实现文件下载而不是由ie打开的代码。

答案：<%
Const ForReading=1
Const TristateTrue=-1 'Unicode
Const FILE_TRANSFER_SIZE=16384 '16k

'Use the following line for IIS4/PWS - this is the default for IIS5
Response.Buffer = True

Function TransferFile(path, mimeType, filename)
Dim objFileSystem, objFile, objStream
Dim char
Dim sent
send=0
TransferFile = True

Set objFileSystem = Server.CreateObject("Scripting.FileSystemObject")
Set objFile = objFileSystem.GetFile(Path)
Set objStream = objFile.OpenAsTextStream(ForReading, TristateTrue)

Response.AddHeader "content-type", mimeType
response.AddHeader "Content-Disposition","attachment;filename="&filename 
Response.AddHeader "content-length", objFile.Size

Do While Not objStream.AtEndOfStream
    char = objStream.Read(1)
    Response.BinaryWrite(char)
    sent = sent + 1
    If (sent MOD FILE_TRANSFER_SIZE) = 0 Then
        Response.Flush
        If Not Response.IsClientConnected Then
            TransferFile = False
            Exit Do
        End If
    End If
Loop

Response.Flush
If Not Response.IsClientConnected Then TransferFile = False

objStream.Close
Set objStream = Nothing
Set objFileSystem = Nothing
End Function

Dim path, mimeType, sucess
'Server.MapPath(path)
path = "C:\Inetpub\wwwroot\help.gif"
mimeType = "application/x-msdownload" 
sucess = TransferFile(path, mimeType,"help.gif")
Response.End
