How do you configure a MessageInspector when using StandardEndpoints in WCF REST 4.0

阅读更多关于 How do you configure a MessageInspector when using StandardEndpoints in WCF REST 4.0

问题 I'm trying create and configure a Message Inspector to perform some authentication of a WCF Rest HTTP request. I'm using 4.0 so trying to steer clear of the WCF Starter Kit although I have managed to get an old RequestInterceptor working in the way I want. The problem with using RequestInterceptor is that I lost the automaticFormatSelectionEnabled features provided by WebHttpBehavior which I really want to keep. So my question is how do I configure the Message Inspector in a way that I still

I'm working on a project where I can generate Word documents, one of the functionalities is to define a table of contents. I want my TOC to be a sortable jQuery list for sorting the chapters. I'm retreving the data recursivly from a MySQL table, which functions as expected. Since I found there are some strange behaviors in IE7 (and possible other versions) I switched back to basics and tried the following in a simple HTML file without any DB-generated structure. <!doctype html> <html> <head> <script type="text/javascript" src="./jquery-1.3.2.js"></script> <script type="text/javascript" src=".

What's the best way to attach behavior to a Meteor Collection?

阅读更多关于 What's the best way to attach behavior to a Meteor Collection?

问题 In Meteor, when you retrieve a record from a database, it's only a record. So if I have a collection called Dogs , a dog might have fur: 'brown' or breath: 'stinky' , but it doesn't have a bark() method. Obviously, I could create some functions that expect a dog as an argument and then perform operations on that dog . I could even encapsulate all these functions into a single constructor. I'm not crazy about this approach, but if someone's got a clean and sensible way to do it, I'm all ears.

Behavior 的简述行为简单来说是组件的扩展，可以对组件的属性，方法，事件（yii2组件的三大要点）进行扩展而无需改动组件现有的代码逻辑。即此行为所拥有的属性，方法，事件，都会被绑定它的组件 "获取" 到。所以 yii2 的行为在一定程度上也是对 Event 的封装，你可以在行为里定义需要扩展的属性，方法，也可以注册事件，让组件可以做到绑定此行为，即注册了某事件的功能。我们知道，框架在执行过程中有很多系统级别执行节点，在这些节点 yii2 使用 Event 来进实现行钩子机制。比如我们调用一个 Action 有 beforeAction 和 afterAction 的执行节点，调用 Model 的 validate 方法有 beforeValidate 和 afterValidate 的执行节点，执行到相应的节点便会触发相应的事件，事件去检查有无注册的钩子，有的话即会触发。而行为则可以为某组件方便的实现此功能。 yii\base\Model 中的 validate 方法的前后执行节点我如果在某行为中注册了model的这两个事件，那么任何继承至 yii\base\Model的组件只要绑定了此行为，都会被注册这两个事件。 yii\base\Behavior 基类 yii\base\Behavior::$owner //行为所有者肯定是某组件对象 yii

Coordinator layout custom layout behavior never getting called

阅读更多关于 Coordinator layout custom layout behavior never getting called

Firstly, I'd like to preface this with my lack of knowledge about the coordinator layout. I'm merely following tutorials I found online and am curious why my behavior isn't working. Does the child view inside of coordinator layout have to be app bar layout? Or are you able to put any view inside there. Also, when I define the res-auto namespace it doesn't give me the option for layout_behavior. Usually android studio will auto-complete if a function is available and it didn't. Although, if I type out layout_behavior it doesn't complain. So maybe it's working...? Regardless, I've defined my own

RadioButtons with behavior bind to single property

阅读更多关于 RadioButtons with behavior bind to single property

I'm having few RadioButtons and I don't want to bind "IsChecked" property of each one of them to unique property in the code. I want to have a single property like "CurrentSelected" and according to that to set the "IsChecked". In addition I don't want to use converters. I tried to use the behavior "ChangePropertyAction" but it looks like it's working only in one way. here is my code: <RadioButton x:Name="UpRadioButton" Margin="5" Content="Up" > <i:Interaction.Triggers> <ei:DataTrigger Binding="{Binding IsChecked, ElementName=UpRadioButton}" Value="True"> <ei:ChangePropertyAction TargetObject=

What is the difference between `>>> some_object` and `>>> print some_object` in the Python interpreter?

阅读更多关于 What is the difference between `>>> some_object` and `>>> print some_object` in the Python interpreter?

In the interpreter you can just write the name of an object e.g. a list a = [1, 2, 3, u"hellö"] at the interpreter prompt like this: >>> a [1, 2, 3, u'hell\xf6'] or you can do: >>> print a [1, 2, 3, u'hell\xf6'] which seems equivalent for lists. At the moment I am working with hdf5 to manage some data and I realized that there is a difference between the two methods mentioned above. Given: with tables.openFile("tutorial.h5", mode = "w", title = "Some Title") as h5file: group = h5file.createGroup("/", 'node', 'Node information') tables.table = h5file.createTable(group, 'readout', Node, "Readout

How can I disable Text Selection temporarily using JavaScript?

阅读更多关于 How can I disable Text Selection temporarily using JavaScript?

this is a bit of a specific question so I'll get right to the point. I'm working on a short and simple drag and drop routine for part of a web application, and although the dragging and dropping bit works fine, the site goes all ugly-tastic during the operation because the browser still does the default operation and works on text selecting. I've tried a few solutions mainly involving returning false from the mousedown or click events, and although they disable text selection in some browsers, they also seem to disable the mouseup event entirely, ruining the "drop" bit of the script and
