问题描述

您好我在vc ++中收集bios信息。我检索它的版本。我该如何收集有关bios序列号的信息。直到没有我处理这段代码。



// bios info.cpp:定义控制台应用程序的入口点。

//



#includestdafx.h



#define _WIN32_DCOM

#include< iostream>

使用命名空间std;

#include< comdef.h>

#include< wbemidl.h>



#pragma comment(lib,wbemuuid.lib)



int main(int argc, char ** argv)

{

HRESULT hres;



//第1步:---- ----------------------------------------------

//初始化COM。 ------------------------------------------



hres = CoInitializeEx(0,COINIT_MULTITHREADED);

if(FAILED(hres))

{

cout<< 无法初始化COM库。错误代码= 0x

<< hex<< hres<< endl;

返回1; //程序失败了。

}



//第2步:-------------- ------------------------------------

//设置一般的COM安全性等级--------------------------



hres = CoInitializeSecurity(

NULL,

-1,// COM身份验证

NULL,//身份验证服务

NULL,//保留

RPC_C_AUTHN_LEVEL_DEFAULT,//默认验证

RPC_C_IMP_LEVEL_IMPERSONATE,//默认模拟

NULL,//验证信息

EOAC_NONE ,//附加功能

NULL //保留

);





如果(FAILED(hres))

{

cout<< ; 无法初始化安全性。错误代码= 0x

<< hex<< hres<< endl;

CoUninitialize();

返回1; //程序失败了。

}



//第3步:-------------- -------------------------------------

//获得最初的WMI的定位器-------------------------



IWbemLocator * pLoc = NULL;



hres = CoCreateInstance(

CLSID_WbemLocator,

0,

CLSCTX_INPROC_SERVER,

IID_IWbemLocator,(LPVOID *)& pLoc);



if(FAILED(hres))

{

cout<< 无法创建IWbemLocator对象。

<< 错误代码= 0x

<< hex<< hres<< endl;

CoUninitialize();

返回1; //程序失败。

}



//第4步:-------------- ---------------------------------------

//连接通过IWbemLocator :: ConnectServer方法获取WMI



IWbemServices * pSvc = NULL;



//连接使用

//当前用户获取root \ cimv2命名空间并获取指针pSvc

//以进行IWbemServices调用。

hres = pLoc-> ConnectServer(

_bstr_t(LROOT\\CIMV2),// WMI命名空间的对象路径

NULL,//用户名.NULL =当前用户

NULL,//用户密码.NULL =当前

0,// Locale。NULL表示当前

NULL,//安全标志。

0,//权限(例如,Kerberos)

0, //上下文对象

& pSvc //指向IWbemServices代理的指针

);



if(FAILED (hres))

{

cout<< 无法连接。错误代码= 0x

<< hex<< hres<< endl;

pLoc-> Release();

CoUninitialize();

返回1; //程序失败。

}



cout<< 已连接到ROOT \\CIMV2 WMI名称空间<< endl;





//第5步:------------------- -------------------------------

//在代理上设置安全级别--- ----------------------



hres = CoSetProxyBlanket(

pSvc,//表示要设置的代理

RPC_C_AUTHN_WINNT,// RPC_C_AUTHN_xxx

RPC_C_AUTHZ_NONE,// RPC_C_AUTHZ_xxx

NULL,//服务器主体名称

RPC_C_AUTHN_LEVEL_CALL,// RPC_C_AUTHN_LEVEL_xxx

RPC_C_IMP_LEVEL_IMPERSONATE,// RPC_C_IMP_LEVEL_xxx

NULL,//客户身份

EOAC_NONE / /代理功能

);



if(FAILED(hres))

{

cout<< 无法设置

<< hex<< hres<< endl;

pSvc-> Release();

pLoc-> Release();

CoUninitialize();

返回1; //程序失败了。

}



//第6步:-------------- ------------------------------------

//使用IWbemServices指针发出WMI请求----



//例如,获取操作系统的名称

IEnumWbemClassObject * pEnumerator = NULL ;

hres = pSvc-> ExecQuery(

bstr_t(WQL),

bstr_t(SELECT * FROM Win32_BIOS),

WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,

NULL,

& pEnumerator);



if(FAILED(hres))

{

cout<< 查询BIOS失败。

<< 错误代码= 0x

<< hex<< hres<< endl;

pSvc-> Release();

pLoc-> Release();

CoUninitialize();

返回1; //程序失败了。

}



//第7步:-------------- -----------------------------------

//从中获取数据在步骤6中查询-------------------



IWbemClassObject * pclsObj;

ULONG uReturn = 0;



while(pEnumerator)

{

HRESULT hr = pEnumerator->下一步(WBEM_INFINITE,1,

& pclsObj,& uReturn);



if(0 == uReturn)

{

休息;

}



VARIANT vtProp;





//获取Name属性的值

hr = pclsObj-> Get(LName,0,& ; vtProp,0,0);

wcout<< BIOS:<< vtProp.bstrVal<< endl;









VariantClear(& vtProp);



pclsObj->释放();

}



//清理

// ========



pSvc->发布();

pLoc-> Release();

pEnumerator-> Release();

if(!pclsObj)pclsObj-> Release();

CoUninitialize();

系统(暂停);

返回0; //程序已成功完成。

hi i am collecting bios information in vc++.i retrieve its version. how should i collect information on bios serial number. till no i work on this code.

// bios info.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"

#define _WIN32_DCOM
#include <iostream>
using namespace std;
#include <comdef.h>

if (FAILED(hres))
{
cout << "Failed to initialize COM library. Error code = 0x"
<< hex << hres << endl;

}

// Step 2: --------------------------------------------------
// Set general COM security levels --------------------------

if (FAILED(hres))
{

// the current user and obtain pointer pSvc
// to make IWbemServices calls.

推荐答案

wmic bios get serialnumber





这将显示序列号(如果有)。



现在从这里对示例代码进行这些更改:



[]





This will display the serial number if there is one.

Now make these changes to example code from here:

http://msdn.microsoft.com/en-us/library/aa390423(v=vs.85).aspx[^]

hres = pSvc->ExecQuery(
    bstr_t("WQL"),
    bstr_t("SELECT * FROM Win32_Bios"),
    WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,
    NULL,
    &pEnumerator);










// Get the value of the Serial Number property
hr = pclsObj->Get(L"SerialNumber", 0, &vtProp, 0, 0);
wcout << " Bios Serial Number : " << vtProp.bstrVal << endl;
