텍스트 편집(입력) 컨트롤 - Win32

CreateWindow()
DestroyWindow()

사용자로 부터 키보드를 통해 문자열을 입력 받는다. // gets(), scanf()

최대 32K까지의 문자열을 편집(NT 이상에서는 제한이 없다)

디폴트 버퍼는 32K

ES_AUTOHSCROLL

WS_HSCROLL

ES_MULTILINE

ES_AUTOVSCROLL
WS_VSCROLL

ES_LEFT,ES_CENTER,EX_RIGHT
ES_NUMBER
ES_PASSWORD

한글 암호를 입력받을 수 없다.
대소문자는 구분
클립보드 동작도 제한

ES_READONLY
ES_UPPERCASE,ES_LOWERCASE
ES_WANTRETURN

EN_CHANGE

키보드 입력에 대한 통지를 하지 않는다.

시작점이 -1이면 선택이 해제
시작점과 끝점이 같으면 이 위치로 캐럿을 이동

EM_REPLACESEL

선택 영역(혹은 현재 위치)을 텍스트로 대체(삽입)
