open/search a folder when searching a directory

Code:

---

void dir()
{
    HANDLE hFind;
    WIN32_FIND_DATA FindData;
    int ErrorCode;
    BOOL Continue = TRUE;

    cout << "*.exe Files in WINDOWS directory." << endl << endl;

    hFind = FindFirstFile("C:\\Windows\\*.exe", &FindData);

    if(hFind == INVALID_HANDLE_VALUE)
    {
        ErrorCode = GetLastError();
        if (ErrorCode == ERROR_FILE_NOT_FOUND)
        {
            cout << "There are no files matching that path/mask\n" << endl;
        }
        else
        {
            cout << "FindFirstFile() returned error code " << ErrorCode << endl;
        }
        Continue = FALSE;
    }
    else
    {
        cout << FindData.cFileName << endl;
    }

    if (Continue)
    {
        while (FindNextFile(hFind, &FindData))
        {
            cout << FindData.cFileName << endl;
        }

        ErrorCode = GetLastError();

        if (ErrorCode == ERROR_NO_MORE_FILES)
        {
            cout << endl << "All files logged." << endl;
        }
        else
        {
            cout << "FindNextFile() returned error code " << ErrorCode << endl;
        }

        if (!FindClose(hFind))
        {
            ErrorCode = GetLastError();
            cout << "FindClose() returned error code " << ErrorCode << endl;
        }
    }
    cout << endl;
}

I used this script from a website.

How am I able to open and search a folder every time the program encounters one in the windows folder?

A common method is to call your method recursively if the file found has the directory flag attribute on. You would pass your method a path to the directory to enumerate.
