========================================================================
DYNAMIC LINK LIBRARY : NativeFuncs Project Overview
========================================================================

AppWizard has created this NativeFuncs DLL for you.

This file contains a summary of what you will find in each of the files that
make up your NativeFuncs application.


NativeFuncs.vcxproj
This is the main project file for VC++ projects generated using an Application Wizard.
It contains information about the version of Visual C++ that generated the file, and
information about the platforms, configurations, and project features selected with the
Application Wizard.

NativeFuncs.vcxproj.filters
This is the filters file for VC++ projects generated using an Application Wizard.
It contains information about the association between the files in your project
and the filters. This association is used in the IDE to show grouping of files with
similar extensions under a specific node (for e.g. ".cpp" files are associated with the
"Source Files" filter).

NativeFuncs.cpp
This is the main DLL source file.

When created, this DLL does not export any symbols. As a result, it
will not produce a .lib file when it is built. If you wish this project
to be a project dependency of some other project, you will either need to
add code to export some symbols from the DLL so that an export library
will be produced, or you can set the Ignore Input Library property to Yes
on the General propert page of the Linker folder in the project's Property
Pages dialog box.

/////////////////////////////////////////////////////////////////////////////
Other standard files:

StdAfx.h, StdAfx.cpp
These files are used to build a precompiled header (PCH) file
named NativeFuncs.pch and a precompiled types file named StdAfx.obj.

/////////////////////////////////////////////////////////////////////////////
Other notes:

AppWizard uses "TODO:" comments to indicate parts of the source code you
should add to or customize.
