• StyleCop SA1638

  - by niaher

  I am using StyleCop in VS2008. I get this error: SA1638: The file attribute in the file header's copyright tag must contain the name of the file. Here is my header. // <copyright file="AssemblyInfo.cs" company="company"> // Copyright (c) company. All rights reserved. // </copyright> // <author>me</author> // <email>[email protected]</email> // <date>2010-03-04</date> // <summary>blah blah.</summary> I suspect the problem is that my AssemblyInfo.cs is located inside the Properties folder. Any clues to how I can fix this warning without silencing StyleCop?

• ASP.NET Asynchronous Tasks - Worker Thread Not Releasing?

  - by user296752

  I am having an issue with testing asynchronous tasks in ASP.NET & IIS7. From what I have read, the worker thread should be released back into the thread pool while the I/O thread performs the async work, allowing ASP.NET to server other incoming requests. But when I simulate heavy load on the web application by making 20 simultaneous requests to a page (async.aspx) that performs long running async tasks, I am unable to browse to some other normal aspx page until the requests are just about done. Am I misunderstanding or missing something here? I am running Vista Biz x64, VS2008 + IIS7. I have the Async attribute applied to the Page directive.

• Launching my deployed my app gets "has stopped working" error. How do I debug this?

  - by Brad Mathews

  I deployed a VB.Net app and ran it and I get 'AppName has stopped working" "Windows is checking for a solution to the problem" along with a Cancel button under Windows 7. Under XP I am only getting the option to Send the error report to Microsoft or not. There is no apparent way to hook into a debugger. I am not getting any exception data. I have put msgboxes at the very start of my code and they are not hit so it is failing before any of my code is even executing. I have checked all dependencies that I can think of. I developed the app on VS2008 Windows 7 and deploying to Windows 7 and WinXP. I need some advice - how do I debug this? Thanks, Brad

• How to share WinForms and code between 2 projects

  - by Richard Bysouth

  Hi I have a working Windows Forms app (split into an EXE and a few DLLs). Now I've been asked to look at creating another app (MyAppLite) that has only a very small subset of the functionality. Think of it as similar to MS Word Viewer vs. MS Word. Everything that I need to build MyAppLite is contained in the main solution - essentially I need to use a couple of the WinForms and whatever bits in the DLLs they call into. What would be the best way to do this? I was thinking of creating another Project in my solution for MyAppLite, then adding the necessary source files as links (using Add Existing Item Add As Link in Solution Explorer). I definitely wouldn't want to maintain 2 copies of the source code. FYI it's a .NET 2.0 VB app, using VS2008. thanks Richard

• ASP.NET Deployment under IIS7/VS2010 as Web Application

  - by adchased

  I transformed my VS2008 ASP.NET Website to a "Web Application" today using VS2010. So now it's possible to build a Deployment Package. A Zip Package which can be direclty imported into IIS7. Usually I added a website in IIS7 called mydomain.com and put everything in its root dir. That worked. However, since I converted to an Web Application, this Application is added beneath my "Website container". Now I'm confused, this is how it actually looks now when I try to open the website: Browsing to mydomain.com says 404 ERROR. Browsing to mydomain.com/mydomain.com opens the actual website, but in a subfolder instead of the root directory. (The Application is named after the Domain) How to make this application the root of the website now? I want the application to run under the mydomain.com ROOT and not some subfolder. Thanks a lot!

• Entity Framework vs LINQ to SQL

  - by Chris Roberts

  Now that .NET v3.5 SP1 has been released (along with VS2008 SP1), we now have access to the .NET entity framework. My question is this. When trying to decide between using the Entity Framework and LINQ to SQL as an ORM, what's the difference? The way I understand it, the Entity Framework (when used with LINQ to Entities) is a 'big brother' to LINQ to SQL? If this is the case - what advantages does it have? What can it do that LINQ to SQL can't do on its own?

