  • How can I make VS2010 insert using statements in the order dictated by StyleCop rules.

    - by Hamish Grubijan
    The related default StyleCop rules are: Place using statements inside namespace. Sort using statements alphabetically. But ... System using come first (still trying to figure out if that means just using System; or using System[.*];). So, my use case: I find a bug and decide that I need to at least add an intelligible Assert to make debugging less painful for the next guy. So I start typing Debug.Assert( and intellisense marks it in Red. I hover mouse over Debug and between using System.Diagnostics; and System.Diagnostics.Debug I choose the former. This inserts using System.Diagnostics; after all other using statements. It would be nice if VS2010 did not assist me in writing code that won't build due to warnings as errors. How can I make VS2010 smarter? Is there some sort of setting, or does this require a full-fledged add-in of some sort?

  • .NET Application with SQL Server CE Database

    - by blu
    I just started using SQL Server CE 3.5 in my WinForms Application (C# in VS 2008 SP1). I've noticed a couple of interesting things I'd like some input on: 1. Copying of sdf file to bin My sdf file is located inside of an Infrastructure project that houses my repository implementations. When the application is first debugged the sdf was copied to debug\bin. This is where all future reads/writes operate. At some point when this is deployed the file will go into a data folder using Click Once, but during development where should I be putting this sdf? Is having it in the bin typical, or are there any other recommendations? 2. Updating sdf It appears that writing to the sdf file does not immediately update the database. I am using Linq-to-SQL and am calling SubmitChanges, but on read the values are not returned. However if I close the application and re-open it the added value is there. Is there an additional flush step I need to take? What is causing this, file locking, buffering, something else? Update 3. Unit Tests I have an MS test project, and the sdf file is not being copied to the correct output directory. I have the settings: Build Action: Content Copy to Output Directory: Copy Always The message is: System.Data.SqlServerCe.SqlCeException: The database file cannot be found. Check the path to the database. I appreciate any guidance on these questions, thanks. If there is a tutorial other than what is on MSDN that you know about that would be great too. Working with CE is proving to be a difficult task and I welcome any help I can find.

  • What /else/ causes this?

    - by Mordachai
    MFC Toolbox Library.lib(SimpleFileIO.obj) : error LNK2005: _wcsnlen already defined in libcmtd.lib(wcslen_s.obj) fatal error LNK1169: one or more multiply defined symbols found This is driving me nuts. Normally, one would get this if the various projects that are a part of their solution do not agree on which CRT to use (single threaded, multi-threaded, release or debug). However, I have been over this thing about 500 times now, and they all agree. Background: this is a VS 2010 project just converted from VS 2008. MFC Toolbox Library.lib is set to compile as a static library, using /MTd, as is the target .exe I am trying to compile in this solution. Further, the solution that this is being converted from (VS 2008) already compiles & links properly!!! So it's not like that there is a disagreement between the two .vcproj's - or at least there wasn't before the conversion. Furthermore, the MFC Toolbox Library is used by about 25 other projects in another solution - and in that solution (Master Build English) it compiles & links against those other projects without complaint in both debug and release targets. I have just spent the last hour going over every single project property for this target project (Cimex Header Viewer) vs. several different target exe projects in Master Build English solution - and I cannot find a difference. They appear to be identical, excepting that they're different names. I've tried doing a clean & build all. I'm simply out of ideas. Does anyone have a thought on what else I might investigate??? I think I'm ready to start chewing glass. :(

  • Nested for_each with lambda not possible?

    - by Ela782
    The following code does not compile in VS2012, it gives error C2064: term does not evaluate to a function taking 1 arguments on the line of the second for_each (line 4 below). vector<string> v1; for_each(begin(v1), end(v1), [](string s1) { vector<string> v2; for_each(begin(v2), end(v2), [](string s2) { cout << "..."; }); }); I found some related stuff like http://connect.microsoft.com/VisualStudio/feedback/details/560907/capturing-variables-in-nested-lambdas which shows a bug (they are doing something different) but on the other hand that shows that what I print above should be possible. What's wrong with the above code?

  • VS2005 and VSS. Should .exes, .dlls, pdbs, .resource and generated .xml files go in VSS?

    - by Velika
    It seems like the following type of files need to be writable to be able to compile a solution. .exe .dll .pdb (if debugging) .resource (?) .xml (at least the system generated ones. I'm not sure if they are just all XML documentationf iles) If they were checked in and could only be overwritten by the compiler by the person who had them checked out, then checking them into sourcesafe and requiring a checkout to modify them, which is attemtped by the compiler each time you run, would interfer with other developer's ability to debug and run. What is the best practice? It seems like VSS automatically adds everything.

  • Why are some C#4 features allowed even when targeting 3.5?

    - by Greg
    We upgraded to VS 2010, but we haven't yet upgraded to .NET 4.0. All of our projects are still explicitly targeting 3.5. Today, a developer checked in code that looked like this: delegate T Generator<out T>(); As far as I know, "in T" and "out T" are C# 4.0 features. According to our build server, which doesn't have .NET 4.0 installed on it, I'm right. The check-in broke the build. But, why the heck does it build on his machine? Why is VS just ignoring the target framework for the project? Other C# 4.0 features, like the dynamic keyword, do not build on the developer's machine.

  • VSS Deprecated Files

    - by timothyawiseman
    We are using VSS for version control (changing to another version control system is not an option right now), and are occassionally running into issues where a file has been completely deprecated with its functionality split into other new files. For historical archival reasons we need to keep those files in the version control sytem. Is there some way to clearly mark them as deprecated and no longer used?

