Single-shot event subscription

阅读更多关于 Single-shot event subscription

问题 I'm fairly convinced that this isn't possible, but I'm going to ask nonetheless. In order to make a single-shot subscription to events, I frequently find myself using this (self-invented) pattern: EventHandler handler=null; handler = (sender, e) => { SomeEvent -= handler; Initialize(); }; SomeEvent += handler; It's quite a lot of boiler-plate, and it also makes Resharper whinge about modified closures. Is there a way of turning this pattern into an extension method or similar? A better way of

如何为网站添加浏览器选项卡图标（favicon）？

阅读更多关于如何为网站添加浏览器选项卡图标（favicon）？

我一直在网站上工作，我想在浏览器标签上添加一个小图标。如何在HTML中执行此操作以及在代码中我需要放置它的位置（例如标题）？我有一个 .png 徽标文件，我想将其转换为图标。相关： HTML在浏览器选项卡上设置图像。 #1楼我已经成功地为我的网站做了这个。唯一的例外是，SeaMonkey浏览器需要在 <head> 插入HTML代码; 然而，其他浏览器仍然会显示favicon.ico而不插入任何HTML。此外，IE以外的任何浏览器都可以使用其他类型的图像，而不仅仅是.ico格式。我希望这有帮助。 #2楼要让Chrome显示页面图标（favicon），您需要从托管服务器检查您的网站，或者您可以在PC上开发和测试您的网站时使用本地主机。 #3楼我建议您尝试 http://faviconer.com 将.PNG或.GIF转换为.ICO文件。您可以在一个.ICO文件中创建 16x16 和 32x32 （用于新的视网膜显示）。没有IE和Firefox的问题 #4楼我找到的最好的是 http://www.favicomatic.com/ 我说得最好，因为它给了我最清晰的图标，并且在转换后不需要编辑。它会产生16x16和32x32的favicons并引用它们“每个该死的大小，先生！” 此外，他们的网站看起来很酷，易于使用。它们还会生成您需要用于生成的文件的html。

How to reduce boilerplate when initializating classes from JSONs in Python 3.5?

阅读更多关于 How to reduce boilerplate when initializating classes from JSONs in Python 3.5?

问题 I have a set of python webservices that work with data objects they get via a JSON POSTs. In my old services I have a lot of boilerplate to (de)serialize and check JSONs for each object. With Python 3.5s new typing and PEP 484 I have the feeling that could be substantially reduced. Is it worth it? Does anyone have a good solution for it? Additional info My old boilerplate looks like this for every object: class Data: class Nested1: def __init__(self, nested1_flat1): self.nested1_flat1 =

问题 I'm developing a credential provider and filter. I have some problems with lock scenario. First, I have tried the SampleAllControlCredentialProvider from here. And it works. Even when I logon and lock it afterward, it shows my credential. Second, I tried making my own credential provider filter by adding some lines of codes. The filter is filtering out the windows' credential, only my credentials are allowed to appear. These are my addition of codes: In CSampleProvider.h, I make the class to

问题 In my search for a good social login package for App Engine, I am giving gae-boilerplate a try. But I find there is no documentation except the readme file, which I think it is not enough at all. I have many questions, among them: Should the boilerplate be used as a library or download and modify as needed? How should the boilerplate be updated? What does each model do? Where should my templates go? Should I have a different routes file? Should I derive my Handlers from BaseHandler? In

Can Java help me avoid boilerplate code in equals()?

阅读更多关于 Can Java help me avoid boilerplate code in equals()?

问题 I implement equals() the Java 7 way: @Override public boolean equals(Object obj) { if (this == obj) return true; if (obj == null) return false; if (getClass() != obj.getClass()) return false; MyClass other = (MyClass) obj; return Objects.equal(myFirstField, other.myFirstField) && Objects.equal(mySecondField, other.mySecondField); } Is there a way to reduce the code duplication? I would prefer something like @Override public boolean equals(Object obj) { if (Objects.equalsEarlyExit(this, obj))

How in Camel to add and start routes dynamically?

阅读更多关于 How in Camel to add and start routes dynamically?

问题 I'm trying to remove some boilerplate from routes in Camel. For example, let's consider the two routes, which are similar and most of their inner stuff could be generated. I've created a component "template", which creates TemplateEndpoint , and modifyed an XML config to use the template component. A custom method TemplateEndpoint.generateRoute (adding route definitions) is being called from StartupListener (defined in TemplateEndpoint.setSuffix ). So while Camel context starting, route
