idee détection cpu sous windoz

[thaeron]

Se baser sur le code d'xchat pour la détection de la version de windoz ainsi que du cpu :

/* code issu d'xchat pour avoir les infos sur le système 
exemples :
Windows 6.0 [i1586/1,90GHz]
Windows 5.1 [i1586/3,01GHz]
*/


#ifdef WIN32

	HKEY hKey;
	int result, data, dataSize;

		"CentralProcessor\\0", 0, KEY_QUERY_VALUE, &hKey) == ERROR_SUCCESS)
	{
		dataSize = sizeof (data);
		result = RegQueryValueEx (hKey, "~MHz", 0, 0, (LPBYTE)&data, &dataSize);
		RegCloseKey (hKey);
		if (result == ERROR_SUCCESS)
			return data;
	}
	return 0;	/* fails on Win9x */
}
