• How to use the new VS 2010 configuration transforms and apply them to other .config files?

  - by Wallace

  I have setup some configuration transforms in my web.config for my connectionStrings, etc. But I have separated out some areas of my web.config into separate files, ex) appSettings.config. How can I configure Visual Studio and MSBuild to perform config transformations on these additional config files? I have already followed the approach of the web.config to relate the files together within my web application project file, but transformations are not automatically applied. <ItemGroup> <Content Include="appSettings.Debug.config"> <DependentUpon>appSettings.config</DependentUpon> </Content> </ItemGroup>

• How to set up source control in VS2010

  - by Jouke van der Maas

  Hi, I want to set up source control for my project, but it seems like I need a server for this. I've never done this before, and I couldn't find anything helpfull yet. Is there any way to host a server locally so Visual studio can use it? Or do you know any online (free) servers I can use? By the way, if source control is not actually what i should use for keeping track of changes in my files, please suggest a better option. Thanks in advance.

• Problem setting up Direct X for C++

  I've downloaded Direct X SDK from the microsoft website but when I try to compile my code i'm getting this error: Error 1 error LNK2019: unresolved external symbol _Direct3DCreate9@4 referenced in function "void __cdecl initD3D(struct HWND__ *)" (?initD3D@@YAXPAUHWND__@@@Z) C:\Users\Josh\Desktop\Tutorial\Tutorial\Tutorial.obj Tutorial I have added Direct X to my C++ build directories like that: $(DXSDK_DIR)include $(DXSDK_DIR)Lib\x64 I've googled it and found out that most of the time people were forgetting this line: #pragma comment (lib, "d3dx9.lib") But it's there for me here are my includes and lib: #include <windows.h> #include <windowsx.h> #include <d3d9.h> #include <d3dx9.h> #pragma comment (lib, "d3d9.lib") #pragma comment (lib, "d3dx9.lib") Can anyone help me with this?

• Killing a program if it displays a dialog box (devenv.com running under CruiseControl.net)

  - by Alan Mullett

  I have CruiseControl.net running Visual Studio (2005/2008 - using devenv.com) as we need to build deployment projects (.vdproj). At times, for various reasons devenv decides that even though it was run from the command line, using the devenv.com varient, it still wants to put up a dialog box. Now, as it's running under CruiseControl.net on a remote server this is never seen and the only syptom of this is that the build eventually times out. When the build is still in progress a look at the tasks shows devenv running but not consuming any processor power. Is there a handy utility through which could run devenv.com which basically watches the program it starts up and basically kills it if it dares to display a dialog box of any kind?

• How to build a C++ Dll wrapper that catches all exceptions?

  - by bart de vries

  Like the title says, we’re looking for a way to catch all exceptions from a piece of C++ code, and wrap this in a dll. This way we can shield of the application that uses this dll, from any errors occurring in this dll. However, this does not seem possible with C++ under Windows. Example: void function() { try { std::list<int>::iterator fd_it; fd_it++; } catch(...) {} } The exception that occurs is not caught by the standard C++ try/catch block, nor by any SEH translator function set by _set_se_translator(). Instead, the DLL crashes, and the program that uses the DLL is aborted. We compiled with Visual C++ 2005, with the option /SHa. Does anyone know if it’s possible in C++/Win32 to catch these kind of problems and make a rocksolid DLL wrapper?

• Why my custom CStatic derived control does not receive WM_SIZE message?

  - by Michael P

  Hello everyone! I'm currently developing a custom control that derives from CStatic MFC class (Smart Device C++ project). I have created the control class using VC++ MFC class wizard, selecting CStatic class as its base class. I have used Class View to add OnSize event handler for my control class (I have selected WM_SIZE message from messages list), and new OnSize method has been created by Visual Studio along with ON_WM_SIZE() statement between BEGIN_MESSAGE_MAP(...) and END_MESSAGE_MAP(). The problem is that my control does not receive WM_SIZE thus OnSize method is never called - I used MoveWindow to change size of my control - its size changes as I have seen on dialog window but WM_SIZE message is never being sent. When I send WM_SIZE through SendMessage or PostMessage function - the control OnSize method is called normally. What do I wrong? I've read MSDN docs about CStatic control and there is no information that WM_SIZE message is never sent to a static control window. Sorry for my bad English.

• .NET Application using a native DLL (build management)

  - by moogs

  I have a .NET app that is dependent on a native DLL. I have the .NET app set as AnyCPU. In the post-build step, I plan to copy the correct native DLL from some directory (x86 or AMD64) and place it in the target path. However, this doesn't work. On a 64-bit machine, the environment variable PROCESSOR_ARCHITECTURE is "x86" in Visual Studio. My alternative right now is to create a small tool that outputs the processor architecture. This will be used by the post-build step. Is there a better alternative? (Side Note: when deploying/packaging the app, the right native DLL is copied to the right platform. But this means we have two separate release folders for x86 and AMD64, which is OK since this is for a device driver. The app is a utility tool for the driver).

• How do I fix "error 1004, 0, Unable to find property" in an Entity Framework 4 WinForms application?

