  • It's Here! Visual Studio 2010 and ASP.NET 4.0 Ship

    Today Microsoft released Visual Studio 2010 and ASP.NET 4.0. I've been using the RC version of Visual Studio 2010 quite a bit for the past couple of months and have really grown to like it. It has a host of features and enhancements that improve developer productivity, from improved IntelliSense to better multiple monitor support. Plus there's something about the user experience that, to me, makes it feel better than Visual Studio 2008. I don't know if it's the new blue color motif or what, but the IDE seems more modern looking and more responsive to my mouse movements and other input. Anyway, if you've not yet downloaded Visual Studio 2010 and ASP.NET 4.0, why not? As with previous versions of Visual Studio there's a free Express Edition and VS2010 and ASP.NET 4.0 runs side-by-side with earlier versions of Visual Studio and ASP.NET. And with Visual Studio 2010's multi-targeting you can even use VS2010 as your development editor for ASP.NET 2.0 and ASP.NET 3.5 web applications. (Although be forewarned if you have multiple developers working on the application that the project files in VS2010 and earlier versions of Visual Studio differ.) This week's article on 4Guys explores my favorite new features of Visual Studio 2010. Here's an excerpt: The Visual Studio 2010 user experience is noticeably different than with previous versions. Some of the changes are cosmetic - gone is the decades-old red and orange color scheme, having been replaced with blues and purples - while others are more substantial. For instance, the Visual Studio 2010 shell was rewritten from the ground up to use Microsoft's Windows Presentation Foundation (WPF). In addition to an updated user experience, Visual Studio introduces an array of new features designed to improve developer productivity. There are new tools for searching for files, types, and class members; it's now easier than ever to use IntelliSense; the Toolbox can be searched using the keyboard; and you can use a single editor - Visual Studio 2010 - to work on. This article explores some of the new features in Visual Studio 2010. It is not meant to be an exhaustive list, but rather highlights those features that I, as an ASP.NET developer, find most useful in my line of work. Read on to learn more! And, in closing, here are some helpful VS2010 and ASP.NET 4.0 links: One click installation for ASP.NET 4.0, Visual Web Developer 2010, .NET Framework 4.0, and ASP.NET MVC 2 Eight Quick Hit videos showing some of the cool new VS2010 features VS2010 and ASP.NET 4.0 Release Announcement with some great info/links from none other than Scott Guthrie Happy Programming!Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Applications result affected by another running application.

    - by Jamie Keeling
    This is a follow on from my previous question although this is about something else. I've been having a problem where for some reason my message that I pass from one process to another only displays the first letter, in this case "M". My application is based on a MSDN sample so to make sure I hadn't missed something I create a separate solution, added the MSDN sample (without any changes for my needs) and unsurprisingly it works fine. Now for the weird bit, when I run the MSDN sample running (as in debugging) and have my own application running, the text prints out fine without any problems. The second I run my on its own without the original MSDN sample being open, and it fails to work and only shows an "M". I've looked in the debugger and don't seem to notice anything suspicious (it's a slightly dated picture, I've fixed the data type inconsistency). Can anyone provide a solution for this? I've never encountered anything like this before. To look at my source code it's easier to just look at the link I posted at the top of the question, there's no point in me posting it twice. Thank you for any help.

  • How can I create different DLLs in one project?

    - by jaloplo
    I have a question I don't know if it can be solved. I have one C# project on Visual Studio 2005 and I want to create different DLL names depending on a preprocessor constant. What I have in this moment is the preprocessor constant, two snk files and two assembly's guid. I also create two configurations (Debug and Debug Preprocessor) and they compile perfectly using the snk and guid appropiate. #if PREPROCESSOR_CONSTANT [assembly: AssemblyTitle("MyLibraryConstant")] [assembly: AssemblyProduct("MyLibraryConstant")] #else [assembly: AssemblyTitle("MyLibrary")] [assembly: AssemblyProduct("MyLibrary")] #endif Now, I have to put the two assemblies into the GAC. The first assembly is added without problems but the second isn't. What can I do to create two or more different assemblies from one Visual Studio project? It's possible that I forgot to include a new line on "AssemblyInfo.cs" to change the DLL name depending on the preprocessor constant?

  • Thread Management Object

    - by Gusdor
    I feel rather foolish as this is just a short question. I was reading about a bunch of thread management helper classes in .net, specifically one that aids the storage of threads to help a service manager object automatically invoke delegates onto the subscribing thread. I'm pretty sure it had something to do with creating dispatchers. Totally forgotten the name, can't find it :( Anyone know what I'm talking about?

  • Should I auto-increment the assembly version when I build my software?

