In questo articolo discuteremo del processo Python win32. E discuteremo anche i suoi metodi uno per uno.
Fondamentalmente, il processo Win32 è un metodo in Python. Le funzionalità estese di creazione e gestione dei processi Win32 sono accessibili tramite questo modulo. Il metodo Create crea oggetti di processo (il costruttore). È possibile terminare, sospendere, riprendere e impostare la priorità dei processi sugli oggetti utilizzando metodi aggiuntivi.
Strumentazione gestione Windows (WMI; in precedenza WBEM) e le estensioni WMI per il modello di driver Windows fungono da basi per la gestibilità in Windows 2019/2016/2012/2008 e Windows 10/7/XP (WDM).
La possibilità di creare procedure di controllo del monitor basate su WMI è offerta da ActiveXperts Network Monitor. Sono disponibili più di cento campioni WMI raccolti da ActiveXperts. Questi esempi potrebbero servire come punto di partenza per nuove routine di controllo che creerai autonomamente.
Molti esempi WMI sono disponibili su questo sito Web.
ActiveXperts Network Monitor utilizza la classe WMI Win32_Process per monitorare i server.
Una serie di eventi in un sistema operativo Windows è rappresentata dalla classe WMI Win32_Process. Una sequenza che coinvolge l'interazione di uno o più processori o interpreti, del codice eseguibile e un insieme di input, come un programma client in esecuzione su un sistema Windows, è un discendente o un membro di questa classe.
Ora sorge la domanda cos'è Python win32?
Pertanto le funzionalità API (Application Programming Interface) di Python win32 e Win32 possono essere utilizzate con Python utilizzando la libreria di estensioni PyWin32 per Windows.
Facciamo una piccola introduzione al Modulo win32api.
Il modulo win32api offre vari metodi aggiuntivi per il controllo dei processi. Questi ti danno la possibilità di eseguire molti dei soliti passaggi necessari per avviare nuovi processi, ma non riescono ancora a offrire il massimo livello di controllo di basso livello.
A differenza della funzione os.system spiegata in precedenza, la funzione WinExec offre diverse sistemazioni per i programmi GUI. Ad esempio, non viene stabilita alcuna console e la funzione non attende il completamento del nuovo processo.
La funzione richiede questi due input:
- L'ordine da eseguire
- In alternativa, lo stato iniziale della finestra dell'applicazione
Facciamo una piccola introduzione al win32api.ShellExecute.
Inoltre il modulo win32api offre un'altra caratteristica vantaggiosa per l'avvio di nuovi processi. A differenza dell'avvio di processi casuali, l'apertura di documenti è lo scopo principale della funzione ShellExecute. Ad esempio, puoi istruire ShellExecute ad 'aprire MyDocument.doc'. Windows sceglie quale processo avviare per tuo conto per aprire i file.doc. Il clic (o il doppio clic) su un file a.doc fa sì che Esplora risorse esegua la stessa azione.
Un programma in esecuzione viene definito processo (elaborato). Non è necessario che un processo venga eseguito manualmente dall'utente; potrebbe invece essere un processo di sistema generato dal sistema operativo. Qualsiasi programma eseguito su un sistema operativo deve prima generare un processo separato prima di poter iniziare a funzionare. La maggior parte dei processi in una tipica installazione del sistema operativo sono programmi in background e servizi del sistema operativo utilizzati per mantenere l'hardware, il software e il sistema operativo in buone condizioni.
Questo post esaminerà alcuni metodi Python alternativi per ottenere un elenco dei processi attualmente attivi di un sistema operativo Windows.
Per ottenere il risultato desiderato, descriveremo prima un metodo Python. Esamineremo quindi un comando dal processore dei comandi di Windows per ottenere la stessa cosa.

Esempio
#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.

Parametri
Vediamo il suo Valore di Ritorno.
Il valore restituito è False se il sistema operativo non fornisce questa funzione (ovvero,
non verrà mai generata un'eccezione NotImplemented). Tuttavia, a
