I am doing WinApi C programming with my colleague. We are using the visual studio. While I was loading the image, there was an error like the one in the picture below.

While debugging, I found out that this is an error caused by the lack of files on the path. You can simply add a file to the path to resolve the error, but you want to import the image from another specified path. The reason why you don't choose a simple method is that even though your colleagues use the same code, they succeed in importing files from different paths, so they don't get errors.

The path where I import the file is 'D:\BreakTogether\OutPut\bin\Res', and the path where my colleague imports the file is 'D:\BreakTogether\bin\Res'. Below is the code used to get the file path.

#include "pch.h"
#include "ResMgr.h"
#include "PathMgr.h"
#include "Image.h"

ResMgr::ResMgr()
{
}

ResMgr::~ResMgr()
{
    /*map<wstring, Image*>::iterator iter;
    for (iter = m_mapImg.begin(); iter != m_mapImg.end();   iter)
    {
        delete iter->second;
    }*/
    Safe_Delete_Map(m_mapImg);
}

Image* ResMgr::ImgLoad(const wstring& _strKey, const wstring& _strRelativePath)
{
    Image* pImg = ImgFind(_strKey);
    if (nullptr != pImg)
    {
        return pImg;
    }
    wstring strFilePath = PathMgr::GetInst()->GetRsrcPath();
    strFilePath  = _strRelativePath;
    pImg = new Image;
    pImg->Load(strFilePath);
    pImg->SetKey(_strKey);
    pImg->SetRelativePath(_strRelativePath);
    m_mapImg.insert(make_pair(_strKey, pImg));
    //  m_mapImg.insert({ _strKey , pImg });
    return pImg;
}

Image* ResMgr::ImgFind(const wstring& _strKey)
{
    auto iter = m_mapImg.find(_strKey);
    if (iter == m_mapImg.end())
    {
        return nullptr;
    }
    return static_cast<Image*>(iter->second);
}

#include "pch.h"
#include "PathMgr.h"
#include "Core.h"

PathMgr::PathMgr()
    : m_szRsrcPath{}
{
}

PathMgr::~PathMgr()
{
}

void PathMgr::Init()
{
    GetCurrentDirectory(255, m_szRsrcPath);

    int Length = wcslen(m_szRsrcPath);

    for (int i = Length - 1; i >= 0; i--)
    {
        if (m_szRsrcPath[i] == '\\')
        {
            m_szRsrcPath[i] = '\0';
            break;
        }
    }

    wcscat_s(m_szRsrcPath, 255, L"\\bin\\Res\\");

    SetWindowText(Core::GetInst()->GetWndHandle(), m_szRsrcPath);
}

I tried adding an image to the path where I load the file. That will solve the problem. However, it is inefficient because my colleague and I have to add the same file twice because we have different paths to load the image.

CodePudding user response：

If you can load the file normally when the image file is in place, there is no problem with your code. Go to your Project Property Pages -> Debugging -> Working Directory and align your path with your colleagues. If the problem is not solved, plz tell me more about your problem. Have a nice day!
