  • How can I change the font color of the VS2012 Source Control Explorer window?

    - by RM.
    I am using Visual Stuido 2012 Integrated Shell with Team Explorer. I would like to change the default font color of the mapped and not mapped folders in the Source Control Explorer (in the treeview). I tried the Visual Studio Color Theme editor, but it seems like the font color of the Source Control Explorer and the Team Explorer can not be changed by it. I also looked at Tools|Options|Environment|Fonts and Color for a setting but did not find anything. Is it possible to change the font color? How?

  • What happened to Debug test in current context (Ctrl+R, Ctrl+T) in VS2012?

    - by Nilzor
    One of the hot-keys I used most in Visual Studio 2010 was Ctrl+R, Ctrl+T, which ran the unit test the cursor currently was on in debug mode. I think the command is named "Debug tests in current context". Now, you still have a command named Test.DebugTestsInCurrentcontext, but when I assign it to a key combination and activate it, it always yields "currently not available". I do know that there is a new function in the Test menu named "Debug selected test" - but I think that mappes to the selected tests in the Test Explorer, not the file editor. What gives, Microsoft? Are you removing features?

  • Task failed because "sgen.exe" was not found

    - by Kinze
    I am getting the following error when attempting to build my project in Visual Studio 2008 Professional Edition: *Task failed because “sgen.exe” was not found, or the correct Microsoft Windows SDK is not installed. The task is looking for “sgen.exe” in the “bin” subdirectory beneath the location specified in the InstallationFolder value of the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\Windows\v6.0A. You may be able to solve the problem by doing one of the following: 1) Install the Microsoft Windows SDK for Windows Server 2008 and .NET Framework 3.5. 2) Install Visual Studio 2008. 3) Manually set the above registry key to the correct location. 4) Pass the correct location into the “ToolPath” parameter of the task.* I tried downloading Microsoft Windows SDK for Windows Server 2008 and .NET Framework 3.5, and still get the error. I also tried downloading the Windows 7 SDK and .NET Framework 3.5 and still same result. I also tried to manually editing the registry to change the InstallationFolder and I tried repairing the Visual Studio install. The project was originally created on WinXP and I am trying to compile on a reformatted machine running Windows 7 Enterprise.

  • Request for the permission of type 'System.Web.AspNetHostingPermission' failed when compiling web si

    - by ahsteele
    I have been using Windows 7 for a while but have not had to work with a particular legacy intranet application since my upgrade. Unfortunately, this application is setup as an ASP.NET Website project hosted on a remote server. When I have the website open in Visual Studio 2008 and try to debug it I get the following compiler error: Request for the permission of type 'System.Web.AspNetHostingPermission' failed To resolve this issue on Windows Vista machines, I would change the machine's .NET Security Configuration trust level to full for the local intranet (fix outlined here).

  • Looking for Antlr Grammar syntaxt highlight in VS2010

    - by David Mårtensson
    I am looking for some way to edit antlr grammar files directly within VS2010 with syntax highlight. I have used antlrworks a lot but it has the drawback that I have to start antlrworks separately and then browse to the file I want to edit, do the changed and save. For minor fixes I do not need all the tools in Antlrworks but I still would like the syntax highlight. But I have not been able to get VS2010 to open antlrworks with the right file and I have found no other way to get syntax highlight directly within VS2010 editor, it just opens as plain text. I can get visual studio to open antlrworks but it will open with only the last set of files it had open, not the one I clicked on. So my question(s) are: Is there a way to get antlrworks to open with the right file when I double click in it in visual studio project explorer? Is there any other way to get correct syntax highlight for antlr grammar files within visual studio (or with another editor, preferably not one that costs money, but if there are no free ones a commercial one might be an option).

  • VS2010 compiles solution without errors, msbuild fails: "fatal error CS0002: Unable to load message string from resources"

