问题 I have a jqgrid displaying a large amount data. The data is retrieved from the server periodically via a jquery ajax call (outside of the jqgrid logic). The retrieved data is compared to the data previously retried ( and stored as a var in js. it is served as the data for the jqgrid). if they are different the local data is refreshed, then trigger the jqgrid to reload. the jqgrid datatype is jsonstring. This solution is working quite well, except when the user have a filter value in the

问题 i made a flash air application for android and i need to download file and save to application local directory Thanks in advance.... 回答1: URLRequest and URLLoader will allow you to fetch some data from the internet, FileStream allows you to save it locally (FileReference if you want them to choose where to save it) as in <?xml version="1.0" encoding="utf-8"?> <s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns

问题 I'm using std::random_shuffle and srandom, and wonder if it's possible to constrain srandom()'s effect to local block of code. To be more precise, For a server application, I need to have different random seeds for different clients and keep using this pre-determined seed for random number generation per clients. Thank you 回答1: The routines you are looking for are srandom_r(3) and random_r(3) : http://www.kernel.org/doc/man-pages/online/pages/man3/random_r.3.html 来源： https://stackoverflow.com

问题 As known, returning local variable from function in C++, is unsafe, due to scoping. In Effective C++ Third Edition, Scott Meyers tells about this problem in item 21, at page 101. However, in conclusion he said, that right decision will be to write: inline const Rational operator*(const Rational& lhs, const Rational& rhs) { return Rational(lhs.n * rhs.h, lhs.d * rhs.d); } Isn't this also a bad practice, and this function is unsafe? UPD: Thanks everybody for explanation. 回答1: You can't actually

问题 I have a timer on a page in ASP.NET. After a certain period of time elapses, I want to disable the timer. I want to put a static variable in the timers tick event that will track how many seconds have elapsed. My question is, will this work? If user X and Y are viewing the page will they both have separate local static variables? What is the best method of shutting down an ASP.NET timer after a certain elapsed time? 回答1: No, it won't work. Static in VB.Net is syntactic sugar that hides a

问题 I wrote a script that is using slack API to parse AWS S3 files looking for strings or samples. As this is in testing, I'm using my local machine and ngrok to forward localhost traffic. The thing is that the generated files are getting stores in my machine and will be stored in server once the script is ready for production. Ideally, I'd like to avoid users needing to grab files from server. Do you think it's possible to store directly in user local machine? 回答1: No. Slack does not allow you

问题 I am using jquery-ui's autocomplete on two input fields of an HTML form in a Sinatra app. They work on my local machine but not on Heroku. Jquery-ui's datepicker works on this same page, so I know the jquery and jquery-ui javascript files are being loaded correctly. Also, I can see that the variable that I am using as the source for the autocomplete is actually getting populated from the database. There are no console errors as well. Here's the HTML: <form action="/add-event" method="post">
