提供服务端登陆验证程序（验证码随机改变，防止非法进入）； 提供服务器控制程序，管理员可以允许、屏蔽和删除一个注册用户的登陆客户端； 任何改变访问地点的行为，都必须得到管理员的授权，否则无法登陆系统； 即使知道其他用户的密码也不能登陆系统。-provide certification services-landing procedures (Random Verification code change to prevent illegal entry); Provide server control procedures, administrators can allow, shielding and delete a user"s landing client; Any change in location of the visit have to be authorized administrators, whether while not landing systems; even if they know the password for other users can not landing system.

C_MD5 是一个用C写的标准MD5加密算法,使用简单，快速

存UTF8格式文件-deposit UTF8 format

除了上面提到的压缩方法，你也可以调用VB的工具MakeCab.exe（在VB5setupkitkitfil32或VB98WizardsPDWizard目录下）生成.cab文件。先构造一个Directive 文件(*.ddf)，然后使用Shell命令调用MakeCAB /f excel.ddf就可以生成*.cab文件。关于Directive 文件的格式，可以参考MSDN Library中的《MakeCAB: A Compression and Disk Layout Tool》一文。 -addition to the above-mentioned methods of compression, you can call VB Tools MakeCab.exe (VB5 setupkit kitfil32 or VB98 Wizards PDWizard directory) production. Cab document. First constructed a Directive document (*. DDF), then use the Shell order call MakeCAB/f excel.ddf can generate*. cab documents. Directive on the document format, they can refer to the MSDN Library "MakeCAB : A Disk Compression and Layout Tool," a text.
