• Visual Studio 2010 haunted keyboard

  - by Ryan

  It seems the haunted keyboard is back in VS2010 ... after working on a web application for a short while I find that some keys just don't work, or are behaving like certain keys are stuck. This is only in VS, and I am definitely not triggering any keyboard changes in VS or Windows (I have disabled that in Windows) and I have reset my environment settings several times. Aargh! This is so frustrating ... anyone else getting this problem? Is there a solution?

• Visual Studio Setup - why is solution explorer on the right?

  - by amelvin

  Every time I install VS (whichever version going back years) it installs with the Solution Explorer on the right. Now as most UIs have the navigation in a left hand column (and at the top of the viewport) and the content to the right of this navigation this always seems wrong to me. So I drag the solution explorer to the left of the screen and dock it there. But I've never seen another developer do this. Considering how most programmers usually like to customize their environment, adding their favourite text editor, browser, plug-ins, greasemonkey scripts etc why do Visual Studio developers never seem to make this simple UI change? Does anyone else do this or am I just screaming in the dark?

• Visual Studio Express 2012 - Moving items to tab control loses actions

  - by JohnP

  VS 2012 Express on Windows 7 Professional, this was pre SP1 install. I have a windows form that I had several elements (Listboxes, buttons, text and labels), with some actions associated with changing indices on the list boxes and of course the button actions. I decided I wanted to add a tab control to enable a second tab with a different feature set, so I copied/cut/pasted all of the original items to a tab control that I added. When I did this, all of the elements lost their click action in the events window. I had to go and re-associate all of them. Is this a normal behavior/known issue, or is there some method to move controls that I am not aware of?

• Running CopySourceAsHtml Add-in under Visual Studio 2010

  - by Marko Apfel

  Until now CopySourceAsHtml only supports Visual  Studio 2008 out of the box. But it is no problem to pimp up the config-file for supporting Visual Studio 2010. Copy all three files to "%userprofile%\Documents\Visual Studio 2010\Addins" Open CopySourceAsHtml.AddIn in a text editor and change both lines with <Version>9.0</Version> to <Version>10.0</Version> Run Visual Studio 2010 and CopySourceAsHtml works fine

• Visual Studio 2010 locking referenced Assembly

  - by cunningdave

  I have a sandbox app that is built from the simple WPF Application template. This sandbox references an assembly that I am also building which contains the definition of a UserControl (WPF). I am instantiating this user control in the sandbox, to test the control's behaviour. The point of all this is to speed up development. This worked fine, but recently the .Vshost.exe paired with the sandbox process won't shut down. This prevents me from recompiling the Controls library, though ironically I can recompile the sandbox application. I can't kill the vshost process with Task Manager... only restarting VS2010 will clear it out. But every time I run the application from VS, the process just hangs there, blocking my workflow. I'm at a loss. Any ideas what could be causing this? Or does someone have any proposed workaround (mega-kill switch, perhaps?)

• VS2010 asking to upgrade SIlverlight??

  - by Lu10ntDan

  I'm running the absolute latest versions of Silverlight and Visual Studio 2010 Professional and built a solution that contained a WPF project. From there, I added a SketchFlow project (based on Blend 4 RC) and I can run each project within the solution just fine by setting whenever I switch between them as startup projects. From there, I added a Silverlight 4 Business Application (taking all the defaults), and when simply trying to set that as the startup project and running it, VS2010 is giving me the following error after trying to open a web page: Line: 56 (in file TestPage.aspx) Error: Unhandled Error in Silverlight Application Code: 8001 Category: InitializeError Message: Upgrade required If I choose not to debug, I get the Silverlight page saying "This page requires a more recent version of Silverlight"! Clicking "Install Now" on the popup window brings me to Mirosoft's Silverlight page where I see: "The version of Silverlight originally requested is not available. You can get a supported version from this page. This Web browser or operating system may not be compatible with Silverlight. Please review the system requirements and, if you wish to proceed, choose the link for your operating system." If I choose to upgrade anyway, I'm told that I'm running the latest version of Silverlight available. What the heck? I'm running the final versions of VS2010 Pro, Silverlight 4, and the latest version of Expression Blend 4 (RC). Why can't VS2010 run this default Silverlight Business App? Any ideas? Please?? Thanks, Lu10ntDn PS. This is on Windows 7 with UAC turned off, and ALL latest Windows Updates installed.

