Can you provide more details of the code or code snap ?
How can we guess where the errors occures and why? Confused | :confused:

I want to know how to find the HDD Serial Number from using C++ or C or any assembly code.

Thanks,
Anwar.

Check GetVolumeInformation() API where you get the information of the volume serial number in lpVolumeSerialNumber parameter.

Here you get more information[^]

If you need volume's serial number (for logical disks C:, D:, etc.), you can use GetVolumeInformation function.

If you need serial numbers of your hard disks as physical devices, you can follow the famous Windows Management Instrumentation (WMI) way, which does not look so simple:

#define _WIN32_WINNT 0x0400
#include <objbase.h>
#include <comdef.h>
#include <Wbemidl.h>

# pragma comment(lib, "wbemuuid.lib")

_COM_SMARTPTR_TYPEDEF(IWbemLocator, __uuidof(IWbemLocator));
_COM_SMARTPTR_TYPEDEF(IWbemServices, __uuidof(IWbemServices));
_COM_SMARTPTR_TYPEDEF(IEnumWbemClassObject, __uuidof(IEnumWbemClassObject));
_COM_SMARTPTR_TYPEDEF(IWbemClassObject, __uuidof(IWbemClassObject));


int main()
{

    CoInitializeEx(NULL, COINIT_MULTITHREADED);
    CoInitializeSecurity(
        NULL,
        -1,
        NULL,
        NULL,
        RPC_C_AUTHN_LEVEL_DEFAULT,
        RPC_C_IMP_LEVEL_IMPERSONATE,
        NULL,
        EOAC_NONE,
        NULL);

    IWbemLocatorPtr locator;

    CoCreateInstance(
        CLSID_WbemLocator,             
        0, 
        CLSCTX_INPROC_SERVER, 
        IID_IWbemLocator, 
        (LPVOID *)&locator
        );

    IWbemServicesPtr services;

    locator->ConnectServer(
        _bstr_t(L"ROOT\\CIMV2"),
        NULL,
        NULL,
        0,
        NULL,
        0,
        0,
        &services
        );


    IEnumWbemClassObjectPtr enumerator;
    services->ExecQuery(
        bstr_t("WQL"), 
        bstr_t("SELECT * FROM Win32_DiskDrive"),
        WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY, 
        NULL,
        &enumerator);

    IWbemClassObjectPtr object = 000;

    for( ; ; )
    {
        ULONG ret;
        enumerator->Next(WBEM_INFINITE, 1, &object, &ret);

        if( ret == 0) break;

        _variant_t variant;

        object->Get(L"Caption", 0, &variant, 0, 0);

        MessageBox(0, _bstr_t(variant), "The serial number is:", MB_OK);
    }

    return 0;
    //
    // TODO: check any call for errors
    //
}

Hope it helps.

I cannot find this file

The "WbemIdl.h" file is located in "Vc*\PlatformSDK\Include\WbemIdl.h" subdirectory of Visual Studio 2003 or 2005. Are you using another compiler? Or may be you have a reduced variant of Visual Studio.

WMI includes more header files, libraries and DLLs. In Windows 98, WMI has to be installed separately.

I think you would have to download WMI from Microsoft site.

And it would not be possible for me to move to Visual Studio .NET 2003 or higher.

1) Made the CopyProcessTh as a static in the class which returns UINT from the function which is recommended to terminate the thread.
OR
2) Seperate out the function from the class with following prototype

UINT CopyProcessTh(LPVOID pparam)
{
   //Do your Stuff here.
   return 0;
}

I can't made CopyProcessTh as a static cause it should operate with nonstatic members..

as for the 2nd...error C3867: 'CDlg::CopyProcessTh': function call missing argument list; use '&CDlg::CopyProcessTh' to create a pointer to member

You can't pass a non-static member function to _beginthread. The reason is that static and non-static member functions don't have the same prototype. Non-static member functions have an implicit parameter that is passed: the 'this' parameter. Look at the post of WhyteSky for the 'workaround' to this problem.

There was a recent change to C++ that says you can't write class_name::function_name to get a pointer to the function, you have to write &class_name::function_name
