What is background build in Qt VS tools - visual-studio

Relates to Error while using Qt in Visual Studio 2019
I have the same error. Unfortunately I cannot still fix it, as Qt VS Tools for VS 2015 aren't updated. But my question is not how to avoid background build.
My question: what is background build?

Oh, I believe you are running into the 32767 names for this.
Let me preface this by stating that 2015 may have been the last time I used Visual Studio or developed anything for a Microsoft platform.
Part of your answer is in this discussion.
I believe the latest (or more current) name for "background build" is "live code compilation."
This is a resource robbing, highly annoying, syntax checking thing Microsoft thought would be great. It ranks right up there with Microsoft Clippy as far as tragic ideas go.
Basically, as you type, visual studio tries to build your stuff, puts squiggles under errors and generally consumes a whole lot of resources.
If you are using that Qt plug-in to build a QMake project this can cause all kinds of hardship, especially when you have UI files that need to MOC compile and are in the designer modifying the .UI file.
Whatever version of Visual Studio I was forced to use for that project, the first thing I did was find out how to turn that off.
Qt appears to not play well with Visual Studio it seems.
Here is a more complete description if you happen to have the plug-in.
BuildOnSave is an extension for Visual Studio 2019 and 2017 that
builds the current solution as soon a file is saved, and in
combination with the the extension SaveAllTheTime, enables a live,
background build experience while you type.

Can someone tell me the difference between visual studio and visual studio code? [duplicate]