• How to reflect over T to build an expression tree for a query?

  - by Alex

  Hi all, I'm trying to build a generic class to work with entities from EF. This class talks to repositories, but it's this class that creates the expressions sent to the repositories. Anyway, I'm just trying to implement one virtual method that will act as a base for common querying. Specifically, it will accept a an int and it only needs to perform a query over the primary key of the entity in question. I've been screwing around with it and I've built a reflection which may or may not work. I say that because I get a NotSupportedException with a message of LINQ to Entities does not recognize the method 'System.Object GetValue(System.Object, System.Object[])' method, and this method cannot be translated into a store expression. So then I tried another approach and it produced the same exception but with the error of The LINQ expression node type 'ArrayIndex' is not supported in LINQ to Entities. I know it's because EF will not parse the expression the way L2S will. Anyway, I'm hopping someone with a bit more experience can point me into the right direction on this. I'm posting the entire class with both attempts I've made. public class Provider<T> where T : class { protected readonly Repository<T> Repository = null; private readonly string TEntityName = typeof(T).Name; [Inject] public Provider( Repository<T> Repository) { this.Repository = Repository; } public virtual void Add( T TEntity) { this.Repository.Insert(TEntity); } public virtual T Get( int PrimaryKey) { // The LINQ expression node type 'ArrayIndex' is not supported in // LINQ to Entities. return this.Repository.Select( t => (((int)(t as EntityObject).EntityKey.EntityKeyValues[0].Value) == PrimaryKey)).Single(); // LINQ to Entities does not recognize the method // 'System.Object GetValue(System.Object, System.Object[])' method, // and this method cannot be translated into a store expression. return this.Repository.Select( t => (((int)t.GetType().GetProperties().Single( p => (p.Name == (this.TEntityName + "Id"))).GetValue(t, null)) == PrimaryKey)).Single(); } public virtual IList<T> GetAll() { return this.Repository.Select().ToList(); } protected virtual void Save() { this.Repository.Update(); } }

• Blend "Window is not supported in a WPF Project"

  - by Andy Dent

  I am having a frustrating time with Blend reporting "Window is not supported in a Windows Presentation Foundation (WPF) project." due to unbuildable configurations but can't quite work out how to mangle my way out of it. I've worked out it is probably due to my trying to have a single solution with x86 and x64 configurations. There is no way to tell Blend 2 which is the active Solution Configuration and active Solution Platform. I think it's a bit of a weakness in the configuration system, or maybe the way I've set things up, but I have Debug64 and Debug solution configurations one of each is used with the platform x86 and x64. I also think it's a simple sorting problem - x64 comes before x86 and Debug comes before Debug64 so Blend ends up with an unbuildable config of Debug with x64. When I choose the combination of Debug and x64 in VS, its XAML editor can't load either. The solution is a moderately complex one - there's a pure Win32 DLL, C++/CLI Model project and two other WPF assemblies used by the main WPF project. UPDATE I have ripped all the x64 config out of my solution and rebuilt everything with no effect. I then uninstalled Blend 2 and installed Blend 3 - it doesn't like things either. The Visual Studio XAML editor is still very happy as is the program building and running. (echoes of strangled scream of frustration from oz)

• Why is my Output distorted after encoding with Expression Encoder?

  - by WernerCD

  I'm a "n00b" when it comes to re-encoding files. I'm trying to re-encode an AVI into a silverlight container via Encoding Video using Expression Encoder 4.0. As you can see in the video, the left is the input and it looks/sounds fine. The right is the output and it... doesn't. I'm unsure of where to go from here. I'm not sure why the output is jacked up, since the input looks fine. Input Video properties: AVI 2.49GB 22:34 809x605 Video: TSCC 809x605 15fps [Stream 00] Audio: PCM 22050Hz mono 352kbps [Stream 01] Choice of output doesn't seem to matter, they all end up distorted like the picture shows.

