获取电脑系统函数_获取函数名

1.asp 获取对方操作系统的代码

2.用C程序查看linux/win操作系统信息

3.windows下C/C++如何获得当前主机的信息：操作系统版本、系统类型、CUP、网卡、内存和磁盘的利用率？

getpass。根据查询腾讯云官网显示，在Unix系统和Windows系统中，getpass函数会将密码输入框设置为不回显模式，用户输入的密码不会在屏幕上显示出来，getpass函数会将输入的密码存储在内存中，getpass直接从内存中读取windows密码。

asp 获取对方操作系统的代码

其实计算机二级并不难，大多为记忆性的知识，需要灵活运用的很少。所以，备考二级不宜太早，以考前一个半月开始准备为宜。

教材通读两遍

教材应至少通读两遍，把该记住（如变量、函数等）的都记牢，并不断复习巩固。

参考资料适当分类整理

参考资料不宜过多过杂，可根据考试大纲，对所做题型进行适当分类整理。

四大类题型

在二级考笔试中，一般有四大类，每一大类又有若干小类，包括计算机硬件和软件系统的常识，一些基础概念、数制、各种外设的常识、主机常识等，以及计算机最新发展的一些基本常识，如互联网、多媒体等。

DOS操作系统知识

二级考笔试中，DOS操作系统的知识也是必考的，如目录、路径，文件等知识。

程序阅读和理解

该语种的程序阅读和理解，一般是给一段小程序，要求考生理解其意义，或选择或填空。

ASP如何获取客户端操作系统版本

自定义函数：

function operationsystem() '操作系统版本

agent = Request.ServerVariables("HTTP_USER_AGENT")

if Instr(agent,"NT 5.1")>0 then

SystemVer="Windows XP"

elseif Instr(agent,"NT 5")>0 then

SystemVer="Windows 2000"

elseif Instr(agent,"NT 4")>0 then

SystemVer="Windows NT4"

elseif Instr(agent,"4.9")>0 then

SystemVer="Windows ME"

elseif Instr(agent,"98")>0 then

SystemVer="Windows 98"

elseif Instr(agent,"95")>0 then

SystemVer="Windows 95"

else

SystemVer="未知"

end if

operationsystem="操作系统: " & SystemVer

end function
