Microsoft Visual C++ .NET Chapter 9 Introduction to Windows Programming Objectives In this chapter you will learn: About Windows programming with Visual C++ About Windows architecture About the Windows API How to create a WinMain() function About events and messages Windows Programming with Visual C++ The ability to create Windows programs is one of the most important aspects of the Visual C++ environment There are two ways to create Windows programs in Visual C++: with C or C++ and the Windows application programming interface, or with C++ and Microsoft Foundation Classes An application programming interface, or API, is a library of methods and code that allows programmers to access the features and functionality of an application or operating system Windows Programming with Visual C++ The Windows API allows you to write programs for Windows operating systems You create Windows programs by combining code written in a source programming language with calls to the Windows API Although you can create Windows programs using C++ and the Windows API, with Visual C++ the preferred method of creating Windows programs is to use C++ with the Microsoft Foundation Classes Building a Windows Program Windows Programming with Visual C++ If the Microsoft Foundation Classes make the task of writing Windows programs with Visual C++ much easier, why bother to spend time learning how to create Windows API applications? The answer is because Microsoft Foundation Classes programming is built on Windows API programming You should already be more than familiar with the graphical user interface of Windows environments A graphical user interface, or GUI, is a graphically based environment that you use to interact with applications Windows Programming with Visual C++ To create a simple Windows API program, perform the steps listed on pages 469 and 470 SimpleApp Application Window Windows Architecture The term bit refers to a binary number of 0 or 1 The bus, or data bu