• Visual studio 2008 - Find in files : lists everything twice

  - by Aheho

  In VS2008, I have a web-site project. When I use find in files and search for a string, the find results window will list every occurence twice. What could be causing this? [EDIT] Below is the screen capture from VS. I was searching for the work CommissionBucketProductID within my website project. Notice that each line is returned twice. [EDIT2] In response to your questions. I am only searching within the project, not the whole solution. I currently don't have these files under VSS, although they were in the past.

• Error when running MSpec - how do I troubleshoot?

  - by Tomas Lycken

  I am following this guide to installing and using MSpec, but at the step where he runs MSpec for the first time, I get the following error: Could not load file or assembly 'file:///[...]\Nehemiah\Nehemiah.Specs\bin\Debug\Nehemiah.Specs.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded. I have - to my knowledge - done everything more or less exactly like he did up to this step, except where differences arise because he's using VS2008 and I'm using VS2010, and everything has worked so far. The project Nehemijah.Specs (and the entire solution) builds without problem, both in Visual Studio and on my build server, and I can't find anything useful in Event Viewer (although I might not be looking in the right place here...) What to do?

• LINQ to SQL Web Application Best Practices

  - by derek

  In my experience building web applications, I've always used a n-tier approach. A DAL that gets data from the db and populates the objects, and BLL that gets objects from the DAL and performs any business logic required on them, and the website that gets it's display data from the BLL. I've recently started learning LINQ, and most of the examples show the queries occurring right from the Web Application code-behinds(it's possible that I've only seen overly simplified examples). In the n-tier architectures, this was always seen as a big no-no. I'm a bit unsure of how to architect a new Web Application. I've been using the Server Explorer and dbml designer in VS2008 to create the dbml and object relationships. It seems a little unclear to me if the dbml would be considered the DAL layer, if the website should call methods within a BLL, which then would do the LINQ queries, etc. What are some general architecture best practices, or approaches to creating a Web Application solution using LINQ to SQL?

• C++ Project compiles as static lib, fails (linker error) as dynamic lib. why??

  - by Roey

  Hi All. I've a VS2008 native C++ project, that I wish to compile as a DLL. It only references one external library (log4cplus.lib), and uses its functions. (also uses log4cplus's .h files , naturally). When I try to compile my project as a static library, it succeeeds. When I try as DLL, it fails : 1>MessageWriter.obj : error LNK2019: unresolved external symbol "public: static class log4cplus::Logger __cdecl log4cplus::Logger::getInstance(class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> > const &)" (?getInstance@Logger@log4cplus@@SA?AV12@ABV?$basic_string@_WU?$char_traits@_W@std@@V?$allocator@_W@2@@std@@@Z) referenced in function "class log4cplus::Logger __cdecl Log(void)" (?Log@@YA?AVLogger@log4cplus@@XZ) There are 4 more errors just like this related to functions within log4cplus.lib. It seems like something really stupid.. please help me :) Thanks!

• Problem running ASP.NET MVC 2 website on IIS7

  - by Charlie

  I'm trying to deploy my ASP.NET MVC 2 website from VS2010 beta 2 to IIS7. The publish works fine but none of the routes work, so when I go to the URL http://localhost/myapp/Home/Index I get the error: HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. I'm deploying to a virtual directory which is using an app pool configured for the .NET 4 framework with managed pipeline mode set to integrated. Also, if I go Basic Settings-Test Connection, both tests pass. From what I understand, it should just work? I don't have any problems deploying Nerd Dinner from VS2008, that works fine.

• Is there a good AddIn for Visual Studio that will launch msbuild targets?

