如何把URL和邮件地址转换为超级链接？

Function InsertHyperlinks(inText)
Dim objRegExp, strBuf
Dim objMatches, objMatch
Dim Value, ReplaceValue, iStart, iEnd

  strBuf = ""
  iStart = 1
  iEnd = 1
  Set objRegExp = New RegExp

  objRegExp.Pattern = "\b(www|http|\S+@)\S+\b" 

' 判断URLs和emails.
  objRegExp.IgnoreCase = True                 

' 设置大小写不敏感..
  objRegExp.Global = True                     

' 全局适用.
  Set objMatches = objRegExp.Execute(inText)
  For Each objMatch in objMatches
    iEnd = objMatch.FirstIndex
    strBuf = strBuf & Mid(inText, iStart, iEnd-iStart+1)
    If InStr(1, objMatch.Value, "@") Then
      strBuf = strBuf & GetHref(objMatch.Value, "EMAIL", "_BLANK")
    Else
      strBuf = strBuf & GetHref(objMatch.Value, "WEB", "_BLANK")
    End If
    iStart = iEnd+objMatch.Length+1
  Next
  strBuf = strBuf & Mid(inText, iStart)
  InsertHyperlinks = strBuf
End Function

Function GetHref(url, urlType, Target)
Dim strBuf

  strBuf = "<a href="""
  If UCase(urlType) = "WEB" Then
    If LCase(Left(url, 3)) = "www" Then
      strBuf = "<a href=""URL:" & url & """超级链接:""" & _
              Target & """>" & url & "</a>"
    Else
      strBuf = "<a href=""" & url & """超级链接:""" & _

End Function
