================================================================================ MICROSOFT FOUNDATION CLASS LIBRARY : HWDetect Project Overview =============================================================================== The application wizard has created this HWDetect application for you. This application not only demonstrates the basics of using the Microsoft Foundation Classes but is also a starting point for writing your application. This file contains a summary of what you will find in each of the files that make up your HWDetect application. HWDetect.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. HWDetect.h This is the main header file for the application. It includes other project specific headers (including Resource.h) and declares the CHWDetectApp application class. HWDetect.cpp This is the main application source file that contains the application class CHWDetectApp. HWDetect.rc This is a listing of all of the Microsoft Windows resources that the program uses. It includes the icons, bitmaps, and cursors that are stored in the RES subdirectory. This file can be directly edited in Microsoft Visual C++. Your project resources are in 1033. res\HWDetect.ico This is an icon file, which is used as the application's icon. This icon is included by the main resource file HWDetect.rc. res\HWDetect.rc2 This file contains resources that are not edited by Microsoft Visual C++. You should place all resources not editable by the resource editor in this file. ///////////////////////////////////////////////////////////////////////////// The application wizard creates one dialog class: HWDetectDlg.h, HWDetectDlg.cpp - the dialog These files contain your CHWDetectDlg class. This class defines the behavior of your application's main dialog. The dialog's template is in HWDetect.rc, which can be edited in Microsoft Visual C++. ///////////////////////////////////////////////////////////////////////////// Other Features: ActiveX Controls The application includes support to use ActiveX controls. ///////////////////////////////////////////////////////////////////////////// Other standard files: StdAfx.h, StdAfx.cpp These files are used to build a precompiled header (PCH) file named HWDetect.pch and a precompiled types file named StdAfx.obj. Resource.h This is the standard header file, which defines new resource IDs. Microsoft Visual C++ reads and updates this file. HWDetect.manifest Application manifest files are used by Windows XP to describe an applications dependency on specific versions of Side-by-Side assemblies. The loader uses this information to load the appropriate assembly from the assembly cache or private from the application. The Application manifest maybe included for redistribution as an external .manifest file that is installed in the same folder as the application executable or it may be included in the executable in the form of a resource. ///////////////////////////////////////////////////////////////////////////// Other notes: The application wizard uses "TODO:" to indicate parts of the source code you should add to or customize. If your application uses MFC in a shared DLL, and your application is in a language other than the operating system's current language, you will need to copy the corresponding localized resources MFC70XXX.DLL from the Microsoft Visual C++ CD-ROM under the Win\System directory to your computer's system or system32 directory, and rename it to be MFCLOC.DLL. ("XXX" stands for the language abbreviation. For example, MFC70DEU.DLL contains resources translated to German.) If you don't do this, some of the UI elements of your application will remain in the language of the operating system. /////////////////////////////////////////////////////////////////////////////
