팁 게시판에 있는 아래 자료를 참고로 Grid 내용을 excel로 저장하는 프로그램을 짜고 있습니다.
주로 number(8)을 많이 사용하는 데 Number(10)에 해당 하는 자료를 적용하니 에러가 납니다.
초보이다 보니 소스 분석이 좀 어려워서 어디를 고쳐야 할지 막막하네요.
고수님들의 도움 부탁드려요.

9999999999값을 XlsWriteCellNumber를 이용하여 excel로 전환하려고 하니
아래와 같은 오류가 발생하네요.

Project ***.exe raised exception class EConverError with message ''9999999999' is not a valid integer value'. Process stopped. Use Step or Run to continue.
