如何在vc ++中检索bios序列号 [英] how to retrive bios serial number in vc++
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

如果（FAILED（hres））
{
cout<< ; 无法初始化安全性。错误代码= 0x

CoUninitialize（）;

}
//第3步：-------------- -------------------------------------
//获得最初的WMI的定位器-------------------------

//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。

推荐答案
可能没有bios序列号。转到命令提示符并运行此命令
May not have a bios serial number. Go to command prompt and run this command
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：
http：// msdn .microsoft.com / zh-CN / library / aa390423（v = vs.85）.aspx [ ^ ]
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;
