• Hierarchical templating multiple object types in silverlight

  - by Dan Wray

  Is it possible and if so what is the best way to implement the following hierarchical structure in a silverlight (4) TreeView control? (where Item and Group are classes which can exist in the tree). Group | |-Item | |-Group | | | |-Item | | | |-Item | |-Item The structure could of course be arbitrarily more complex than this, if needed. HierarchicalDataTemplates appear to be the way to approach this, but I'm specifically having trouble understanding how I might apply the template to interpret the different classes correctly. A similar question was asked for WPF, the answer for which made use of the TargetType property on the HierarchicalDataTemplate, but I am uncertain whether that property is available in the silverlight version since I don't appear to have access to it in my environment.

• Using long polling with WinForms Clients in .NET

  - by user544538

  Hi We need to develop a .NET application, basically a WinForms client, which needs to be notified of changes only from the server to update the UI only in case of necessity and not every time. We initially thought of NetTCPBinding but understood that it has problems with firewalls across domains and secure networks. We now consider long-polling as a viable option but we could only find this being used with WPF and XAML clients. For example, http://code.msdn.microsoft.com/duplexhttp But we could not find anything with WinForms. My opinion is that long-polling has to do with WCF and does not matter what UI technology is used (within .NET). Do you think it is possible to use long-polling with a custom WCF channel for WinForms? I am on the way to develop a POC but dont have much time. Any help in the right direction is much appreciated. Thanks much Charles

• WCF - problem with local service (The server has rejected the client credentials.)

  - by H4mm3rHead

  Hi, I have a simple setup, a WPF application running on the machine and a WCF service hosted within a Windows Service on the same machine (always on the same machine). When i debug on one computer i can easily access the local WCF Service. When i run it on another machine i get an error: "The server has rejected the client credentials." Some of my observations are, that at my local machine i have no domain/network. Its my home machine. When at a customers site, it will not run, and gives the above error. Anyone got any ideas on why this is different on these computers? /Brian

• Josh Smith's MVVM Demo App: Add commands to MainWindowViewModel's command list

  - by MAD9

  I have a question concerning Josh Smith's famous demo app on MVVM. I try building a "real" application around it to learn WPF. He creates this CommandsList in the MainWindowViewModel containing 2 Commands (create new and view all customers). This list is readonly (why? any particular reason?). I thougt it would be nice to add and remove some commands, depending on the workspace that is currently selected. Like edit or delete a customer when it has the focus and so on. How would I accomplish this?! Can I just make it a normal list and add commands? Or bind the Commands-View to a commands list of the selected workspace instead of the MainWindow? How? Any other ways? Please share your ideas! Thank you very much!

• Creating a Silverlight DataTemplate in code

  - by Nick R

  How do I create a silverlight data template in code? I've seen plenty of examples for WPF, but nothing for Silverlight. Edit: Here's the code I'm now using this for, based on the answer from Santiago below. public DataTemplate Create(Type type) { return (DataTemplate)XamlReader.Load( @"<DataTemplate xmlns=""http://schemas.microsoft.com/client/2007""> <" + type.Name + @" Text=""{Binding " + ShowColumn + @"}""/> </DataTemplate>" ); } This works really nicely and allows me to change the binding on the fly.

• 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

• Good Silverlight Custom ItemsControl Tutorial

  - by Steve Brouillard

  I'm afraid my Google-Foo is failing me again today. I'm trying to find a good tutorial on creating custom ItemsControls in Silverlight (though I imgaine a WPF version might work as well). I'm trying to create a custom ItemsControl that will be something of a virtualized ListBox. What I'm trying to accomplish isn't really similar enough to the current ListBox control to justify trying to modify the existing control, so I figure a custom one is in order here. I have a vague concept of how to accomplish it, but there are definite holes in my understanding. Thanks in advance

• WCF <operation>Async methods not generated in proxy interface

  - by Charlie

  I want to use the Asnyc methods rather than the Begin on my WCF service client proxy because I'm updating WPF controls and need to make sure they're being updated from the UI thread. I could use the Dispatcher class to queue items for the UI thread but that's not what I'm asking about.. I've configured the service reference to generate the asynchronous operations, but it only generates the methods in proxy's implementation, not it's interface. The interface only contains syncronous and Begin methods. Why aren't these methods generated in the interface and is there a way to do this, or do I have to create a derived interface to manually add them?

