  • Deployment Error: Silverlight 4.0 w/WCF RIA Services in ASP.NET MVC 2 App

    - by Dennis Ward
    I've got an MVC 2 App with an RIA Services link to a Silverlight Application. On my local machine, all is well, but when I deploy to Discount ASP servers, neither the MVC controller nor the WCF RIA services called from silverlight function: A silverlight datagrid gets a load error: System.ServiceModel.DomainServices.Client.DomainOperationException: Load operation failed for query... The remote server returned an error NotFound. In the MVC page where I had a simple table that worked prior to adding an EF model and DomainDataSource, I now get the error: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. This is very similar to an issue I had before, but after upgrading from the betas of WCF/Silverlight 4, but the fix I had added there doesn't seem to work any longer. The link for that issue is: SL4/MVC2/WCF RIA Services = Load Error I'm really struggling with deploying, and could use some help if anybody can shed any light on this. Thanks! Dennis

  • Silverlight Ftp Upload

    - by Curtis
    Hi I'm working on trying to ftp a file to the server through a silverlight application. Where the location to upload the file on server file system, exists outside the sandbox area for the web server. In this case the web server root exists at "C:\test\www\" and the location to upload the file will exist at "C:\User\Uploads". In this scenerio i'm not sure if Http POST will work (doesn't that use the web server root). I just need to upload the file selected by the user to a different location that may exist outside the sandbox. With silverlight i'm thinking sockets are my last option based on the limited port range for silverlight being 4502-4532. Can i do this using WebClient and Http POST? Can i make an ftp connection through silverlight or javascript?

  • Silverlight 4 - MVC 2 ASP.NET Membership integration "single sign on"

    - by Scrappydog
    Scenario: I have an ASP.NET MVC 2 site using ASP.NET Forms Authentication. The site includes a Silverlight 4 application that needs to securely call internal web services. The web services also need to be publically exposed for third party authenticated access. Challenges: Securely accessing webservices from Silverlight using the current users identity without requiring the user to re-login in in the Silverlight application. Providing a secure way for third party applications to access the same webservices the same users credentials, ideally with out using ASP.NET Forms Authentication. Additional details and limitations: This application is hosted in Azure. We would rather NOT use RIA Services if at all possible. Solutions Under Consideration: I think that if the webservices are part of the same MVC site that hosts the Silverlight application then forms authentication should probably "just work" from Silverlight based on the users forms auth cookies. But this seems to rule out the possibility of hosting the webservices seperately (which is desirable in our scenario). For third-party access to the web services I'm guessing that seperate endpoints with a different authenication solution is probably the right answer, but I would rather only support one version of the services if possible... Questions: Can anybody point me towards any sample applications that implements something like this? How would you recommend implementing this solution?

  • Silverlight XML editor / syntax highlighting

    - by Gromix
    Hi, I am looking for a Silverlight text editor control that provides XML syntax highlighting. I found a few answers in Winforms or WPF, like here on Stackoverflow, but I didn't manage to convert them to Silverlight. The fact that Silverlight is missing System.Drawing is probably a big problem. The only text editor I found for Silverlight is RichTextEdit on Codeplex, but I don't think it is a suitable base for real-time syntax highlighting. Has anyone heard of such a control, or can provide hints on how to build one? Many thanks, Romain

