| ======================================================================== | ||
| CONSOLE APPLICATION : project Project Overview | ||
| ======================================================================== | ||
|
|
||
| AppWizard has created this project application for you. | ||
|
|
||
| This file contains a summary of what you will find in each of the files that | ||
| make up your project application. | ||
|
|
||
|
|
||
| project.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. | ||
|
|
||
| project.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). | ||
|
|
||
| project.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 project.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. | ||
