How do we list out files in Recycle Bin (Windows 7)

In this post, I tried to enumerate files within recycle bin using a small Win32 program. As we know that recycle bin is a special folder on Windows File System. The location of this directory is not in the registry; it is marked with hidden and system attributes to prevent the user from moving or deleting it.

The steps to list out the contents of Recycle bin are as below:

1. It's a special folder denoted by CSIDL_BITBUCKET, which we need to pass to the function SHGetFolderLocation() method.

2. Source code snippet, I've avoided checks as much as possible to make the code simple and clean:

int _tmain(int argc, _TCHAR* argv[])
{
    LPITEMIDLIST pidlWinRecycleFiles    = NULL;
    LPITEMIDLIST pidlItems                = NULL;
    IShellFolder *psfWinRecycleFiles    = NULL;
    IShellFolder *psfDeskTop            = NULL;
    LPENUMIDLIST ppenum                    = NULL;
    STRRET strDispName;
    TCHAR pszParseName[MAX_PATH];
    ULONG celtFetched;
    HRESULT hr;

    hr = SHGetFolderLocation(NULL, CSIDL_BITBUCKET, NULL, NULL, &pidlWinRecycleFiles);
    hr = SHGetDesktopFolder(&psfDeskTop);
    hr = psfDeskTop->BindToObject(pidlWinRecycleFiles, NULL, IID_IShellFolder, (LPVOID *) &psfWinRecycleFiles);
    hr = psfDeskTop->Release();
    hr = psfWinRecycleFiles->EnumObjects(NULL,SHCONTF_FOLDERS | SHCONTF_NONFOLDERS, &ppenum);

    while( hr = ppenum->Next(1,&pidlItems, &celtFetched) == S_OK && (celtFetched) == 1)
    {
        // Name of file and folder in recycle bin
        psfWinRecycleFiles->GetDisplayNameOf(pidlItems, SHGDN_INFOLDER, &strDispName);
        StrRetToBuf(&strDispName, pidlItems, pszParseName, MAX_PATH);

        // Path of file
        psfWinRecycleFiles->GetDisplayNameOf(pidlItems, SHGDN_NORMAL, &strDispName);
        StrRetToBuf(&strDispName, pidlItems, pszParseName, MAX_PATH);
        PathRemoveFileSpec(pszParseName);
        CoTaskMemFree(pidlItems);
    }

    ppenum->Release();
    CoTaskMemFree(pidlWinRecycleFiles);
    psfWinRecycleFiles->Release();

    return 0;
}

We need to include the library 'Shlwapi.lib'.

Reversing char array without splitting the array to tokens

 I was reading about strdup, a C++ function and suddenly an idea came to my mind if this can be leveraged to aid in reversing a character array without splitting the array into words and reconstructing it again by placing spaces and removing trailing spaces. Again, I wanted an array to be passed as a function argument and an array size to be passed implicitly with the array to the function. Assumed, a well-formed char array has been passed into the function. No malformed array checking is done inside the function. So, the function signature and definition are like below: Below is the call from the client code to reverse the array without splitting tokens and reconstructing it. Finally, copy the reversed array to the destination.  For GNU C++, we should use strdup instead _strdup . On run, we get the following output: Demo code

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(

Close a Window Application from another application.

 This is just a demo application code to show how the WM_CLOSE message can be sent to the target process which has a titled window to close the application. To achieve this, either we can use SendMessage or PostMessage APIs to send required Windows messages to the target application. Though both the APIs are dispatching WM_XXXXX message to target application two APIs has some differences, these are as below: 1. SendMessage () call is a blocking call but PostMessage is a non-blocking call(Asynchronous) 2. SendMessage() APIs return type is LRESULT (LONG_PTR) but PostMessage() APIs return type is BOOL(typedef int). In Short, SendMessage () APIs return type depends on what message has been sent to the Windowed target process. For the other one, it's always a non-zero value, which indicates the message has been successfully placed on the target process message queue. Now let's see how can I close a target windowed application "Solitaire & Casual Games" from my custom-