  • C++ Array vs vector

    - by blue_river
    when using C++ vector, time spent is 718 milliseconds, while when I use Array, time is almost 0 milliseconds. Why so much performance difference? int _tmain(int argc, _TCHAR* argv[]) { const int size = 10000; clock_t start, end; start = clock(); vector<int> v(size*size); for(int i = 0; i < size; i++) { for(int j = 0; j < size; j++) { v[i*size+j] = 1; } } end = clock(); cout<< (end - start) <<" milliseconds."<<endl; // 718 milliseconds int f = 0; start = clock(); int arr[size*size]; for(int i = 0; i < size; i++) { for(int j = 0; j < size; j++) { arr[i*size+j] = 1; } } end = clock(); cout<< ( end - start) <<" milliseconds."<<endl; // 0 milliseconds return 0; }

  • Build Event Macros for Other Projects in the Solution

    - by Adam Driscoll
    Is it possible to reference other projects' properties via a macro within a build event? For example: "Tool1" outputs to directory ..\..\bin\Release "Component1" uses "Tool1" in its post-buildevent To get to "Tool1", "Component1"'s project must do something like $(SolutionDir)bin\Release This requires that Tool1 always output to ..\..\bin\Release. If this is changed this breaks the other project. I know there is no indication to this within the macro list but is there a way to reference another project? Maybe like $(OtherProject.TargetDir)... I know WIX has a similar syntax [$(var.OtherProject.TargetDir)] but I think that may be a different mechanism.

  • Magick++ in VS2010 - unresolved external symbol

    - by FlashFan
    Hey guys! I'm trying to use ImageMagick Magick++ for a C++ Project in VS2010. I installed the Library from here: klick Then in my Project, I added c:/program files/ImageMagick-6.6.6-Q16/include to the include folders.

  • Can't get GetModuleFileNameA to work, keep getting error 'missing type specifier...'

    - by flavour404
    Hi, I am trying to use 'GetModuleFileNameA' but I keep getting the error 'c4430: missing type specifier - int assumed'. From reading the results from my google search I am guessing that it is from my use of NULL: char Filename[MAX_PATH]; //this is a char buffer GetModuleFileNameA(NULL, Filename, sizeof(Filename)); NULL is supposedly defined in #include stdio.h which I have included in my project, what am I doing wrong? Thanks.

  • Can't catch newConnection() signal from QTcpServer

    - by Bob
    I am trying to make a simple server thread in QT to accept a connection, however although the server is listening (I can connect with my test app) I can't get the newConnection() signal to be acted on. Any help as to what I'm missing here would be much appreciated! class CServerThread : public QThread { Q_OBJECT protected: void run(); private: QTcpServer* server; public slots: void AcceptConnection(); }; void CServerThread::run() { server = new QTcpServer; QObject::connect(server, SIGNAL(newConnection()), this, SLOT(AcceptConnection())); server-listen(QHostAddress::Any, 1000); // Any port in a storm exec(); // Start event loop } void CServerThread::AcceptConnection() { OutputDebugStringA("\n***** INCOMING CONNECTION"); // This is never called! }

  • Debugging ASP.NET in VS

    - by negligible
    A lot of what I'm doing at the moment is figuring out other peoples code and adding or adapting functions, so currently I am debugging more than I am writing code of my own. I'm still new to this, Junior Developer, and I am always finding new ways to improve what I am doing. For example I recently found This Guide which had some excellent tips, such as overriding the ToString() method in your classes so children are readable from their parents. So I am looking for any other tips or tricks to make my debugging more efficient, as I recognise it as a big part of programming, that you more experienced programmers may have picked up or found. Anything appreciated, I can read websites just fine so no need to explain it yourself if you have a good link!

  • Startup params for Silverlight 4 app

    - by Number8
    Hello -- We are moving our SL3 app to SL4. First step was to open it in VS2010; it converted w/o problem. However, parameters specified for the start page are not passed along. That is, if we specify ourStartPage.aspx?Slam=Dunk&Glass=Sun in app.xaml.cs, Application_Startup(), e.InitParams is empty. How do we fix this? Thanks for any advice.... (Note that the very same startup string worked in VS2008.)

  • Anyway to find out the current Windows is in lock mode?

    - by David.Chu.ca
    I have a windows application written in VS 2005. The application makes queries against to sql database in a timer cycle every 2 minutes. If there any data changes, the window will be refreshed with new data. If the user leaves the window, the windows will be automatically locked after a while. There is no sense to keep querying data in ever 2 minutes when the windows is locked; therefore I would like to stop the query when lock is on so that the network data trafic will be reduced and also saves the current windows resources such as memory and CPUs. I am not sure if there is any way to find out the current windows is locked? Not sure if there is any Windows APIs for this purpose if no .Net classes available? My project is in .Net 2.0 and all users are in Windows XP.

  • How to close a form in UserControl

    - by FJPoort
    I created a UserControl with the buttons Save, Close and Cancel. I want to close the form without saving on the Cancel button, prompt a message to save on the Close button and Save without closing on the Save button. Normally, I would have used this.Close() on the Cancel button, but the UserControl doesn't have such an option. So I guess I have to set a property for that. Scrolling down the "Questions that may already have your answer" section, I came across this question: How to close a ChildWindow from an UserControl button loaded inside it? I used the following C# code: private void btnCancel_Click(object sender, EventArgs e) { ProjectInfo infoScreen = (ProjectInfo)this.Parent; infoScreen.Close(); } This does the job for one screen, but I wonder if I have to apply this code for all the screen I have? I think there should be a more efficient way. So my question is: Do I need to apply this code for every form I have, or is there another (more efficient) way?
