You have been hired by an engineering company to develop software to perform advanced geometric calculation. Your new boss asked you to develop an application that allows engineers to calculate the surface area and the volume of a sphere. For this, you will need to use the following formulas.
Surface Area p = 4r2
Volume = 4/3 p r3
Remember p is equal to 3.14.
1.Allow the user to enter one value in the application (i.e., the radius value).
2.Use NumericUpdown controls to allow the user to enter the values.
3.Display the result in a text box and set it as read-only.
4.Make the Calculate button the Accept button.
5.Create a Clear button to clear the result text box and reset both NumericUpdown controls.
6.Create an Exit button.
7.Use labels to identify the input and output controls.
8.Create a radio button group that will allow the user to choose which calculation to perform in the application (surface area or volume).
9.Use a group box to enclose the radio buttons.
MICROSOFT FOUNDATION CLASS LIBRARY : geom3
AppWizard has created this geom3 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 geom3 application.
This file (the project file) contains information at the project level and
is used to build a single project or subproject. Other users can share the
project (.dsp) file, but they should export the makefiles locally.
This is the main header file for the application. It includes other
project specific headers (including Resource.h) and declares the
CGeom3App application class.
This is the main application source file that contains the application
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
This file contains information used by ClassWizard to edit existing
classes or add new classes. ClassWizard also uses this file to store
information needed to create and edit message maps and dialog data
maps and to create prototype member functions.
This is an icon file, which is used as the application's icon. This
icon is included by the main resource file geom3.rc.
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.
AppWizard creates one dialog class:
geom3Dlg.h, geom3Dlg.cpp - the dialog
These files contain your CGeom3Dlg class. This class defines
the behavior of your application's main dialog. The dialog's
template is in geom3.rc, which can be edited in Microsoft
Other standard files:
These files are used to build a precompiled header (PCH) file
named geom3.pch and a precompiled types file named StdAfx.obj.
This is the standard header file, which defines new resource IDs.
Microsoft Visual C++ reads and updates this file.
