[vicio]

<%
Function GetFileName(ByVal strFile)
If strFile <> "" Then
GetFileName = mid(strFile,InStrRev(strFile, "\")+1)
Else
GetFileName = ""
End If
End function
strFileName = Request.Form("file1")
Set objStream = Server.CreateObject("ADODB.Stream")
objStream.Type = 1 ' adTypeBinary
objStream.Open
objStream.LoadFromFile strFileName
objStream.SaveToFile Server.MapPath("sc/"&GetFileName(strFileName)),2
objStream.Close
response.Write "<script language=javascript>alert('你的上传成功！');history.go(-1);</script>"
%>
怎么在里面加入代码对上传的文件进行重命名！
