再发一个文字滚动，基于VB代码,很不错的VB源码，适合VB爱好者学习研究。(And then send a text to scroll through the VB code, it is a good VB source code for VB lovers learn.)

这是一个图书馆管理系统，包括图书信息，读者信息和对图书，读者的一些基本操作(This is a library management system, including information books, readers and information on books, readers, some of the basic operation)

实现一个界面，它能够非常完整的输出这样一个程序，我非常的喜欢他(The realization of an interface, it can be very complete output of such a procedure, I like him very much)

很好的BMP转JPG，有VB原代码及操作界面(good JPG, VB source code and user interface)

人脸识别程序，C++编写，图形界面挺简洁(Face recognition program, C++ written in very simple graphical interface)

说明：  许多现代浮点单元的一项主要体系结构功能，是能够将一个乘法与后面紧跟的加法作为单个运算执 行，且没有中间舍入误差。例如，Intel 的 Itanium 体系结构提供了一些指令，将三元运算 (a*b+c) 、(a*b-c) 和 (c-a*b) 中的每一个都组合为单个浮点指令（分别为 fma、fms 和 fnma）。这些单个 指令都比执行独立的乘法和加法指令快，并且因为没有中间乘法舍入，所以更为精确。该优化可以显 著提高那些含有多个交错乘法和加法运算的函数的速度(many modern floating point unit of a major system structure and function is to be a follow closely behind multiplication and addition of implementation as a single operator, with no intermediate rounding error. For example, Intel's Itanium architecture provides a number of directives to the ternary operator (a* b, c), (a* b-c) and (c-a* b) each have a portfolio to a single floating point instructions (Fullmetal respectively, and fms fnma) . These individual instruction than the implementation of an independent and additive multiplication instructions quickly, and because no middle multiplication into homes, so more precise. The optimization can significantly increase those containing more than staggered multiplication and addition operations function of the speed)

（1）定义一个抽象基类Shape,同它派生出5个类：圆、正方形、矩形、梯形、三角形。 （2）利用虚函数计算几种图形面积。 （3）演示构造函数、复制构造函数、析构函数的作用和调用顺序 （4）用类模板具体实现。 （5）利用MFC类库在图形用户界面上绘制及修改这些图形，采用对话框输入输出图形的基本属性，或者利用运算符重载输入输出图形的基本属性。 （6）用文件保存图形信息，且能够从文件中读取并作相应处理。 2）创新要求： 采用头文件与源文件分离的方法，多态性的实现多样化(defines an abstract base class Shape, with which it derives five categories: round, square, rectangular, trapezoidal, triangular. (2) the use of virtual functions to calculate several graphics area. Effect (3) demonstrate the constructor, copy constructor and destructor call sequence (4) with a class template implementation. (5) The use of MFC library to draw and modify graphics, using the basic properties dialog input and output graphics, or the use of the basic properties of operator overloading the input and output graphics on the graphical user interface. (6) with the file save graphical information, and can be read a file and make the appropriate treatment. 2) Innovation requirements: Using the method header and source files separate polymorphism diversify )

用VB做的，可以使文本框透明，这样就不影响美观了，十分好的资源，欢迎大家下载，用到了API(Do with VB, you can make the text box transparent, so as not to affect the appearance of very good resources, are welcome to download, use the API)

vb教程，窗体源码和vb的编程环境，可以学习一下思想(vb tutorial, opengl programming environment and vb)

vb实现的按钮与按钮之间的互相灰化，来屏蔽一些功能，主要代码(vb button and the button to achieve mutual between the ash to shield some of the features, the main code)
