I am currently working on a program that will back up my Skype and iTunes data. It works fine with my iTunes data, however, when I try to backup files from Skype I get loads of errors. These are caused from the program still being open.
I thought it would be a fun little project to try and find out how to force quit a program (and then re-open).
I have successfully learned how to OPEN Skype (with a simple statement,
import os
os.startfile(path) #this opens programs. I need to close.
So I think to get my program to work, all I would need to do is close skype, run the backup process, then re-open it.
When I tried searching my question, I was only finding answers to close PYTHON scripts. I need to close something that is running in Windows.
I have found the answer.
import os
os.system("taskkill /im skype.exe") #/im means "ImageName"
taskkill is a command-line reference.
"Ends one or more tasks or processes. Processes can be killed by process ID or image name"

Thank you #furas for leading me to the page with the answer. I'm surprised I missed it, I tried searching for a while.

I am making simple program to manage other programs. I can open scripts using
os.startfile(self.path)
But I anyways can't close my program. I tried many ways, but still can't do it.
I even tried `
subprocess.call("TASKKILL /F /IM firefox.exe", shell=True)
` but it closes only exe files, i also need to close py files
For example, i have program named 'notion.exe' and i can open it using
os.startfile('notion.exe')
Now, i want to close it using script 'handler.py', but i didn't find os method that closes file.
Can anyone tell me which library may I use to close 'notion.exe'?
I am trying to run a python script via cmd prompt on my work PC (Windows 7, Python 2.7). The script requires filepaths from different drives on my PC. I am correctly pulling all necessary filepaths and I press Enter to run the script but the script just hangs. The only thing that shows is a blinking underscore. I try to click the X to close the prompt but nothing happens.
I am not able to Ctrl+C out of the program either. I open up Task Manager and I am not able to End Task (nothing happens) or End Process (cmd.exe doesn't even show up in this tab). I also tried Start-->Run-->taskkill /im cmd.exe but nothing happens. The rest of my team has no problem with Python 2.7. The only way to get out of the frozen cmd is to hold down the power button. I do not want to have to keep going through this process especially since this is during work. I'm hoping someone will be able to help me out:
Any idea what's wrong with the version of Python I am using?
How am I able to kill cmd.exe so that I can continue normal work functions without having to hold down the power button and waiting 5-10 minutes to reboot my PC?
The filepaths I was pulling files from were through ClearCase directories. It turned out that I simply had to reinstall ClearCase. There must have been some configuration issue that was causing the cmd to hang and thus forcing a hard reboot. It's good to point out that I am no longer experiencing this problem and that nothing was wrong with the python scripts.
Basically it's all in the title, when I run the code from a console (on Windows) the child process runs without opening another console, but when I run the code from the cx_freeze'd app another console opens.
I found this old thread where was suggested to use FreeConsole(), it will flash the console on screen for a blink but I can eventually live with it, unfortunately if i understood correctly it should be called from the child process.
http://twistedmatrix.com/pipermail/twisted-python/2007-February/014738.html
I also found this ticket (7yo) on a re-factoring of the whole spawnProcess on windows but apparently it never happened:
http://twistedmatrix.com/trac/ticket/2415
I have no control over the code of the child process, so doing something there is unfortunately not an option, but even if I did the process I'm spawning it's a console app and I believe FreeConsole() could not be called there or the process will terminate.
This is possibly a bug in Twisted, but possibly a bug in cx_Freeze.
What happens when you run the code from the GUI with Python, but without cx_Freeze involved? You should be able to test this if you have Python installed by simply putting your code into a .pyw file and double-clicking on it in Explorer.
If this still pops up a console window when you run your subprocess, then this is totally a bug in Twisted and you should file it as such. Eric's answer in that mailing list message is wrong; if you want to spawn processes with spawnProcess they definitely shouldn't be popping up random console windows.
If the click-on-a-.pyw launching method doesn't cause a console window to pop up, then it's probably something about the way cx_Freeze has constructed your executable and you might want to look at it.
On UNIX, we have a platform-specific usePTY, so it makes sense that we could expand spawnProcess with a platform-specific useConsole that would do something analogous for Windows. This later message in the thread suggests an implementation strategy, so please file a ticket. The let's-redo-everything ticket is too ambitious to fix this one issue.
I wrote a small multiprocessing application and then wrote a PyQt front end for it. When I run the script by calling it from the command line with Python (or by calling run from the Spyder IDE), it runs exactly as I would expect and works nicely.
But if I try to use Py2Exe to make an executable to give it to a friend, it starts behaving oddly. When the users hits the botton that really starts the process and invokes the multithreading portion, it spawns multiple Qt windows that look like the original. It then essentially locks up. Closing one of the new windows that it spawns causes it to reopen that window. Attempting to close the original generates a message that it is not responding.
I would appreciate any help or suggestions about where to look.
I'm not positive about this without looking at your code, but there are some extra considerations when using Py2Exe with multithreading.
Take a look at this link and maybe it has something to do with your problem.
Someone has a similar sounding issue here
I would like to write a python script that will finally be converted to .exe (with pyinstaller lets say) and added to windows startup applications list. This program (once launched) should 'monitor' user and wait until user will start a specified program (say program1.exe) and then my python program should launch another specified program (program2.exe).
I know that there is something like subprocess to launch another program from python script but I was not able to make it work so far ;/ And as it comes to this part where I need to monitor if user does start specified program I have no idea haw to bite on this. I don't expect a complete solution (although it would be very nice to find such ;p) but any guides or clues would be very helpfull.
For the monitoring whether or not the user has launched the program, I would use psutil: https://pypi.python.org/pypi/psutil
and for launching another program from a python script, I would use subprocess.
To launch something with subprocess you can do something like this:
PATH_TO_MY_EXTERNAL_PROGRAM = r"C:\ProgramFiles\MyProgram\MyProgramLauncher.exe"
subprocess.call([PATH_TO_MY_EXTERNAL_PROGRAM])
If it is as simple as calling an exe though, you could just use:
PATH_TO_MY_EXTERNAL_PROGRAM = r"C:\ProgramFiles\MyProgram\MyProgramLauncher.exe"
os.system(PATH_TO_MY_EXTERNAL_PROGRAM)
Hope this helps.