    - by Nathan Ridley
    I'm having a lot of trouble trying to track down the cause of this error message. I have a large Visual Studio 2010 solution which compiles without error on my local machine but on the build server, msbuild fails on one of the projects with the error: fatal error CS0002: Unable to load message string from resources Here's the red error section at the end: Build FAILED. "C:\TeamCity\buildAgent\work\85eff164854b9e67\Libraries\Domainface.Proxy.Common\Domainface.Proxy.Common.csproj" (default target) (9) -> (CoreCompile target) -> CSC : fatal error CS0002: Unable to load message string from resources. [C:\TeamCity\buildAgent\work\85eff164854b9e67\Libraries\Domainface.Proxy.Common\Domainface.Proxy.Common.csproj] 0 Warning(s) 1 Error(s) The entire msbuild output from the build server is here: http://pastie.org/3660842 What does the error generally refer to, that would cause it to build locally but not on the build server? UPDATE I have just run msbuild /version on both machines and it turns out the .net framework versions are very slightly different. Local machine is 4.0.30319.488 and build server is 4.0.30319.1. I'm about to run windows update on the server to allow it to install some updates, as several seem to be .net framework-related, so I'll see if that makes a difference. UPDATE Installing the updates didn't help. Just remembered I copied up csc.exe from the async preview a little while ago in order to facilitate async compilation (the actual async preview had failed to install on the server due to visual studio not being there, but installing visual studio team viewer seems to have fixed that, so i've just run the proper async ctp3 installer to see if that makes a difference.

  • Building a News-feed that comprises posts "created by user's connections" && "on the topics user is following"

    - by aklin81
    I am working on a project of Questions & Answers website that allows a user to follow questions on certain topics from his network. A user's news-feed wall comprises of only those questions that have been posted by his connections and tagged on the topics that he is following(his expertise topics). I am confused what database's datamodel would be most fitting for such an application. The project needs to consider the future provisions for scalability and high performance issues. I have been looking at Cassandra and MySQL solutions as of now. After my study of Cassandra I realized that Simple news-feed design that shows all the posts from network would be easy to design using Cassandra by executing fast writes to all followers of a user about the post from user. But for my kind of application where there is an additional filter of 'followed topics', (ie, the user receives posts "created by his network" && "on topics user is following"), I could not convince myself with a good schema design in Cassandra. I hope if I missed something because of my short understanding of cassandra, perhaps, can you please help me out with your suggestions of how this news-feed could be implemented in Cassandra ? Looking for a great project with Cassandra ! Edit: There are going to be maximum 5 tags allowed for tagging the question (ie, max 5 topics can be tagged on a question).

  • Two objects with dependencies for each other. Is that bad?

    - by Kasper Grubbe
    Hi SO. I am learning a lot about design patterns these days. And I want to ask you about a design question that I can't find an answer to. Currently I am building a little Chat-server using sockets, with multiple Clients. Currently I have three classes. Person-class which holds information like nick, age and a Room-object. Room-class which holds information like room-name, topic and a list of Persons currently in that room. Hotel-class which have a list of Persons and a list of Rooms on the server. I have made a diagram to illustrate it (Sorry for the big size!): http://i.imgur.com/Kpq6V.png I have a list of players on the server in the Hotel-class because it would be nice to keep track of how many there are online right now (Without having to iterate through all of the rooms). The persons live in the Hotel-class because I would like to be able to search for a specific Person without searching the rooms. Is this bad design? Is there another way of achieve it? Thanks.

  • Game architecture: modeling different steps/types of UI

    - by Sander
    I have not done any large game development projects, only messed around with little toy projects. However, I never found an intuitive answer to a specific design question. Namely, how are different types/states of UI modeled in games? E.g. how is a menu represented? How is it different from a "game world" state (let's use an FPS as an example). How is an overlaid menu on top of a "game world" modeled? Let's imagine the main loop of a game. Where do the game states come into play? It it a simple case-by-case approach? if (menu.IsEnabled) menu.Process(elapsedTime); if (world.IsEnabled) world.Process(elapsedTime); if (menu.IsVisible) menu.Draw(); if (world.IsVisible) world.Draw(); Or are menu and world represented somewhere in a different logic layer and not represented at this level? (E.g. a menu is just another high-level entity like e.g. player input or enemy manager, equal to all others) foreach (var entity in game.HighLevelEntities) entity.Process(elapsedTime); foreach (var entity in game.HighLevelEntities) entity.Draw(elapsedTime); Are there well-known design patterns for this? Come to think of it, I don't know any game-specific design patterns - I assume there are others, as well? Please tell me about them.

  • LinqToSQL not updating database

    - by codegarten
    Hi. I created a database and dbml in visual studio 2010 using its wizards. Everything was working fine until i checked the tables data (also in visual studio server explorer) and none of my updates were there. using (var context = new CenasDataContext()) { context.Log = Console.Out; context.Cenas.InsertOnSubmit(new Cena() { id = 1}); context.SubmitChanges(); } This is the code i am using to update my database. At this point my database has one table with one field (PK) named ID. *INSERT INTO [dbo].Cenas VALUES (@p0) -- @p0: Input Int (Size = -1; Prec = 0; Scale = 0) [1] -- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 4.0.30319.1* This is LOG from the execution (printed the context log into the console). The problem i'm having is that these updates are not persistent in the database. I mean that when i query my database (visual studio server explorer - new query) i see the table is empty, every time. I am using a SQL Server database file (.mdf).

