问题 A few questions here: Is there anyway to keep iOS from freezing javascript on the page while scrolling? Does iOS freeze javascript when your in another tab or if you switch apps? Are there any other major javascript limitations on iOS? 回答1: iOS 6.x suspends all event timers in response to touch events like scrolling and has a tendency not to start up all the timers again once the event is done. It's a well known iOS 6 bug that is super-annoying. It pretty much breaks parallax and stuff. Some

问题 I got this message on the developer console stating that my application had frozen because of: ANR Broadcast of Intent { act=android.intent.action.SCREEN_OFF flg=0x40000000 } There was no stack trace because this was raised by a pre-Froyo user. It doesn't even tell me which activity within my application caused the error - although I'd guess it was my Game activity. This also matches my own experience that sometimes when my phone is running low on battery that my application will just freeze

问题 I've figured out that the problem is only with the Build Settings tab. So I am rewriting this post... If I select the project in the project navigator then click on Build Settings xCode hangs with the pin wheel several minutes. After I finally getting into Build Settings and as long as I have the project selected, any movement of the mouse or click will make it hang again. I have to get out of Build Settings to get things back to normal. I have tried cleaning the project and ultimately

问题 My operations group, and the devs are clueless to why this happens. Basically the server-side service of a client/server application hangs. We have been pushing new bugfixed versions and providing all kinds of logs to the devs, but they can't figure it out. To make it even harder to figure out, this is an application that works very closely with another application on the client side. I have no idea if I'm onto something here, as I have limited windbg experience, but this seems worth checking

问题 I have a python script that is running in the background with pythonw. If I close my laptop, it goes into sleep mode. and when I open my laptop, my program has little functionality and freezes after a couple of seconds. Is there any way that my script can tell if my computer is going into sleep mode, so that it can lie dormant and restart when I re-open my laptop? 回答1: You can catch WM_POWERBROADCAST window message with PBT_APMQUERYSUSPEND event inside it. To catch this message inside Python

问题 I'm trying to Freeze a Python 3.6.5 app into a standalone executable on Linux (Fedora 27 64 bit), using the default Python freeze.py utility. I have a checkout of Python 3.6.5 compiled, and I'm trying to freeze my application with the following (sanitized) commands: LOCAL_PYTHON=(path to my compiled local python directory) $LOCAL_PYTHON/python $LOCAL_PYTHON/Tools/freeze/freeze.py -p $LOCAL_PYTHON -P $LOCAL_PYTHON -o frozen myapp.py This freeze command seems to work fine, and generates the

问题 As the title says, when I run my OpenCL kernel the entire screen stops redrawing (the image displayed on monitor remains the same until my program is done with calculations. This is true even in case I unplug it from my notebook and plug it back - allways the same image is displayed) and the computer does not seem to react to mouse moves either - the cursor stays in the same position. I am not sure why this happens. Could it be a bug in my program, or is this a standard behaviour ? While

问题 I posted this question on the git issue tracker: https://github.com/pypa/pip/issues/2969 Can we have some manner of calling pip freeze/list within python, i.e. not a shell context? I want to be able to import pip and do something like requirements = pip.freeze(). Calling pip.main(['freeze']) writes to stdout, doesn't return str values. 回答1: There's a pip.operation.freeze in newer releases (>1.x): try: from pip._internal.operations import freeze except ImportError: # pip < 10.0 from pip

问题 I am building a WPF which has a button that execute a sql query in sql server (the query could take a long time to run). I want to use TPL for doing that. This code: var result = Task.Factory.StartNew(() => { command.ExecuteNonQuery(); }); gives this exception: ExecuteNonQuery requires an open and available Connection. The connection's current state is closed. I guess this is due to the fact that the query runs on a different thread and is not aware of the open connection. I have 2 questions:
