Description: 当今社会是信息化的社会。为了适应社会对计算机数据安全保密越来越高的要求，美国国家标准局(NBS)于1997年公布了一个由IBM公司研制的一种加密算法，并且确定为非机要部门使用的数据加密标准，简称DES(Data Encrypton Standard)。自公布之日起，DES算法作为国际上商用保密通信和计算机通信的最常用算法，一直活跃在国际保密通信的舞台上，扮演了十分突出的角色。现将DES算法简单介绍一下，并给出实现DES算法的VC源代码。
DES算法由加密、解密和子密钥的生成三部分组成。-society today is the information society. In order to adapt to society for computer data security and confidentiality of the increasingly high demand the National Bureau of Standards (NBS), released in 1997 by an IBM developed an encryption algorithm, identified departments use non-confidential data encryption standard short DES (Data Encrypton Standard).

Description: 作者: junglesong
这是我过去进行一个OpenGL项目时使用到的\"三维空间向量/点\"类及相关函数,使用它们可以定义一个空间向量/点,实现向量的平移,缩放和旋转等,使用相关函数还可以实现两向量的叉乘,得到一个向量的绝对长度,将一个向量单位化,得到一个三点决定的平面的垂直向量(经过单位化),得到空间中两点的距离,得到两向量的点积,得到两向量的夹角等操作,为方便用户的使用,每个函数都有详细的注释,特别重要的向量计算如点积,叉乘还有相关说明,希望对大家有所用处.
由于源程序涉及到保密问题不能和盘托出,请见谅.

Description: vxworks 是调试用的核文件，不能烧写的FLASH里
vxWorks_romCompress.bin 是烧写到FLASH里的bin文件
IP 地址默认是 192.168.1.114 PC 机 要与开发板在同一网段才能通讯
在BIOS中启动vxworks很慢（由于没有开cache），要等10多秒用FLASHACCESS直接把vxworks
写进FLASH可以解决这个问题-vxworks use of nuclear documents not burning FLASH Lane vxWorks_romCompress.bin is burning to FL Lane joint effort of all advocates of the paper bin default IP address is 192.168.1.114 PC confidential and development on the same plate a network of communication can be activated in BIOS vxworks very slow (due to lack of open cache). have to wait more than 10 seconds with FLASHACCESS directly vxworks included FLASH can resolve this question

Description: “闪存(Flash)”这一名称，是源于该存储器件只需单步操作即能擦除其中所有内容的能力。军用装备很早就从这一能力中获益，军用装备都包含机密信息，一旦即将落入敌手，就应该迅速予以破坏。与EEPROM类似，Flash的数据存储也是通过向其晶体管栅区存入电荷来实现。电荷在栅上的存储是通过注入一定量的电荷、让其穿过绝缘氧化层来实现的。-"Flash (Flash)," the name, Memory is from the pieces of only single-step operation that can be erased in which all content capabilities. Military equipment from the very early benefit from this capability, military equipment contain confidential information, once the upcoming fall into an opponent, it should be quickly destroyed. And similar EEPROM, Flash data storage as well as through its gate transistors deposited in the district charge is to be achieved. Gate charge in the store is injected through a certain amount of the charge, so through the insulating oxide layer to achieve.

Description: 本代码按照DOD5220.22M标准来擦掉需要删除的机密数据，即首先将要删除的文件内容全部写为 0 ，再被写为 1 ，如此重复3次，接着被写上一个随机值；再加上一个DOD标准中未说明的步骤，即在删除文件之前，先将文件长度置为0，这使恢复机密文件的希望更为渺茫。-DOD5220.22M according to the code standards to wipe the need to remove confidential data, First, will be deleted all the content of the documents was made to 0, then wrote to a so repeat three times, are then written on a random value; coupled with a DoD standard unspecified steps to delete the file that is before given the length of documents home to 0, which makes restoring hope confidential documents of the more elusive.

Description: 一个GIS系统
（1） 程序编写环境为Visual Studio .NET 2002，也可以在Visual Studio .NET 2003中无需做任何修改打开并编译。
（2） 需要先在系统中安装MapObjects 2.0组件，或注册该组件，然后按书中的介绍加载该组件。MapObjects组件是ESRI公司提供的GIS二次开发组件，不是Visual Studio .NET本身自带的组件。
（3） 由于城市空间数据本身具有很高的价值，而且由于其保密性，不可能附带这些数据。-a GIS system (1) programming environment for Visual Studio.NET 200 2. also in Visual Studio.NET 2003 without any modifications to open and compiler.

ESRI MapObjects is provided by secondary development of GIS components, not Visual Studio.NET itself, bringing their components. (3) As the city itself has a spatial data of great value, but because of its confidential nature, these data can not be incidental.

Description: 电子公文传输系统就是为满足党政机关，行政职能部门,事业单位,大专院校,企业上报和下发公文需求，而开发的一套实用的系统。
电子公文传输管理系统实现无密级公文的网络传输、公文的签收，公文上报，实现网上会议签到，下载会议文件，通报发布等功能。整个系统技术成熟，安装配置简单，使用方便，系统稳定可靠，功能完善且灵活。从正常运行使用以来得到广大用户的支持和好评，以系统使用和维护简单，系统稳定为用户称道。
公文在各机关办公事务中是最繁杂又是最重要的事务，机关内部以及机关所属下级机关之间经常进行大量的公文接收与传送，一份文件有时候要印刷几十份，甚至上百份。大量文件的转发、传阅、发送、签收、审核让办公室里文件堆积如山，杂乱如麻，在这种公文处理过程中，要耗费相当大的人力与物力，而且重复劳动，量很大，办公效率较低。也许您现在以邮件方式来进行公文的传输，邮件发送公文的方式无法对公文进行统一备份，统一管理，也经常会出现文件感染病毒，接收反馈情况不能及时的获悉等弊端。
