MFC서버 통신용 클라이언트

에어버스 2015. 1. 20. 22:52

MFC서버는 MFC클라이언트와 통신하듯 char 버퍼에 저장해서 전송한다.
안드로이드와 통신한다고 해서 특별한 코드 추가는 없고, 한글도 잘된다.

MFC서버측에서 전송하는 코드

CString tmp;
tmp.Format("%s", szBuffer);
tmp = "02" + tmp;
char* szBuffer = (char*)(*(int*)&tmp);
pClient->Send(szBuffer, lstrlen(szBuffer));

안드로이드 코드
AndroidManifast.xml 에 아래 코드 추가, 인터넷 권한 부여
<uses-permission android:name="android.permission.INTERNET"/>

아래 소스대로 49, 52번 줄 내용과 같이 euc-kr 로 초기화 해줘야 했다. (한글 안깨짐)

단, 해당 통신 포트를 방화벽에서 열어줘야 한다.
윈도우10에서 Windows Defender 사용하면 MFC 서버 실행할때 오픈할건지 물어볼때 확인해주면 된다.
