Usage Examples

Example 1: Read console output

examples/read_console_output.py

import uuid
import time
import subprocess

from win32fastutils import consoleutils

CMD = "C:\\Windows\\System32\\cmd.exe"

msg1 = str(uuid.uuid4())
proc = subprocess.Popen([CMD, "/C", "echo", msg1, "&&", "timeout", "2"], creationflags=subprocess.CREATE_NEW_CONSOLE)
time.sleep(1)
result = ""
with consoleutils.ResetableAttachConsole(proc.pid):
    result = consoleutils.ReadConsoleOutputText()
print(result)

result output

C:\workspace\win32fastutils>python examples\read_console_output.py
8a3d81ac-9f59-4066-8206-86cee8101f8c <Note: a lot of space here....>

等待 1 秒，按一个键继续 ...

Example 2: Press ENTER to end the timeout waiting

examples/press_enter_to_end_time_timeout_waiting.py

import uuid
import time
import datetime
import subprocess

from win32fastutils import guiutils

CMD = "C:\\Windows\\System32\\cmd.exe"

print("start", datetime.datetime.now())
msg1 = str(uuid.uuid4())
proc = subprocess.Popen([CMD, "/C", "echo", msg1, "&&", "timeout", "20"], creationflags=subprocess.CREATE_NEW_CONSOLE) # wait for 20 seconds
time.sleep(1)
hwnds = guiutils.GetHwndsByProcessIds(proc.pid)

guiutils.PostMessage(hwnds[0], "\n") # press ENTER to end the timeout waiting
proc.wait()
print("end  ", datetime.datetime.now())

result output

C:\workspace\win32fastutils>python examples\press_enter_to_end_the_timeout_waiting.py
start 2022-02-17 17:01:15.115822
end   2022-02-17 17:01:16.210102

Example 3: Using 32bit-version-python in 64bit-version-windows, we can NOT access files under folder C:\Windows\System32, How to fix the problem?

import os
from win32fastutils import py32fix

SSH = "C:\\Windows\\System32\\OpenSSH\\ssh.exe"

print("Access directly result:", os.path.exists(SSH))

with py32fix.DisableFileSystemRedirection():
    print("Access in fixed scope: ", os.path.exists(SSH))

result output

C:\workspace\win32fastutils>python examples\32bit_python_access_application_under_system.py
Access directly result: False
Access in fixed scope:  True