  - by Jon Lent

  One of the things I like about the Java IDEs out there is that they typically have the ability to allow a user to right-click on an Ant file and run one of the targets. I've got an msbuild file in my solution that is used for migrating the application database, and would kill to be able to right-click on it, select "update" or "rollback" and have it run. My searching has not turned up anything meant to run inside VS2008, just a shell extension for windows explorer. Has anybody seen such an animal out there? Cordially, Jon

• Boot strapper for VSTO 3.0 SP1

  - by Amjid Qureshi

  Hi, I've got a .net 3.5 vs2008 Excel addin. I've created an installer for it and have it working apart from the fact that I cant get an option in the prerequisites for VSTO 3.0 SP1. I have one for VSTO 3.0 and when I check the C:\Program Files (x86)\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\VSTOR30 directory it has vstor30.exe vstor30sp1-KB949258-x86.exe product.xml "en" directory. However when I build the installer only the vstor.exe file gets copied over to the bin directory. I need vstor3.0sp1 for the addin to work. If I manually install vstor sp1 then everything works fine.

• Custom format document option in visual studio. Formatting CSS tags.

  - by Batu

  Hi, When i work in VS2008, i use the Ctrl+K+D very often as it saves a lot of time. But in CSS files, this command formats the document in a way i don't quite like. For example when i auto format the document, .Foo { width:1px; height:2px; } However, i like to format tags this way, as it is much more easy to read (in my opinion): .Foo { width:1px; height:2px; } So, are there any way that i can implement this ? The "Tag specific options" feature seems to be the thing that i need, but i am not quite sure how to do this. Thanks.

• WinForms: Why do I get InvalidCastException when showing folder browser dialog?

  - by Marek

  I am randomly getting InvalidCastException when showing FolderBrowserDialog and also many clients have reported this. I have not been able to find anything relevant on the internet. Does anyone know what causes this/how to fix this? My code: using (FolderBrowserDialog fbd = new FolderBrowserDialog()) { fbd.ShowNewFolderButton = false; if (fbd.ShowDialog() == DialogResult.OK) Stack trace: Error: System.InvalidCastException: 'Unable to cast object of type 'System.__ComObject' to type 'IMalloc'.'. Stack trace: at System.Windows.Forms.UnsafeNativeMethods.Shell32.SHGetMalloc(IMalloc[] ppMalloc) at System.Windows.Forms.FolderBrowserDialog.GetSHMalloc() at System.Windows.Forms.FolderBrowserDialog.RunDialog(IntPtr hWndOwner) at System.Windows.Forms.CommonDialog.ShowDialog(IWin32Window owner) at System.Windows.Forms.CommonDialog.ShowDialog() EDIT: Additional information: I have been able to reproduce this only when running in VS2008 debugger. When running out of debugger, it happens only very rarely (happened once or twice in 6 months) on my 64 bit Windows 7 and goes away after restart. The clients are certainly not running the app in debugger so it is surely reproducible out of debugger.

• Visual Studio confused by server code inside javascript

  - by Felix

  I ran into an annoying problem: the following code gives a warning in Visual Studio. <script type="text/javascript"> var x = <%: ViewData["param"] %>; </script> The warning is "Expected expression". Visual Studion gets confused, and all the javascript code after that is giving tons of warnings. Granted, it's all warnings, and it works perfectly fine in runtime - but it is very easy to miss real warnings among dozen of false positives. It was working the same way in VS2008, and it wasn't fixed in VS2010. Does anybody know if there is a workaround, or a patch?

• Windows Mobile Development on MacBook Pro?

  - by Ted Nichols

  I am a frequent Windows Mobile application developer in need of a new development laptop. I am considering a MacBook or Macbook Pro running either Fusion from VMWare or Parallels Desktop. This will give me the option to port my applications to the iPhone depending on what MS does with WM 6.5 and 7. Has anybody tried doing Windows Mobile development using Microsoft Windows Mobile Device Center (or ActiveSync) and VS2008 on the MacBook Pro using one of these virtual machines? Does the device emulator work properly? What about debugging a Windows Mobile device over a USB cable? In general, do most USB drivers (non HID) designed for Windows work under these virtual machines? Thanks.

