问题 Is there a difference between os.execl() and os.execv() in python? I was using os.execl(python, python, *sys.argv) to restart my script (from here). But it seems to start from where the previous script left. I want the script to start from the beginning when it restarts. Will this os.execv(__file__,sys.argv) do the job? command and idea from here. I couldn't find difference between them from the python help/documentation. Is there a way do clean restart? For a little more background on what I

How to ask for batch file user input with a timeout

阅读更多关于 How to ask for batch file user input with a timeout

So I am trying to add a timer to one of my if statements under a set command but I'm not sure what the command would be. The script will launch and wait thirty minutes before it reboots the PC or wait for a users input to input it at that time or cancel it. So I have my two if statements for the "restart now" and "cancel" set but now I need an if statement to have it count down from thirty minutes before it executes my restart command. Also if anyone knows how to add a visual timer on there showing how much time is left that would be a plus. Thanks guys!!! @Echo off :START set /p answer=PC

I am having a confusion in restarting an activity.. I have two function that works well for the same task. Please guide me which is best and why? public void restart() { Intent intent = getIntent(); overridePendingTransition(0, 0); intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION); finish(); overridePendingTransition(R.anim.fade,R.anim.fade); startActivity(intent); } or public void restart() { onCreate(); } Thanks In advance? I think this is a cleaner way for your requirement. Intent intent = getIntent(); overridePendingTransition(0, 0); intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);

Monitor Process in Python?

阅读更多关于 Monitor Process in Python?

I think this is a pretty basic question, but here it is anyway. I need to write a python script that checks to make sure a process, say notepad.exe, is running. If the process is running, do nothing. If it is not, start it. How would this be done. I am using Python 2.6 on Windows XP There are a couple of options, 1: the more crude but obvious would be to do some text processing against: os.popen('tasklist').read() 2: A more involved option would be to use pywin32 and research the win32 APIs to figure out what processes are running. 3: WMI (I found this just now), and here is a vbscript example
