I know there is already a question about the performance of Flex, JavaFX, and Silverlight. My question is a bit more broad: We are evaluating the merits of JavaFX and Silverlight to serve as the GUI technology that controls/configures our back-end service (currently written

问题 There have been plenty of articles about how to use reflection and LINQ to raise PropertyChanged events in a type-safe way, without using strings. But is there any way to consume PropertyChanged events in a type-safe manner? Currently, I'm doing this void model_PropertyChanged(object sender, PropertyChangedEventArgs e) { switch (e.PropertyName) { case "Property1": ... case "Property2": ... .... } } Is there any way to avoid hard-coding strings in a switch statement to handle the different

问题 I am used to developing with N-Tier architecture, i.e. Data Access Layer, Business Logic Layer, etc Can anyone provide any advice or links about the best location for my business logic? Do I put all of this into classes within the Models folder of my Silverlight application? Paul 回答1: Business logic, as well as the data, is typically part of the Model layer in MVVM. The View is the visuals, and the ViewModel is the "glue" that lets you work with the business specific logic and data. Anything

问题 I've seen a lot of links to MSDN and "works on my machine!" answers so I'd like to ask my question with the exact steps to duplicate what I'm doing. Because we are using an already existing webservice, I'm asking with the context of having a webservice hosted outside of my project, unlike many of the tutorials and videos online. So here goes: *** Create a new ASP.NET webservice project. It will come with an existing Service.asmx file exposing a "HelloWorld" web method. View in browser, hit

问题 How to make async requests to a webservice from a Thread? 回答1: Here is the short answer without a load of explanations. Before calling the Async method on your Client object make sure you are not running on the UI Thread:- System.Threading.ThreadPool.QueueUserWorkItem( o => { try { svc.SomeMethodAsync(); } catch (err) { // do something sensible with err } }); Now the corresponding completed event will occur on a ThreadPool thread not the UI Thread. 回答2: Here is a solution using WCF. Service

问题 I have a big project where my application keeps retaining a page which I navigated away from. The page is only used minimal, and have a lot of graphics, I therefore want it to be completely removed from memory. I therefore used the following NavigationService.RemoveBackEntry(); Using the profiler I saw that, the above snippet made sure that I would only have 1 instance of the page. But as it is heavy with graphics I still want it to be completely removed from memory, i.e. no instances in the

问题 provider.OptionsSet += delegate { provider.FinishedLoading(); }; 回答1: Nice demonstration how converters get this dramatically wrong, they have for a long time. The += operator isn't VB.NET syntax, AddHandler is required to subscribe events. Where the Do comes from is anybody's guess. The lambda can't be a Function, except for the very rare cases where the delegate type returns a value. Three bugs in one line, you don't stand a chance. You need VS2010 to write a Sub lambda. Like this: Module

问题 I have a button to which i add a image as its background but when i press the button i get a square on the background of the button (highlight). How can i remove this? <Button VerticalAlignment="Top" HorizontalAlignment="Left" BorderBrush="Transparent" Click="FirstCubeSelected" x:Name="cube1Button" Padding="0" Margin="1,0,-1,0"> <Image x:Name="buttonImage" Source="/images/cub2onbtn.png" Width="176" Height="176" /> </Button> I usually do this in expression blend but i don't have access to it

问题 I see a lot of talk how HTML5 video tag will kill Flash. But while video is the most widely used part of Flash/SL, it's only a small part of their technical abilities. For instance you can write a game using full 3D graphics and socket connections in Flex, and serious business applications, etc. Is the thinking that Javascript will kill those parts of Flash/Flex/SL? Because while that seems feasible now for even quite rich web-apps, what about any kind of high-performance app like real-time
