I want to open a video file in my OpenCV C++ application with
cap.open("../../data/Example.MP4");
but somehow when I run the application in Visual Studio 2015 (I've tried both Debug & Release mode), it cannot find the file.
Surprisingly if I run the application by just double clicking the .exe in Windows Explorer, everything works fine and the video file opens as desired.
Does somebody know why Visual Studio cannot find the file?
Thanks a lot!
The problem is related to the Project's Working directory, on Visual Studio. From inside it, it isn't finding the file...
Go to Project Properties, Debugging. There you will see, by default, that the Working directory is your project directory. Change it to $(OutDir) and your path should be fixed.

I have copied a C++ solution folder written with visual studio 2013 to my Pc and tried to run it (I mean VS Debugging) with VS 2022. the solution Contains 5 projects but I just target one of them so unloaded the rest and set the one as Startup project and this error happened.
Error Image
Solution file is working well on first pc and project is not a win32 project its x64 (I don't know much from win32 or x64).
Unable to start program. [VALUE].dll is not a valid Win32 application error in Visual Studio 2017
According to this question I tried selecting project, setting as startup, repairing VS, installing vcredist_x64 but non helped.
After Running, VS make Debug folder in solution Directory not the project "LP_Dll\x64\Debug" (LP_Dll is the solution name) without any .exe file, and the error path is exactly this folder, can it be from that?
Project properties the "Configuration Type" was mistakenly changed to .dll.
I have a problem that will be very simple to solve but I don't know how to do it.
Scenario: I want to run an emulator coded in C++ by a YT (javidx9) in Visual Studio. The project is here: https://github.com/OneLoneCoder/olcNES and the folder is "Part#2 - CPU"
Problem: I never use Visual Studio, so its something new for me, and my problem is that I don't know how to run the project (emulator). And I can't find any post or article on the internet about my problem. (I tried to create an empty project in VS and then copy the emulator files to the folder of my empty project and then run it, but it sent me an error that the files were not found (and its because that isn't the correct way to run the program and I don't know how to do it)).
My request: I would be very grateful if someone could explain to me how to open and run this project (the emulator) correctly in Visual Studio.
Thanks!!!
Your project does not have. sln file. You need to create new project in visual studio. Last file has main function as below. You need to run this main file(olcNes_Video1_6502.cpp)
You may need to check path of headers included from other projects.
Just installed visual studio 2019 on windows 10, was using visual studio for the first time and ran into the following error, It's a basic hello world console program that I tried to run.
error C1083: Cannot open include file: 'corecrt.h': No such file or directory
1>Done building project "ConsoleApplication2.vcxproj" -- FAILED.
Severity Code Description Project File Line Suppression State
Warning MSB8003 The WindowsSDKDir property is not defined. Some build tools may not be found. ConsoleApplication2 C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Microsoft\VC\v160\Microsoft.CppBuild.targets 434
I tried searching for this error over YouTube and of course here, and also Microsoft's offical forum but couldn't find anything.
#include <iostream>
using namespace std;
int main()
{
cout << "Hello World!\n";
}
the code looks just fine.
I ran into the same issue today. It turns out I didn't check the Win10SDK to save disk space while installation.
Solution:
In VS, go Tools menu=>Get Tools and Features=>install the Windows 10 SDK(10.XX.XX.XX)
Once installed, launch VS and open your project, right-click your project(NOT Solution)->properties->General->Windows SDK Version, check the value should be 10.0 instead of blank.
Then the compiling just worked.
I've got the same issue and turned out that I haven't installed Windows SDK. It can be done by typing "Install Windows SDK" into visual studio's search prompt
I had same problem when I installed Visual Studio 2019 on Windows7 and opened project created in Visual Studio 2017 (witch wasn't installed on that machine).
To solve the problem I went to project Properties -> General -> Windows SDK Version
And changed it from 10 to 8.1.
I fixed this issue by repairing Windows SDK. Now it's working as expected.
Steps:
Go to Settings>Apps & Features.
Click on Windows Software Development Kit - Windows 10.0.18362.1
(Note: Version number might be different for you)
Click on Modify.
Select Repair from options.
Click Next.
Restart VS and try running your project.
I was just having thesame issue so I figured maybe the headers were in a different directory than where the program is searching. When I went looking for tge header files none existed. So the problem is probably with iostream not existing.
So for a class we have a couple of programs where we are using opengl. To make setup easier we started by cloning glitter https://github.com/Polytonic/Glitter. I then compliled it according to the instructions for visual studio 2017 and added my code to the project I am working on. I did this on my desktop computer but saved the files in onedrive. When I open the same project on my laptop and try to build the project I get the error "the source directory D:/OneDrive/fall_2017/Glitter does not appear to contain CMakeLists.txt" and several other similar errors. On my laptop the directory to the files is C:/Users/Me/OneDrive/fall_2017/Glitter. The visual studio program lists the full path as D:/OneDrive/fall_2017/Glitter which is the path of the folder on my desktop.
Is there a way for me to change the filepath or is the issue with my cmake file? Do I have to rebuild it for every computer I use it on? I don't know a whole lot about visual studio so I don't know what I need to change to get this to work.
Turns out I have to rebuild on every computer. Thanks to those who left comments.
I am very desperate now...
I have project in Visual C++ 2010 using Qt and OpenCV. I got to phase I need to load XML file using openCV. But, I have no idea where is the working directory of my project, when run thru VS (F5). I mean, I read all config, copied desired file almost everywhere in my project folders, but it still is not seen by my EXE (OpenCV)...
What Am I doing wrong? Thanks.
right click on your project click on properties/Configuration Properties/debugging you start in whatever working directory is set to.
