Upload In Asp

[saimonzz]

non sono un esperto di programmazione spero qualcuno possa aiutarmi
ho il seguente problema

riesco ad effettuare l'upload di file ad esempio immagini... di ogni tipo

MA NON APPENA FACCIO L'UPLOAD DI UNA PAGINA HTML sul fondo della pagina compare un 1 non capisco come eliminarlo...


l'upload richiama un file CLASS


<!--#INCLUDE file="upload.class"-->
<%
Dim oUpload
Dim oFile
Dim sFileName
Dim oFSO
Dim sPath
Dim sNewData
Dim nLength
Dim bytBinaryData


Const nForReading = 1
Const nForWriting = 2
Const nForAppending = 8

' grab the uploaded file data'
Set oUpload = New clsUpload
Set oFile = oUpload("File1")

' parse the file name'
sFileName = oFile.FileName

' Convert the binary data to Ascii'
bytBinaryData = oFile.BinaryData
nLength = LenB(bytBinaryData)
For nIndex = 1 To nLength
sNewData = sNewData & Chr(AscB(MidB(bytBinaryData, nIndex, 1)))
Next

' Save the file to the file system'
sPath = Server.MapPath("Uploads") & "/"
Set oFSO = Server.CreateObject("Scripting.FileSystemObject")
oFSO.OpenTextFile(sPath & sFileName, nForWriting, True).Write sNewData
Set oFSO = Nothing

Set oFile = Nothing
Set oUpload = Nothing
%>
File has been saved in file system. View this file:<BR><BR>
<A href="Uploads\<%=sFileName%>">Uploads\<%=sFileName %></A>


QUESTO è L'UPLOAD.CLASS
