问题 I have a Visual Studio 2015 C++ project which I wanted to upgrade to VS 2017. I had already denied the automatic prompts to upgrade my project when I first opened my project in VS 2017 (wasn't sure I wanted to upgrade at the time) so I couldn't update my project that way. Instead, I just went to my project's: Properties->Configuration Properties->General And in there I updated the 'Platform Toolset' option to 'Visual Studio 2017 (v141)' and also changed the 'Window SDK Version' to 10.0.16299

问题 Here's the code below, VS said that on line 109 ( MoveTo(hdc, x, y); "MoveTo" is undefined . Can someone explain me what's wrong ? This is a win32api application. // Win32Project.cpp : Defines the entry point for the application. // #include "stdafx.h" #include "Win32Project4.h" #include <windows.h> #include <stdio.h> #include <string.h> #include <math.h> #include <stdlib.h> LRESULT CALLBACK ChildWndProc(HWND, UINT, WPARAM, LPARAM); LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM); int

问题 I have a Visual Studio solution that contains multiple C# projects and a C++ project. The C++ project is properly configured to build both for x64 and win32 (has separate output directories, proper binaries referred for 32 and 64 and so on) and default configuration is x64. C# projects are configured for Any CPU. How can I configure my solution to build the C++ project for both x64 and win32 when building the entire solution? P.S.: Batch build won't do the job for this case because I need to

问题 I'm doing some legacy work with Python 2.7.18 in 64 bit. When PIP calling the compiler (VC for Python), it erroneously refer to 32-bit (x86) sources looking for include files, for example "-IC:\Program Files (x86)\MySQL\MySQL Connector C 6.0.2\include" . For 32-bit everything works all OK; for 64-bit the pre-compiled wheel file is an alternative that I prefer not to use for now. I'm wondering did I miss any setting pointing python and its compiler to 64-bit instead of x86? Or, at lease I want

问题 Having installed VS 2019 on my PC, and opening up a new project, i get 408 errors that all say it cannot open various source .h files, such as errno.h, float.h, corecrt.h, etc. or 'the global scope has no "acosf" 'I had just installed visual studio and have no clue how it works, and have not done anything other than install it and open up a new project. Possibly useful information: It was not installed in the default location, but on the D: drive visual studio works fine when I open it with

问题 I'm working on a project that requires me to compile C++ code using MSVC, but I am working mostly with VSCode. As such, I was wondering if there is a way for me to add the Developer Powershell as an integrated terminal, so that I can compile without needing a secondary terminal open. I thought of just opening VSCode from the Developer PS itself, but since this is mostly a temporary project it seemed like a lot of repetitive work. I tried using the Shell launcher extension for VSCode but it
