Problem: Write a C/C++ program to create a folder in a specific directory path.

This task can be accomplished by using the mkdir() function. Directories are created with this function. (There is also a shell command mkdir which does the same thing). The mkdir() function creates a new, empty directory with name filename.

Note: A return value of 0 indicates successful completion, and -1 indicates failure.

Note: Above source codes would not run on online IDEs as the program requires the directory path in the system itself.

Directory Info. Create Метод

Определение

Создает каталог. Creates a directory.

Перегрузки

Создает каталог. Creates a directory.

Создает каталог с помощью объекта DirectorySecurity. Creates a directory using a DirectorySecurity object.

Create()

Создает каталог. Creates a directory.

Исключения

Не удалось создать каталог. The directory cannot be created.

Примеры

Следующий пример проверяет, существует ли указанный каталог, создает каталог, если он не существует, и удаляет каталог. The following example checks whether a specified directory exists, creates the directory if it does not exist, and deletes the directory.

Комментарии

Если каталог уже существует, этот метод не выполняет никаких действий. If the directory already exists, this method does nothing.

Если каталог не существовал до вызова этого метода, все кэшированные сведения об атрибуте каталога будут сброшены, если создание прошло успешно. If the directory did not exist before calling this method, then any cached attribute information about the directory will be flushed if the creation is successful.

Применяется к

Create(DirectorySecurity)

Создает каталог с помощью объекта DirectorySecurity. Creates a directory using a DirectorySecurity object.

Параметры

Элемент управления доступом, который необходимо применить к каталогу. The access control to apply to the directory.

Исключения

Каталог, заданный параметром path , доступен только для чтения или не является пустым каталогом. The directory specified by path is read-only or is not empty.

У вызывающего объекта отсутствует необходимое разрешение. The caller does not have the required permission.

path представляет собой строку нулевой длины, содержащую только пробелы или один или несколько недопустимых символов, заданных методом InvalidPathChars. path is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars.

path имеет значение null . path is null .

Указанный путь, имя файла или оба значения превышают максимальную длину, заданную в системе. The specified path, file name, or both exceed the system-defined maximum length.

Указан недопустимый путь (например, он ведет на несопоставленный диск). The specified path is invalid, such as being on an unmapped drive.

Предпринята попытка создать каталог с единственным знаком двоеточия (:). Creating a directory with only the colon (:) character was attempted.

Примеры

В следующем примере кода создается новый каталог внутри временной папки пользователя с указанными атрибутами безопасности каталога: The following code example creates a new directory inside the user’s temporary folder with the specified directory security attributes:

Комментарии

Используйте эту перегрузку метода для создания каталога с контролем доступа, поэтому нет возможности получить доступ к каталогу до применения безопасности. Use this method overload to create a directory with access control, so there is no chance the directory can be accessed before security is applied.

Если каталог уже существует, этот метод не выполняет никаких действий. If the directory already exists, this method does nothing.

Directory. Create Directory Method

Definition

Creates all the directories in a specified path.

Overloads

Creates all directories and subdirectories in the specified path unless they already exist.

Creates all the directories in the specified path, unless they already exist, applying the specified Windows security.

CreateDirectory(String)

Creates all directories and subdirectories in the specified path unless they already exist.

Parameters

The directory to create.

Returns

An object that represents the directory at the specified path. This object is returned regardless of whether a directory at the specified path already exists.

Exceptions

The directory specified by path is a file.

The network name is not known.

The caller does not have the required permission.

path is a zero-length string, contains only white space, or contains one or more invalid characters. You can query for invalid characters by using the GetInvalidPathChars() method.

path is prefixed with, or contains, only a colon character (:).

The specified path, file name, or both exceed the system-defined maximum length.

The specified path is invalid (for example, it is on an unmapped drive).

path contains a colon character (:) that is not part of a drive label («C:\»).

Examples

The following example creates and deletes the specified directory:

To create the directory C:\Users\User1\Public\Html when the current directory is C:\Users\User1, use any of the following calls to ensure that the backslash is interpreted properly:

Remarks

Any and all directories specified in path are created, unless they already exist or unless some part of path is invalid. If the directory already exists, this method does not create a new directory, but it returns a DirectoryInfo object for the existing directory.

The path parameter specifies a directory path, not a file path.

Trailing spaces are removed from the end of the path parameter before creating the directory.

You can create a directory on a remote computer, on a share that you have write access to. UNC paths are supported; for example, you can specify the following for path : \\2009\Archives\December in Visual Basic, and \\\\2009\\Archives\\December in C#.

Creating a directory with only the colon character (:) is not supported, and will cause a NotSupportedException to be thrown.

On Unix systems, use a forward slash (/) as path separator.

Applies to

CreateDirectory(String, DirectorySecurity)

Creates all the directories in the specified path, unless they already exist, applying the specified Windows security.

Parameters

The directory to create.

The access control to apply to the directory.

Returns

An object that represents the directory at the specified path. This object is returned regardless of whether a directory at the specified path already exists.

Exceptions

The directory specified by path is a file.

The network name is not known.

The caller does not have the required permission.

