C # SendKeys Usage

Function: sends one or more key messages to the active window as if it were entered on the keyboard.

Syntax: Sendkeys.send (string keys); Sendkeys.sendwait (string keys);

Description

(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 {{} and {}}.

(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}

DEL or DELETE	{DELETE} or {DEL}
Down ARROW	{Down}