• Windows Phone 7 development: first impressions

  - by DigiMortal

  After hard week in work I got some free time to play with Windows Phone 7 CTP developer tools. Although my first test application is still unfinished I think it is good moment to share my first experiences to you. In this posting I will give you quick overview of Windows Phone 7 developer tools from developer perspective. If you are familiar with Visual Studio 2010 then you will feel comfortable because Windows Phone 7 CTP developer tools base on Visual Studio 2010 Express. Project templates There are five project templates available. Three of them are based on Silverlight and two on XNA Game Studio: Windows Phone Application (Silverlight) Windows Phone List Application (Silverlight) Windows Phone Class Library (Silverlight) Windows Phone Game (XNA Game Studio) Windows Phone Game Library (XNA Game Studio) Currently I am writing to test applications. One of them is based on Windows Phone Application and the other on Windows Phone List Application project template. After creating these projects you see the following views in Visual Studio. Windows Phone Application. Click on image to enlarge. Windows Phone List Application. Click on image to enlarge.  I suggest you to use some of these templates to get started more easily. Windows Phone 7 emulator You can run your Windows Phone 7 applications on Windows Phone 7 emulator that comes with developer tools CTP. If you run your application then emulator is started automatically and you can try out how your application works in phone-like emulator. You can see screenshot of emulator on right. Currently there is opened Windows Phone List Application as it is created by default. Click on image to enlarge it. Emulator is a little bit slow and uncomfortable but it works pretty well. This far I have caused only couple of crashes during my experiments. In these cases emulator works but Visual Studio gets stuck because it cannot communicate with emulator. One important note. Emulator is based on virtual machine although you can see only phone screen and options toolbar. If you want to run emulator you must close all virtual machines running on your machine and run Visual Studio 2010 as administrator. Once you run emulator you can keep it open because you can stop your application in Visual Studio, modify, compile and re-deploy it without restarting emulator. Designing user interfaces You can design user interface of your application in Visual Studio. When you open XAML-files it is displayed in window with two panels. Left panel shows you device screen and works as visual design environment while right panel shows you XAML mark-up and let’s you modify XML if you need it. As it is one of my very first Silverlight applications I felt more comfortable with XAML editor because property names in property boxes of visual designer confused me a little bit. Designer panel is not very good because it is visually hard to follow. It has black background that makes dark borders of controls very hard to see. If you have monitor with very high contrast then it is may be not a real problem. I have usual monitor and I have problem. :) Putting controls on design surface, dragging and resizing them is also pretty painful. Some controls are drawn correctly but for some controls you have to set width and height in XML so they can be resized. After some practicing it is not so annoying anymore. On the right you can see toolbox with some controllers. This is all you get out of the box. But it is sufficient to get started. After getting some experiences you can create your own controls or use existing ones from other vendors or developers. If it is your first time to do stuff with Silverlight then keep Google open – you need it hard. After getting over the first shock you get the point very quickly and start developing at normal speed. :) Writing source code Writing source code is the most familiar part of this action. Good old Visual Studio code editor with all nice features it has. But here you get also some surprises: The anatomy of Silverlight controls is a little bit different than the one of user controls in web and forms projects. Windows Phone 7 doesn’t run on full version of Windows (I bet it is some version of Windows CE or something like this) then there is less system classes you can use. Some familiar classes have less methods that in full version of .NET Framework and in these cases you have to write all the code by yourself or find libraries or source code from somewhere. These problems are really not so much problems than limitations and you get easily over them. Conclusion Windows Phone 7 CTP developer tools help you do a lot of things on Windows Phone 7. Although I expected better performance from tools I think that current performance is not a problem. This far my first test project is going very well and Google has answer for almost every question. Windows Phone 7 is mobile device and therefore it has less hardware resources than desktop computers. This is why toolset is so limited. The more you need memory the more slower is device and as you may guess it needs the more battery. If you are writing apps for mobile devices then make your best to get your application use as few resources as possible and act as fast as possible.

• Visual Studio 2010 Can no longer build .NET v3.5

  - by Adam Driscoll

  I have a 2010 project that is targeting .NET v3.5. Inexplicably I can no longer build v3.5 projects. The project doesn't have ANY references added. It won't even let me add a reference to System.Core as it is added by the 'build system'. warning CS1685: The predefined type 'System.Func' is defined in multiple assemblies in the global alias; using definition from 'c:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll' IFilter.cs(82,49): error CS0433: The type 'System.Func' exists in both 'c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.5\System.Core.dll' and 'c:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll' Looks like something is grabbing onto 4.0 but I'm not quite sure how to fix it. Any one else run into this? Coworker had this same issue. It took a reinstall of Windows to correct the problem I've opened a bug on this one: https://connect.microsoft.com/VisualStudio/feedback/details/558245/warning-cs1685-when-compiling-a-v3-5-net-application-in-visual-studio-2010 If the compiler is set to verbose I see this: FrameworkPathOverride = C:\Windows\Microsoft.NET\Framework\v4.0.30319 which is defined as: Specifies the location of mscorlib.dll and microsoft.visualbasic.dll. This parameter is equivalent to the /sdkpath switch of the vbc.exe compiler. Some other interesting tidbits: I've created a new project all together and cannot build v3.5 at all. I can build 2.0, 3.0, 3.5 Client Profile, 4.0 and 4.0 Client Profile with no problem. VB.NET can build v3.5 but C# cannot. I've tried a reinstall of .NET 3.5, 4.0 and Visual Studio 2010 with no success. Visual Studio debug logs shown nothing interesting and Safe Mode does not work. Trying to avoid a Windows reinstall...