    - by rwmnau
    In Visual Studio 2003, you could easily set your project assembly to auto-increment every time you built it, but with Visual Studio 2005, this functionality was removed. You can still auto-increment your assembly version on every build, but it's a complicated custom build step instead of an integrated feature. I'm not sure why this was removed, but here's a question I should have asked a while ago - Should I be using a workaround to continue to auto-increment when I build, or is there a good reason to stop doing this, in favor of manually incrementing? Since Microsoft removed it from VS, perhaps there's a good reason, and I'm wondering if anybody knows it.

  • Suggestions on including free database products to include in an application - SQL Server Express or

    - by superartsy
    I am working on an enterprise level product that is designed around SQL Server Express and specifically its features (views, concurrent users, stored procedures, CASE and IF statements). Though we don't use any advanced SQL Server features, the database size limit of 4GB in the Express edition may up being a limitation. A work-around is that customers can move to more full-featured versions of SQL Server. The problem is that SQL Server Express deployment is not easy, and the installer size is huge. This is a major drawback for someone looking to try our product. You don't want end-users to not buy a product because the download is huge. Does anyone have any recommendations of a database that has a smaller footprint but all the features of Express and which can be migrated to express?

  • Visual Studio 2010/2012 Context Menus and a Keyboard

    - by SergeyPopov
    As a software developer, I spend a lot of time using Visual Studio. I have to say that I completely satisfied with Visual Studio generally. Nevertheless, sometimes Visual Studio starts annoying me. One issue which poisoned my existence for a long time is that context menu behavior in VS2010 is a little different than it was in VS2005/2008. Unfortunately, in VS2012 this behavior remains the same as in VS2010. So, what is the issue? Working with Visual Studio, I use the keyboard in most cases. I also use the Apps key on the keyboard to open context menus in the code editor. Moreover, long time ago I am got used to using some key sequences, and press the keys without even thinking. In VS2008, a mouse pointer position didn’t affect context menu navigation if I used the keyboard. Every time I opened a context menu I was sure that, for example, the "Apps, Down, Down, Enter, Up, Enter" key sequence always invoke "Organize Usings > Remove and Sort" function. But in VS2010, this behavior has been changed. If a mouse pointer is located over an opened context menu, the menu item under the mouse pointer becomes selected immediately! So, now the "Apps, Down, Down, Enter, Up, Enter" key sequence will not lead to expected results all the time. In some cases, the result may be a little scary. If you are using Visual SVN extension, this key sequence may invoke "Revert whole file" function. Of course, this is not a fatal problem because "Undo" function restores all the changes, but this behavior strongly annoys me. In Visual Studio 2012, context menu behavior is a little different than in VS2010, but a mouse pointer position still affects the keyboard navigation in the context menu, and this behavior is still annoying. I tried to find the way how to change this behavior, but I didn’t manage to find the answer quickly. Then I decided to go right though, so I wrote a small utility which fixes this issue. This utility watches for Apps key, and if the key is pressed in Visual Studio, the utility moves the mouse pointer to the top of the screen before opening the context menu. You can find binaries and the source code of this utility here: http://code.google.com/p/vs-ctx-menu-fix/downloads/list This utility works fine in Windows 7 and Windows 8 x64. I wrote the first version in January, 2011; now I just added Visual Studio 2012 support. I hope you will find this utility useful! :)

  • Do Portable Class Libraries work with .net 3.5?

    - by Eric
    I am running Windows 8 and have both Visual Studio 2010 Ultimate w/sp1 and Visual Studio 2012 Ultimate and I am trying to create a Portable Class Library that supports .net 3.5 and greater. When I first try to create a PCL I get a screen like this: I noticed that .net 3.5 is not in the list so I clicked on "Install additional frameworks" and found a Targeting Pack for version 3.5. But when I download and run "dotnetfx35setup.exe" nothing happens. And when I go back into VS and try to create a new Portable Class Library, it lists the same target frameworks as before. I have also turned on the Windows Features for .NET Framework 3.5 and am now out of ideas. Here is a screen shot in case I missed something else. Thanks,

  • JVM memory management & garbage collection book?

    - by Max
    Hi. Could anyone advice a book (or any other source) that would thoroughly reveal internals of JVM memory management & garbage collection (optimization, work, circular references, pecularities, discussions for various JVM impls...)? [What I've found so far are separate articles devoted to various aspects but no weighty tome :). Some good materials for Hotspot implementation are here. ] Thanks a lot for any advice you give.