Microsoft recently released Visual Studio Code and I am a little confused about its usage, since Visual Studio has lot of functional similarities with it.
Visual Studio (full version) is a "full-featured" and "convenient" development environment.
Visual Studio (free "Express" versions - only until 2017) are feature-centered and simplified versions of the full version. Feature-centered meaning that there are different versions (Visual Studio Web Developer, Visual Studio C#, etc.) depending on your goal.
Visual Studio (free Community edition - since 2015) is a simplified version of the full version and replaces the separated express editions used before 2015.
Visual Studio Code (VSCode) is a cross-platform (Linux, Mac OS, Windows) editor that can be extended with plugins to your needs.
For example, if you want to create an ASP.NET application using Visual Studio Code you need to perform several steps on your own to setup the project. There is a separate tutorial for each OS.
Visual Studio Code is an editor while Visual Studio is an IDE.
Visual Studio Code is cross-platform and fast, while Visual Studio is not fast.
Note that Visual Studio for Mac is available now but is a different product compared to Visual Studio (Windows). It's based on Xamarin Studio and lacks support for some older .NET project types. It does successfully build solutions created in Visual Studio 2017. Visual Studio for Mac has a more limited UI (for example, no customizable toolbar). So for cross-platform work, Visual Studio Code may still be preferable.
I will provide a detailed differences between Visual Studio and Visual Studio Code below.
If you really look at it the most obvious difference is that .NET has been split into two:
.NET Core (Mac, Linux, and Windows)
.NET Framework (Windows only)
All native user interface technologies (Windows Presentation Foundation, Windows Forms, etc.) are part of the framework, not the core.
The "Visual" in Visual Studio (from Visual Basic) was largely synonymous with visual UI (drag & drop WYSIWYG) design, so in that sense, Visual Studio Code is Visual Studio without the Visual!
The second most obvious difference is that Visual Studio tends to be oriented around projects & solutions.
Visual Studio Code:
It's a lightweight source code editor which can be used to view, edit, run, and debug source code for applications.
Simply it is Visual Studio without the Visual UI, majorly a superman’s text-editor.
It is mainly oriented around files, not projects.
It does not have any scaffolding support.
It is a competitor of Sublime Text or Atom on Electron.
It is based on the Electron framework, which is used to build cross platform desktop application using web technologies.
It does not have support for Microsoft's version control system; Team Foundation Server.
It has limited IntelliSense for Microsoft file types and similar features.
It is mainly used by developers on a Mac who deal with client-side technologies (HTML, JavaScript, and CSS).
Visual Studio:
As the name indicates, it is an IDE, and it contains all the features required for project development. Like code auto completion, debugger, database integration, server setup, configurations, and so on.
It is a complete solution mostly used by and for .NET related developers.
It includes everything from source control to bug tracker to deployment tools, etc. It has everything required to develop.
It is widely used on .NET related projects (though you can use it for other things). The community version is free, but if you want to make most of it then it is not free.
Visual Studio is aimed to be the world’s best IDE (integrated development environment), which provide full stack develop toolsets, including a powerful code completion component called IntelliSense, a debugger which can debug both source code and machine code, everything about ASP.NET development, and something about SQL development.
In the latest version of Visual Studio, you can develop cross-platform application without leaving the IDE. And Visual Studio takes more than 8 GB disk space (according to the components you select).
In brief, Visual Studio is an ultimate development environment, and it’s quite heavy.
Reference: https://www.quora.com/What-is-the-difference-between-Visual-Studio-and-Visual-Studio-Code
Visual Studio
IDE
Except for free editions, it is a paid IDE.
It is quite heavy on CPU and lags on lower end PCs.
It is mostly used for Windows software development including DirectX programs, Windows API, etc.
Advanced IntelliSense (best one ever; Visual Studio Code's IntelliSense extension takes second place)
It features built-in debuggers, easy-to-configure project settings (though developers tend to not use the GUI ones)
Microsoft support (more than Visual Studio Code)
Mostly used for C/C++ (Windows), .NET and C# projects along with SQL Server, database, etc.
Extreme large download size, space utilization and the slow downs over time.
It is the only con that forces me to use Visual Studio Code for smaller projects*
Includes tools to generate dependency graphs. Refactoring tools have great support for Visual Studio.
Has a VYSIWYG editor for VB.NET, C++.NET, and C#. (It is easy enough for first time users instead of getting through windows.h)
Visual Studio Code
Free open source text editor
Has IntelliSense (but it doesn't work out of box if Visual Studio is not installed, need to configure to point to MinGW, etc.)
Smaller download size and RAM requirements. With IntelliSense it requires around 300 MB RAM. (Edit : Some header files tend to blow up memory requirements to 7-8 GBs eg. OpenGL and GLM Libraries)
It works on lower-end PCs. (it is still slow to start up especially if PowerShell is used instead of CMD)
Lower support (open source, so you can modify it yourself)
Build tasks are project specific. Even if you want to build it in a vanilla configuration.
Mostly used for web development (this applies to all free text editors). They tend to show off JavaScript / HTML support over C/C++. Visual Studio shows off Visual Basic/C++ over other languages.
Lack of good extensions (it's still new though)
Gives you a hard time to reconfigure your project/workspace settings. I prefer the GUI way.
Cross platform
Has an integrated terminal (PowerShell is too slow at startup though)
It is best for smaller projects and test code (you know if you are bored and want to print "Hello, World!", it does not make sense to wait 3-5 minutes while Visual Studio loads up, and then another minute or 2 at project creation and then finally getting it to print "Hello, World!").
Complementing the previous answers, one big difference between both is that Visual Studio Code comes in a so called "portable" version that does not require full administrative permissions to run on Windows and can be placed in a removable drive for convenience.
For Unity3D users ...
VSCode is incredibly faster than VS. Files open instantly from Unity in VSCode. Whereas VS is extremely slow.
VS can literally compile code, build apps and so on, it's a huge IDE like Unity itself or XCode. VSCode is indeed "just" a full-featured text editor. VSCode is NOT a compiler: VSCode is literally "just a text editor".
With VSCode, you DO need to install in projects the "Visual Studio Code" package.
When you first download and install VSCode, simply open any C# file on your machine. It will instantly prompt you to install the needed C# package. This is harmless and easy.
Unfortunately VSCode generally has only one window! To open another window is a fuss.
In VS, it is all-but impossible to change the editor font, etc. In contrast, VSCode has FANTASTIC preferences - dead simple, never a problem.
As far as I can see, every single feature in VS which you use in Unity is present in VSCode. (So, code coloring, jump to definitions, it understands/autocompletes every single thing in Unity, it opens from Unity, double clicking something in the Unity console opens the file to that line, etc etc)
If you are used to VS. And you want to change to VSCode. It's always hard changing editors, they are so intimate, but it's pretty similar; you won't have a big heartache.
In short if you're a VS for Unity3D user,
and you're going to try VSCode...
VSCode is on the order of 19 trillion times faster in every way. It will blow your mind.
It does seem to have every feature.
Basically VS is the world's biggest IDE and application building system: VSCode is just an editor. (Indeed, that's exactly what you want with Unity, since Unity itself is the IDE.)
Don't forget to just click to install the relevant Unity package.
If I'm not mistaken, there is no reason whatsoever to use VS with Unity.
Unity is an IDE so you just need a text editor, and that is what VSCode is. VSCode is hugely better in both speed and preferences. The only possible problem - multiple-windows are a bit clunky in VSCode!
That horrible "double copy" problem in VS ... solved!
If you are using VS with Unity. There is an infuriating problem where often VS will try to open twice, that is you will end up with two or more copies of VS running. Nobody has ever been able to fix this or figure out what the hell causes it. Fortunately, this problem never happens with VSCode.
Installing VSCode on a Mac - unbelievably easy.
There are no installers, etc etc etc. On the download page, you download a zipped Mac app. Put it in the Applications folder and you're done.
Folding! (Mac/Windows keystrokes are different)
Bizarrely there's no menu entry / docu whatsoever for folding, but here are the keys:

Meta files ...
To keep the "Explorer" list of files on the left tidy, in the Unity case:
As of 2021 I believe the main differences are:
Visual Studio Code is a completely new codebase (based on Electron) than the "old" Visual Studio, it is open source and is actively developed "in the open" (on github)
Visual Studio is more focused on "traditional" Windows GUI apps development, and it is battery-included for that, including WYSIWYG programming style of the GUI ("visual")
Visual Studio Code, while pretty "nude" on its own, had attracted lots of community development for extensions to do the most crazy things. Community developed extensions exist to use it as a base for an integrated development editor for almost any programming language (for example I use it for Julia)
Out of the box, Visual Studio can compile, run and debug programs.
Out of the box, Visual Studio Code can do practically nothing but open and edit text files. It can be extended to compile, run, and debug, but you will need to install other software. It's a PITA.
If you're looking for a Notepad replacement, Visual Studio Code is your man.
If you want to develop and debug code without fiddling for days with settings and installing stuff, then Visual Studio is your man.
One huge difference (for me) is that Visual Studio Code is one monitor only.
With Visual Studio you can use multi-screen setups.
Visual Studio Code is for more of a pure code development tool while VS2019/VS2017 etc. is for more of a non-coding approach for developing programs. In VS you while get button tools and window toolbar tools and all that fancy stuff. In VSC you have to code the whole thing from scratch. I recommend VSC for people who are just learning to code but VS for advanced devs.
Visual Studio Code is integrated with a command prompt / terminal, hence it will be handy when there is switching between IDE and terminal / command prompt required, for example: connecting to Linux.
For me, Visual Studio on Mac doesn't support Node.js (editing and debugging) whereas Visual Studio Code does this very well.
In short, VSCode heavily promotes (Microsoft's) TypeScript compiler, and bundles first-class support for the language, which makes the editor web-centric, while Visual Studio is primarily used for Microsoft's native, C-family, Windows/XBox stuff.
As VS Code has been heavily developed every month, A new answer is worth.
I'm an ASP.net developer in Visual Studio for ten years. When I see in the Stackoverflow survey (https://insights.stackoverflow.com/survey/2021#section-most-popular-technologies-integrated-development-environment) that VS Code is the the first IDE of choice, I decided to give it a try by using it as my main develop environment, and here's the result after one month:
I can say if only VS Code has an scalable and stable intellisense like VS has, I would keep it as my first choice of IDE for dotnet. Omnisharp (VS Code C# intellisense) is satisfying for small projects but as the workspace becomes bigger (for example when you have more than one projects in your workspace) the instability starts to becomes a problem.
I still use VS Code for small dotnet projects and also as a DB Client, powershell ISE, python, etc. because of it's lightness, feature richness, customizability and having such an alive community and develop team.
obviously the situation can change by whether VS Code getting a VS-level dotnet intellisense, or VS get more game-changing features.

Avoiding merge problems when sharing solution between Xamarin Studio and Visual Studio

When sharing a solution between Xamarin Studio and Visual Studio, changes to solution/projects leads to unexpected results. The source text of the .sln/.project files has unexpected modifications, e.g.
UUIDs changed from lower to upper case
Reordering of lines in the .sln file
Changed "ToolsVersion"
Changed "Visual Studio" version
Other changes, like changing line break, changed "true" to "True", ...
This e.g. happens when changing the startup project, adding referenced projects, building the solution.
These changes lead to a "commit ping pong" between Xamarin Studio and Visual Studio users, and make merging harder. We experienced this problem with Xamarin Studio 5.5.4 and Visual Studio 2013 Update 4. The https://github.com/perpetual-mobile/SharingXamarinSolution repository contains examples. The http://forums.xamarin.com/discussion/comment/95851 thread also describes this issue.
How can this problem be avoided? Is it possible to prevent this from happening when using only Xamarin Studio and Visual Studio? Or do we need an additional tool (like e.g. cmake)?
One answer is to wait for version 6 of Xamarin Studio.
According to the bug report filed by Stephan Palmer, the issues raised above have been resolved in that version.
Are you seeing the same behavior if the project starts in Xamarin for Visual Studio versus Xamarin standalone versions?
The fastest workaround that comes to mind would be to use vcproj2cmake (uses Ruby)
http://sourceforge.net/projects/vcproj2cmake/
and use CMake scripting.
I highly recommend contacting Kitware and asking them for cross-compiling assistance - - they may already have a CMake script to resolve this issue since Xamarin is so popular.

Hope that helps,

Are there any functional differences between a VS2012 and VS2013 Solution?