• C++ errors not shown in Visual Studio C# project

  - by Diana

  I have in Visual Studio 2008 a .NET 3.5 C# project that uses a dll compiled from a C# project (let's call it dll A). Dll A is using on his turn some C++ libraries. The problem is that when I encounter an error while calling objects from dll A, the application just closes, without showing any error. But I need to know what's the problem, I cannot just guess and go blind all along the project with this... I checked Window's event log, could not find anything. I checked the settings of throwing errors in Visual Studio, in menu Debug - Exceptions, all of them are checked (including C++ exceptions), so, any errors should be thrown. My code looks something like this: tessnet2.Tesseract tessocr = new tessnet2.Tesseract(); tessocr.Init(@"s:\temp\tessdata", "eng", false); tessocr.GetThresholdedImage(bmp, Rectangle.Empty).Save("s:\\temp\\" + Guid.NewGuid().ToString() + ".bmp"); List<tessnet2.Word> words = ocr.DoOCR(bmp, "eng"); //App exits at this line If I put in my code something like int x = Convert.ToInt32("test"); this should throw an error. And it throws, and Visual Studio shows it. Does anyone having any idea why the errors are not being shown? Or where else could be registered? Any help is very appreciated! Thanks!

• Error building Visual Studio 2010 Silverlight 4 projects on Windows 7 with XP Mode

  I installed Visual Studio 2010 Beta 2 in an XP Mode VM on Windows 7. Then I created a trivial Silverlight 4 (beta) project and tried to build it. I get the following error: Error 1 The "ValidateXaml" task failed unexpectedly.

Anyone know how to fix it?

• Is there a library that can decompile a method into an Expression tree, with support for CLR 4.0?

  - by Daniel Earwicker

  Previous questions have asked if it is possible to turn compiled delegates into expression trees, for example: http://stackoverflow.com/questions/767733/converting-a-net-funct-to-a-net-expressionfunct The sane answers at the time were: It's possible, but very hard and there's no standard library solution. Use Reflector! But fortunately there are some greatly-insane/insanely-great people out there who like reverse engineering things, and they make difficult things easy for the rest of us. Clearly it is possible to decompile IL to C#, as Reflector does it, and so you could in principle instead target CLR 4.0 expression trees with support for all statement types. This is interesting because it wouldn't matter if the compiler's built-in special support for Expression<> lambdas is never extended to support building statement expression trees in the compiler. A library solution could fill the gap. We would then have a high-level starting point for writing aspect-like manipulations of code without having to mess with raw IL. As noted in the answers to the above linked question, there are some promising signs but I haven't succeeded in finding if there's been much progress since by searching. So has anyone finished this job, or got very far with it? Note: CLR 4.0 is now released. Time for another look-see.

• Visual Studio 2010 Professional - Problem Unit-Testing Web Services

  - by Ben

  Have created a very simple Web Service (asmx) in Visual Studio 2010 Professional, and am trying to use the auto-generated unit test cases. I get something that seems quite familiar on this site: The web site could not be configured correctly; getting ASP.NET process information failed. Requesting http://localhost:81/zfp/VSEnterpriseHelper.axd return an error: The remote server returned an error: (500) Internal Server Error. http://stackoverflow.com/questions/260432/500-error-running-visual-studio-asp-net-unit-test I have tried: 1. Running the tests on IIS rather than ASP.NET Development Server 2. Adding and then removing the XML fragment to my Web Service's .config file 3. Giving the MACHINE\ASPNET account Full control to the local folder My current questions: 1. Why am I being bothered with this instrumentation / code coverage DLL, when this doesn't seem to be something that ships with Visual Studio 2010 Professional? Is there any way I can turn it off? 2. I'm placing the node under in Web.config - is that the correct node? 3. Is it possible to bind to a web service without using the webby test attributes? I've seen other people advising making the Web Service as light-weight as possible. I'm trying to call it with jQuery / AJAX / JSON, so being able to debug the actual web service would be really helpful. Best wishes, Ben

• Visual Studio 2010: very slow web applications debugging!

