C # Analog keyboard operation--sendkey (), SendKeys ()

 

The analog keyboard input is implemented using the following 2 syntaxes.
Sendkeys.send (string keys); Analog kanji (text) input
Sendkeys.sendwait (string keys); Analog Key input

Let's take a look at the usage of the 2 syntax! Post the code later to see if you can read it.

(1) Each key is represented by one or more characters. In order to specify a single keyboard character, you must press the key of the character itself. For example, to represent the letter A, you can use "a" as a string. To represent more than one character, you must precede the character with a second character. For example, to represent A, B, and C, you can use "ABC" as a string.

(2) for SendKeys, the plus (+), caret (^), percent sign (%), underscore (~), and parenthesis () have special meanings. To specify any one of these characters, place it in curly braces ({}). For example, to specify a positive sign, you can use {+}. square brackets ([]) do not have a special meaning for SendKeys, but they must be placed in curly braces. In other applications, square brackets have a special meaning, which can be significant in the event of Dynamic Data Exchange (DDE). To specify curly brace characters, use {}.

(3) To specify characters that do not appear when you press a key, such as ENTER or TAB and those that represent an action other than a character, use the following code:

Keys	Code
BACKSPACE	{BACKSPACE}, {BS}, or {BKSP}
Break	{Break}
CAPS LOCK	{CAPSLOCK}
DEL or DELETE	{DELETE} or {DEL}
Down ARROW	{Down}
END	{END}
ENTER	{ENTER} or ~
Esc	{ESC}
Help	{Help}
HOME	{HOME}
INS or INSERT	{INSERT} or {INS}
Left ARROW	{left}
NUM LOCK	{NumLock}
PAGE down	{PGDN}
PAGE up	{PgUp}
PRINT screen	{PRTSC}
Right ARROW	{Right}
SCROLL LOCK	{ScrollLock}
TAB	{TAB}
Up ARROW	{Up}
F1	{F1}
F2	{F2}
F3	{F3}
F4	{F4}
F5	{F5}
F6	{F6}
F7	{F7}
F8	{F8}
F9	{F9}
F10	{F10}
F11	{F1}
F12	{F12}
F13	{F13}
F14	{F14}
F15	{F15}
F16	{F16}

(4) Key combinations such as SHIFT, CTRL and ALT can place one or more code in front of these key codes, which are listed as follows:

Keys	Code
Shift	+
Ctrl	^
Alt	%

(5) Input Chinese characters with sendkeys.send ("kanji");
