说明：  Diffie-Hellman:一种确保共享KEY安全穿越不安全网络的方法，它是OAKLEY的一个组成部分。Whitefield与Martin Hellman在1976年提出了一个奇妙的密钥交换协议，称为Diffie-Hellman密钥交换协议/算法(Diffie-Hellman Key Exchange/Agreement Algorithm).这个机制的巧妙在于需要安全通信的双方可以用这个方法确定对称密钥。然后可以用这个密钥进行加密和解密。但是注意，这个密钥交换协议/算法只能用于密钥的交换，而不能进行消息的加密和解密。双方确定要用的密钥后，要使用其他对称密钥操作加密算法实际加密和解密消息。(DH Protocol source code)

RFID 的实用例子,登陆使用了标准动态库类(Practical examples of RFID, landing the use of a standard type of dynamic libraries)

此工具用来检查DLL EXE OCX 等的依赖性，非常有用。当你OCX DLL注册不了时，请用这个检查试一下。 (This tool is used to check such as the DLL EXE OCX dependence, very useful. When you can not register OCX DLL, please try to use this check.)

说明：  课程设计的主要内容为开发一个实时绘制大规模三维场景的程序系统.必做部分： 1、学习3DS Max 的基本功能，并采用3DS Max 对三维场景进行建模，要求 场景中包含建筑物、道路、天空等基本元素，实现场景的纹理贴图功能。 2、通过3DS Loader 读取场景数据。。 3、学习并使用OpenGL 或DirectX 3D 实时绘制上述场景。 4、提供用户界面，并实现场景的交互漫游功能。 选做部分： 1、在场景中添加了三维地形。 2、实现雾这种气象条件的实时绘制。 3、实现计算机动画技术，飞机在天空中飞，圆环在不停的运转。 4、阴影的绘制 5、在场景中添加了喷泉。 6、实现Billboard 绘制技术。 7、添加了美妙的背景音乐。 (The main content of curriculum design for the development of a real-time rendering system of procedures for large-scale three-dimensional scene (running Interface, refer to Figure 1), including part and the election will be made part (where part of the requirements to achieve Optional 2 to 3 Or more than function). Will be part of: 1, learning the basic functions of 3DS Max, and three-dimensional scene using 3DS Max for modeling, requirements Scene includes buildings, roads, skies and other basic elements, to achieve the texture mapping function of the scene. 2, read the scene data by 3DS Loader. . 3, learn and use OpenGL or DirectX 3D real-time rendering the scene. 4, provide the user interface and interaction to achieve the scene roaming. Optional parts: 1, in the three-dimensional terrain scenes added. 2, the fog that weather conditions to achieve real-time rendering. 3, the realization of computer animation technology, aircraft flying in the sky, circle in)