• Clipping the caret in a C# program

  - by Bob Sammers

  I'm creating a WinForms control in C# (using VS2008, .net 3.5) which allows text input. I've imported the necessary Win32 API functions from User32.dll for displaying the normal Windows caret and these are all working fine, but it's not displaying exactly how I'd like it. Text is displayed on the control with a blank border and I use Graphics.SetClip() to leave this margin clear. I want the caret to be clipped to the same region, but since I don't paint it and there's no obvious API function to set a clipping region, I can't see any way of doing this. Have I missed anything obvious? The caret is clipped inside the control in which it is drawn. I'm therefore aware that one solution could be to place the text in a separate sub-control with no border. However, if there's a simpler way than redesigning this part of the control, I'd like to look for that first. Thanks in advance for any help!

• Mercurial Messing Up csproj Files?

  - by alphadogg

  I am using Hg to manage and merge code with three other developers involved in a VS2008 project. We do have an .hgignore file that ignores a fair number of files not necessary to track, such as *.pdb, *.obj, etc. However, we do track .csproj files. Periodically, it would seem that files go missing after a merge. We would get build issues, and have to relocate files which were in the project folders, but not in the csproj file. Eventually, I noted during a merge conflict that sometimes Hg seems to merge incorrectly. Here's a screenshot below. The actual conflict that requires manual intervention is lower in the file. But in this section, hg incorrectly replaces DirectoryTasks.cs with a new, different file called ReportTasks.cs, when in fact, both should be added. How do people manage to avoid this?

• ExpectedException on TestMethod Visual Studio 2010

  - by Joop

  Today I upgraded my solution with all the underlying projects from VS2008 to VS2010. Everything went well except for my unit tests. First of all only the web projects had as target framework .NET 4. All the other projects still had .NET 3.5. I changed them all to .NET 4. Now when I debug my unit tests it breaks on every exception. In 2008 it just wouldn't pass and tell me that an exception occurred. Even when I have the ExpectedException attribute defined it stops debugging on every exception. And example of one of my tests: [TestMethod] [ExpectedException(typeof(EntityDoesNotExistException))] public void ConstructorTest() { AddressType type = new AddressType(int.MaxValue); } The EntityDoesNotExistException is a custom exception and inherits Exception.

• project organization between x86 and x64

  - by Steve

  I have a mixed language solution in VS2008. I would like to structure the bin such that I have bin\x86\Release and bin\x64\Release among the other options. I can do something like this if I have all C# or all C++, but as the platform names don't overlap (x86 vs. Win32) between C++ and C#, I can't seem to do this with the macros (and have an easy solution). I've tried to add a new platform and it won't let me. Is there an easy way to do this?

• Using Application Settings and reading defaults from app.config

  - by Peter Goras

  Hi, I need to deploy a Windows Forms application using ClickOnce deployment. (VS2008, .NET 3.5) And I need to provide a configuration file for this app that any user can modify. For this reason, I am using Application Settings instead of standard appSetttings in app.config so I can separate the the user config from app config. see http://msdn.microsoft.com/en-us/library/ms228995(VS.80).aspx Creating a Settings.settings file using VS generated a class with hard-coded default values like this: [global::System.Configuration.DefaultSettingValueAttribute("blahblah")] public string MyProperty ... WTF? I want to read the default values from the app.config! So I created my own class deriving from ApplicationSettingsBase but I cannot get this to read values from the app.config. Any ideas?

• COM on Windows7 and Visual Studio

  - by vikasde

  I registered a COM dll (under administrator) using regsvr32, which I want to use in Visual Studio 2008 (under administrator) for my project in Windows 7. Now, when I try to use the interfaces and classes from the COM, then I can't see any of the methods. When I use the object browser to view the COM classes, then I can see that they are all empty. However when I use the same COM on windows XP using VS2008, then all methods are suddenly available. Does anybody know why this is happening and how to get this working under Windows 7?
