+================================================================================
+    MICROSOFT 基础类库: VideoCapture 项目概述
+===============================================================================
+
+应用程序向导已为您创建此 VideoCapture 应用程序。此应用程序不仅演示使用 Microsoft 基础类的基本知识，而且可作为编写应用程序的起点。
+
+此文件包含组成 VideoCapture 应用程序的各个文件的内容摘要。
+
+VideoCapture.vcproj
+    这是使用应用程序向导生成的 VC++ 项目的主项目文件。
+    它包含有关生成文件的 Visual C++ 版本的信息，以及有关使用应用程序向导选择的平台、配置和项目功能的信息。
+
+VideoCapture.h
+    这是应用程序的主要头文件。它包括其他项目特定的头文件(包括 Resource.h)，并声明 CVideoCaptureApp 应用程序类。
+
+VideoCapture.cpp
+    这是包含应用程序类 CVideoCaptureApp 的主要应用程序源文件。
+
+VideoCapture.rc
+    这是程序使用的所有 Microsoft Windows 资源的列表。它包括 RES 子目录中存储的图标、位图和光标。此文件可以直接在 Microsoft Visual C++ 中进行编辑。项目资源位于 2052 中。
+
+res\VideoCapture.ico
+    这是用作应用程序图标的图标文件。此图标包括在主要资源文件 VideoCapture.rc 中。
+
+res\VideoCapture.rc2
+    此文件包含不是由 Microsoft Visual C++ 编辑的资源。您应该将不可由资源编辑器编辑的所有资源放在此文件中。
+
+
+/////////////////////////////////////////////////////////////////////////////
+
+应用程序向导创建一个对话框类:
+
+VideoCaptureDlg.h，VideoCaptureDlg.cpp - 对话框
+    这些文件包含 CVideoCaptureDlg 类。该类定义应用程序主对话框的行为。该对话框的模板位于 VideoCapture.rc 中，该文件可以在 Microsoft Visual C++ 中进行编辑。
+
+
+/////////////////////////////////////////////////////////////////////////////
+
+其他功能:
+
+ActiveX 控件
+    应用程序包括对使用 ActiveX 控件的支持。
+
+打印及打印预览支持
+    应用程序向导已通过从 MFC 库调用 CView 类中的成员函数，生成了用于处理打印、打印设置和打印预览命令的代码。
+
+/////////////////////////////////////////////////////////////////////////////
+
+其他标准文件:
+
+StdAfx.h, StdAfx.cpp
+    这些文件用于生成名为 VideoCapture.pch 的预编译头(PCH)文件和名为 StdAfx.obj 的预编译类型文件。
+
+Resource.h
+    这是标准头文件，它定义新资源 ID。
+    Microsoft Visual C++ 将读取并更新此文件。
+
+VideoCapture.manifest
+	Windows XP 使用应用程序清单文件描述应用程序	对特定版本并行程序集的依赖性。加载程序使用此	信息从程序集缓存加载相应程序集或	从应用程序加载私有信息。应用程序清单可能作为	与应用程序可执行文件安装在同一文件夹中的外部 .manifest 文件包括在内以便重新发布，	也可能以资源的形式包括在该可执行文件中。
+/////////////////////////////////////////////////////////////////////////////
+
+其他注释:
+
+应用程序向导使用“TODO:”指示应添加或自定义的源代码部分。
+
+如果应用程序在共享 DLL 中使用 MFC,则将需要重新发布 MFC DLL。如果应用程序所用与操作系统的区域设置不同，则也将必须重新发布对应的本地化资源 MFC90XXX.DLL。
+有关这两个主题的详细信息，请参阅 MSDN 文档中有关重新发布 Visual C++ 应用程序的部分。
