app = Application(backend="uia").start("program.exe")
I am using pywinauto to do some tasks indefinitely. However, occasionally, I need to restart the script for some external reasons. When this happens, I would like to keep the created applications open. How can I do this? I noticed if the python script errors out, the applications will stay open. But if I exit the script manually, the windows will close. So there must be some way to accomplish this.
I think pywinauto's Application.start cannot do the work. You can try:
pid = os.spawnl(os.P_NOWAIT, "program.exe")
app = Application().connect(process=pid)
os.spawnl is considered deprecated. Use subprocess module.
Combining the answer in Run a program from python, and have it continue to run after the script is killed and pywinauto official doc, you can do this:
subprocess.Popen(
['your_program', 'with args'],
# These will make sure the desktop program will alive even when shell session terminates.
creationflags=subprocess.DETACHED_PROCESS | subprocess.CREATE_NEW_PROCESS_GROUP, shell=True
)
desktop = Desktop(backend="uia")
main_win = desktop.window(title="program's window title", control_type="Window")
Why not use system command:
#Use multiple thread to avoid block of system function
import _thread as qd
import os
qd.start_new_thread(os.system,('notepad',))
from pywinauto import Application
#connect pywinauto with application via title regular expression
win=Application(backend='uia').connect(title_re='.*Notepad.*')
Then you use pywinauto to connect application via title?
