Visual Studio C++ 不能在同一解决方案或外部文件夹中包含其他目录

Question

So I'm learning C++ this semester and right on the first laboratory I got a problem which nor me, nor my prof could solve. Our task was really basic. Create a solution, create a project in which create a function and a header file. In the header file is the declaration of the function. Then create a new project (in same solution), add the old one as a reference. Now comes the part which gave me a headache. Add the path of the folder of the.h file into the " Additional Include Directories " section. Well I do that and nothing. I tried diferent locations, but nothing worked. Any idea how can I solve this problem?

Here are some pictures:

The "code". It is not much

The path

Answer 1

Even if the directory is listed, you still have to reference header with #include "yourHeader.h" wherever you want to use the forward-declared functions.

Answer 2

I suggest that you could first manually find the directory where the.h file is located, and then add the path in VS.

If it doesn't work, I suggest that you could add the path in Properties->VC++ Directories->Include Directories .

Also, you could refer to Microsoft Docs for more information.

Answer 3

I reinstalled VisualStudio and now it works prefctly. FML