  - by Ivan

  I've designed an EF4 model (quite complex inheritance, lots of small tables incl. multiple self-referencing), generated (table-per-type) a database and inserted some basic data manually. It works fine in an ASP.Net Dynamic Data Entities web application with full automatic scaffolding. But when in a WinForms application using the same model (I share it as a part of a class library) I construct a query and bind a combo box to it (the way it's shown here), I get an InnerException {"Internal .NET Framework Data Provider error 1004, 0, Unable to find property... I've found a question about the same problem here (incl. a sample to reproduce the error) but no answer. I use final Visual Studio 2010, no beta.

• Naming Optional Parameters in VSB

  - by SteveNeedsSheetNames

  In Visual Basic, I have Functions with a lot of Optional arguments. I would like to be able to pass just a few of these Optional arguments to a Function without having to use numerous commas and spaces to get to the ones I want. Somewhere I saw a way to name params such as OptVar:=val, but that does not seem to work. Just wondering if there is a way to do this. This would help readability. Thanks in advance for the replies.

• What is a good method to use with multithreading to simulate this?

  - by user1504257

  I am writing a program in c++ in visual studio to be able to handle a line at a park. I have all of my customers in a line at the park and I want to be able to service them using multithreading with openmp. When I put the pragma and such in, I have multiple threads servicing the same customer at the same time for each and every customer I create, not what I want. I want for example, if I had two threads and four customers, that thread one to do customer one while thread 2 does customer 2. Then I would like thread 1 to do customer 3 and thread 2 customer 4 at the same time. I don't know if its possible or if there is a better way, but I need to use openmp. Thanks for your input.

• Symbols taking very, very long time to load when hosting ASP.NET app in IIS

  - by joshcomley

  Hi, I'm hosting my project using IIS, running from Visual Studio. Whenever I recompile, on the first run it takes several minutes (on a not awful machine) to load all the symbols. Please see http://joshz.com/so/symbols.html for a list of the symbols that are loaded. At the bottom there is a ThreadAbortException, I'm not sure if this is playing a role. Any advice would be greatly appreciated; it's slowing my day down enormously! As a note: the project has never run quickly since I joined the company and started working with it.

• How to use a different assembly name for different configurations?

  - by Mark Ingram

  In Visual Studio 2008 (and others) when creating a .NET or silverlight application if you look at your project properties, it seems like you can only have one assembly name - across all configurations. I would like to compile my application as: MyAppDebug - in debug mode and just MyApp - in release mode Does anyone know if this is possible? Edit: It seems some people are questioning the reasoning behind the question, so I'll explain a little further: I'm working on a Silverlight application which gets automatically uploaded to our test site when I to a "build solution". The trouble is, the test team are now testing the online version, whilst I work on a new one. So, I want to have a url like .\MyApp.html for the regular version that the QA team will test and then .\MyApp.html?version=debug for the current version that I'm working on.

• Is there a efficient way to do multiple test cases in c?

  - by Ahmed Abdelaal

  I use MS Visual Studio and I am new to C++, so I am just wondering if there is an faster more efficient way to do multiple test cases instead of keep clicking CTRL+F5 and re-opening the console many times. Like for example if I have this code #include <iostream> using namespace std; void main () { int x; cout<<"Enter a number"<<endl; cin>>x; cout<<x*2<<endl; } Is there a way I could try different values of x at once and getting the results together? Thanks

• VB.Net 2008 Chrome or Firefox control

  - by AndyD273

  I'm trying to figure out a way to have multiple sessions at the same website at the same time. I've been using the SHDocVw.InternetExplorer control in Visual Studio 2008 to open a web browser and log in, but at times we need to use a separate login. I haven't found a way to do this using just internet explorer (it just uses the credentials of the first login), so I figure if I can find a similar control for another brower that allows DOM level access then I can just use that. If anyone knows of anything I can try that would be very helpful.

• ClickOnce disallow publishing of Debug builds

  - by LnDCobra

  Is there anyway to disallow publishing Debug builds when publishing ClickOnce aplications using Visual Studio 2008? I know this was asked before, but i can't figure out how from the answer. THe Accepted answer for previous question was: One thing you can do is add a condition to the .csproj or .vbproj file that MSBuild will check when doing a build. The condition would check if a publish is occurring and check if the build is a debug build, then do something like run an external tool or otherwise interrupt the build process or cause it to fail. Could anyone elaborate on that answer or tell me where/or how I can add this condition. [Original Question][1] [1]: http://One thing you can do is add a condition to the .csproj or .vbproj file that MSBuild will check when doing a build.

• .Net Designer assemblies, C++\C# error

  - by greggorob64

  I'm working on an designer-heavy application (using Visual C++ 2.0, but a C# solution should still be relevant). My setup is this: I have a UserControl named "Host" I'm attempting a UserControl named "Child" Child contains a property to a class whose type is defined in a different dll entirely, named "mytools.dll" Child works just fine in the designer. However, when I go to drag "child" onto "host" from the designer, I get the following error: Failed to create component 'Child'. The error message follows: 'System.io.filenotfoundexception: could not load file or assembly MyTools, Version XXXXXX, Culture=neutral ..... {unhelpful callstack} If I comment out the property in "child" that points to the class in mytools.dll, everything designs just peachy. I have the property marked with "Browsable(false), and DesignerSerializable(hidden), and it does not help. Is there a way for me to explicitly say "Don't load this dll, you won't need it in design time", or some way for me to force a dll to load from the designer programmatically? Thanks!

