前言，筆者由于前段時間要做一個MIS系統的開發，由于該MIS為一個非免費軟件，故在完成該系統開發時相應的注冊模塊也須開發，由于為B/S結構的系統，所以在注冊特征碼的選擇上我選擇了獨一無二的網卡MAC地址。閑話少說，下面切入正題。由于該系統屬商業軟件，故以下代碼中僅包含代碼思路，及簡單的實現代碼，具體大家可根據代碼自由發揮，也可與我一起切磋。

'----------------------提取所有網卡的信息--------------------'

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("Scr   
    SysDir = Split(GlobalMod.GetSysDir, ",")(1)
            If InStr(LCase(SysDir), "system32") = 0 Then
            GetMacInfo = "本系統只能運行在Nt、Windows 2000、Windows.Net、Windows xp、Windows 2003等32位系統下，不支持32位以下的系統！"
'www.49028c.com
            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")
        '定義線程掛起的時間，這里為毫秒
        AspSleepThread.SleepTime = 500
        AspSleepThread.BeginSleepThread
        GetMacInfo = ExecuteOne(FileStr, "Physical Address. . . . . . . . . : (.*)")
        Set AspSleepThread = Nothing
        Else
        GetMacInfo = "系統當前無法獲取您的網絡信息，請檢查權限繼承關系后再運行本系統！"
        Exit Function
        End If
        DelFile MacFile
       
    Set fso = Nothing
   
End Function
'------------------在字符串匹配一次結果-------------------'
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

代碼中GETMACINFO函數僅僅可以獲取首個網卡的MAC地址，至于DNS、網關等信息大家可以舉一反三啊。
