How to Thread.Sleep in BeginInvoke

由 旧时模样 提交于 2019-12-02 02:16:07
I tried to update a TextBox.Text to display from 1 to 10 with an internal of 1 second with the following code. I do not understand why the entire UI sleeps for 10 second before the text is updated to 10, as I though the Thread.Sleep(1000) should belong to a separate background thread created by Dispatcher.BeginInvoke . What is wrong with my code? Thread t1 = new Thread(new ThreadStart( delegate() { this.Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(delegate() { for (int i = 1; i < 11; i++) { mytxt1.Text = "Counter is: " + i.ToString(); Thread.Sleep(1000); } })); })); t1.Start();

Assist the UI Dispatcher to handle a flood of method invocations

问题 The following post has become a bit *longer* than expected I apologize for that but maybe you'll find it interesting to read and maybe you have an idea to help me :) I am developing a small application whose GUI consists of a number of List controls. Each List control has a thread associated with which is permanently producing strings that are being added to the list. To allow the List controls being updated by different threads I built an extended ObservableCollection that asynchronously

Spring returns HTTP 405 for every HTTP POST which isn't authorized

由 ぐ巨炮叔叔 提交于 2019-12-02 00:33:30
It seems like Spring isn't routing/authorizing HTTP POST requests correctly. When I send a HTTP POST request I always get "405 Method Not Allowed" response and this in the log file: org.springframework.web.servlet.PageNotFound - Request method 'POST' not supported The controller allows POST for the URL: @RequestMapping(value = "/mypostreq", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE) @Secured("ROLE_USER") public String mypostreq(@RequestBody String callBody, HttpServletRequest req, HttpServletResponse res) { return ""; } Here is the web.xml configuration: <context

Dispatcher.BeginInvoke not being executed in one case

由 倖福魔咒の 提交于 2019-12-01 23:45:37
I'm trying to fix a bug in an existing application, where in a single case, a dispatched event is not being executed. In our application, there are several services implementing a common abstract class (AbstractService). The issue I've got occurs when a service saves an entity and has to raise a notification in the UI thread. Relevant part of AbstractService: public abstract class AbstractService<TEntity, TData, TInfo> : IDataProvider, IAbstractService where TEntity : AbstractEntity, new() where TData : AbstractData<TEntity> where TInfo : IEntityInfo { [...] protected virtual void

SpringBoot之DispatcherServlet详解及源码解析

由 筅森魡賤 提交于 2019-12-01 23:05:27
在使用SpringBoot之后，我们表面上已经无法直接看到DispatcherServlet的使用了。本篇文章，带大家从最初DispatcherServlet的使用开始到SpringBoot源码中DispatcherServlet的自动配置进行详解。 DispatcherServlet简介 DispatcherServlet是前端控制器设计模式的实现，提供了Spring Web MVC的集中访问点，而且负责职责的分派，而且与Spring Ioc容器无缝集成，从而可以获得Spring的所有好处。 DispatcherServlet作用 DispatcherServlet主要用作职责调度工作，本身主要用于控制流程，主要职责如下： 文件上传解析，如果请求类型是multipart将通过MultipartResolver进行文件上传解析； 通过HandlerMapping，将请求映射到处理器（返回一个HandlerExecutionChain，它包括一个处理器、多个HandlerInterceptor拦截器）； 通过HandlerAdapter支持多种类型的处理器(HandlerExecutionChain中的处理器)； 通过ViewResolver解析逻辑视图名到具体视图实现； 本地化解析； 渲染具体的视图等；

Confusion about Refreshing the UI in WPF

由 早过忘川 提交于 2019-12-01 21:21:36
问题 I have heard that this refreshes the UI but why so? Dispatcher invokes this empty action and thats it there is no call InvalidateMeasure() which would trigger the UI to re-measure and re-arrange and re-render inside the action. Where is here the measure and arrange process to update/refresh the UI? private static Action EmptyDelegate = delegate() { }; public static void Refresh(UIElement uiElement) { uiElement.Dispatcher.Invoke(DispatcherPriority.Render, EmptyDelegate); } Any help? EDITED: I

精通Spring Boot——第一篇：DispatcherServlet和Multipart配置

由 你说的曾经没有我的故事 提交于 2019-12-01 16:34:53
如果大家搭建过SpringMVC应用，那么一定会写个几个xml配置文件，如 application.xml, spring-mvc.xml 等。一般来说，我们搭建项目的初始步骤如下： 初始化Spring MVC 的DispatcherServlet; 添加转码过滤器(HttpMessageConverter)，保证客户端请求都能正确的编码 搭建视图解析器（view resolver)，告诉Spring去哪里查找视图，以及视图方言（如Freemarker, Thymeleaf等）。 配置静态资源（css,js,image等） 配置mulpart解析器，保证文件上传正常。 配置一些错误处理，AOP切面日志等。 当我们开始使用SpringBoot来搭建我们的Web项目的时候，你会发现，这些事情SpringBoot默认都帮你处理了。 SpringBoot原则是约定优于配置，并且默认情况下，会在你的项目中使用这些约定。 接下来，让我们来了解下，幕后发生了什么？ 首先让我们新建一个SpringBoot项目，并在src/main/resources/中的application.properties增加一行： debug=true 。 OK，现在我们启动下项目看看控制台的输出。 ============================ CONDITIONS EVALUATION REPORT ==
