as3 - dispatchEvent from a parent swf to a child swf

由 ☆樱花仙子☆ 提交于 2019-12-07 07:12:46
问题 I have one main "parent" swf that loads several other swfs. If something happens in the main swf I need to tell one of the child swfs about it. This seems to work well the other way around. Any of the children can simply dispatchEvent(), and I can set up the main swf to listen for the event. However, I can't get the child swf to catch any events dispatched by the parent. How is it done? 回答1: OK, so if you know most of this already, my apologies... but it seems a pretty common issue and isn't

Why does Ruby on Rails create new Sessions on every hit (sometimes)?

由 筅森魡賤 提交于 2019-12-07 05:37:22
问题 for some reason, the session handler in my RoR application seems to act weird in production for many users. I am using the default RoR ActiveRecord Session Store and in development everything works just fine. As long as I keep the browser open, one existing data row is being updated every time I modify the session, just like you'd expect sessions to work. When going to the production server, I personally observe the same behavior. However, when looking in the database, I see very many rows

How to invoke WPF Dispatcher in Nunit?

由 穿精又带淫゛_ 提交于 2019-12-07 03:33:59
问题 I want to test an application which renders a text block with a data field value. I would like to get the actual width and actual height, once the rendering completes. Everything works fine. The problem came first, when I tried to test the application. I'm unable to invoke the dispatcher from the test project. Following is the code. this.Loaded += (s, e) => { TextBlock textBlock1 = new TextBlock(); //// Text block value is assigned from data base field. textBlock1.Text =

问题 This question already has answers here : How do I get the UI thread's Dispatcher? (2 answers) Closed 4 years ago . In the constructor of an object i need to create a WPF mediaElement object: m_videoMedia = new MediaElement(); but the class can also be instantiated from a other thread so i need to use Dispatcher.Invoke(DispatcherPriority.Normal, (Action)(() => { m_videoMedia = new MediaElement(); })); But how can I get the right dispatcher instance in that constructor :s 回答1: You most likely

从SpringBoot到SpringMVC

由 ⅰ亾dé卋堺 提交于 2019-12-07 02:59:22
概述 用久了SpringBoot，深受其约定大于配置的便利性毒害之后，我想回归到SpringMVC时代，看看SpringMVC开发模式中用户是如何参与的。本文就来体验一下SpringMVC时代开发的流程。 注： 本文首发于 My 公众号 CodeSheep ，可 长按 或 扫描 下面的 小心心 来订阅 ↓ ↓ ↓ SpringMVC架构模式 一个典型的SpringMVC请求流程如图所示，详细分为12个步骤： 用户发起请求，由前端控制器DispatcherServlet处理 前端控制器通过处理器映射器查找hander，可以根据XML或者注解去找 处理器映射器返回执行链 前端控制器请求处理器适配器来执行hander 处理器适配器来执行handler 处理业务完成后，会给处理器适配器返回ModeAndView对象，其中有视图名称，模型数据 处理器适配器将视图名称和模型数据返回到前端控制器 前端控制器通过视图解析器来对视图进行解析 视图解析器返回真正的视图给前端控制器 前端控制器通过返回的视图和数据进行渲染 返回渲染完成的视图 将最终的视图返回给用户，产生响应 整个过程清晰明了，下面我们将结合实际实验来理解这整个过程。 SpringMVC项目搭建 实验环境如下： IntelliJ IDEA 2018.1 (Ultimate Edition) SpringMVC 4.3.9.RELEASE

Dispatcher is not coming on C# Windows Forms Application

由 喜欢而已 提交于 2019-12-07 01:31:08
问题 I have a C# Windows Forms Application with a progress bar. I want to progress that dynamically based on some method status. I have that method in a separate class, and am creating a new thread for that method, with a delegate to pass the status of the method to the parent thread. The same situation I am able solve in a WPF application using progressbar.Dispatcher but in a Windows Forms application there is no Dispatcher, even if I use the System.Threading namespace. progressbar.Dispatcher

Struts2源码阅读之Dispatcher

由 自作多情 提交于 2019-12-06 21:50:18
Dispatcher是Struts2的核心分发器，就好比SpringMVC的DispatcherServlet，它是完成url解析转向，读取对应Action的地方，相当于一个路由。 先看一段代码： private static ThreadLocal<Dispatcher> instance = new ThreadLocal<Dispatcher>(); 可以看到，Dispatcher也是使用ThreadLocal模式。在Struts2中大量使用了ThreadLocal模式，比如上次说到的ActionContext。 创建Dispatcher: public Dispatcher(ServletContext servletContext, Map<String, String> initParams) { this.servletContext = servletContext; this.initParams = initParams; } initParams配置在web.xml中的param参数. 接下来，主要会阐述init,serviceAction,cleanup这三个方法。 1.init init方法的主要工作是初始化配置文件，它会分七步载入各种配置文件，都是通过ConfigurationProvider接口进行的,这个接口提供init(),destroy()

Delayed Dispatch Invoke?

由 强颜欢笑 提交于 2019-12-06 17:23:55
问题 In WPF due to the intricacies on how the interface is updated I sometimes have to perform actions after a short delay. Currently I'm doing this simply by: var dt = new DispatcherTimer(DispatcherPriority.Send); dt.Tick += (s, e) => { dt.Stop(); //DoStuff }; dt.Interval = TimeSpan.FromMilliseconds(200); dt.Start(); But it's both a bit ugly and perhaps too much overhead to create a new timer each time (?) What's the best from a performance standpoint to do it, ie execute most promptly? And what
