无法在 visual studio 2022 上打开源文件

Question

#define _WINSOCK_DEPRECATED_NO_WARNINGS
#define _CRT_SECURE_NO_WARNINGS

#pragma comment(lib, "ws2_32.lib")

#include <Winsock2.h>
#include <stdio.h>
#include <stdlib.h>
#include <Windows.h>

I have visual studio 2022 installed and I just downloaded the newest SDK. I am trying to use winsock (I am using parallels in m1 mac and running windows 10) and none of the libraries are working. STDIO.H is pulling up "cannot open source file".. for all headers.

Answer 1

Please check if the header file is included in the header file directory. the C++ headers path are:

1.C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.15.26726\include

2.C:\Program Files (x86)\Windows Kits\10\Include\10.0.17134.0\ucrt

The first contains standard C++ headers such as iostream . The second contains legacy C headers such as stdio.h .

If you are going to use C++ to develop desktop applications, I recommend you to refer to my setup.

Regarding the problem that the library cannot be used, I suggest you to read this document carefully, which explains how to use the dll. If this solution does not solve your problem, please leave a message.

Answer 2

stdio and stdlib are part of the C++ Standard Library headers, if you are getting the error E1696: 'cannot open source file , you might have to retarget the solution/project. Do the following:

1. Right-click the Solution in the Solution Explorer pane;
2. Retarget solution;
3. Follow the steps/press OK.

Hope it helps.