  • Defining reliable SIlverlight 4 architecture

    - by doteneter
    Hello everybody, It's my first question on SO. I know that there were many topics on Silverlight and architecture but didn't find answers that satisfies me. I'm ASP.NET MVC developer and are used to work on architectures built with the best practices (loose coupling with DI, etc.) Now I'm faced to the new Silverlight 4 project and would like to be sure I'm doing the best choices as I'm not experienced. Main features required by the applications are as follows : use existing SQL Server Database but with possibility to move to the cloud. using EF4 for the data acess with SQL Server. exitensibility : adding new modules without changing the main host. loose coupling. I was looking at different webcasts (Taulty, etc.), blogs about Silverlight and came up with the following architecture. EF 4 for data access (as specified with the requirements) WCF RIA Services for mid-tiers controling access to data for queries and enabling end-to-end support for data validation, authentication and roles. MEF Support for enabling modules. Unity 2.0 for DI. The problem is that I don't know how to define a reliable architecture where all these elements play well together. Should I use a framework instead like Prism or Caliburn? But for now I'm not sure what scenarios they support. What's the best usages for Unity in Silverlight ? I used to use IoC in ASP.NET MVC for loos coupling and other things like interception for audit logging. It seems that for Silverlight Unity doesn't support Interception. I would like to use it to enable loose coupling and to enable to move to the cloud if needed. Thanks in advance for your help.

  • Calling SQL Azure's stored procedure in silverlight

    - by sweetsweet
    I have a silverlight application to call the SQL Azure's stored procedure and show the data. I use the service to call stored procedure, and it is working when it is run at VS 2008. But when I integrate in php page, the data is not shown. I think the service is not running. How can I call SQL Azure stored procedure without using service? I cannot use ADO.Net Entity Domain Model and LINQ to SQL(I don't have permission to access that database in GUI). I cannot connect to SQL Azure, so which method can I use to call SQL Azure stored procedure in silverlight? Please give me the information. {I don't know very much about that silverlight. To take the detailes of my project. I want to call SQL Azure's stored procedure. So, I tried to call that Stored Procedure from ADO.Net Entity Domain Model. The problem is I cannot access that SQL Azure database. It show "Buit_in function suer_sname is not supported in this version of SQL server. Therefore, I connect to that Stored Procedure in code beind and call that function in Service and to use that data in presentation layer, I add service reference in silverlight(I mean the service is at the same project). It is perfectly working when it is running at VS. So,I take out xap file and call that xap file in php. The silverlight is running in that PHP page but the data is not shown. I think the service is not hosted. So, how can I solve my problem? I use xampp to run my php page. }

  • Windows Mobile Silverlight?

    - by eidylon
    Is it possible to develop Silverlight apps to run on WinMo devices? I see all around searching on the web - in articles from 2008 and 2009 - that they were adding Silverlight support in WinMo 6.1, for example: Internet Explorer Mobile The new version of Internet Explorer Mobile adds the ability to easily view full-screen Web pages and multimedia on the Web with a smartphone. Microsoft's press release states the new version takes advantage of "Internet Explorer 6 technologies" and supports industry standards such as H.264, Adobe Flash and Microsoft Silverlight. The update will be available to mobile phone partners in the third quarter of 2008, with the first Windows Mobile phones using the new version expected to be available by the end of 2008. But I have found an SL app supposedly geared for mobile devices (as much as I hate weatherbug), but when i try going there in PIE on my WinMo 6.1 device, it shows me the little "get silverlight" image button, but clicking it doesn't do anything. So, what is the story? Is SL/WinMo development possible, or ?

  • How would you justify text in Silverlight?

    - by PaulJ
    Does anyone have any suggestions on how to justify read-only text (rendered into a TextBlock) in Silverlight 2? WPF supports text justification by way of the TextAlignment enumeration: public enum TextAlignment { Left, Right, Center, Justify // <--- Missing from Silverlight :( } However, Silverlight 2 only supports the following: public enum TextAlignment { Center, Left, Right } Any ideas or suggestions gratefully received.

  • Silverlight standard loading animation does not get displayed.

    - by Anne Schuessler
    Can anybody enlighten me as to how the standard Silverlight loading animations (the swirling blue balls) are embedded in a Silverlight application and how they work? I currently don't see it although loading the xap takes long enough for the loading animation to be displayed. The problem is that I'm creating a xap dynamically and trying to write it to the Response Stream which might somehow interfere with the way most Silverlight applications work. So maybe there's something missing from the original aspx page or ClientBin that should be there that has been lost by accident. I haven't found any helpful information about how the loading animation is integrated into Silverlight that could help me debug the problem so far. Does anyone know what the animation needs to triggered as expected?

