from c # I got the system serial number with the help of this code (not me)
public static string getSystemSerialNumber()
{
string mbInfo = string.Empty;
ManagementScope scope = new ManagementScope(@"\\" + Environment.MachineName + @"\root\cimv2");
scope.Connect();
ManagementObject wmiClass = new ManagementObject(scope, new ManagementPath("Win32_BaseBoard.Tag=\"Base Board\""), new ObjectGetOptions());
foreach (PropertyData propData in wmiClass.Properties)
{
if (propData.Name == "SerialNumber")
{
mbInfo = Convert.ToString(propData.Value);
break;
}
}
return mbInfo;
}
it returns the following string: /8ZBPX**/CN12966791****/ , I want to get exactly string above but using c++ (windows10). i found this code:
system("wmic bios get serialnumber > sn.txt");
wchar_t sn[16];
FILE* fp = fopen("sn.txt", "r, ccs=UTF-8");
fgetws(sn, 16, fp); //dummy read of first line
fgetws(sn, 16, fp); //now sn contains 2nd line
fclose(fp); //cleanup temp file
remove("sn.txt");
printf("The serial Number is: %ws\n", sn);
and it returns the following string: 8ZBPX**, I didn't know how to find the information chain behind.
How can i get full system serial number in c++? Many thanks!
The SO answer you referenced: C++ How do I pass a system serial number into a variable?
references some MSDN links, one of which directs you to Example: Getting WMI Data from the Local Computer.
This article is a good starting point for creating your conversion of the 'getSystemSerialNumber()' function from your question.
Taking the code from that article verbatim, you can change just a couple of lines to convert it to query for serial number (a few other comment lines and output lines should be changed as well for clarity/correctness).
You can then further modify the 'main()' function to return the value to mimic your C# function.
Here's the modified version:
#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;
// Step 1: --------------------------------------------------
// Initialize COM. ------------------------------------------
hres = CoInitializeEx(0, COINIT_MULTITHREADED);
if (FAILED(hres))
{
cout << "Failed to initialize COM library. Error code = 0x"
<< hex << hres << endl;
return 1; // Program has failed.
}
// Step 2: --------------------------------------------------
// Set general COM security levels --------------------------
hres = CoInitializeSecurity(
NULL,
-1, // COM authentication
NULL, // Authentication services
NULL, // Reserved
RPC_C_AUTHN_LEVEL_DEFAULT, // Default authentication
RPC_C_IMP_LEVEL_IMPERSONATE, // Default Impersonation
NULL, // Authentication info
EOAC_NONE, // Additional capabilities
NULL // Reserved
);
if (FAILED(hres))
{
cout << "Failed to initialize security. Error code = 0x"
<< hex << hres << endl;
CoUninitialize();
return 1; // Program has failed.
}
// Step 3: ---------------------------------------------------
// Obtain the initial locator to WMI -------------------------
IWbemLocator* pLoc = NULL;
hres = CoCreateInstance(
CLSID_WbemLocator,
0,
CLSCTX_INPROC_SERVER,
IID_IWbemLocator, (LPVOID*)&pLoc);
if (FAILED(hres))
{
cout << "Failed to create IWbemLocator object."
<< " Err code = 0x"
<< hex << hres << endl;
CoUninitialize();
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))
{
cout << "Could not connect. Error code = 0x"
<< hex << hres << endl;
pLoc->Release();
CoUninitialize();
return 1; // Program has failed.
}
cout << "Connected to ROOT\\CIMV2 WMI namespace" << endl;
// 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))
{
cout << "Could not set proxy blanket. Error code = 0x"
<< hex << hres << endl;
pSvc->Release();
pLoc->Release();
CoUninitialize();
return 1; // Program has failed.
}
// Step 6: --------------------------------------------------
// Use the IWbemServices pointer to make requests of WMI ----
// Query the system board
IEnumWbemClassObject* pEnumerator = NULL;
hres = pSvc->ExecQuery(
bstr_t("WQL"),
bstr_t("SELECT * FROM Win32_Baseboard WHERE Tag = \"Base Board\""),
WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,
NULL,
&pEnumerator);
if (FAILED(hres))
{
cout << "Query for system board serial number failed."
<< " Error code = 0x"
<< hex << hres << endl;
pSvc->Release();
pLoc->Release();
CoUninitialize();
return 1; // Program has failed.
}
// Step 7: -------------------------------------------------
// Get the data from the query in step 6 -------------------
IWbemClassObject* pclsObj = NULL;
ULONG uReturn = 0;
while (pEnumerator)
{
HRESULT hr = pEnumerator->Next(WBEM_INFINITE, 1,
&pclsObj, &uReturn);
if (0 == uReturn)
{
break;
}
VARIANT vtProp;
// Get the value of the Serial Number property
hr = pclsObj->Get(L"SerialNumber", 0, &vtProp, 0, 0);
wcout << " Serial Number : " << vtProp.bstrVal << endl;
VariantClear(&vtProp);
pclsObj->Release();
}
// Cleanup
// ========
pSvc->Release();
pLoc->Release();
pEnumerator->Release();
CoUninitialize();
return 0; // Program successfully completed.
}
The effective lines that were changed are as follows:
You'll see that the SELECT statement looks similar to your C# ManagementPath constructor call:
hres = pSvc->ExecQuery(
bstr_t("WQL"),
bstr_t("SELECT * FROM Win32_Baseboard WHERE Tag = \"Base Board\""),
WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,
NULL,
&pEnumerator);
Query for the correct property:
hr = pclsObj->Get(L"SerialNumber", 0, &vtProp, 0, 0);
I didn't tidy this up intentionally (there are so many opportunities, e.g., using namespace std; needs to go, smart pointers should be used throughout, etc.), but left it intact so that you can compare to the original MSDN code.