• Silverlight 4 HttpWebRequest user agent string is null

  - by Dan B

  The problem I have a page with a silverlight object. It attempts to retrieve XML from the page. But I am struggling with a security exception. I have this code working brilliantly in WPF. When using a website hosting a silverlight application with the same code, the user agent string of the HttpRequest object is null (and seemingly cannot be set). In fact there is no header information at all - this causes a security exception when attempting to make my asynchronous call. The question Why is the user-agent string (and header information) null in my silverlight 4 application when making an asynchronous call using HttpWebRequest? Thanks in advance!

• Consumed WCF service returns void although return type (& value) specified

  - by Abs

  I have a WCF service that I am attempting to connect to via a console application for testing (although will move to WPF for the final interface). I have generated the proxy, added the service reference to my project in visual studio and I can see all the methods I have created in my WCF interface: SupportStaffServiceClient client = new SupportStaffServiceClient("WSHttpBinding_ISupportStaffService"); client.myMethod(message); However when I call a method, which in the WCF interface is specified as returning a value, the method returns void in the console application. client.getMethod(message); The WCF service method is definitely returning a message, I'm just unsure as to why the client cannot "see" the return.

• DirectX application doesn't work over Remote Desktop

  - by emddudley

  I have a WPF application which has a DirectX component within it. This component does not work over Remote Desktop--it just shows a corrupted image. The application works fine when not using Remote Desktop. In trying to debug the problem I installed the February 2010 DirectX SDK. Now, when I run the program on the computer with the SDK and Remote Desktop to it from a separate computer, the component works just fine. However the opposite does not work--trying to use the application over Remote Desktop when it is running on the computer without the DirectX SDK (it has the original problem with the corrupted image). I have already compared the loaded DLLs (using Process Explorer) between running the application on my SDK machine and non-SDK machine. They both are loading the same DLL versions. What else could be causing this behavior?

• How do I base a style on a Silverlight toolkit theme style

  - by Ian Oakes

  I've being trying to add a theme from the Silverlight toolkit to a project. In the project there are a number of existing styles used in the layout. The problem is when any control has an explict style applied to it does not receive any attributes of the style from the theme. In WPF I would use something like BasedOn={x:Type TextBox}, but this is not supported in Silverlight. I've considered going through the theme and setting a key for every style and then using BasedOn to create both an implicit style to use with the ImplictStyleManager, as well as another explicit style for use with the existing styled controls. Have you got any better ideas?

• Debugging with Visual Studio 2010 and VB.NET: Immediate fails due to proection level

  - by marco.ragogna

  It happens quite frequently, more times per day, that with Visual Studio 2010, during the debugging, when I used Immediate commands like: ? NamedVariable I receive the following error: 'NamedVariable' is not declared. It may be inaccessible due to its protection level. In this case also other debug features seems gone, but I can set breakpoints, step into, step over, etc. The solution is stop debugging, clean and rebuild the project, and retry. I am developing a VB.NET Windows Forms application, but it happened with VB.NET WPF projects too. I never had this behavior with VS 2008. Is this a known bug or could it be a problem of my environment/installation? Do you have any idea how to solve this little, but annoying issue?

• Cannot obtain value of local or argument 'hwndSource' as it is not available at this instruction poi

  - by Dänu

  Hey Guys I'm playing around with Interops and I thought: "Hey let's code something that accesses the clipboard ..." so I googled and found some articles (yeah I'm doing it with WPF - .Net 3.5). However the following method generates an error (as seen in the title) and throws a stackoverflow. private void Window_SourceInitialized(object sender, EventArgs e) { // Hook to Clipboard base.OnSourceInitialized(e); HwndSource hwndSource = PresentationSource.FromVisual(this) as HwndSource; if (hwndSource != null) { installedHandle = hwndSource.Handle; viewerHandle = SetClipboardViewer(installedHandle); hwndSource.AddHook(new HwndSourceHook(this.hwndSourceHook)); } // End Hook to Clipboard } I have (really) no idea what's going on there. Any Ideas?