  • Read cookies in silverlight

    - by Dharam Narayan
    hi, I have an ASP.NET MVC application. In this after user get Sign in .We set the a cookie for the user who logged in using FormsAuthentication.SetAuthCookie(userName, false). In other page we get the Cookies using the FormsAuthentication.GetAuthCookie(userName]) . This cookie values as string is then set in the Response.Cookies["username"].Value = cookiesvalue . We have .aspx page in the same application that downloads silverlight application .Silverlight reads the cookies using the code string[] cookies = HtmlPage.Document.Cookies.Split(';'); The problem is that once session expires in the application,silverlight cannot read the cookie value. After the session expires we again set the cookies in headers using the Response.Cookies["username"].Value = cookiesvalue . But still silverlight application cannot read this cookie . Thanks in Advance DNM

  • Blend 4 breaks VS2010 for Silverlight

    - by Adrian
    Hi, I had VS2010 running fine with Silverlight development. Then I installed Expression Blend 4. Now when I run VS2010 and try to debug a silverlight app I get an error saying "Unable to start debugging. The silverlight developer runtime is not installed. Please install a matching version." I've tried uninstalling silverlight tools, and reinstalling them from scratch (the latest april version). But I still get the same message. So basically I'm now unable to do VS2010 SL development. I'm on the verge of just rolling back to my last system restore point and giving up on Blend. But if I do that I'd be worried that Product Activation would never allow me to reinstall it in the future, since the MSDN download page implies I'm only ever allowed to install it on a single machine. Any help appreciated. Thanks

  • Diffie-Hellman in Silverlight

    - by cmaduro
    I am trying to devise a security scheme for encrypting the application level data between a silverlight client, and a php webservice that I created. Since I am dealing with a public website the information I am pulling from the service is public, but the information I'm submitting to the webservice is not public. There is also a back end to the website for administration, so naturally all application data being pushed and pulled from the webservice to the silverlight administration back end must also be encrypted. Silverlight does not support asymmetric encryption, which would work for the public website. Symmetric encryption would only work on the back end because users do not log in to the public website, so no password based keys could be derived. Still symmetric encryption would be great, but I cannot securely save the private key in the silverlight client. Because it would either have to be hardcoded or read from some kind of config file. None of that is considered secure. So... plan B. My final alternative would be then to implement the Diffie-Hellman algorithm, which supports symmetric encryption by means of key agreement. However Diffie-Hellman is vulnerable to man-in-the-middle attacks. In other words, there is no guarantee that either side is sure of each others identity, making it possible for communication to be intercepted and altered without the receiving party knowing about it. It is thus recommended to use a private shared key to encrypt the key agreement handshaking, so that the identity of either party is confirmed. This brings me back to my initial problem that resulted in me needing to use Diffie-Hellman, how can I use a private key in a silverlight client without hardcoding it either in the code or an xml file. I'm all out of love on this one... is there any answer to this?

  • Silverlight Data Access - how to keep the gruntwork on the server

    - by akaphenom
    What technologies are used / recommended for HTTP Rpc Calls from Silverlight. My Server Side stack is JBoss (servlets / json_rpc [jabsorb]), and we have a ton of business logic (object creation, validation, persistence, server side events) in place that I still want to take advantage of. This is our first attempt at bringing an applet style ria to our product, and ideally we keep both HTML and Silverlight versions. For better or worse the powers that be have pushed us down the silverlight path, and while flex / java fx / silverlight is an interesting debate, that question is removed from the equation. We just have to find a way to get silverlight to behave with our classes. Should I be defining .NET Class representation of our JSON objects and the methodology to serialize / deserialize access to those objects? IE "blah.com/dispenseRpc?servlet=xxxx&p1=blah&p2=blahblah creating functions that invoke the web request and convert the incomming response string to objects? Another way would be to reverse engineer the .NET wcf(or whatever) communications and implement the handler on the Java side that invokes the correct server side code and returns what .NET expects back. But that sounds much trickier. T
