dynamic

问题 So far as I know,C++/C doen't support dynamic array on stack . In the following delcaration : int data[n] ; // if the n is not decided at compiling time ,this leads to error But recently , I read some other guys code as following: //** It seems the n number can not be decided at compling time,but when I run it , if i fprintf the formation, each time i got the correct array size !!!!!! the G++ version is 4.7.1 Is this because the G++ 4.7.1 support C++11 x which allow dynamic array? **//

问题 Since getting started in Dart I've been watching for a way to execute Dart (Text) Source (that the same program may well be generating dynamically) as Code. Like the infamous "eval()" function. Recently I have caught a few hints that the communication port between Isolates support some sort of "Spawn" that seems like it could allow this "trick". In Ruby there is also the possibility to load a module dynamically as a language feature, perhaps there is some way to do this in Dart? Any clues or

问题 I realize that it goes against the strongly typed nature of C#, but I find that when working with dynamic objects in the language, some of the more useful features typically found in JavaScript or PowerShell are simply not practical. For example, the following C# code will fail at runtime and it's obvious why. dynamic x = 1.0; int y = x; But that makes the dynamic features of C# pretty limited when dealing with loosely typed data such as that produced by JSON payloads or CSV where subtle

问题 I have a website that is already completed in ASP.NET. I need to add a section at the bottom that holds a live streaming video chat (Flash Object), and I need it to persist over different page visits. e.g. I have profile.aspx and local.aspx that might be visited and I need the little chat frame at the bottom to persist between page changes. Here's a pic: alt text http://c3gl.com/pageper.jpg The only ways I can think to do this are... Make the whole website on page that just dynamically loads

问题 I apologize for this question length, but I think you'll all find it worth it. Before I begin, let me say that I was really trying to produce an isolated console application, but sadly that proved impossible. The bug does not happen in a console app. It doesn't happen in a self-contained ASP.NET app. It only happens when run within IIS 7.5 on Windows 7. The error seems related to the dynamic language runtime as it involves the combination of a __TransparentProxy (via WCF) and a dynamic

问题 I am trying to utilize a bit of dynamic gui activity in an application on Shiny server. My application needs a variable number of sliders created, depending on data that is input into my application. Specifically, I am trying to create sliders that set a value, one for each unique category in a input data table. I am able to successfully read my input table and create the sliders, using render UI, but I am stuck on how to best then manipulate the variable number of created input values set by

问题 I'm building a CKEditor 3.x plug-in that allows certain sections of HTML to be conditionally displayed by a separate viewer application that is tied in to our back-end systems. My CKEditor plug-in will be used to define these conditions, but I'm getting stuck on how to dynamically add UI elements to the plug-in dialog. After I select the 'AND' option in the last select UI element (see the screenshot), I want to dynamically add another 3 select UI elements, similiar to the first 3 select's. I

问题 I have an issue with creating buttons dynamically. I used the help provided by How can I dynamically create a button in Android? Although is does help tremendously it isn't exactly working with my specific situation. I am trying to create an array of buttons inside of a scroll view. These buttons will basically be created on the fly based off the answer to the query from a sqlite database. I havent implemented the database as of yet but im just using a for loop with a set variable to create

问题 I have an iframe that contains some content from a site. I want the iframe to adjust to 100% of the src content's height. Bit of a noob at js - here's what I'm working with: <iframe id="frame" scrolling="no" frameborder="0" src="http://www.srcwebsite.org"></iframe> <script type="text/javascript"> function resizeIframe() { var height = document.documentElement.clientHeight; height -= document.getElementById('frame').offsetTop; height -= 20; /* whatever you set your body bottom margin/padding

问题 I'm wondering if there is anything like Django's HTML templating system, for for CSS.. my searches on this aren't turning up anything of use. I am aware of things like SASS and CleverCSS but, as far as I can tell, these still don't solve my issue as I want to dynamically generate a CSS file based on certain conditions, so that a different CSS file would be served based on a specific user session... I want to minimize the use of javascript / AJAX for some things (since its for a legacy system