  • Using DirectX Effect11 with Visual Studio 2012

    - by l3utterfly
    I recently updated to Visual Studio 2012 Ultimate. I was programming previously with DirectX 11 June 2010 SDK and want to continue to do so using Visual Studio 2012. However, I discovered that VS2012 comes with its own DirectX SDK (in Windows Kit 8.0) and I've been trying to migrate my code using the newer versions of d3d11. Everything went fine until I try to use effect files in my project (.fx files). I had to compile the Effects11 Sample in the DirectX SDK using VS2012 and link the lib file in my project. That went fine too. However, when I compile my project the function D3DX11CreateEffectFromMemory returns a E_NOINTERFACE error (no such interface is supported). Can anyone tell me why is that? Note that I'm using the d3d11.lib from the Windows Kit and the d3dx11.lib from the DirectX SDK. Perhaps I shouldn't mix them? However, everything else works fine when I mix them, except for the effect file creation. Any help would be appreciated. P.S. I don't know if this is helpful but just so you know, if I add an additional library directory in the project settings of "DirectXSDKInstallPath\lib\x86\" it works. Why is that? Does it mean I'm using the older version of the libraries? This will give a ton of warnings about redefined headers in winerror.h

  • Unable to import Eclipse project to Android studio

    - by Binoy Babu
    Whenever I try to import my Eclipse project to Android Studio I get the following error : You are using an old, unsupported version of Gradle. Please use version 1.8 or greater. Please point to a supported Gradle version in the project's Gradle settings or in the project's Gradle wrapper (if applicable.) Consult IDE log for more details (Help | Show Log) Im using Android Studio 0.3 and Ubuntu, I also tried it on a Windows 8 box with fresh install but getting the same error. I'm using default gradle wrapper and I tried checking and unchecking auto import option. Is this a bug? How can I get around it. How do I update gradle to 1.8 or check the current gradle version?

  • Source Control - XCode - Visual Studio 2005/2008 / 2010

    - by Mick Walker
    My apologies if this has been asked before, I wasnt quite sure if this question should be asked on a programming forum, as it more relates to programming environment than a particular technology, so please accept my (double) appologies if I am posting this in the wrong place, my logic in this case was if it effects the code I write, then this is the place for it. At home, I do a lot of my development on a Mac Pro, I do development for the Mac, iPhone and Windows on this machine (Xcode & Visual Studio - (multiple versions installed in bootcamp, but generally I run it via Parallels)). When visiting a client, I have a similar setup, but on my MacBook Pro. What I want is a source control solution to install on the Mac Pro, that will support both XCode and multiple versions of visual studio, so that when I visit a client, I can simply grab the latest copy from source control via the MacBook Pro. Whilst visiting the client, he / she may suggest changes, and minor ones I would tend to make on site, so I need the ability to merge any modified code back into the trunk of the project / solution when I return home. At the moment, I am using no source control at all, and rely on simply coping folders and overwriting them when I return from a client- thats my 'merge'!!! I was wondering if anyone had any ideas of a source provider I could use, which would support both Windows and Mac development environments, and is cheap (free would be better).

  • Getting Visual Studio macros in console app

    - by Paul Steckler
    In a Visual Studio extension, you can get the default include paths for all projects with C# code like: String dirs = dte2.get_Properties("Projects", "VCDirectories"); where dte2 is the Visual Studio application object. Usually, those directories contain macros like $(INCLUDE). You can expand those macros by looking at dte2.Solution.Projects, finding the relevant project in that collection; from the project, look at project.Configurations, find the relevant configuration, and call its Evaluate method. In VS2005/VS2008, there's a .vssettings file that contains the VCDirectories. In VS2010, there's a property sheet with the same information. A console application can just parse those files -- great. But how can you expand the macros? As a first step, I tried instantiating a VCProjectEngine object in a console app, but that just resulted in a COM failure. So I don't know how to instantiate a VCProject object in order to follow the same strategy I used in a VS extension. Where are the macro bindings stored?

  • Visual Studio 2008 IDE freezes/crashes when opening .aspx file with css included

    - by Kai
    I have read a lot of questions about Visual Studio 2008 crashing on viewing some source files. However, I still can't fix this problem. Visual Studio (SP1) runs fine until I try and view .aspx source files with the lines <style type="text/css"> </stlye> anywhere in them, upon which it freezes (i.e is totally unresponsive) and I have to use the task manager to shut it down. I have systematically deleted and re-included all other code and it comes down to these two lines, which is very confusing. Sometimes it happens as soon as the lines are added, sometimes it doesn't freeze until I build the solution with any of the problem pages open. I can add external style sheets, and it only started recently. I tried the event viewer logs but I don't really understand how to use them to find out about this. I had Resharper 4.5 installed and have since uninstalled it, and do not have anything else installed. Is there any way I can a) find out what's happening, b) fix it without reinstalling vs?

  • Assembly installed into the GAC not showing up in Visual Studio

    - by yodaj007
    This sounds related to this question, but they aren't the same thing. That question had no assemblies showing up. Mine has everything except the specific one I installed. I'm hoping someone has a solution to this... am I doing something wrong? Or did I find some bug in VS? I am using Visual Studio 2010 Professional Beta 2 on Windows 7 Ultimate. I just downloaded Rhino Mocks and decided to install it into the GAC using the command-line utility GACUTIL. I then rebooted. Here you can see the assembly in my GAC (click to enlarge): And here is the list of assemblies available to me in Visual Studio: Here is the command prompt where I installed it, and then confirmed it: C:\Users\jason\Downloads>gacutil -i Rhino.Mocks.dll Microsoft (R) .NET Global Assembly Cache Utility.