• When to use MVC Scaffolding via NuGet vs MVC Scaffolding via MVC3 Tools Update

  - by James

  I am a little confused about the various different "mainstream" scaffolding options for MVC3. There is a NuGet package called MVCScaffolding. It first showed up in Jan 2011, but seems to be active and have recent updates, and be developed by Scott Hanselman, among others. Then in May 2011 came the MVC3 Tools Update. This seems like it incorporated the original scaffolding ideas into an "out of the box" scaffolding options. However, this has not been updated since. So - what is the relationship between these two scaffoldings (if any). Are there cases when one should be used over the other, or is it just a matter of taste? Does Visual Studio 2012 or MVC4 change the game on any of this? Thanks for any input.

• What VS Projecttype for Model and Database?

  - by Tim

  Hello folks, i've just started a new asp.net project which could increase fastly(a small erp-system for our company). So i thought it would be a good idea to split at least the model from the view/controller(the asp.net project). Because it could be that i need to access some classes and the database from a windows app in future, i dicided to put the Model into its own Project. What Visual Studio 2005 Professional Projecttype is most suitable for this requirement and why? SqlServerProject (DB is MS Sql Server 2005 EP) Class Library Web Service Application Database project no separate Project/other(keep in mind VS 2005 has no ASP.NET MVC-Project) Thanks

• How to change position of inherited items in an Inherited user control

  - by Yalda

  I have used a user control as a base class (let's call it BaseUC) with 3 labels (in 3 lines) on it (they are set as protected). And there is another user control that inherits from it (InheritedUC). I have added two more labels in InheritedUC, which are positioned between the base's labels (so there are 5 lines). Everything is fine is Visiual Studio's design UI view. But when I run the application, labels on BaseUC overlap with the ones in InheritedUC and I can't see the ones on the inherited control. Any ideas to fix this? Thank you very much

• Platform configuration for projects in VS 2010

  - by Thomas Wanner

  I have a third-party project type in Visual Studio which for some reason only supports the .NET Platform configuration for the build, for all other (standard C#) projects in the solution I only have AnyCPU. Unfortunately, ever since upgrading to VS 2010 it produces following error when built : Error 39 The OutputPath property is not set for project 'ReferencedBusinessProject.csproj'. Please check to make sure that you have specified a valid combination of Configuration and Platform for this project. Configuration='Debug' Platform='.NET'. This error may also appear if some other project is trying to follow a project-to-project reference to this project, this project has been unloaded or is not included in the solution, and the referencing project does not build using the same or an equivalent Configuration or Platform. C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets 483 10 CustomTypeProject It's pretty much descriptive in what is missing but I haven't found any way to fix it so far. Do you have any idea how this can be resolved or what can be the problem ?

• ASP.NET 4 UpdatePanel and IIS7 Problem

  - by rwponu

  I have an ASP.NET 4 webpage that contains an update panel which just allows me to add a few items to a drop down list without reloading the entire page. The page works fine on the Visual Studio 2010 ASP.NET Development Server, performs the Async call and the page is properly laid out. However, when I deploy the page to IIS7, the Async call no longer works (the page is completely reloaded) and the layout of some items on the page is incorrect. I used Fiddler to look at what's happening and it looks like there are 404's when the page tries to access ScriptResource.axd, with everything else working correctly. I think that has to do with the Javascript required for the call but I'm not sure how to fix it. Any suggestions?

• How do you add folder level documentation to C# assemblies?

  - by Elijah

  Me: I'm a relative new-comer to the .NET platform. Problem In Java, you can add package level documentation to your project by creating a package-info.java or package.html file and storing in the package folder. How do I add equivalent documentation to my project in C# using Visual Studio 2010? Background I like to write documentation describing my motivations in the package/folder level context of the source code projects that I am working on. I have become very accustomed to this workflow in a variety of languages (specifically Java) and I believe that it is a good way to document my project.

• Using Gradle with an existing Android project

  - by Tom Reznik

  I have an existing Android project with the following structure: - ProjectName -- AndroidManifest.xml -- local.properties -- project.properties -- assets -- libs (containing all jars) -- modules (containing all library projects my project depends on) -- res -- src ---- com/namespace/projectname (all my classes including main activity are here) I haven't been using any specific build system to build my project other than the one provided by default with the Android Studio IDE (though the project was originally created with IntelliJ CE. I would like to use Gradle with the android plugin and do some work on my build process. I have tried several configurations in order to achieve this and have failed to complete a successful build every time. What's the recommended approach in this scenario? should I change my project structure? or is it possible to configure gradle using the existing structure? Any help would be greatly appreciated. Thanks!
