+ 동적 연결 라이브러리 : hwcfilter 프로젝트 개요\r
+========================================================================\r
+\r
+응용 프로그램 마법사에서 이 hwcfilter DLL을 만들었습니다.\r
+\r
+hwcfilter 응용 프로그램을 구성하는 각 파일에 대한\r
+요약 설명이 포함되어 있습니다.\r
+\r
+\r
+hwcfilter.vcxproj\r
+ 응용 프로그램 마법사를 사용하여 생성한 VC++ 프로젝트의 기본 프로젝트 파일입니다.\r
+ 파일을 생성한 Visual C++ 버전에 대한 정보와 응용 프로그램 마법사를 사용하여 선택한 플랫폼,\r
+ 구성 및 프로젝트 기능에 대한 정보가 포함되어 있습니다.\r
+\r
+hwcfilter.vcxproj.filters\r
+ 응용 프로그램 마법사를 사용하여 생성된 VC++ 프로젝트의 필터 파일입니다. \r
+ 이 파일에는 프로젝트의 파일과 필터 간의 연결 정보가 들어 있습니다.\r
+ 이러한 연결은 특정 노드에서 유사한 확장명으로 그룹화된 파일을 표시하기 위해 IDE에서\r
+ 사용됩니다. 예를 들어 ".cpp" 파일은 "소스 파일" 필터와 연결되어 있습니다.\r
+\r
+hwcfilter.cpp\r
+ 기본 DLL 소스 파일입니다.\r
+\r
+/////////////////////////////////////////////////////////////////////////////\r
+기타 표준 파일:\r
+\r
+StdAfx.h, StdAfx.cpp\r
+ 이 파일은 미리 컴파일된 헤더(PCH) 파일 hwcfilter.pch와\r
+ 미리 컴파일된 형식(PCT) 파일 StdAfx.obj를 빌드하는 데 사용됩니다.\r
+\r
+/////////////////////////////////////////////////////////////////////////////\r
+기타 참고:\r
+\r
+응용 프로그램 마법사에서 사용하는 "TODO:" 주석은 사용자가 추가하거나 사용자 지정해야 하는\r
+소스 코드 부분을 나타냅니다.\r
