That's pretty much my question: can VS 2010 check and update header files in C++ code automatically? And can VS 2010 automatically generate a cpp file from a header file, saving you the time to copy the function definitions from the header file? I mean, can it figure that there's no implementation for some method and generate an empty stub from the declaration found in the header file?
Thanks!

No this feature does not exist in the Visual Studio C++ implementation. Changes to a header file must be manually propagated to the source file and vice versa.

I have cloned a repository and Visual Studio is showing hundreds of errors in all of the header files due to them not #include-ing all of their used dependencies, even though the solution builds just fine. From what I understand, this is because header files do not need to include everything they use as long as they themselves are included after their dependencies in the files where they are used.
When I asked the repository owner about this they said that this is a bug that was not present in previous Visual Studio editions, therefore meaning that there should be a way to make Visual Studio treat all the identifiers not included in a header as actually included.
I found that main.cpp includes every header and in the correct order, ensuring that even if a given header doesn't include all that it uses it will still compile just fine. Is there a way to make Visual Studio keep track of all the previous includes from the frame of reference of main when in a given header, therefore preventing all the identifier ... undefined errors inside the headers?
EDIT: It seems that the files aren't getting scanned by Visual Studio for some reason, as when I manually open files and pin them, the errors start going away. Is there some way to force Visual Studio to automatically consider the entire solution at once instead of having to open every single header?
Does Visual Studio 2015 Community edition have a method to print out names of functions in a file. I have a program of 3000 lines of code and want to put related functions into seperate header files. I want to make sure that the header and its related .cpp file has same functions.
I don't want to end up putting functions in wrong header or source file and am trying to think the best way to do this.
i just started learning c++ lately and i am using visual studio 2015. But i have to manually remove the #include stdafx.h in my cpp file before upload it to the test server for my class, or it just sends back an error like this:the error from test server
I would like to know why this issue is happening. My guess is that this thing is exclusive to windows and x86 based OS?
Any help would be appreciated. :D
You'll need to upload all your sources. stdafx.h isn't special in that regard. Of course, if your course restricts you to one .cpp upload, then you can't use stdafx.h for that course
stdafx.h is the default name of a precompiled header for a Visual Studio project. However, you can certainly have a file named this on other environments. Note that the Visual Studio compiler processes this header slightly differently than it does other headers, if it is specified as the precompiled header in your project's property pages (C/C++ -> Precompiled Headers - see here for more details). For example, multiple includes of this file with different preprocessor defines will be ignored when it is the precompiled header (which isn't that common, but something to be aware of).
If you want to make portability to non-Visual Studio environment easier, it's usually easier to disable precompiled headers in your Visual Studio project. If you continue to use the stdafx.h file in your code, you will obviously need to upload it to your test compilation server, and may need to modify it and/or its inclusion into your code.
Every time I create headers I have to manually rename their extensions from .h to .hpp.
And when I create C++ Projects with wizards, header files get created with the .h extension.
Is there any way to change C++ Headers' default file extension in Visual Studio 2013?
I know, it's a matter of personal preference, but I want to do it anyway.
The Visual Studio world uses ".h" extension, that's just the way it is and it makes no difference whatsoever the extension you use. They all become part of your ".cpp" files anyway when the are "included", they are literally copied in in-place of the "#include" line when the compiler runs. They can have any extension at all. It also doesn't matter if the source files are ".c" or ".cpp", the compile mode is set in the project properties, and will be C++ unless you deliberately change it, which would render most of the SDK unusable anyway.
I have folder contain a Visual Studio project and contain lots of .h and .cpp file I want to put all of this .h and .cpp file into just one main.cpp file is there any way to do that with Visual Studio or any other things??
Depending on the functions and libraries you are using it can/can't be done. if all the functions are compilable in Turbo and the project isn't that professional which I think it isn't based on you saying you want it for your course project you can simply copy everything in a cpp and convert the header files into simple classes. anyway Turbo C++ is Dead!
You cannot do this trivially. You would have to refactor, as merging source files can introduce semantic problems. It's best to not do this at all.
