在ASP中取得服务器网卡的MAC地址、DNS地址等网络…

前言，笔者由于前段时间要做一个MIS系统的开发，由于该MIS为一个非免费软件，故在完成该系统开发时相应的注册模块也须开发，由于为B/S结构的系统，所以在注册特征码的选择上我选择了独一无二的网卡MAC地址。闲话少说，下面切入正题。由于该系统属商业软件，故以下代码中仅包含代码思路，及简单的实现代码，具体大家可根据代码自由发挥，也可与我一起切磋。

'----------------------提取所有网卡的信息--------------------'

Public Function GetMacInfo()
On Error Resume Next

Dim fso, FileStr, AspSleepThread, CmdStr, SysDir, wshshell, CmdRe, MacFileContentFile, MacFileContent
Const MacFile = "TmpYesoulSoft001.LLP"
Set fso = Server.CreateObject("Scripting.FileSystemObject")

SysDir = Split(GlobalMod.GetSysDir, ",")(1)
If InStr(LCase(SysDir), "system32") = 0 Then
GetMacInfo = "本系统只能运行在Nt、Windows 2000、Windows.Net、Windows Xp、Windows 2003等32位系统下，不支持32位以下的系统！"

Exit Function
Else
CmdStr = SysDir "\Cmd.exe /C " SysDir "\Ipconfig.exe /All > " Server.MapPath(MacFile)
End If
CmdRe = Shell(CmdStr, vbHide)
If CmdRe <> 0 Then
Set MacFileContentFile = fso.OpenTextFile(Server.MapPath(MacFile), 1, False, TristateUseDefault)
'GetMacInfo = MacFileContentFile.ReadAll()
'Response.Flush
FileStr = MacFileContentFile.ReadAll()
MacFileContentFile.Close
Set MacFileContentFile = Nothing
Set AspSleepThread = Server.CreateObject("YesoulSoft.SleepThread")
'定义线程挂起的时间，这里为毫秒
AspSleepThread.SleepTime = 500
AspSleepThread.BeginSleepThread
GetMacInfo = ExecuteOne(FileStr, "Physical Address. . . . . . . . . : (.*)")
Set AspSleepThread = Nothing
Else
GetMacInfo = "系统当前无法获取您的网络信息，请检查权限继承关系后再运行本系统！"
Exit Function
End If
DelFile MacFile

Set fso = Nothing

End Function
'------------------在字符串匹配一次结果-------------------'
Public Function ExecuteOne(inpStr, PatStr)
Dim oRe, oMatch, oMatches
Set oRe = New RegExp
oRe.Pattern = PatStr
inpStr = LCase(inpStr)
oRe.IgnoreCase = True
Set oMatches = oRe.Execute(inpStr)
Set oMatch = oMatches(0)
ExecuteOne = oMatch.SubMatches(0)
End Function

代码中GETMACINFO函数仅仅可以获取首个网卡的MAC地址，至于DNS、网关等信息大家可以举一反三啊。
