VC++从DLL中获得资源的小实例源代码，从DLL中获得背景图像，可者是一个图标资源或是其它类型的文件，总之，学会了一种，就可以举一反三，灵活掌握了。(VC++ from the DLL resources, source code examples to get a background image from the DLL, can an icon resource, or other types of documents, in short, learned, you can learn by analogy, flexibility.)

说明：   本书作者根据自己学习C++的亲身体会及多年教学经验，用简单的例子和简练的叙述讲解C++编程，别具特色。 全书共分十八章（此为第10到12章），内容涉及对象的演化、数据抽象、隐藏实现、初始化与清除、函数重载与缺省参数、输入输出流介绍、常量、内联函数、命名控制、引用和拷贝构造函数、运算符重载、动态对象创建、继承和组合、多态和虚函数、模板和包容器类、多重继承、异常处理和运行时类型识别。 本书作为正式教材和自学用书均非常优秀，作为程序设计者的参考用书亦极为合适。 (Of this book to learn C++ based on their personal experience and years of teaching experience, using simple examples and concise narrative explaining C++ programming, unique. The book is divided into eighteen chapters, covering the evolution of objects, data abstraction, hiding implementation, initialization and removal, function overloading and default parameters, input and output streams introduced constants, inline functions, named control, reference and copy constructors, operator overloading, dynamic object creation, inheritance and composition, polymorphism and virtual functions, templates, and the container classes, multiple inheritance, exception handling and runtime type identification. Book as an official textbook, and a self-learning books are very good, as the programmer s reference book is also very appropriate.)
