1。数据库表布局(Access)：
UserID:Text(保留上传文件的用户ID)
FileContentType:Text(用来保留上传文件的类型，eg:"Application/msword"，次要用来利用户能准确下载此文件）
FileContent:OLE Object（保留文件数据）
2。HTML文件
muploadfile.htm
<Form name="upload_file" enctype="multipart/form-data" action="muploadfile.asp" method=post>
<input type=hidden name="UserID" value="abc">
<input type=hidden name="FileUploadStart"> '这里用来暗示入手下手文件数据上传
File to send: <BR>
<INPUT TYPE="file" name="file_up" size="30"><br>
<INPUT TYPE="file" name="file_up" size="30"><br>
<input type=hidden name="FileUploadEnd"> '这里用来暗示文件数据停止
<input type=submit value=Submit>
</Form>
3。ASP文件
muploadfile.asp
<%
Response.Expires=0

End If
Next
End If

End Function
'判别文件数据时分入手下手
If strComp(strFieldName,"FileUploadStart",1)=0 Then
binHTTPHeader=MIDB(binHTTPHeader,INSTRB( DataStart + 1, binHTTPHeader, divider ))
exit do
End if
