create file from resource.rc return null

Question

i can't understand why findresource return null. i add new resources and import driver.sys.looked at all possible materials for studying this error, but found nothing to solve it. in all of the cases, zero is returned, what can i do wrong?

MAIN.CPP:

using namespace std;

#pragma warning(disable: 6387)

class Resource 
{
public:
    struct Parameters 
    {
        std::size_t size_bytes = 0;
        void* ptr = nullptr;
    };

private:
    HRSRC hResource = nullptr;
    HGLOBAL hMemory = nullptr;

    Parameters p;

public:
    Resource(int resource_id, const std::string& resource_class) {
        hResource = FindResource(nullptr, MAKEINTRESOURCEA(resource_id), resource_class.c_str());
        hMemory = LoadResource(nullptr, hResource);

        p.size_bytes = SizeofResource(nullptr, hResource);
        p.ptr = LockResource(hMemory);
    }

    auto GetResourceString() const 
    {
        std::string_view dst;
        if (p.ptr != nullptr)
            dst = std::string_view(reinterpret_cast<char*>(p.ptr), p.size_bytes);
        return dst;
    }
};

void GetFile() {
    Resource very_important(IDR_DRIVER1, "BINARY");
    auto dst = very_important.GetResourceString();
}

int main()
{
    Resource res(IDR_DRIVER1, "BINARY");

    system("pause");
    return 0;
}

IMG folder "driver.sys"/"DRIVER"

Answer 1

You are defining a resource whose ID is 101 and type is DRIVER :

#define IDR_DRIVER1                     101

IDR_DRIVER1             DRIVER                  "driver.sys"

But, you are then asking FindResource() to find a resource whose ID is 101 and type is BINARY rather than DRIVER :

Resource very_important(IDR_DRIVER1, "BINARY");
Resource res(IDR_DRIVER1, "BINARY");

You need to change that to this:

Resource very_important(IDR_DRIVER1, "DRIVER");
Resource res(IDR_DRIVER1, "DRIVER");