  - by micha12

  I recently installed Visual Studio 2010 (Ultimate edition, final version released in April), and found that debugging a web application became very slow (2-3 times slower than in Visual Studio 2008)! I took the same web application and checked the speed of loading of one of its pages in VS 2008 and VS 2010, and compared the time it takes to load the page. I tested it using 2 approaches: 1) debugging under ASP.NET Development Server (by pressing the "Start" button) and 2) using ASP.NET Development Server without debugging (by using the "View in Browser" menu command). And I got the following results for Visual Studio 2008 and 2010. 1) ASP.NET Development Server withoud debugging ("View in Browser"): the speed of page loading is the same in VS 2008 and 2010. 2) Debugging under ASP.NET Development Server ("Start" button): in VS 2010 the page takes more time to load than in VS 2008 - VS 2010 debugging is 2-3 times slower than in VS 2008! 3) At the same time, when debugging a web application in VS 2008, it takes the same time to load the page compared to when using only the "View in Browser" command. That is, VS 2008 debugging does not introduce any overhead to page loading in the web browser! I wanted to make sure that other people have the same problem with slow debugging of web applications in VS 2010. Can this issue be solved by any means? BTW, I am using Windows XP SP3. Thank you.

• Visual Studio - Edit source code located in a database

  I am building something similar to Server Explorer for Apache CouchDB. One of the things necessary is to be able to edit CouchDB view definitions which in CouchDB are JavaScript functions. How can I trick Visual Studio into using my object to retrieve and save the content of the JavaScript function but still use the rest of it - I am happy with editor itself and have no intention of writing my own Editor/Language Service, etc. The latter would be much bigger effort than what this project warrants Edit After more digging I am still stuck. Here is what I know: IVsUIShellOpenDocument interface provides a method OpenStandardEditor which can be used to open the standard Visual Studio editor. As one of the parameters this method takes a Pointer to the IUnknown interface of the document data object. This object is supposed to implement several interfaces described in many places all over the MSDN. Visual Studio SDK also provides a 'sample' implementation of the document data object VsTextBufferClass. I can create an instance of this class and when I pass the pointer to the instance to the OpenStandardEditor I can see my editor and it seems to work ok. When I try to implement my own class implementing the same interfaces (IVsTextBuffer, VsTextBuffer, IVsTextLines) OpenStandardEditor method returns success, but VS bombs out on call editor.Show() with an access violation. My suspicion is that VsTextBufferClass also implements some other interface(s) but not in C# way but rather in the good old COM way. I just do not know which one(s). Any thoughts?

• How can I pass in a params of Expression<Func<T, object>> to a method?

  - by Pure.Krome

  Hi folks, I have the following two methods :- public static IQueryable<T> IncludeAssociations<T>(this IQueryable<T> source, params string[] associations) { ... } public static IQueryable<T> IncludeAssociations<T>(this IQueryable<T> source, params Expression<Func<T, object>>[] expressions) { ... } Now, when I try and pass in a params of Expression<Func<T, object>>[], it always calls the first method (the string[]' and of course, that value isNULL`) Eg. Expression<Func<Order, object>> x1 = x => x.User; Expression<Func<Order, object>> x2 = x => x.User.Passport; var foo = _orderRepo .Find() .IncludeAssociations(new {x1, x2} ) .ToList(); Can anyone see what I've done wrong? Why is it thinking my params are a string? Can I force the type, of the 2x variables?

• Upgrading from VS2008 Pro to VS2010 Pro without MSDN

  - by Richard Bysouth

  Hi I'm looking to upgrade from Visual Studio 2008 Pro to Visual Studio 2010 Pro without MSDN. On the MSDN US site there's pricing for Upgrade from Standard for $299. On the UK MSDN site however, the only options are to buy with MSDN for £484.99. Obviously a big difference in price there! I can't find any info as to what qualifies for the Upgrade from Standard - anyone know about this? Or whether it's available in the UK? thanks Richard
