c++ - I can not open and image using the SFML library

Question

I am having trouble opening the test15.bmp. When I run the program it tries to open a window but crashes. The problem line as much as I could understand is image.loadFromFile(...);

Exception thrown at 0x50E82CC4 (vcruntime140.dll) in
MandelbrotProject.exe: 0xC0000005: Access violation reading location
0x00741000.

This is the exception I get when I use image.loadFromFile("test15.bmp") instead of the absolute path.

I have linked and included everything as it was described in the SFML tutorials. https://www.sfml-dev.org/tutorials/2.5/start-vc.php

I am using Visual C++(2017)-32 bit SFML and Microsoft Visual Studio 2017.

#include "pch.h"
#include<iostream>
#include "Fractal.h"
#include "RGB.h"
#include "Zoom.h"

using namespace project;

int main() {

    Fractal fractal(800, 600);

    fractal.addRange(0.0, RGB(0, 0, 0));
    fractal.addRange(0.3, RGB(255, 0, 0));
    fractal.addRange(0.5, RGB(255, 255, 0));
    fractal.addRange(1.0, RGB(255, 255, 255));
    fractal.addZoom(Zoom(295, 202, 0.1));
    fractal.addZoom(Zoom(312, 304, 0.1));//specified zooms
    fractal.run("test15.bmp");

    cout << "Zooming!" << endl;
    double zoom = 0.1;
    double offsetX = 400.0;
    double offsetY = 300.0;

    sf::RenderWindow window(sf::VideoMode(800, 600), "Mandelbrot");
    window.setFramerateLimit(0);
    sf::Image image;
    image.loadFromFile("D:Visual Studio

By default, Visual Studio consider project directory the working directory.

If I'm not wrong, D:Visual Studio projectsMandelbrotProjectMandelbrotProject in your case. You should ensure your test15.bmp is inside that directory.

Just in case, you can check which one is your $(ProjectDir) by opening Project Properties->Configuration Properties->Output Directory (any field can be used). Click on the drop-down arrow and Edit. Open Macros and write $(ProjectDir)
