用ASP+DLL实现WEB方式修改服务器时间
昨天一个朋友有个需求,是要通过WEB方式,修改IIS服务器上的时间,由于他的系统是ASP 3.0下开发的,所以本例子的代码是ASP的,不是ASP.NET,但是本人写这个文章是想抛砖引玉,毕竟编写程序关键的不是语言,更重要的是一种思想,把程序语言理解为一种工具,把编程思想理解为解决问题的思路和方法,那么编写出来的程序就是:利用“工具”按照解决问题的“思想”去解决一个问题。
首先,要感谢网友“小虎”,我是在网上看了他写的一篇关于用VB 6.0编写DLL组件FOR ASP的文章改写的,他的DLL代码只实现了改写小时和分钟,我增加了年、月、日、秒的修改。
首先,在VB 6.0中建立一个ActiveX Dll工程项目,信息如下:
工程名称:systimeset
类模块名称:timeset
VB 6.0的类模块代码如下:
1Option Explicit
2Private SystemTime As SystemTime
3Private Declare Function SetSystemTime()Function SetSystemTime Lib "kernel32" (lpSystemTime As SystemTime) As Long
4Private Type SystemTime
5 wYear As Integer
6 wMonth As Integer
7 wDayOfWeek As Integer
8 wDay As Integer
9 wHour As Integer
10 wMinute As Integer
11 wSecond As Integer
12 wMilliseconds As Integer
13End Type
14
15Dim tmp
16
17Private m_Hour As Integer
18Private m_Minute As Integer
19Private m_Year As Integer
20Private m_Month As Integer
21Private m_Day As Integer
22Private m_Second As Integer

79SystemTime.wMilliseconds = 0
80SystemTime.wMonth = Month
81SystemTime.wSecond = Second
82SystemTime.wYear = Year
83SystemTime.wHour = Hour
84SystemTime.wMinute = Minute
85setup = SetSystemTime(SystemTime)

关于DLL的注册,通常VB在本机上编译后,会自动将DLL注册;但如果你要放到IIS服务器上,请使用如下方法:
1、将systimeset.dll拷贝到c:\WINDOWS\system32下;
2、在开始菜单的运行里面输入:regsvr32 systimeset.dll (敲回车啊)
3、因为修改服务器的时间,INTERNET来宾帐户不具有该权限,设立权限请打开控制面版中的“管理工具”,然后打开“本地安全策略”--“用户权力指派”,双击“更改系统时间”,在弹出的对话框中点“添加用户或组”,将INETNET来宾帐户加入进来。
4、一切完毕后,将IIS服务重新启动一次。
在上面的设置完毕后,使用systimeset.dll组件的ASP代码页面如下:
将其编译为systimeset.dll的文件。
1<% @language="vbscript" %>
2<%
3function SetTime(strYear,strMonth,strDay)
4response.Expires=0
5set obj=server.createobject("systimeset.timeset")
6 obj.Year=strYear
7 obj.Month=strMonth
8 obj.Day=strDay
