VS Code cannot open iostream - c++

Why is my VS Code giving the error of updating #include path and what does it mean? It writes that it cannot open iostream source file. I have successfully installed all extensions and included path too.

gtk/gtk.h: No such file or directory, on Windows, using VS code

I try to compile a cpp file with this header:
#include <stdlib.h>
#include <gtk/gtk.h>
I work with MSYS2, so both the compiler and the gtk library are installed through it. The cpp compiler path is:
D:\msys\usr\bin\cpp.exe
and here is the VS code include path additions, which I supplied to the IntelliSense Configurations page under "include path":
D:\msys\mingw64\include\gtk-2.0\**
D:\msys\mingw64\include\**
D:\msys\mingw64\lib\**
D:\msys\usr\include\**
and I have gtk etc. in the include folder. I actually installed three different versions of gtk, 2-4.
Before I added them to the include path, I got an error like "cannot open source file", and after adding them I get the
fatal error: gtk/gtk.h: No such file or directory
error. gtk/gtk.h is located just inside gtk-2.0. What am I doing wrong?
Thanks a lot.

C++ project is not finding its header files (visual studio)

I have not used C++ in visual studio in a lonnng lonnng time so probably this is a basic question but I would like some help.
I am opening someone else C++ code and the first thing I notice is that it is not recognizing its includes.
For example I have a main.cpp that has
#include "stdafx.h"
#include "myheader.h"
this cpp file is inside a "source" folder and those header files are under a "headers" folder.
I got an error "cannot open source file "stdafx.h" and "cannot open source file "myheader.h"
It is been ages I haven't touched C++ in visual studio. What configuration I should do to fix this?
if source and headers folders are in same level in folder structure you can use
#include "..\headers\myheader.h"
Similarly locate your stdafx.h and add the relative path to the .cpp file.

Include the tlhelp32 header file

I need to include the tlhelp32.h header file from the Tool Help Library but it always comes up with the following error:
error C1083: Cannot open include file: 'tlhelp32.h': No such file or
directory
I did a little bit of research and tried to first include the windows.h header file but this did not change anything.
I'm coding in C++ using Visual Studio 2013 Express with Windows 10 1709. Do I have to download anything else?

How to fix C++ header file location error for OpenCV on Mac OS X Sierra

I just finished the OpenCV installation on Mac OS X, but I'm continuously getting errors about my header files. For example, when I add #include <opencv2/core.hpp> I immediately get back "'opencv2/core.hpp' file not found".
I started modifying the script to include the relative path instead, #include "/Users/daniellebarnas/opencv-master/modules/core/include/opencv2/core.hpp" which removes the first error, but starts sending me down a rabbit hole of modifying every #include"HEADER FILE" within any relevant header files,
e.g.
/Users/daniellebarnas/opencv-master/modules/core/include/opencv2/core/neon_utils.hpp:45:10: 'opencv2/core/cvdef.h' file not found
/Users/daniellebarnas/opencv-master/modules/core/include/opencv2/core.hpp:54:10: In file included from /Users/daniellebarnas/opencv-master/modules/core/include/opencv2/core.hpp:54:
/Users/daniellebarnas/Desktop/Mote/C++/OpenCV Tracker/OpenCV Tracker/main.cpp:11:10: In file included from /Users/daniellebarnas/Desktop/Mote/C++/OpenCV Tracker/OpenCV Tracker/main.cpp:11:
So I have to then go into each subsequent file and change the paths.
How can I build the code just using the standard #include or #include"HEADER FILE" without changing the path statements in every .hpp?
I installed OpenCV through Homebrew in Terminal, and I'm wondering if maybe there was an error in the installation or if there's something I can modify after the fact to fix this...

OpenCV Include error "Cannot open source file"

I am new in OpenCV. I had install Visual Studio 2015 and OpenCV3.1.
I had included all the dependencieas and include file location.
But I am getting error:
cannot open source file"opencv2/imgproc/imgproc.hpp"
cannot open source file"opencv2/imgcodecs.hpp"
cannot open source file"opencv2/highgui/highgui.hpp"
Anyone can help whats is the problem?
In the additional Include directories the path should be something like .. 'C:\OpenCV-3.0.0\opencv\build\include' once whether it is
#include "opencv2/imgcodecs.hpp" or #include "opencv2/imgcodecs/imgcodecs.hpp" because in the version i am using header file inside the folder imgcodecs.
