c++ - GetVersionEx bajo Windows 8

winapi windows-8

Question

Estoy escribiendo un código C ++ para determinar en qué sistema operativo se está ejecutando. GetVersionEx() API GetVersionEx() para hacer eso, y este código como tutorial, pero no parece manejar Windows 8. ¿Alguien sabe cómo arreglarlo para que se ejecute en Windows 8?

Answer 1

De acuerdo con esta página de MSDN , se recomienda utilizar las funciones de Version Helper en lugar de GetVersionInfoEx para determinar la versión de Windows en ejecución. Como se describe en la página GetVersionEx , esa API puede desaparecer en el futuro.

Answer 2

Ok, esperaba que alguien ya lo hubiera hecho ... pero, supongo que no, así que aquí tienes:

Vista previa del consumidor de Windows 8

//OSVERSIONINFO for GetVersionEx returns:
dwMajorVersion = 6;
dwMinorVersion = 2;
wProductType = 1;

//GetProductInfo returns:
dwType = 0x4A;   //Not documented yet???

PD. No tengo instalado VS IDE allí. Tuve que hacer una pequeña aplicación para conseguir esos ...

Answer 4

Otro método posible para la validación básica (mayor, menor) del sistema, pero no los detalles del producto en profundidad, es verificar la versión de un archivo del sistema central, por ejemplo kernel32.dll.
