在IE进行文档链接时,如果遇到OLE支持的文档,IE会自动调用相应程序打开它,有时候这种功能并不是我们所需的,虽然我们可以提醒用户用鼠标右键-->目标另存为....命令来下载文档,但这样毕竟不太友好,本文描述了利用FSO及Stream方法实现IE直接下载文档。<%@ language=vbscript codepage=65001%>

'Filename must be input
if Request(Filename)= then
response.write <h1>Error:</h1>Filename is empty!<p>
else
call downloadFile(replace(replace(Request(Filename),/,),/,))
Function downloadFile(strFile)
' make sure you are on the latest MDAC version for this to work
' get full path of specified file
strFilename = server.MapPath(strFile)
' clear the buffer
Response.Buffer = True
Response.Clear
' create stream
Set s = Server.CreateObject(ADODB.Stream)
s.Open
' Set as binary
s.Type = 1
' load in the file
on error resume next
' check the file exists
Set fso = Server.CreateObject(Scripting.FileSystemObject)
if not fso.FileExists(strFilename) then
Response.Write(<h1>Error:</h1>&strFilename& does not exists!<p>)
Response.End
end if
' get length of file
Set f = fso.GetFile(strFilename)
intFilelength = f.size
s.LoadFromFile(strFilename)
if err then
Response.Write(<h1>Error: </h1>Unknown Error!<p>)
Response.End
end if
' send the headers to the users Browse
Response.AddHeader Content-Disposition,attachment; filename=&f.name
Response.AddHeader Content-Length,intFilelength
Response.CharSet = UTF-8
Response.ContentType = application/octet-stream
' output the file to the browser
Response.BinaryWrite s.Read
Response.Flush
' tidy up
s.Close
Set s = Nothing
End Function
end if
