我想学习如何使用c ++从本地机器的BIOS中获取资产标签和序列号。我现在已经在网上搜索了将近一个小时,到目前为止,我想出的是用vb编写的一些脚本。
我正在使用Windows 7计算机,但也希望它能与Windows 8一起使用。

您可以使用WMI
示例函数将类似于以下源代码,我将它放在一起以获取PC的序列号,它似乎工作得非常好。从Windows注册表中删除一个序列号然后忽略它,因为它适用于专门的环境。
# pragma comment(lib, "wbemuuid.lib")
static SHORT CDeviceConfigCheckSerialNumber (TCHAR *tcsSerialNo)
{
HRESULT hres;
IWbemLocator *pLoc = NULL;
*tcsSerialNo = 0; // initialze return string to empty string
hres = CoCreateInstance(
CLSID_WbemLocator,
0,
CLSCTX_INPROC_SERVER,
IID_IWbemLocator, (LPVOID *) &pLoc);
if (FAILED(hres))
{
return 1; // Program has failed.
}
// Step 4: -----------------------------------------------------
// Connect to WMI through the IWbemLocator::ConnectServer method
IWbemServices *pSvc = NULL;
// Connect to the root\cimv2 namespace with
// the current user and obtain pointer pSvc
// to make IWbemServices calls.
hres = pLoc->ConnectServer(
_bstr_t(L"ROOT\\CIMV2"), // Object path of WMI namespace
NULL, // User name. NULL = current user
NULL, // User password. NULL = current
0, // Locale. NULL indicates current
NULL, // Security flags.
0, // Authority (for example, Kerberos)
0, // Context object
&pSvc // pointer to IWbemServices proxy
);
if (FAILED(hres))
{
pLoc->Release();
return 2; // Program has failed.
}
// Step 5: --------------------------------------------------
// Set security levels on the proxy -------------------------
hres = CoSetProxyBlanket(
pSvc, // Indicates the proxy to set
RPC_C_AUTHN_WINNT, // RPC_C_AUTHN_xxx
RPC_C_AUTHZ_NONE, // RPC_C_AUTHZ_xxx
NULL, // Server principal name
RPC_C_AUTHN_LEVEL_CALL, // RPC_C_AUTHN_LEVEL_xxx
RPC_C_IMP_LEVEL_IMPERSONATE, // RPC_C_IMP_LEVEL_xxx
NULL, // client identity
EOAC_NONE // proxy capabilities
);
if (FAILED(hres))
{
pSvc->Release();
pLoc->Release();
return 3; // Program has failed.
}
// Step 6: --------------------------------------------------
// Use the IWbemServices pointer to make requests of WMI ----
// For example, get the name of the operating system
IEnumWbemClassObject* pEnumerator = NULL;
hres = pSvc->ExecQuery(
bstr_t("WQL"),
// bstr_t("SELECT * FROM Win32_SystemEnclosure"),
// bstr_t("SELECT * FROM Win32_BaseBoard"),
bstr_t("SELECT * FROM Win32_BIOS"),
WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,
NULL,
&pEnumerator);
if (FAILED(hres))
{
pSvc->Release();
pLoc->Release();
return 4; // Program has failed.
}
// Step 7: -------------------------------------------------
// Get the data from the query in step 6 -------------------
IWbemClassObject *pclsObj;
ULONG uReturn = 0;
SHORT sRetStatus = -100;
while (pEnumerator)
{
HRESULT hr = pEnumerator->Next(WBEM_INFINITE, 1, &pclsObj, &uReturn);
if(0 == uReturn)
{
break;
}
VARIANT vtProp;
// Get the value of the Name property
hr = pclsObj->Get(L"SerialNumber", 0, &vtProp, 0, 0);
if (!FAILED(hres)) {
switch (vtProp.vt) {
case VT_BSTR:
_tcscpy (tcsSerialNo, vtProp.bstrVal);
sRetStatus = 0;
break;
}
}
VariantClear(&vtProp);
pclsObj->Release();
}
pEnumerator->Release();
// Cleanup
// ========
pSvc->Release();
pLoc->Release();
// if the search for a serial number in the BIOS did not provide
// something then lets see if the NCR Retail Systems Manager has
// put a serial number into the Windows Registry.
if (sRetStatus != 0) {
ULONG ulCount = 0;
TCHAR lpszValue[256] = {0};
ScfGetRsmValue (L"SerialNumber", &ulCount, lpszValue);
if (ulCount > 0) {
_tcscpy (tcsSerialNo, lpszValue);
sRetStatus = 0;
}
}
return sRetStatus;
