freeze

问题 What is the opposite of Object.freeze or Object.seal ? Is there a function that has a name such as detach? 回答1: There is no way to do this, once an object has been frozen there is no way to unfreeze it. Source Freezing an object is the ultimate form of lock-down. Once an object has been frozen it cannot be unfrozen – nor can it be tampered in any manner. This is the best way to make sure that your objects will stay exactly as you left them, indefinitely 回答2: I think you can do, using some

问题 Many types in WPF derive from Freezable . It provides immutability to mutable POCO objects and, apparently, allows for improved performance in certain situations. Has anyone found that freezing objects within their WPF application has greatly improved performance? If so, then which items gave the biggest performance difference when being frozen? (Note that I have posted a similar but different question too) 回答1: You might be interested in my experiences with Freezable: I once wrote a PDF

问题 Original question: This method is supposed to change the image being displayed on a JFrame gradually into another image. However, without some way to slow it down, it just seems to change from one image to the new image. In order to slow it down, I put in a Thread.sleep(1000) so the changes wouldn't happen instantly. However, with this line in there, my program freezes completely. No error message, no nothing. Can anyone please help me out? Suggest a better method to slow it down, or how this

问题 I put a lot of information in this issue because I have no idea what will be relavent Issue: I am having an issue with a program I am working on where when running it, it will freeze my whole computer and return no error (I am completely incapable of doing anything CTRL+ALT+DEL doesn't even work). This program accepts a connection from a android client and atm the android client is not configured correctly so the connection is being rejected. Question: How can I stop my program from freezing

问题 I need check in my database names who are duplicated and change this name to avoid duplicates. I using script suggested by @Jefré N. function eliminateDuplicates() { var repeats = {}; var error = false; //cache inputs var $inputs = $("input[type='text']"); //loop through inputs and update repeats for (i = 0; i < $inputs.length; ++i) { //cache current element var cur = $inputs[i]; //remove class $(cur).removeClass("double-error"); //get text of this element var text = $(cur).val(); //no text -

问题 Several users of my VSTO add-ins report hangs that occur when a "Save as" dialog should be displayed. This happens with an Excel add-in as well as a Word add-in. Interestingly, both applications also tend to hang when invoking the "Save as" command on a document. I am having a hard time to troubleshoot this because the entire application just freezes after // using System.Windows.Forms; SaveFileDialog dlg = new SaveFileDialog(); // lines to configure dlg left out dlg.ShowDialog(); When

问题 I would like to build my own coroutines in Prolog. I'd like to add some extra functionalities. 回答1: One possible solution would be to use the term-expansion mechanism provided by some Prolog systems and Logtalk to rewrite calls to e.g. the freeze/2 predicate to do the extra steps you want. One must be careful, however, to not expand a call to a predicate into another goal that calls the same predicate as goal-expansion is recursively applied until a fixed-point is reached. The Logtalk

问题 A code below is in a thread. Tf1 := TFileStream.Create(LogsPath,fmOpenRead or fmShareDenyNone); ... str:=TStringList.Create; str.LoadFromStream(tf1); ... SynEditLog.Lines.Assign(str); // I do this with Synchronize There are 30 000 strings in a text document. A form becomes frozen while assigning those strings to SynEdit. If to load string by string it takes me 40 sec... If to use Assign - 8 sec. How to prevent this form's state? Thanks!!! 回答1: I don't think Application.ProcessMessages is

问题 My goal is to grab keywords from Google Keyword Planner, as the API does not support getting search volume in last 24 months but 12 months only. I use maily SimpleBrowser, so I am new with CasperJS, I googled some scripts, read documentation and then combined following script. I can login to Google, even to Adwords dashboard, but when I try to access KeywordPlanner CasperJS freezes, any idea? JS script /** * Basic vars * @type Module utils|Module utils */ var utils = require('utils'); var

问题 I would like to write a loop that checks the value of a variable has changed. There's no event that fires to tell me the value has changed. The application doesn't support multi threading. How to achieve this without causing app to freeze ? The aim is this: Application starts ... loop Check variable value If changed then exit if timedOut then exit While loop causes application to freeze. Thank you. * Edit * This is what I'm after (this code is written by Remy Lebeau): const APPWM_COM_EVENT
