파일을 직접 윈도우명령을 이용하여 휴지통에 넣는 방법입니다.
원문은 http://www.cpearson.com 에 있습니다.

전에도 말씀드렸다시피 VB에서는 Kill이라는 명령어를 제공합니다. 이것은 파일을 그대로 지워버립니다. 문제는 휴지통에 보내면서 지우는게 아니라 그냥 지웁니다.
쉬운 방법으로는 지운후 복구할 수 없습니다.
그러나 윈도우 API를 이용하면 파일을 휴지통으로 보낼수 있습니다.
이 명령어와 관련하여 세가지 프로시져를 제공하고 있습니다.
1. 파일을 휴지통으로 보내기(Recycle)
2. 파일을 중요한 파일인지 검사하고 안전하게 휴지통으로 보내기(RecycleSafe)
3. 휴지통 비우기(EmptyRecycleBin)
주의할 점은 파일을 지정할때 드라이브명부터 파일명까지 완전하게 넣어줘야 한다는 것입니다.
C:\Some\Folder\File.xls 이렇게 넣어야 인식하고 처리하게 됩니다.
여기서는 1번 프로시져와 관련된 부분만 붙여놓겠습니다.
공통부분입니다.
