NX二次开发-获取当前dll的项目路径、获取配置文件路径

1. 获取当前dll的项目路径；

string NXCommon::GetUserDir()
{
    std::string dll = GetHostName();
    string dir, fname;
    SplitFileName(dll, dir, fname);

    string mdlName = GetModuleFullPath(fname);
    string tailName = "application\" + fname;

    string userDir = mdlName.substr(0, mdlName.size() - tailName.size());

    return userDir;
}

string GetHostName()
    {
        HMODULE handle = NULL;

        bool isOK = GetModuleHandleExA(GET_MODULE_HANDLE_EX_FLAG_FROM_ADDRESS,
            (char*)_ReturnAddress(), &handle);

        if (isOK)
        {
            char name[1024] = { 0 };
            GetModuleFileNameA(handle, name, 1024);

            return std::string(name);
        }
        else
        {
            return "";
        }
    }

std::string GetModuleFullPath(std::string dllName)
    {
        HMODULE handle = GetModuleHandleA(dllName.c_str());

        char lpFileName[_MAX_PATH + 1] = { '/0' };
        GetModuleFileNameA(handle, lpFileName, _MAX_PATH);

        return std::string(lpFileName);
    }

2. 获取配置文件路径。

string NXCommon::GetConfigDir()
{
    return GetUserDir() + "config\";
}