  • Where can a self-teacher learn general good programming habits and conventions?

    - by lucid
    A few mistakes and general childishness in early adulthood have left me in a situation where I work a menial job, with no possibility (in the near future) of attending school. I aspire to one day work in the programming field (gaming specifically), after proving myself on the indie end of things. I've gotten very confident in C++, java, and python, and I find I'm able to solve any problem I want either from previous experience, or from scouring the web for help. The solutions work, and with each attempt they become more readable, maintainable, and extensible. But this is because I'm learning from mistakes and bad programming and design habits I feel I might have avoided with actual schooling. General tips like: "if it's hard to read or getting long, or you're writing it twice, it should be in one or more functions." or "design all your classes before you start coding, so you don't have to rewrite classes later when you discover an unforeseen dependency" Is there a good book or website for learning general good programming practices and design habits? Also, naming and format conventions. I realize sometimes development houses have their own conventions, but things like "Classes in python usually have the first letter of each word capitalized". I'd like to be able to show some source code to a potential employer, and be prepared when for what's expected on a team. Is there some central database of naming and formatting conventions somewhere? Also, feel free to give any thoughts on whether or not the self-teach, garner some indie sales, use them as your resume' route is realistic

  • C++ Matrix class hierachy

    - by bpw1621
    Should a matrix software library have a root class (e.g., MatrixBase) from which more specialized (or more constrained) matrix classes (e.g., SparseMatrix, UpperTriangluarMatrix, etc.) derive? If so, should the derived classes be derived publicly/protectively/privately? If not, should they be composed with a implementation class encapsulating common functionality and be otherwise unrelated? Something else? I was having a conversation about this with a software developer colleague (I am not per se) who mentioned that it is a common programming design mistake to derive a more restricted class from a more general one (e.g., he used the example of how it was not a good idea to derive a Circle class from an Ellipse class as similar to the matrix design issue) even when it is true that a SparseMatrix "IS A" MatrixBase. The interface presented by both the base and derived classes should be the same for basic operations; for specialized operations, a derived class would have additional functionality that might not be possible to implement for an arbitrary MatrixBase object. For example, we can compute the cholesky decomposition only for a PositiveDefiniteMatrix class object; however, multiplication by a scalar should work the same way for both the base and derived classes. Also, even if the underlying data storage implementation differs the operator()(int,int) should work as expected for any type of matrix class. I have started looking at a few open-source matrix libraries and it appears like this is kind of a mixed bag (or maybe I'm looking at a mixed bag of libraries). I am planning on helping out with a refactoring of a math library where this has been a point of contention and I'd like to have opinions (that is unless there really is an objective right answer to this question) as to what design philosophy would be best and what are the pros and cons to any reasonable approach.

  • What's the best way to store Logon User information for Web Application?

    - by Morgan Cheng
    I was once in a project of web application developed on ASP.NET. For each logon user, there is an object (let's call it UserSessionObject here) created and stored in RAM. For each HTTP request of given user, matching UserSessoinObject instance is used to visit user state information and connection to database. So, this UserSessionObject is pretty important. This design brings several problems found later: 1) Since this UserSessionObject is cached in ASP.NET memory space, we have to config load balancer to be sticky connection. That is, HTTP request in single session would always be sent to one web server behind. This limit scalability and maintainability. 2) This UserSessionObject is accessed in every HTTP request. To keep the consistency, there is a exclusive lock for the UserSessionObject. Only one HTTP request can be processed at any given time because it must to obtain the lock first. The performance and response time is affected. Now, I'm wondering whether there is better design to handle such logon user case. It seems Sharing-Nothing-Architecture helps. That means long user info is retrieved from database each time. I'm afraid that would hurt performance. Is there any design pattern for long user web app? Thanks.

