1、 计算机专业毕业设计 外文翻译 Visual C+ MFC 简要介绍 工 学 部 工学一部 专 业 计算机科学与技术 班 级 4418101 学 号 200413181038 姓 名 张 为 指导教师 史 俊 负责教师 沈阳航空工业学院 北方科技学院 2008 年 7 月 沈阳航空工业学院北方科技学院毕业设计 (外文翻译 ) 1 Introduction to MFC Programming with Visual C+ Version 6.x by Marshall Brain Visual C+ is much more than a compiler. It is a complete

2、application development environment that, when used as intended, lets you fully exploit the object oriented nature of C+ to create professional Windows applications. In order to take advantage of these features, you need to understand the C+ programming language. If you have never used C+, please tu

3、rn to the C+ tutorials in the C/C+ Tutorials page for an introduction. You must then understand the Microsoft Foundation Class (MFC) hierarchy. This class hierarchy encapsulates the user interface portion of the Windows API, and makes it significantly easier to create Windows applications in an obje

4、ct oriented way. This hierarchy is available for and compatible with all versions of Windows. The code you create in MFC is extremely portable. These tutorials introduce the fundamental concepts and vocabulary behind MFC and event driven programming. In this tutorial you will enter, compile, and run

5、 a simple MFC program using Visual C+. Tutotial 2 provides a detailed explanation of the code used in Tutorial 1. Tutorial 3 discusses MFC controls and their customization. Tutorial 4 covers message maps, which let you handle events in MFC. What is the Microsoft Foundations Class Library? Lets say y

6、ou want to create a Windows application. You might, for example, need to create a specialized text or drawing editor, or a program that finds files on a large hard disk, or an application that lets a user visualize the interrelationships in a big data set. Where do you begin? A good starting place i

7、s the design of the user interface. First, decide what the user should be able to do with the program and then pick a set of user interface objects accordingly. The Windows user interface has a number of standard controls, such as buttons, menus, scroll bars, and lists, that are already familiar to

8、Windows users. With this in mind, the programmer must choose a set of controls and decide how they should be arranged on screen. A time-honored procedure is to make a rough sketch of the proposed user interface (by tradition on a napkin or the back of an envelope) and play with the elements until th

9、ey feel right. For small projects, or for the early prototyping phase of a larger project, this is sufficient. The next step is to implement the code. When creating a program for any Windows 沈阳航空工业学院北方科技学院毕业设计 (外文翻译 ) 2 platform, the programmer has two choices: C or C+. With C, the programmer codes

10、at the level of the Windows Application Program Interface (API). This interface consists of a collection of hundreds of C functions described in the Windows API Reference books. For Windows NT, the API is typically referred to as the Win32 API, to distinguish it from the original 16-bit API of lower

11、-level Windows products like Windows 3.1. Microsoft also provides a C+ library that sits on top of any of the Windows APIs and makes the programmers job easier. Called the Microsoft Foundation Class library (MFC), this librarys primary advantage is efficiency. It greatly reduces the amount of code t

12、hat must be written to create a Windows program. It also provides all the advantages normally found in C+ programming, such as inheritance and encapsulation. MFC is portable, so that, for example, code created under Windows 3.1 can move to Windows NT or Windows 95 very easily. MFC is therefore the p

13、referred method for developing Windows applications and will be used throughout these tutorials. When you use MFC, you write code that creates the necessary user interface controls and customizes their appearance. You also write code that responds when the user manipulates these controls. For exampl

14、e, if the user clicks a button, you want to have code in place that responds appropriately. It is this sort of event-handling code that will form the bulk of any application. Once the application responds correctly to all of the available controls, it is finished. You can see from this discussion th

15、at the creation of a Windows program is a straightforward process when using MFC. The goal of these tutorials is to fill in the details and to show the techniques you can use to create professional applications as quickly as possible. The Visual C+ application development environment is specifically

16、 tuned to MFC, so by learning MFC and Visual C+ together you can significantly increase your power as an application developer. Windows Vocabulary The vocabulary used to talk about user interface features and software development in Windows is basic but unique. Here we review a few definitions to make discussion easier for those who are new to the environment. Windows applications use several standard user controls: Static text labels Push buttons
