• C# class in a directory without having the directory name in its namespace

  - by PaN1C_Showt1Me

  Hi ! If you add a directory in your Visual Studio project and you add a class inside it, the namespace will respect the whole path the directory inclusive. But sometimes, I prefer having the class in the main project namespace, although it lies in a directory structure, just because I don't want to have mess in my code. So often happens that I rewrite the Myproject.MyDirectory namespace to be Myproject only. Is it OK in your opinion? Or does any convention say that every class inside the directory must have it included in the namespace ? Thanks

• How to run an .exe application in another computer?

  - by ADAM

  I am working on a C# application in Visual Studio 2013. When I run the .exe file from my computer, the application runs very well and all the features work. When I tried to run the .exe on another computer, the database side doesn't work well and the connection with the database couldn't be opened. The SqlConnection is constructed as follows: SqlConnection cn = new SqlConnection("Data Source=ADAM-PC;Initial Catalog=integrationdatabase;Integrated Security=True" I don't know how to change the data source to make the connection with the database established in another computer. How can I solve this problem?

• Dynamic WSDL Location in .NET

  - by wadetandy

  I am building a C# application that is consuming a WSDL that is hosted by a server on our network. When I use the "Add Web Reference" functionality of Visual Studio, it works just fine, saving the ip address of the machine, etc. and the SOAP calls work without any issue. We are now making this entire application portable so that it can be installed in any environment. We would like to place all of our settings in one configuration file, so my question is this: Is it possible to somehow specify the IP address of the machine that is hosting the SOAP service in my configuration file and link everything dynamically at runtime?

• Is there a convention for organizing the include/exports in a large C++ project ?

  - by BlueTrin

  Hello, In a large C++ solution, is there a best/standard way to separate the include files necessary to build an intermediary DLL and the include files which will be used by the DLL clients ? We have grouped all the include files in a folder called Interface (for DLL interface), but there the customers have to either include the Interface folder as a default include folder or type the full name as: #include "ProjectName/Interface/myinterface.h" Wouldn't it be better to create a separate folder called exports where I would create a folder called ProjectName and put the include files there ? So that the customers would be typing: #include "ProjectName/myinterface.h" If I do the thing right above, then should I keep the files within the solution and produce a post build event (I use Visual Studio 2k5) to copy the files into the "export" folder (/ProjectName/) ? Or is it better to just include directly the files from this folder within my project (this is more direct and has less chances to cause maintenance issues ? I am more looking for advice than for a definite solution. Thank you for reading this ! Anthony

• VS 2008 linking error

  - by AvatarBlue

  I'm using Visual Studio 2008 C++ and working on a dll project. Debug compiled and linked perfectly but when I compile the release version, it shows this: VImgPtr.obj : error LNK2001: unresolved external symbol @__security_check_cookie@4 VLibraryPtr.obj : error LNK2001: unresolved external symbol "void __cdecl operator delete[](void *)" (??_V@YAXPAX@Z) D:\Source Code\VImgLib\Release-vc9u\VImgLib-vc9u.dll : fatal error LNK1120: 2 unresolved externals If I selected Multi-threaded (/MT) in "C/C++-Code Generation tab), it linked ok. The problem is only when I choose Multi-threaded DLL (/MD). I'm releasing a dll, so should be /MD right?

• What are the advantages / disadvantages of a Cloud-based / Web-based IDE?

  - by Gabe

  I'm writing this as DevConnections in Las Vegas is happening. Visual Studio 2010 has been released and I now have this 3GB beast installed to my machine. (I'll admit, it has some nice features.) However, while the install was monopolizing my computer's resources I began to wish that my IDE worked more like Google Documents (instantly available, available anywhere, easy to share, easy to collaborate, naturally versioned). A few Google (and StackOverflow) searches led me to : Coderun Bespin I'm well aware that these IDE's are missing a lot of what exists in VS 2010. However, that isn't my question. Instead, I'm wondering what benefits a web-based IDE might have? Assuming a company invests the time to create the missing features, what is the downside?

• How to Import Excel Data into Silverlight App for Visualization?

  - by Ulf

  Hi there, Im building an Silverlight Application (Silverlight 4, Visual Studio 2010), in which the user can generate Charts (line-Charts, Bar Chart) dynamically, by entering a specific time period. At the Moment i have no idea how to import the data to Silverlight, to generate the Charts. My data is stored in 4 Excel Tables and i have no clue what would be the best way to get that data into Silverlight? I read a lot of examples using SQL Server as Database, but unfortunatly SQL Server is no choice for me. Any help would be great!