  • How to understand existing projects

    - by John
    Hi. I am a trainee developer and have been writing .NET applications for about a year now. Most of the work I have done has involved building new applications (mainly web apps) from scratch and I have been given more or less full control over the software design. This has been a great experience however, as a trainee developer my confidence about whether the approaches I have taken are the best is minimal. Ideally I would love to collaborate with more experienced developers (I find this the best was I learn) however in the company I work for developers tend to work in isolation (a great shame for me). Recently I decided that a good way to learn more about how experienced developers approach their design might be to explore some open source projects. I found myself a little overwhelmed by the projects I looked at. With my level of experience it was hard to understand the body of code I faced. My question is slight fuzzy one. How do developers approach the task of understanding a new medium to large scale project. I found myself pouring over lots of code and struggling to see the wood for the trees. At any one time I felt that I could understand a small portion of the system but not see how its all fits together. Do others get this same feeling? If so what approaches do you take to understanding the project? Do you have any other advice about how to learn design best practices? Any advice will be very much appreciated. Thank you.

  • UpdateModelFromDatabaseException when trying to add a table to Entity Framework model

    - by Agent_9191
    I'm running into a weird issue with Entity Framework in .NET 3.5 SP1 within Visual Studio 2008. I created a database with a few tables in SQL Server and then created the associated .edmx Entity Framework model and had no issues. I then created a new table in the database that has a foreign key to an existing table and needed to be added to the .edmx. So I opened the .edmx in Visual Studio and in the models right-clicked and chose "Update Model From Database...". I saw the new table in the "add" tab, so I checked it and clicked finish. However I get an error message with the following text: --------------------------- Microsoft Visual Studio --------------------------- An exception of type 'Microsoft.Data.Entity.Design.Model.Commands.UpdateModelFromDatabaseException' occurred while attempting to update from the database. The exception message is: 'Cannot update from the database. Cannot resolve the Name Target for ScalarProperty 'ID <==> CustomerID'.'. --------------------------- OK --------------------------- For reference, here's the tables seem to be the most pertinent to the error. CustomerPreferences already exists in the .edmx. Diets is the table that was added afterwards and trying to add to the .edmx. CREATE TABLE [dbo].[CustomerPreferences]( [ID] [uniqueidentifier] NOT NULL, [LastUpdatedTime] [datetime] NOT NULL, [LastUpdatedBy] [uniqueidentifier] NOT NULL, PRIMARY KEY CLUSTERED ( [ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] CREATE TABLE [dbo].[Diets]( [ID] [uniqueidentifier] NOT NULL, [CustomerID] [uniqueidentifier] NOT NULL, [Description] [nvarchar](50) NOT NULL, [LastUpdatedTime] [datetime] NOT NULL, [LastUpdatedBy] [uniqueidentifier] NOT NULL, PRIMARY KEY CLUSTERED ( [ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO ALTER TABLE [dbo].[Diets] WITH CHECK ADD CONSTRAINT [FK_Diets_CustomerPreferences] FOREIGN KEY([CustomerID]) REFERENCES [dbo].[CustomerPreferences] ([ID]) GO ALTER TABLE [dbo].[Diets] CHECK CONSTRAINT [FK_Diets_CustomerPreferences] GO This seems like a fairly common use case, so I'm not sure where I'm going wrong.

  • Why do my debugger randomly jump out of debug mode?

    - by Clean
    Hi, I'm experiencing a very annoying behavior with the debugger in Visual Studio 2008 Professional. I'm debugging a ASP.NET web application, and when stepping through the code the debugger randomly "jumps out" of debug mode, but without the debugger stopping. So when I'm stepping through my code like this: step over, step over, step over, step over, ... , step over The debugger continues as If I was pressing Continue, like this: step over, step over, step over, step over, ... , continue Thing is, I never touch continue! So, the debugger is still running, the ASP.NET page renders, but my "stepping" ends. This is of course very annoying. And it happens totally randomly. Before switching to Windows 7 and IIS 7.5, I've never experienced this problem. My colleague who debugs the exact same code, but on a Windows XP machine running IIS 6 have never had this problem either. So my thought is, perhaps this is Windows 7 or IIS 7.5 related? I've already made sure <compilation defaultLanguage="c#" debug="true" /> is set in web.config. Have anyone experienced the same problem, or perhaps have an idea why I'm experiencing this annoying behavior? Thanx! P.S I realize this question might be more Visual Studio 2008 specific rather than programming specific, but I figure my best chance to find somebody that experienced the same problem would be at a forum for programmers (since naturally, programmers are the most frequent users of Visual Studio 2008).

  • Implementing search functionality with multiple optional parameters against database table.

