Physical Disk (HDD) Adapter Information.

In my previous post, I tried to build a command line app to show Physical Hard drives and volume(s) mapping for each HDD present/attached to a system. Now I've extended the program to read and display the properties of the storage adapter for each physical hard drive. To achieve this I've used the very popular Win32 API, CreateFile(), and IOCTL_STORAGE_QUERY_PROPERTY control code.

The previous program has been extended and now I'm showing only the part I've added on top of my previous program released under the title "PhysicalDisk and Volume Mapping information".

Here goes the rest of the code to get the storage adapter's information:

void PrintBusTypeName(BYTE iBusType)
{
    switch(iBusType)
    {
    case BusTypeUnknown:
        wprintf(L"BusType: Unknown\n");
        break;
    case BusTypeScsi:
        wprintf(L"BusType: SCSI\n");
        break;
    case BusTypeAtapi:
        wprintf(L"BusType: ATAPI\n");
        break;
    case BusTypeAta:
        wprintf(L"BusType: ATA\n");
        break;
    case BusType1394:
        wprintf(L"BusType: 1394\n");
        break;
    case BusTypeSsa:
        wprintf(L"BusType: SSA\n");
        break;

        break;

        wprintf(L"BusType: SATA\n");
        break;
    case BusTypeSd:
        wprintf(L"BusType: SD\n");
        break;
    case BusTypeMmc:
        wprintf(L"BusType: MMC\n");
        break;

        wprintf(L"BusType: Virtual\n");
        break;
    case BusTypeFileBackedVirtual:

        break;

        break;
    case BusTypeMaxReserved:

        break;
    default:
        break;
    }
}

In the _tmain....., called printAdapterPropertiesHDD from the following location.

:::::::::::::::::::::::::::::::::::::::::::::::::::

for( std::map < DWORD, DWORD >::iterator ii = mapPhysicaDriveCnt.begin(); ii != mapPhysicaDriveCnt.end(); ++ii)
        {
            wprintf(L"No. of volume(s) on physical drive %ld is/are: %ld\n", (*ii).first, mapDriveVolume.count((*ii).first));
           
            std::pair < std::multimap < DWORD, TCHAR * >::iterator, std::multimap < DWORD, TCHAR * >::iterator > ret;
            ret = mapDriveVolume.equal_range((*ii).first);
           
            for (std::multimap< DWORD, TCHAR * >::iterator it=ret.first; it!=ret.second; ++it)
            {
                wprintf(L"Volume on physical drive: %ld is: %s\n", it->first, it->second);
            }
            wprintf(L"\n");

            printAdapterPropertiesHDD((*ii).first);
        }

The output looks like the below:

Variadic template class to add numbers recursively during compilation

 The idea of having a class to add numbers (variable parameters) during compilation time recursively. Also wanted to restrict types to a single type while sending parameters to class member function. That said, if we mix int, float and double types to add function shall result in compilation error. How do we achieve this. The below is the code which actually helps to achieve this: <code> #include < fmt/format.h > template < typename T> class MyVarSumClass{     private :         T _sum = 0 ;     public :         template < typename ... TRest>         T add(T num, TRest... nums){             static_assert (std::conjunction<std::is_same<TRest, T>...>{}); /* Assert fails                if types are different */             _sum += num;             return add(nums...); // Next parameter packs gets picked recursively         }         // Base case         T add(T num){             _sum += num;             return _sum;         } }; int main() {     My

A simple approach to generate Fibonacci series via multi-threading

T his is a very simple approach taken to generate the Fibonacci series through multithreading. Here instead of a function, used a function object. The code is very simple and self-explanatory.  #include <iostream> #include <mutex> #include <thread> class Fib { public:     Fib() : _num0(1), _num1(1) {}     unsigned long operator()(); private:     unsigned long _num0, _num1;     std::mutex mu; }; unsigned long Fib::operator()() {     mu.lock(); // critical section, exclusive access to the below code by locking the mutex     unsigned long  temp = _num0;     _num0 = _num1;     _num1 = temp + _num0;     mu.unlock();     return temp; } int main() {     Fib f;          int i = 0;     unsigned long res = 0, res2= 0, res3 = 0;     std::cout << "Fibonacci series: ";     while (i <= 15) {         std::thread t1([&] { res = f(); }); // Capturing result to respective variable via lambda         std::thread t2([&] { res2 = f(); });         std::thread t3(

A concept to a product (Kimidori [ 黄緑]) - Part 2

In the previous part , we have seen KIMIDORI [ 黄緑] detect if a URL is malicious. In this part, we will see the details that KIMIDORI [ 黄緑] fetches out of the URL provided. As an example, provided a safe URL, https://www.azuresys.com/, and let's see what it brings out: As we can see, the link is safe and the link is active, which means we can just click on the link to open it on IE.  Now it's time to look into the URL report (still under development):  We have URLs IP, Location, and HTTP Status code. The Report part is a sliding window, the Show Report button shows as well as hides the report. Show / Hide Report is a toggle button. Let's see if we get the same details for any bad (phishing / malicious) URL: Took an URL example from a phishing link and tested it. The tool detected it as not a good link (Screen Shot Below) & link does not activate unlike a safe URL: Now let's see the report part for more details including domain registration details: It looks like it&
