SampleWizard(tm) Instructions
-----------------------------
This CD contains all of the examples described in the book. Each
example is contained in a Visual C++ v5.0 project subdirectory with a
name that matches the example in the book. Each project subdirectory
also contains a \Wizard subdirectory that contains just the source
necessary to add that example to your application.
The SampleWizard(tm) utility uses these \Wizard subdirectories to
automatically add the source from an example directly to your
application.
The project for the SampleWizard utility is included on the CD.
Using the SampleWizard(tm)
--------------------------
Step One: Pick a Section
----------------------------
Pick the section of the book containing the type of example you're
looking for.
Step Two: Pick a Chapter
----------------------------
Pick the chapter in the book containing the type of example you're
looking for.
Step Three: Example
----------------------------
Pick the example you want.
Step 4: Setup
---------------
Determine how the example source will be inserted into your application:
<1> Enter the root directory that contains the examples from the book.
This can be the root directory of the CD drive itself, or if you copied
the examples to your disk, the directory which contains the examples on
your disk.
This entry will initially default to the location of the
SampleWizard.exe file. Any changes you make to this entry will be saved
in the system registry for the next time.
<2> Enter the directory to copy example files, if any. This entry
will be initialized to your current working directory.
<3> Enter a name to use to substitute for the "Wzd" marker found in all
example source files. It's recommended you use a two to five character
mneumonic.
Page 5 -- View Example and Insert
---------------------------------
The SampleWizard will display the Readme.wzd file found in the example
directory. You can:
<1> Simply read the file.
<2> Copy and paste sections of the displayed file into your source.
<3> Pick "Copy notes to clipboard." then press "Finish" to have the
entire displayed file copied to the clipboard.
<4> Pick "Copy any example files to target directory." then press
"Finish" to cause any example files to be copied into your application's
subdirectory.
Adding Your Own Examples
------------------------
If you would like to add your own example to the SampleWizard's
collection:
<1> Copy the book examples from the CD to a disk directory including the
SW.exe and SampWzd.ini files.
<2> Create a new subdirectory in this directory using a Uxx name where
xx is a sequential number.
<3> Add this Uxx name to the SampWzd.ini file in the "Chapter" you want
it to appear. Append it with a description of the sample. Make sur there is
at least one space between the Uxx name and the description.
<4> Add a \Wizard subdirectory to this new example subdirectory.
<5> Add a Readme.wzd file to the \Wizard directory describing the
example and using "Wzd" in any source snippets. (The "Wzd" can then be
substituted later by the SampleWizard.) Look at the other Readme.wzd
files for an idea.
<6> Copy any example files to the \Wizard directory. Filenames and class
names should again use the "Wzd" marker.
<7> Create a wzd.dir file in the \Wizard directory containing a list
of the example source files. If there won't be any example source files,
don't create a wzd.dir file.

【VC++ 入门:深入理解与实践】
Visual C++(简称VC++)是微软公司开发的一款集成开发环境,主要用于编写使用C++语言的应用程序。它不仅提供了编译器,还包括了调试器、资源编辑器等工具,为开发者提供了一个完整的开发平台。对于初学者而言,了解并掌握VC++的基本概念和使用方法是十分必要的。
1. **环境搭建**:你需要下载并安装Visual Studio,其中包含了VC++的开发环境。选择适合的版本,如Visual Studio Community Edition,它是免费且适合个人学习的版本。安装过程中,确保选中C++相关的组件。
2. **创建项目**:在VC++中,项目是代码组织的基本单位。通过“文件”->“新建”->“项目”来创建一个新的C++项目,可以选择Win32控制台应用或Windows Forms应用等模板,根据你的需求选择合适的项目类型。
3. **源代码编写**:在新建的项目中,你可以看到源代码文件(通常是main.cpp或cpp文件)。这里就是编写C++代码的地方。C++的基本语法包括变量声明、条件语句、循环语句、函数定义等,这些都是初学者需要掌握的基础知识。
4. **预处理指令**:在VC++中,预处理指令以`#`开头,如`#include`用于引入头文件,`#define`用于定义宏,`#pragma`用于设置编译器特定的指令。这些在实际编程中经常用到,尤其是`#include`,它是引入标准库和自定义头文件的关键。
5. **面向对象编程**:C++是一种支持面向对象编程的语言,类和对象是其核心概念。类是数据和操作的封装,而对象是类的实例。理解类的构造函数、析构函数、成员函数、继承、多态等概念对于深入学习VC++至关重要。
6. **异常处理**:在编程中,异常处理是必不可少的。C++使用`try`、`catch`和`throw`关键字进行异常处理。正确使用异常处理可以提高程序的健壮性。
7. **MFC库**:Microsoft Foundation Classes (MFC) 是VC++的一个重要部分,它提供了一套C++类库,方便开发Windows应用程序。如果你对用户界面编程感兴趣,MFC是一个很好的起点。
8. **资源管理**:在VC++中,可以使用资源编辑器来创建和管理窗口资源,如菜单、对话框、图标等。资源脚本文件(.rc)是存储这些资源的地方。
9. **调试技巧**:Visual Studio 提供强大的调试工具,如设置断点、查看变量值、单步执行等。学会利用这些工具可以帮助你定位和修复程序中的错误。
10. **性能优化**:对于标签中提到的"fft 程序",快速傅里叶变换(FFT)是一种高效的算法,常用于信号处理和图像分析等领域。在VC++中实现FFT,可能需要了解并使用库如Intel的MKL或者开源的FFTW。同时,掌握内存管理和多线程编程等技术,可以进一步提升程序的性能。
在学习过程中,通过阅读VC++的扩展编程实例,你可以更好地理解理论知识,并将其应用于实践中。不断地动手编程、调试和优化,是提升技能的关键。记得,编程是一项实践性很强的技能,理论与实践相结合才能走得更远。祝你在VC++的学习之旅中取得丰硕的成果!
