VC++如何获取机器码?硬盘序列号、CPU编号、BIOS编号等~

Posted 2023-02-21

我知道那个用GetVolumeInformation得到的不是硬盘的序列号，这个大家可以去百度一下。得到的结果是分区的编号，这个东西是可以用软件刷洗更改的！ 那么到底该用什么函数来获取，我找了半天没有找到，举个例子最好！麻烦大家了~~

参考技术A 可以试试使用WMI（在msdn上有详细的信息）:
硬盘序列号:
用Win32_PhysicalMedia
class.
CPU编号:
用Win32_Processor
class.
Bios编号:
用Win32_BIOS
class.
下面例子取得硬盘的序列号，其他的用法也类似(msdn上的例子，把Win32_OperatingSystem改成了Win32_PhysicalMedia）:
#define
_WIN32_DCOM
#include
<iostream>
using
namespace
std;
#include
<comdef.h>
#include
<Wbemidl.h>
#
pragma
comment(lib,
"wbemuuid.lib")
int
main(int
argc,
char
**argv)

HRESULT
hres;

1:

hres

(FAILED(hres))

Step
2:
--------------------------------------------------
//
Set

--------------------------
//
Note:
If