• strange results with /fp:fast

  - by martinus

  We have some code that looks like this: inline int calc_something(double x) { if (x > 0.0) { // do something return 1; } else { // do something else return 0; } } Unfortunately, when using the flag /fp:fast, we get calc_something(0)==1 so we are clearly taking the wrong code path. This only happens when we use the method at multiple points in our code with different parameters, so I think there is some fishy optimization going on here from the compiler (Microsoft Visual Studio 2008, SP1). Also, the above problem goes away when we change the interface to inline int calc_something(const double& x) { But I have no idea why this fixes the strange behaviour. Can anyone explane this behaviour? If I cannot understand what's going on we will have to remove the /fp:fastswitch, but this would make our application quite a bit slower.

• Using same Debug settings for Start External Program across 32 bit and 64 bit debug environments

  - by Michael Prewecki

  We use a mixture of 32-bit and 64-bit development environments. Some of our class libraries are debugged using a 32-bit application so we have debug settings for "Start External Program" and "Working Directory". The problem is that the settings need to be different since the 32-bit application is installed to C:\Program Files\xxx (on the 32-bit dev enviroment) or C:\Program Files (x86)\xxx (on the 64-bit dev environment) Is there a way to use some sort of tag like %PROGRAMFILES% or $(ProgramFiles) so that Visual Studio 2008 will know where to look for the external program? This wouldn't be a major issue except the solution file (where the debug information is saved) is checked into source control...so getting the latest version of the solution from our source repository keeps yoyo'ing the debug settings between the two program files locations.

• Not finding the metadata window (F12) when using Resharper

  - by Arjan Einbu

  When I hit F12 (or right-click and select Go To Definition) in Visual Studio on code I don't have the source for, it should bring up a generated metadata file. (Very similar to the Code Definition Window) This doesn't work when ReSharper (R#) is installed. After R# is installed, the Object Browser opens instead. I've had this problem on several fresh installed computers, and at least since R# 3. (You'll see this works again when you disable R# and restart VS) How can I get to the metadataview now?

• CUDA & VS2010 problem

  - by Kristian D'Amato

  I have scoured the internets looking for an answer to this one, but couldn't find any. I've installed the CUDA 3.2 SDK (and, just now, CUDA 4.0 RC) and everything seems to work fine after long hours of fooling around with include directories, NSight, and all the rest. Well, except this one thing: it keeps highlighting the <<< >>> operator as a mistake. Only on VS2010--not on VS2008. On VS2010 I also get several warnings of the following sort: C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include\xdebug(109): warning C4251: 'std::_String_val<_Ty,_Alloc>::_Alval' : class 'std::_DebugHeapAllocator<_Ty>' needs to have dll-interface to be used by clients of class 'std::_String_val<_Ty,_Alloc>' Anyone know how this can be fixed?

• How should open source libraries be used on Windows?

  - by Jason Owen

  There are many open-source libraries that can be compiled with Visual Studio. I'm porting a program from Linux to Windows, but it depends on a number of libraries. I don't know what the best practices regarding libraries are on Windows. On Linux, these libraries are typically part of the distribution. To use sqlite on Debian, for example, you need only to install libsqlite3-dev and the include files and libraries (both static and dynamic) are automatically installed and available to your program. If you need a different version than your distribution supplies, you can compile it in your home directory, install it to ~/include and ~/lib, and set the appropriate environment variables so that your compiler includes those directories in its search path. What is the best way to use libraries that are distributed as source on Windows? If I link dynamically rather than statically, is there an easy way to copy required DLLs into the output directory to ease redistribution (assuming license requirements are met)?

• Does XAML design mode support more color than code view?

  - by Rahul Soni

  While working with SilverLight using Visual Studio 10, I found that in design mode XAML allows a wide plethora of colors. For ex. Lime is a valid color in XAML. <LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5"> <GradientStop Color="Yellow" Offset="0" /> <GradientStop Color="Lime" Offset="1" /> While working with code though, I found that Lime and many other colors are missing... GradientStop blueGS = new GradientStop(); blueGS.Color = Colors.Lime; What am I missing? Both of these colors belong to System.Windows.Media.Colors.

• msbuild conversion tool to VS2010

  - by prosseek

  I got vcproj file from QMake (qmake -tp vc win32.pro), and when I run it with msbuild (msbuild for VS 2010), I get the following error. MSBUILD : error MSB4192: The project file ".\win32.vcproj" is in the ".vcproj" or ".dsp" file format , which MSBuild cannot build directly. Please convert the project by opening it in the Visual Studio IDE or running the conversion tool, or, for ".vcproj", use MSBuild to build the solution file conta ining the project instead. I'd like to run the conversion tool for getting VS2010 project file. What's the tool for it?

• How to change the default Help browser for VS2010?

  - by Scott Bilas

  Visual Studio 2010 changed the help system to run a little daemon and launch the system default web browser to view it. I'm using Firefox for my system browser but would like to use Chrome for VS help. Is there an option to change the Help browser that I'm not seeing in Tools|Options? If not, is there a workaround or registry setting to do this? As a backup I've been using H3Viewer but I'd like to be able to get context-sensitive F1 help from within the VS IDE.

