Wmi error: Error getting next element: Unknown Error

[ahmad-kemsan]

Hi,

I tried creating a new class for CPU but got this error:

"Wmi error: Error getting next element: Unknown Error".

struct Win32_BaseBoard
{
        Win32_BaseBoard() :
            Product(),
            SerialNumber(),
            Manufacturer()
        { }
        void setProperties(const WmiResult& result, std::size_t index) {
            result.extract(index, "Product", (*this).Product);
            result.extract(index, "SerialNumber", (*this).SerialNumber);
            result.extract(index, "Manufacturer", (*this).Manufacturer);
        }
        static std::string getWmiClassName()
        {
            return "Win32_BaseBoard";
        }

        std::string Product;
        std::string SerialNumber;
        std::string Manufacturer;

};