  • Visual Studio 2008 / ASP.NET 3.5 / C# -- issues with intellisense, references, and builds

    - by goober
    Hey all, Hoping you can help me -- the strangest thing seems to have happened with my VS install. System config: Windows 7 Pro x64, Visual Studio 2008 SP1, C#, ASP.NET 3.5. I have two web site projects in a solution. I am referencing NUnit / NHibernate (did this by right-clicking on the project and selecting "Add Reference". I've done this for several projects in the past). Things were working fine but recently stopped working and I can't figure out why. Intellisense completely disappears for any files in my App_Code directory, and none of the references are recognized (they are recognized by any file in the root directory of the web site project. Additionally, pretty simple commands like the following (in Page_Load) fail (assume TextBox1 is definitely an element on the page): if (Page.IsPostBack) { str test1; test1 = TextBox1.Text; } It says that all the page elements are null or that it can't access them. At first I thought it was me, but due to the combination of issues, it seems to be Visual Studio itself. I've tried clearing the temp directories & rebuilding the solution. I've also tried tools -- options -- text editor settings to ensure intellisense is turned on. I'd appreciate any help you can give! Thanks, Sean

  • Visual Studio 2010 / ASP.NET MVC / Publish

    - by SevenCentral
    I just did a clean install on Windows 7 x64 Professional with the final release of Visual Studio 2010 Premium. In order to duplicate what I'm experiencing do the following in: Create a new ASP.NET MVC 2 Web Application Right click the project and select Properties On the Web tab, select "Use Local IIS Web Server" Click on Create Virtual Directory Save all Unload the project Edit the project file Change MvcBuildViews to true Save all Reload project Right click the project and select Publish Choose the file system publish method Enter a target location Choose Delete all existing files Select Publish Right click the project Select Publish Each time I do the above I get the following errror: "It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level..." The error originates from obj\debug\package\packagetmp\web.config, relative to the project directory. I can repeat this all day long with any MVC 2 project I've built. In order to fix this problem, I need to set MvcBuildViews to false in the project file. That's not really an option. This wasn't a problem in Visual Studio 2008 and it seems to be an issue with the way the Publish command stages files beneath the project directory. Can anyone else duplicate this error? Is this a bug or by design? Is there a fix, workaround, etc...? Thanks.

  • Destroy process-less console windows left by Visual Studio debug sessions

    - by jon hanson
    A known bug with security update KB978037 can occur with Visual Studio 2003 (and 2008) where sometimes if you restart a debugging session on a console app then the console window doesn't get closed even though the owner process no longer exists. The problem is discussed further here: http://stackoverflow.com/questions/2402875/visual-studio-debug-console-sometimes-stays-open-and-is-impossible-to-close These zombie windows then can not be closed via the Taskbar or via the TaskManager, and typically require a power off/on to get rid of them. Over the period of even a single day you can accumulate quite a few of them, which clog up your TaskBar and are generally annoying. I thought I would knock up a simple C++ Win32 utility to attempt to call DestroyWindow() on these windows by passing the windows handle as a cmd-line argument and converting it to a HWND. I'm converting the handle from a string by parsing it as a DWORD then casting the DWORD to a HWND. This appears to be working as if I call GetWindowInfo() on the handle it succeeds. However calling DestroyWindow() on the handle fails with error 5 (access denied), presumably because the caller process (i.e. my app) doesn't own the window in question. Any ideas as to how I might get rid of the zombie windows, either via the above approach or any other alternative short of rebooting? I'm in a corporate environment so installing/uninstalling updates/service-packs etc isn't an option.

  • Connecting to database on web host in Visual Studio

    - by Anders Svensson
    I have a web site developed locally with a local Sql Server database. I also have a web host that provides one Sql Server database for my site. Now I want to deploy the application, and I would like to be able to manage the remote database from the Server Explorer in Visual Studio. I have the connection string used in the application, which works fine for adding, say, a datasource to a control etc. But I don't know if there's any way to use it to connect the database inside the Server Explorer so that I can add tables etc. I have read that you're supposed to be able to this instead of using the Sql Server Management Studio, but I have'nt read anything about how to connect to the remote database in it. What I have tried so far is this: I have selected Add database in Server Explorer. This brings up first a dialog where I choose Sql Server. And then I get a dialog where I can set Server name (which I tried using the ip address in the connection string below), and Authentication (where I chose Sql Server Authentication, with the user id and password from below). But when I test the connection it fails. Here's the connection string, which works fine when used for datasources in the application (obviously with different user name and password): Any help appreciated!
