keyboard[마지막]

1. 연습장만들기

- 입력하는 글자를 출력

- Enter 시 줄바꿈

- BackSpace 시 지우기

- 라인 수 보이기

- 가로 길이, 세로 길이, 총 문자수 보이기

 

2. 소스

1) source.h

 

void my_input(HWND hWnd, HDC hdc, WPARAM wParam, TCHAR (*lpString)[100], int *nLength, int *size, int *y);
void my_paint(HDC hdc, int *nLength, int *size, int *y, TCHAR(*lpString)[100]);

 

2) source.cpp

 

#include "stdafx.h"
#include "practice2_3.h"
#include "source.h"
