C#으로 CPU사용량 측정 프로그램 소스 코드입니다.
chart는 MS chart를 이용하였습니다.(MS chart를 이용하시려면 .net Framework 3.5 sp1, mschart관련 컴포넌트가 필요합니다..)

CheckSum Program

IP Datagram를 통하여 CheckSum 구해주는 프로그램
물론 에러는 무수하게 존재.. Show Data(binary)버튼을 누르게 되면.. 10진화된 데이터 그램을 아래에 2진화 시켜서 구해주게 됩니다. 그리고 Result Checksum을 누르게 되면 텍스트 박스에. 그림과 같은 수행결과를 보여주며 체크섬을 표시합니다.Visual Stduio 2008(.NET Framework 3.5기반)에서 제작되었습니다.
. 소스 공개는.. 부끄러워서 하지 않겠습니다.
. 프로그램에 문제 발생시 추 후 디버깅은 하지 않습니다..;;