The title of this question probably seems a bit convoluted so let me explain it in more detail.
I work for a company that has recently requested that all their pre-VS2013 Projects and Solutions be upgraded to VS2013. During my initial upgrade tests I noted that some of the solutions prompted for an Upgrade to be functionally sound under VS2013.
These Solutions/Projects typically launched the Migration Wizard and presented the message that non-functional changes to the Project were required to run under VS2013 and as long as there were no errors present afterward, the Projects compiled and ran without any issue.
While there were other VS2012 Solutions/Projects that displayed no dialogs whatsoever and simply ran under VS2013 without issue.
My initial presumption was since the latter mentioned Projects weren't identified by VS2013 as having any components that required alteration for the upgrade; that they were simply upgraded behind the scenes, compiled without error and simply ran.
But after a short conversation with the Company Supervisor and a peek at the Solution files, it appears that those Solutions are still configured for VS2012 and not VS2013.
Below are a few lines of code from each Solution File:
VS2013 Solution File
Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio 2013
VisualStudioVersion = 12.0.30110.0
VS2012 Solution File
Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio 2012
As you can see the VS2012 Solution File indicates # Visual Studio 2012 while the VS2013 Solution File shows # Visual Studio 2013 with an additional line appended to the file stating VisualStudioVersion = 12.0.30110.0
So the real question/concerns here regarding this migration effort are:
Is there any way to FORCE a VS2012 project to VS2013 as opposed to simply opening the project/solution under VS2013
Are there any potential caveats that should be taken into consideration when at some point VS2012 becomes outdated/deprecated by Microsoft? E.g. If tomorrow VS2012 were to become obsolete would there be potential areas of concern for these types of Projects running in a Production Environment?
The targeted goal is to have all our Projects and Solutions migrated to and running under VS2013 for continuity of the environment and simply do away with any Pre-VS2013 items.
Thanks
The ability to open projects created in earlier VS versions without converting them was first added to VS2012. By popular demand, moving to a new VS version could be pretty painful if not all members of a team migrated at the same time.
There is no point about fretting about this, VS2013 just doesn't have any trouble opening and saving projects like this. Nor does it have a way to force the conversion. In the olden days it could be done by running devenv.exe with the /upgrade option. Not sure if that still works, you'd have to try. I've seen SO users recommending editing the project file, I do not think that's a good idea.
It will automatically prompt you for an upgrade when you add any feature that wasn't supported in a previous release. Hard to come up with examples of that for VS2013, beyond Windows Phone 8.0 projects, VS2013 is a relatively minor increment from VS2012.

Register for COM Interop Always Runs in Visual Studio 2012

I have a solution with several projects that have Register for COM Interop checked.
I have a Visual Basic 6 project that references the resulting TLBs. One issue with VB6 is when it references a dll/tlb, it puts a lock on that file.
Using Visual Studio 2010, unless I'm doing a rebuild or have made a change to one of these interop projects, I can build/run the solution (with the VB6 project open) without it barking that one or more of the assemblies is locked.
However, using Visual Studio 2012, even on a simple build where nothing has changed, apparently it always does the regasm, which makes it impossible for me to debug my VB6 project.
Is this new feature of Visual Studio of running regasm on build something that I can turn off?
EDIT: Allow me to simplify:
Using Visual Studio 2010, I hit Build-->Build Solution and check the output for one of my assemblies that is marked as Register for COM Interop and the file has not changed.
Using Visual Studio 2012, I do Build-->Build Solution and check the same assembly, it has been updated, and does so every time I hit Build Solution.
I want the behavior in Visual Studio 2012 to work the same as it did in 2010.
EDIT (again):
I posted this to Microsoft Connect. If someone answers it there or posts a workaround, I'll urge them to also post the answer here.
I've always encountered problems like this when running VB6 and VS20XX, but I always did a rebuild. My suggestion is to stop using VB6 for testing purposes. I found it was far easier to simply create a testing project and do all of my testing in .NET on my .NET code. This should only require a small amount of set up, but it is well worth it in my opinion.
I know this isn't an answer to your specific question, but it offers an alternative. As far as the problem you are describing, I can't duplicate a change in behavior. I start off with only VS201X open, full solution rebuild, open VB6 and add a reference to an exposed COM DLL. I didn't notice anything unexpected.
Build works fine as long as I haven't changed anything in the COM DLL
Build fails if I changed the COM DLL's code as the file is locked
Rebuild fails as the file is locked

Python Triple Quoted Strings in Visual Studio 2010

I'm used to using Idle for Python development, but decided to give Visual Studio 2010 + IronPython a try last week. It seems to work fine, but I noticed that triple-quoted (multi-line) strings don't highlight correctly in the editor. See photo:
Does anyone else have this problem or know of a good fix? Apart from that bug, Visual Studio seems to be great for Python.
This is a bug that is already fixed for the next release - I screwed up storing our state while processing line-by-line when fixing another bug.
If you're really anxious you can actually build the MSI which includes the tools from the sources on CodePlex. Once you have the VS SDK installed it should be as simple as running Scripts\Bat\Dev.bat to setup the enlistment environment and then msbuild Msi\Installer.proj which will produce an MSI in Bin\Debug.