• Recommend .NET data access layer/middle tier

  - by Simon G

  Hi, I'm currently creating an MVC application that will likely to expand to include a silverlight, wpf and possible windows phone all using the same data. So I've created a class library to keep all my objects in and I've created the MVC app. My question is what would be the best way to access the data? Taking into account possible expansion in the future. Should I use web services/WCF? RIA Services? Remoting? Or something else. What have people used in the past and what do you recommend? Thanks

• What can't I build in Silverlight?

  - by Refracted Paladin

  First, I know that Silverlight needs to be embedded in a website, usually an asp page. I understand I need a delivery boy. My question is this; What types of apps/projects are so filled with technological hurdles as to make them ridiculous to do in Silverlight versus ASP.net? I know that with perseverance and flexibility I can probably make EVERY app in Silverlight, in some version or another, but which ones would be blatantly simple in, say ASP.net(or even WPF) but quite complicated in Silverlight? Basically what I am asking is if there is any reason I shouldn't consider Silverlight my first stop for every problem, obvious exceptions not with standing(a service or console). For me specifically, at this point, I am only building in house apps.

• WF4 - Display workflow design in asp.net and highlight an activity

  - by jikan_the_useless

  i need to display current status of a document approval workflow task in asp.net web page with a specific activity highlighted. i have seen the visual workflow tracker example (in wf&wcf samples) but i have two issues, 1-i have to render workflow in asp.net not in a wpf app. 2-i don't need to display current status with workflow running, all activities that need to highlighted are the one that require user input. e.g. "waiting for approval from department head" etc. if i could just convert the workflow xaml to jpg after highlighting a specific activity by activity id that created a bookmark and waiting to resume the bookmark it would do the work.

• What should Java programmer learn?

  - by Dieter

  Hi, I code only for 3 years now, I came thru C/C++, Delphi, SQL, VBA but I mostly code in Java. I do 90% GUIs, atm with Java swing. But time changes, so I have few questions : Should I switch to web development from GUIs? If GUIs, is C# and WPF suitable ? Should I learn .NET (C#,asp.net) or continue with Java (learn Spring, hibernate, JSP, JSF, JPA) ? What is faster to learn? Finish Java or start .NET Should I really consider using something other than Java/.NET ? Think of job opportunities. Thanx

• Disabling Alt-F4 on a Win Forms NotifyIcon

  - by Jippers

  I am using a NotifyIcon from Win Forms to make a systray icon for my C# application. I have a bug where if the user right clicks the icon for the context menu, they can press Alt-F4 and the icon will disappear from the tray, but the Main WPF application is still running. This is especially a problem when they have "minimized to systray" and the only control of the application is now gone. Anyone know how to handle this specificially on the systray? I've looked at the NotifyIcon documentation and there isn't anything relating to keypress events.

• Resharper doesn't play well with XAML?

  - by John Weldon

  I've been noticing a pattern with ReSharper (both 4.5 and 5). Very often (almost always) when I have solution-wide analysis turned on, and WPF code in my solution, ReSharper will mark a number of the .xaml.cs files as being broken. When I navigate to the file, sometimes it magically updates and displays no errors, and other times I have to open other files that are not being correctly read and close them again to force resharper to correctly analyze them. I assume it has something to do with the temporary .cs code that is generated with XAML, but does anyone know why this is actually happening, and if there is a work around? Should I just file a bug report with JetBrains? Does anyone else experience this?

• WCF performance improvements

  - by Burt

  I am developing a WPF application that talks to a server via WCF services over the internet. After profiling the application I noticed a lot of time is being taking up by creating the appropriate WCF client proxy and making the call to the server. The code on the server is optimised and doesn't take any time to run yet I am still seeing a 1.5 second delay from when a service is invloked to it returning to the client. A few points to give a bit of background: I am using the ASP.Net membership for security I will eventually hook into the same server side code through a website I would eventually like to have offline support in the application I really need to nail the performance early though as if the app is taking a couple of seconds to come back it is too long for what I am trying to do. Can anyone suggest performance tips that will help me please?
