How can I open a url in a c++ program

I tried opening a url in my program but I keep getting errors from "shellapi.h", how can I fix it?

ShellExecuteA(NULL, NULL , "chrome.exe", this->photo.c_str(), NULL, SW_SHOWMAXIMIZED);

For a cross-platform solution, you can set this header:

#ifdef _WIN32
static int platform = 1;
#elif _WIN64
static int platform= 1;
#elif __linux__
static int platform = 2;
#elif __APPLE__
static int platform = 3;
#else
static int platform = 0;
#endif

and then create a method to open the URL, with the code below:

std::string str;
switch(platform) {
    case 1:
       str = "explorer";
       break;
    case 2:
        str = "xdg-open";
        break;
    case 3:
        str = "open";
        break;
    default:
        std::cout << "Should never happen on the 3 defined platforms" << std::endl;
}
str.append(" " + url);
std::system(str.data());

Remember to provide a URL string, in this case a const std::string& url.

Probably better to just use the default browser, like this:

// assumes photo.c_str() is valid URL ...
ShellExecuteA(0, NULL, photo.c_str(), NULL, NULL, SW_SHOWDEFAULT);

There are a number of c++ library available for this, and here you can find something.
