Finding how many PCI slots are on system

Hi guys, I'm trying to create code to determine how many PCI slots are currently on a system...available and used.

I have been trying to use the Win32_SystemSlot WMI class but it doesnt seem to be working properly.

Code:

---

//query systemslot
IEnumWbemClassObject* pEnumerator = NULL;
    hres = pSvc->ExecQuery(
        bstr_t("WQL"),
        bstr_t("SELECT * FROM Win32_SystemSlot"),
        WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,
        NULL,
        &pEnumerator);
//get class object
        IWbemClassObject *pclsObj;
    ULONG uReturn = 0;
            int noPCI = 0;
                int noAGP = 0;
                int noPCMIA = 0;
//loop through system slots
    while (pEnumerator)
    {
        //next object
        HRESULT hr = pEnumerator->Next(WBEM_INFINITE, 1,
            &pclsObj, &uReturn);
               
        VARIANT vtProp;
                //get connecter type data (unsigned int16 array)
                hr = pclsObj->Get(L"ConnectorType", 0, &vtProp, 0, 0);
               
                //create uint16 array to store data
                unsigned short aShort[sizeof(vtProp)];
                memcpy (aShort, (char*)(&vtProp), sizeof(aShort));
                for(int i=0; i<sizeof(aShort); i++)
                cout << aShort[i] << endl;

        VariantClear(&vtProp);

---

instead of outputting useful shorts containing data according to this table http://msdn.microsoft.com/en-us/libr...8VS.85%29.aspx (scroll down to connector type) it gives me instead the output:

8195 | -13364 | -13364 | -13364 | -5808 | 22 | -13364 | -13364 |
8195 | -13364 | -13364 | -13364 | -5808 | 22 | -13364 | -13364 |
8195 | -13364 | -13364 | -13364 | -5808 | 22 | -13364 | -13364 |

Which is the output for each iteration through the three system slots it loops through.

PCI slots should come up as 99. Any idea what i'm doing wrong?

You access a variant array using the safe-array COM API.

Use "SAFEARRAY *psa = V_ARRAY(&vProp);" to get the handle to the safe-array.
