V tomto článku budeme diskutovať o procese Python win32. A tiež budeme diskutovať o jeho metódach jeden po druhom.
Proces Win32 je v podstate metóda v Pythone. Prostredníctvom tohto modulu sú dostupné rozšírené možnosti tvorby a správy procesov Win32. Metóda Create vytvára procesné objekty (konštruktor). Je možné zabiť, pozastaviť, obnoviť a nastaviť prioritu procesov na objektoch pomocou ďalších metód.
Rozšírenia Windows Management Instrumentation (WMI; predtým WBEM) a WMI pre model ovládačov Windows slúžia ako základy spravovateľnosti v systémoch Windows 2019/2016/2012/2008 a Windows 10/7/XP (WDM).
Schopnosť vytvárať procedúry kontroly monitora založené na WMI ponúka ActiveXperts Network Monitor. ActiveXperts zhromaždil viac ako sto vzoriek WMI. Tieto príklady môžu slúžiť ako východiskový bod pre úplne nové kontrolné postupy, ktoré si vytvoríte sami.
Na tejto webovej lokalite je k dispozícii veľa ukážok WMI.
ActiveXperts Network Monitor používa triedu WMI Win32_Process na monitorovanie vašich serverov.
Séria udalostí v operačnom systéme Windows je reprezentovaná triedou WMI Win32_Process. Sekvencia, ktorá zahŕňa interakciu jedného alebo viacerých procesorov alebo interpretov, niektorého spustiteľného kódu a množiny vstupov, ako je napríklad klientsky program bežiaci na systéme Windows, je potomkom alebo členom tejto triedy.
Teraz vyvstáva otázka čo je Python win32?
Takže možnosti rozhrania Python win32 a Win32 aplikačného programovacieho rozhrania (API) možno použiť s Pythonom pomocou knižnice rozšírení PyWin32 pre Windows.
Urobme si malý úvod do modul win32api.
Modul win32api ponúka rôzne extra metódy riadenia procesov. Tie vám dávajú možnosť vykonať mnoho zvyčajných krokov potrebných na spustenie nových procesov, no stále nedosahujú najvyššiu úroveň nízkoúrovňového riadenia.
Na rozdiel od funkcie os.system, ktorá bola vysvetlená vyššie, funkcia WinExec vytvára rôzne prispôsobenia pre programy GUI. Napríklad nie je vytvorená žiadna konzola a funkcia nečaká, kým sa dokončí nový proces.
Funkcia vyžaduje tieto dva vstupy:
- Príkaz vykonať
- Prípadne počiatočný stav okna aplikácie
Urobme si malý úvod do win32api.ShellExecute.
Okrem toho modul win32api ponúka ďalšiu výhodnú funkciu pre spúšťanie nových procesov. Na rozdiel od spúšťania náhodných procesov je hlavným účelom funkcie ShellExecute otváranie dokumentov. ShellExecute môžete dať pokyn, aby napríklad „otvoril súbor MyDocument.doc“. Systém Windows vyberie, ktorý proces sa spustí vo vašom mene, aby bolo možné otvoriť súbory open.doc. Kliknutie (alebo dvojité kliknutie) na súbor a.doc spôsobí, že Windows Explorer vykoná rovnakú akciu.
Program, ktorý je spustený, sa označuje ako proces (spracovaný). Proces nemusí byť ten, ktorý používateľ spúšťa manuálne; namiesto toho to môže byť systémový proces, ktorý operačný systém vytvorí. Každý program, ktorý beží na operačnom systéme, musí najskôr vygenerovať samostatný proces, aby mohol začať fungovať. Väčšina procesov v typickej inštalácii OS sú programy na pozadí a služby operačného systému, ktoré sa používajú na udržanie hardvéru, softvéru a operačného systému v dobrom prevádzkovom stave.
Tento príspevok sa pozrie na niekoľko alternatívnych metód Pythonu na získanie zoznamu aktuálne aktívnych procesov operačného systému Windows.
Aby sme dosiahli požadovaný výsledok, najprv opíšeme metódu Pythonu. Potom preskúmame príkaz z príkazového procesora Windows, aby sme dosiahli to isté.

Príklad
#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.

I/O štatistiky pre proces sa vrátia ako slovník zodpovedajúci štruktúre IO_COUNTERS.
Parametre
41. GetProcessWindowStation
win32process.GetProcessWindowStation
Syntax
GetProcessWindowStation()

negácia diskrétna matematika
42. GetProcessWorkingSetSize
win32process.GetProcessWorkingSetSize
Syntax
int,int = GetProcessWorkingSetSize( hProcess )
Vrátia sa minimálna a maximálna veľkosť pracovnej sady procesu.
Parametre
43. SetProcessWorkingSetSize
win32process.SetProcessWorkingSetSize
Syntax
SetProcessWorkingSetSize( hProcess, MinimumWorkingSetSize, MaximumWorkingSetSize )
Nastavuje minimálnu a maximálnu veľkosť pracovnej sady pre proces.
Parametre
POZNÁMKA: Ak chcete úplne zmeniť postup, nastavte minimálnu aj maximálnu hodnotu na -1.
44. GetProcessShutdownParameters
win32process.GetProcessShutdownParameters
Syntax
int,int = GetProcessShutdownParameters()
Odhaľuje aktuálnu úroveň ukončenia procesu a spúšťa.
Rozsah je 000-0FF. okná vyhradené, posledné, 200-2FF Stredné, prvé, 300-3FF a štvrté, 400-4FF rezervy Windows.
45. SetProcessShutdownParameters
win32process.SetProcessShutdownParameters
Syntax
matematické metódy v Jave
SetProcessShutdownParameters(Level, Flags)
Nastavuje príznaky procesu a prioritu ukončenia.
Parametre
Rozsah je 000-0FF. 100-1FF Posledný, 200-2FF Stred, 300-3FF Prvý, 400-4FF a rezervované oknom Windows rezervované.
46. GetGuiResources
win32process.GetGuiResources
Syntax
int = GetGuiResources(Process, Flags )
Poskytuje množstvo GDI alebo používateľských objektov, ktoré proces drží.
Parametre
47. IsWow64Process
win32process.IsWow64Process
Syntax
bool = IsWow64Process(Process)
Identifikuje, či WOW64 momentálne beží zadaný proces.
Parametre
Pozrime sa na jeho návratovú hodnotu.
Návratová hodnota je False, ak operačný systém túto funkciu neposkytuje (napr.
výnimka NotImplemented nebude nikdy vyvolaná). Avšak a
win32process.error výnimka z tohto je normálne vyvolaná, ak je funkcia dostupná
ale neúčinné.
Záver
V tomto článku sme diskutovali o procese Python win32. A tiež sme diskutovali o rôznych typoch metód a ich parametroch a návratových hodnotách jeden po druhom.