• Is it possible to manipulate the format on a DataGridView that is bound to a Data Source?

  - by Jack Johnstone

  I´m using SQL Server 2005 and Visual Studio 2008, C#. In the data source (the SQL Server data table) I use the date format mm/dd/yyyy, however, in a forms overview (DataGridView) users would like to see a completely other format, with year, week number and day number of week (yyww,d). I´ve created an algorithm for this transformation, but can I populate the affected cells with yyww,d instead of mm/dd/yyyy? And in that case - how would I do it? I guess I need to do it after the cells are populated, but before they are shown. The generic question is - how do I manipulate the format of Data Source bound DataGridView cells.

• C# - Copy dlls to the exe output directory when using dependency injection with no references?

  - by NotDan

  I have a C# solution that I am using dependency injection to resolve references between dlls. I have an exe project and some other dll projects that are not referenced by the exe (It uses the dlls through the IoC container). The project settings are the default, visual studio settings where it builds each dll in it's own folder. Since the exe doesn't reference the dlls, they never get copied to the output directory of the exe and don't get found by the IoC framework. How do you handle this? Do you build them all in the same directory? Use post build copy commands? Or something else?

• Accented character replacement for search then reinserted afterwards

  - by user314573

  Basically my issue is that users would like to search for a french word that has accented characters but without typing in the accented characters and then have the actual accented word appeared highlighted if found... So for example they would type in "declare" but in the result sets it would look like "déclare" and if found "déclare" would be highlighted. My first thought was to just simply replace the characters with a regex but then I remembered that I would need to re-insert the replaced characters after the search... I was thinking of then using some sort of character map that would track position and the character so that when the search was finshed I could put the result set back to the way it was. This seems a little brute force to me and I was wondering if anyone had a better alternative? I'm using Visual Studio 2005 with this app. Any advice would be much appreciated! Thanks

• Is there a method / system / program to keep track of different stages and changes in writing the co

  - by Luay

  forgive me, but I don't know the technical term to know what to search for. I am trying to find a way to keep track of changes in my code during the development of my program. something that would allow me to go back to a section of code that I deleted. I am not talking about "undo". But rather a way that would let me keep track or be able to retrieve a section of my code that I deleted but now want it back. Is there such a way. If there is, then what is this whole system/procedure called? Is there something that integrates with visual studio 2010? Many thanks for your help.

• To be a lazy developer or not to be a lazy developer?

  - by JamesStuddart

  Am I a lazy developer? Is it being lazy to use automated tools, such as code generators and such? Now, I could, if I had to, create all the data layers and entities I needed, but I choose to use CodeSmith to generate my datalayers and entities. I also use Resharper and I would say it fights with MSDeploy as to which gets installed first after Visual Studio. Again if I had to, I could code without it, but prefer not to. Both these tools from my point of view are no brainers as they improve output massively. But is this lazy? I'm sure there are purists out there that would say everything should be wirtten by you so you know what everything is doing, but if you can read through the code and see what is happening is that ok? So am I being lazy or am I just using all the cards in my hand?

• Debugging ASP.NET with IIS

  - by Ariel

  I've set up debugging in Visual Studio 2008 to IIS instead of the built in server so I can run url rewriting while developing (using IIRF). It took a while to get to work (changing permissions, reinstalling the .NET framework) but it was working. I turned off my machine, and now that it's back on the debugger won't start. I'm using Parallels with WinXP on an iMac. "Unable to start debugging on the web server. Could not start ASP.NET debugging. More information may be available by starting the project without debugging" I read a whole bunch of posts on SO as well as googled the subject but none seem to provide a working answer. Has anyone encountered this and knows how to get it to work? Thanks.

• .NET 4.0 Debugging Behavior

  - by Jason

  We recently migrated to VS 2010. We installed .NET 4.0 on our test machine. When we execute a console application that throws an exception, we no longer see the exception message and stack trace printed to the console but instead see the message An unhandled win32 exception occurred in something.exe [PID]. Just-In-Time debugging this exception failed with the following error: No installed debugger has Just-In-Time debugging enabled. In Visual Studio, Just-In-Time debugging can be enabled from Tools/Options/Debugging/Just-In-Time. We do have the above setting enabled. What do we need to do to return to the behavior we had previously?

• How do I use functions from a DLL?

  - by Russel

  How do I use functions from a DLL? I'm a total newbie and I don't really understand how to use functions from a DLL file. I'm trying to use MS Visual Studio 2008 (C++). My understanding is that the DLL files will have corresponding header files and as long as I include the header files and call the functions normally in my code, it should work? Is that correct? Then I would just need to have the compiled exe file be able to find the DLL? Please let me know if that is a remotely correct understanding! Thanks! Russel