    - by quarkX
    Hello, I would like to check if there is a preferred design pattern for implementing search functionality with multiple optional parameters against database table where the access to the database should be only via stored procedures. The targeted platform is .Net with SQL 2005, 2008 backend, but I think this is pretty generic problem. For example, we have customer table and we want to provide search functionality to the UI for different parameters, like customer Type, customer State, customer Zip, etc., and all of them are optional and can be selected in any combinations. In other words, the user can search by customerType only or by customerType, customerZIp or any other possible combinations. There are several available design approaches, but all of them have some disadvantages and I would like to ask if there is a preferred design among them or if there is another approach. Generate sql where clause sql statement dynamically in the business tier, based on the search request from the UI, and pass it to a stored procedure as parameter. Something like @Where = ‘where CustomerZip = 111111’ Inside the stored procedure generate dynamic sql statement and execute it with sp_executesql. Disadvantage: dynamic sql, sql injection Implement a stored procedure with multiple input parameters, representing the search fields from the UI, and use the following construction for selecting the records only for the requested fields in the where statement. WHERE (CustomerType = @CustomerType OR @CustomerType is null ) AND (CustomerZip = @CustomerZip OR @CustomerZip is null ) AND ………………………………………… Disadvantage: possible performance issue for the sql. 3.Implement separate stored procedure for each search parameter combinations. Disadvantage: The number of stored procedures will increase rapidly with the increase of the search parameters, repeated code.

  • Eclipc java,writting a program [closed]

    - by ghassar
    I have an important exercise for that i found in the internet please i need help in using eclipc java thanks i have to design, implement, test and document a Java program (a set of classes) for one of the following problem specifications: Problem 1 – Jubilee Estate Agency Property Management System A local Estate Agent would like a prototype system to keep track of properties that are offered for sale. The Estate Agent sells domestic and commercial properties. You will need to define classes that represent the Estate Agency System. You should design your system and the classes that you will need before starting coding. Your system must have a graphical user interface and be designed and developed using the object-oriented principles of the MVC architecture design pattern i.e. the user interface class must be separate from the other classes. The initial basic requirements for the system are as follows: • Include a list of domestic properties for sale that include details of: address, description, selling price, and number of rooms • Include a list of commercial properties for sale that include details of: address, description, selling price, and area in square metres • Enable the properties that are for sale to be viewed on the screen • Allow the customer to select one or more properties to be placed on a ‘viewing list’ so that the properties can be visited in person • Display on the screen the viewing list that shows the details of the properties chosen • Provide a basic search facility to find properties that are for sale in a particular price band and display the results • Enable a property to be marked as sold

  • Can a pc with a 1.2 ghz dual core run VS 2013? [on hold]

    - by moo2
    Edit: This question is about a tool used for programming, Microsoft Visual Studio 2013. I already read the minimum requirements for VS 2013 before I posted or I wouldn't have asked the question. I searched on the web for an answer for a few hours before posting. Why should I go out and spend $400 on a laptop if I can spend less than $100 and use it to learn how to program? In the context of the question it is clear I was not asking for advice on what laptop to buy and it was also clear I was not asking for someone to walk me through the system requirements of VS 2013. This is a vast community and I was wondering if someone in this vast community would have experience in dealing with my question. In other words has anyone ever tried anything like it? If I had an old computer sitting around I would have tested it. At the moment all I have is a friend's Chromebook I'm borrowing. End Edit. I know the requirements for Microsoft Visual Studio 2013 state 1.6 ghz processor. I'm looking at getting a laptop for school and I found one that is old but cheap and would work for college. The Dell D430 I'm looking at getting has a 1.2ghz Core 2 Duo CPU, 80GB HD, 2GB RAM, and Windows 7 Home Premium. It's refurbished. I can get it for less than most phone's cost and from a Microsoft Authorized Refurbisher. I know it's not a skyrim rig but it's lightweight and can handle being a college laptop and doing word processing. Would Visual Studio 2013 run at all? If it is slower I'm not concerned. I just want to know if it would work and compile my assignments and run them? I'd be using this laptop for doing assignments and learning programming languages not for coding the next social media sensation.

  • Are Visual Studio Setup Projects suitable for complex setups

    - by Robert
    Are "Visual Studio Setup" Projects suitable for complex setups in different versions? The application is rather large ( 500.000 lines of code) and is under continuous development. Every 6 to 10 month a new version gets released. We have multiple configuration files (INI and XML), registry keys, database migration scripts, etc. The application is in the progress of being migrated from VB6 to .NET . The old installer was build with Installshield. The feedback to Installshield is: Bad adaptability, bad reuse - thats way we are evaluating "Visual Studio Setup" as an alternative. Other products we consider: Free Solutions WiX NSIS Commercial Solutions Installshield (again..) Wise Advanced Installer sth. missing? Solutions we don't like to consider: Inno Setup (It just doesn't feel right)
