CONSOLE APPLICATION : Keps Project Overview
|
||||
========================================================================
|
||||
|
||||
AppWizard has created this Keps application for you.
|
||||
|
||||
This file contains a summary of what you will find in each of the files that
|
||||
make up your Keps application.
|
||||
|
||||
|
||||
Keps.vcproj
|
||||
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.
|
||||
|
||||
Keps.cpp
|
||||
This is the main application source file.
|
||||
|
||||
/////////////////////////////////////////////////////////////////////////////
|
||||
Other standard files:
|
||||
|
||||
StdAfx.h, StdAfx.cpp
|
||||
These files are used to build a precompiled header (PCH) file
|
||||
named Keps.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.
