šiame straipsnyje aptarėme Python win32 procesą. Be to, mes aptarėme skirtingus metodų tipus ir jų parametrus bei grąžinimo reikšmes po vieną.