The specified path is invalid (for example, it is on an unmapped drive).

path contains a colon character (:) that is not part of a drive label («C:\»).

Examples

The following example creates a new directory with access rules for two user accounts.

Remarks

Use this method overload to create a directory with access control, so there is no chance the directory can be accessed before security is applied.

Any and all directories specified in the path parameter are created, unless they already exist or unless some part of path is invalid. The path parameter specifies a directory path, not a file path. If the directory already exists, this method does not create a new directory, but it returns a DirectoryInfo object for the existing directory.

You can create a directory on a remote computer, on a share that you have write access to. UNC paths are supported; for example, you can specify the following for path : \\2009\Archives\December in Visual Basic, and \\\\2009\\Archives\\December in C#.

Creating a directory with only the colon character (:) is not supported and causes a NotSupportedException to be thrown.

CreateDirectoryExA function (winbase.h)

Creates a new directory with the attributes of a specified template directory. If the underlying file system supports security on files and directories, the function applies a specified security descriptor to the new directory. The new directory retains the other attributes of the specified template directory.

To perform this operation as a transacted operation, use the CreateDirectoryTransacted function.

Syntax

Parameters

The path of the directory to use as a template when creating the new directory.

In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to 32,767 wide characters, call the Unicode version of the function and prepend «\?» to the path. For more information, see Naming a File.

The path of the directory to be created.

In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to 32,767 wide characters, call the Unicode version of the function and prepend «\?» to the path. For more information, see Naming a File.

A pointer to a SECURITY_ATTRIBUTES structure. The lpSecurityDescriptor member of the structure specifies a security descriptor for the new directory.

If lpSecurityAttributes is NULL, the directory gets a default security descriptor. The access control lists (ACL) in the default security descriptor for a directory are inherited from its parent directory.

The target file system must support security on files and directories for this parameter to have an effect. This is indicated when GetVolumeInformation returns FS_PERSISTENT_ACLS.

Return value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero (0). To get extended error information, call GetLastError. Possible errors include the following.

Return code	Description
ERROR_ALREADY_EXISTS	The specified directory already exists.
ERROR_PATH_NOT_FOUND	One or more intermediate directories do not exist. This function only creates the final directory in the path. To create all intermediate directories on the path, use the SHCreateDirectoryEx function.

Remarks

The CreateDirectoryEx function allows you to create directories that inherit stream information from other directories. This function is useful, for example, when you are using Macintosh directories, which have a resource stream that is needed to properly identify directory contents as an attribute.

Some file systems, such as the NTFS file system, support compression or encryption for individual files and directories. On volumes formatted for such a file system, a new directory inherits the compression and encryption attributes of its parent directory.

You can obtain a handle to a directory by calling the CreateFile function with the FILE_FLAG_BACKUP_SEMANTICS flag set. For a code example, see CreateFile.

To support inheritance functions that query the security descriptor of this object can heuristically determine and report that inheritance is in effect. For more information, see Automatic Propagation of Inheritable ACEs.

In WindowsВ 8 and Windows ServerВ 2012, this function is supported by the following technologies.

Technology	Supported
Server Message Block (SMB) 3.0 protocol	Yes
SMB 3.0 Transparent Failover (TFO)	Yes
SMB 3.0 with Scale-out File Shares (SO)	Yes
Cluster Shared Volume File System (CsvFS)	Yes
Resilient File System (ReFS)	Yes

В

The winbase.h header defines CreateDirectoryEx as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.

Создание вложенной папки (Directory)

Добрый день, появилась необходимость создать вложенную папку в среде windows XP

нашел тока
#include
CreateDirectory((LPCTSTR)»c:\\new»,NULL); // но данный код не работает почему-то, к тому же я так понял проблема с преоразованием в LPCTSTR из char* или string

у меня есть путь в переменной std::string path = «C:\\test\01\01»; , приэтом папки C:\\test еще нету, необходимо создать много папок в в папке C:\\test

помогите поажулуста с написанием правильного кода на MS VC++ 8.0

Стереть содержимое папки, за исключением одной вложенной папки
В лаборатории стоят комьютеры. Посетители постоянно копируют на компьютеры в папку d:\shared\.

Прочитать стили из вложенной папки
страницы читает из папки templates(я имею ввиду, что считает как корневую), а вот стили находятся в.

Получить название вложенной папки
Есть папка folder. В ней всякие картинки и вложенная папка folder2. Через scandir получаю.

Создание вложенной рамки
Нужно чтобы внутренняя рамка сверху и сбоку отступала на определённое расстояние, как на рисунке .

Я б конечно использовал средства boost, там куда удобнее, и код получится портируемым. на форуме даже выкладывал свою версию, т.к. в стандартной поставке функция оказалась нерабочей.

но раз нужно на winapi, предлагаю такой вариант.

Если можно без WinAPI и boost, то вот. Единственное — не знаю, как MS VC++ 8.0 отнесётся к местной mkdir (её убили в VC++ 2005, отказавшись от POSIX). Если что — уберите параметр mode_t mode и используйте либо _mkdir, либо CreateDirectoryA:

Заказываю контрольные, курсовые, дипломные и любые другие студенческие работы здесь или здесь.
