Очистка экрана Clearing the Screen

Существует четыре способа очистки экрана в консольном приложении. There are four ways to clear the screen in a console application.

Пример 1 Example 1

Это рекомендуемый метод с использованием виртуальных последовательностей терминалов для всех новых разработок. This is the recommended method using virtual terminal sequences for all new development. Дополнительные сведения см. в обсуждении классических API консоли и виртуальных последовательностей терминалов . For more information, see the discussion of classic console APIs versus virtual terminal sequences .

Первый способ — настроить приложение для виртуальных выходных последовательностей терминала, а затем вызвать команду «очистить экран». The first method is to set your application up for virtual terminal output sequences and then call the «clear screen» command.

Дополнительные варианты этой команды см. в документации по виртуальным последовательностям, посвященной стиранию экрана . You can find additional variations on this command in the virtual terminal sequences documentation on Erase In Display .

Пример 2 Example 2

Второй метод — написать функцию для прокрутки содержимого экрана или буфера и задать заливку для видимого пространства. The second method is to write a function to scroll the contents of the screen or buffer and set a fill for the revealed space.

Это соответствует поведению командной строки cmd.exe . This matches the behavior of the command prompt cmd.exe .

Пример 3 Example 3

Третий метод заключается в написании функции для программного очистки экрана с помощью функций филлконсолеаутпутчарактер и филлконсолеаутпутаттрибуте . The third method is to write a function to programmatically clear the screen using the FillConsoleOutputCharacter and FillConsoleOutputAttribute functions.

Этот прием показан в следующем образце кода. The following sample code demonstrates this technique.

Windows cmd clear command

Starts a new instance of the command interpreter, Cmd.exe. If used without parameters, cmd displays the version and copyright information of the operating system.

Syntax

Parameters

Parameter	Description
/c	Carries out the command specified by string and then stops.
/k	Carries out the command specified by string and continues.
/s	Modifies the treatment of string after /c or /k.
/q	Turns the echo off.
/d	Disables execution of AutoRun commands.
/a	Formats internal command output to a pipe or a file as American National Standards Institute (ANSI).
/u	Formats internal command output to a pipe or a file as Unicode.
/t: < | >	Sets the background (b) and foreground (f) colors.
/e:on	Enables command extensions.
/e:off	Disables commands extensions.
/f:on	Enables file and directory name completion.
/f:off	Disables file and directory name completion.
/v:on	Enables delayed environment variable expansion.
/v:off	Disables delayed environment variable expansion.
Specifies the command you want to carry out.
/?	Displays help at the command prompt.

The following table lists valid hexadecimal digits that you can use as the values for and :

Value	Color

5	Purple
6	Yellow
7	White
8	Gray
9	Light blue

Remarks

To use multiple commands for , separate them by the command separator && and enclose them in quotation marks. For example:

If you specify /c or /k, cmd processes, the remainder of string, and the quotation marks are preserved only if all of the following conditions are met:

You don’t also use /s.

You use exactly one set of quotation marks.

You don’t use any special characters within the quotation marks (for example: & ( ) @ ^ | ).

You use one or more white-space characters within the quotation marks.

The string within quotation marks is the name of an executable file.

If the previous conditions aren’t met, string is processed by examining the first character to verify whether it is an opening quotation mark. If the first character is an opening quotation mark, it is stripped along with the closing quotation mark. Any text following the closing quotation marks is preserved.

If you don’t specify /d in string, Cmd.exe looks for the following registry subkeys:

HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun\REG_SZ

HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun\REG_EXPAND_SZ

If one or both registry subkeys are present, they’re executed before all other variables.

Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.

You can disable command extensions for a particular process by using /e:off. You can enable or disable extensions for all cmd command-line options on a computer or user session by setting the following REG_DWORD values:

HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\EnableExtensions\REG_DWORD

HKEY_CURRENT_USER\Software\Microsoft\Command Processor\EnableExtensions\REG_DWORD

Set the REG_DWORD value to either 0Г—1 (enabled) or 0Г—0 (disabled) in the registry by using Regedit.exe. User-specified settings take precedence over computer settings, and command-line options take precedence over registry settings.

Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.

When you enable command extensions, the following commands are affected:

assoc

call

chdir (cd)

color

del (erase)

endlocal

for

ftype

goto

if

mkdir (md)

popd

prompt

pushd

set

setlocal

shift

start (also includes changes to external command processes)

If you enable delayed environment variable expansion, you can use the exclamation point character to substitute the value of an environment variable at run time.

File and directory name completion is not enabled by default. You can enable or disable file name completion for a particular process of the cmd command with /f:<on | off>. You can enable or disable file and directory name completion for all processes of the cmd command on a computer or for a user logon session by setting the following REG_DWORD values:

HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\CompletionChar\REG_DWORD

HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\PathCompletionChar\REG_DWORD

HKEY_CURRENT_USER\Software\Microsoft\Command Processor\CompletionChar\REG_DWORD

HKEY_CURRENT_USER\Software\Microsoft\Command Processor\PathCompletionChar\REG_DWORD

To set the REG_DWORD value, run Regedit.exe and use the hexadecimal value of a control character for a particular function (for example, 0Г—9 is TAB and 0Г—08 is BACKSPACE). User-specified settings take precedence over computer settings, and command-line options take precedence over registry settings.

Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.

If you enable file and directory name completion by using /f:on, use CTRL+D for directory name completion and CTRL+F for file name completion. To disable a particular completion character in the registry, use the value for white space [0Г—20] because it is not a valid control character.

Pressing CTRL+D or CTRL+F, processes the file and directory name completion. These key combination functions append a wildcard character to string (if one is not present), builds a list of paths that match, and then displays the first matching path.

If none of the paths match, the file and directory name completion function beeps and does not change the display. To move through the list of matching paths, press CTRL+D or CTRL+F repeatedly. To move through the list backwards, press the SHIFT key and CTRL+D or CTRL+F simultaneously. To discard the saved list of matching paths and generate a new list, edit string and press CTRL+D or CTRL+F. If you switch between CTRL+D and CTRL+F, the saved list of matching paths is discarded and a new list is generated. The only difference between the key combinations CTRL+D and CTRL+F is that CTRL+D only matches directory names and CTRL+F matches both file and directory names. If you use file and directory name completion on any of the built-in directory commands (that is, CD, MD, or RD), directory completion is assumed.

File and directory name completion correctly processes file names that contain white space or special characters if you place quotation marks around the matching path.

You must use quotation marks around the following special characters: & [ ] | < >^ = ; ! ‘ + , `

If the information that you supply contains spaces, you must use quotation marks around the text (for example, «Computer Name»).

If you process file and directory name completion from within string, any part of the path to the right of the cursor is discarded (at the point in string where the completion was processed).
