Is there a way to specify include directories in the code, perhaps via a #pragma?
I have my project setup as "src/" and "include/" folders. I am trying to compile in Visual Studio 2010, but I don't want to set it up in the project settings.
Is there another way to allow it to compile instead of having to specify the include as
#include ../include/ss.h
The Correct(tm) way to specify search directories is with compiler flags. In Visual Studio you do this by playing with the project settings, or its compiler's /I commandline parameter.
In Visual studio, you can also define include folders by setting them via Options/File Locations. Then you don't need to repeat them in every project setting. (Assuming that's what you're after). It is a bit weird to define absolute paths in source code, you'll never know from which folder/drive a build is run.

when using the intellisense prompt of VS2022 to automatically include the header file in the code in the Cpp file, the following error always occurs
#include "../Config/UGConfigManager.h"
Is there any way to replace the path "../" with a full path? Like this:
#include "Game/Config/UGConfigManager.h"
EDIT:
In UE5, you need to change NMake's IncludeSearchPath instead of VC++ Directories in Properties -> NMake
You need to add an include path to the "Game" folder.
To set an include path you now must right-click a project and go to:
Properties -> VC++ Directories -> General -> Include Directories
Then add the include directory like so:
C:/foobar/Game
First try using an absolute path. And if that works you will want to use a Macro. Macros allow users to define paths without being specific to their own computer (So other people can use it).
Perhaps what you need is $(ProjectDir) but I can't tell since I don't know where "Game" is relative to your project files.
But as an example:
$(ProjectDir)/Game
It's worth pointing out that what you are doing is interacting with the compiler option /I on the MSVC compiler. Visual Studio is just a gui abstracting it away for you.
Here are the docs on /I (Additional include directories)
This may be a very simple question but I haven't been able to figure it out so any help is appreciated.
I have a header that is located in a general folder because I want to use it in several projects for example:
C:\user\geninclude\program\header.h
I created a new empty project with a very simple main, in the main I put
#include <program/header.h>
I then went to the project properties and in VC++ in include directories added C:\user\geninclude\
but when I tried to build the program the program tells me it cannot find header.h because is not in the current directory or in the build system path.
I also tried in the project properties in C/C++ general Additional Include Directories adding C:\user\geninclude\ but still the same error.
I know is something simple I am missing, but I don't know what, I am very new to this just learning.
For reference I am using Visual Studio 2013.
Thank you in advance for your help.
UPDATE: Thank you all for your kind responses, I have tried everything you have told me (check release vs debug in both instances, change / for \ and <> for "", and double checking the header and still the system does not see it. It really is very weird. I'll keep trying...
Please check if your file is really an header file otherwise it won't appear on include.
What you can also do (as a workaround if you need that method fast) is to put your header file (or folder with header files) on the visual studio "include" folder. The path should look like this "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include"
PS: You should also check the properties configuration when you're adding the path to VC++ include directories. You could be adding the path to debug configuration and trying to run it in release mode.
You do indeed want
Project Properties -> Configuration Properties -> C/C++ -> Additional Include Directories
(or something close to that; I'm using VS 2008). Make sure the configuration you're editing in the top left (debug/release) matches the configuration you're building with (typically visible up top in the main window). So it sounds like you may have done it correctly; I'd double-check for the file's existence in that location. You could also try program\header.h instead of program/header.h. If none of those work, try adding C:\user\geninclude\program to the include directories (no \ at the end) and change it to #include "header.h". If that doesn't work either, you've almost surely got the header file in the wrong spot.
Another thing that can cause include files not being picked up is a difference between the platform set in your c++ project's Property Pages and your "Active Solution Platform" in configuration manager. Can just check if one is set to x64 and the other x86
check if you have specified the path correctly. for example I had written cpp instead of c++ and therefore suffered a lot and wasted like an hour searching here and there.
For Visual Studio 2019 users:
Project(P) > yours_project_name properties(P) > Platform Toolset Visual Studio 2019(V###)
Reasoning: You might download the project from Online and they used other version of Visual Studio as Platform.
Project(P) > yours_project_name properties(P) > Windows SDK Version ##.#(latest installed version).
Reasoning: You might download the project from Online and they used version SDK 8.0 while you have SDK 10.0

I am able to create Dlls and am able to access their header files by manually adding the file path of the .lib file to Project Properties -> VC++ Directories -> Library Directories as well as Proj Properties -> C/C++ -> Additional Include Directories. Everything works properly when I do this, BUT every time I open my project on a new machine I have to manually change all of these paths.
I tried setting them to relative paths instead (i.e. ..\ProjectName\Debug) but this did not work. Is there any way to include the necessary library files in my project so that the project will work automatically no matter which machine it is on?
Relative paths should be fine. It didn't work for you because you set incorrect paths I guess.
If .. confuses you and you are not sure what directory it refers to, you can use macros that are defined within Visual Studio IDE like $(SolutionDir) or $(ProjectDir). Note that these macros include / at the end so when you specify path by using them it looks like this: $(SolutionDir)dep/include.
Hope this helps.
I am using OF in my project and I want to use some add-ons but I have to add .cpp files to my project in order to compile them. I don't like it. Is there any option so I could specify a folder to scan for source files and compile every .cpp file it finds?
I thought it might be Source Directories in VC++ Directories section but it didn't work. Then I don't really get what it does.
If you want to compile sources using Visual Studio, you will have to add them to your project.
There is nothing wrong about adding external sources to your project in a nice filter.
You can also create a makefile to be used by Visual Studio which will list sources you need.
I'm not aware of an option that does what you ask for in VS. The Source directories configuration is used for locating source files that go along with libraries that you are using in your project. This way you can use the library in its binary format without the need to recompile it every time you rebuild your project, but you can also step into its code while debugging.
Is there a way to adjust visual-C++ (MS VS 2010 EE) project properties in such a way, that the same .sln files can be built just in one click among different computers (on Windows, of course)? - so it will be possibly to upload visual-C++ projects to SVN server. Project uses some libraries (header and .lib files) with absolute (system dependent) path (e.g. boost) and it's own utils.
You can use environment variables in your project settings by enclosing them in $(). e.g. if your environment defines BOOST_INCLUDE:
set BOOST_INCLUDE=C:\boost\include\boost-1_45
then you can use $(BOOST_INCLUDE) in your settings to refer to the Boost include directory.
Visual studio allows you to configure search directories for include files and libraries per system. You must agree with your colleages which folders should be made part of this scheme. Alternatively, you could use a set of predetermined environment variables and use paths relative to those.
Visual studio has some identifier like $(ProjectDir) that you can use in the project settings.
For example you could put a path like "$(ProjectDir)....\headers\boost\" in your include search path and it would work for multiple location of $(ProjectDir).
Other like $(ProjectName), $(ConfigurationName), $(IntDir) (Intermediate directory) can also be usefull.
I don't have a reference link for the moment.
