Default save file in db with unique name or id with asp classic

I m new to asp my code is working absolutely fine, but i am facing two problems although these problems are not affecting the application. I just want to make good functionality to the application logically.

1) when i upload excel file, and if another file is already present with the same name, then new file overwrites it..
and if i manually change file name then file is saved with new name..
i am trying to save this new file with unique name or new name,, i don’t know how to do this pls help..

2) and second problem is that i want to save this file in db with the corresponding login user (for future reference).. i hope
my problems will be solved. many thanks

Code:
'upload_excel.asp               
<form action="upload_excel_process.asp" method="post" enctype="multipart/form-data" name="frmMain" onSubmit="return checkData();">

<%mem_id=session("mem_id")%>
<input type="hidden" name="client_id"  value="<%=mem_id%>">
</form>
process file

Code:
'upload_excel_process.asp
		 
<%client_id=session("mem_id")%>
<%
Dim xlApp,xlBook,xlSheet1,xlSheet2,OpenFile,i  
Dim Conn,strSQL,client_id,objExec  
Dim mySmartUpload  
Dim sFileName	

'*** Create Object ***'	
Set mySmartUpload = Server.CreateObject("aspSmartUpload.SmartUpload")

'*** Upload Files ***'
mySmartUpload.Upload

	'** Getfile Name ***'
sFileName = mySmartUpload.Files("file1").FileName

If sFileName <> "" Then

mySmartUpload.Files("file1").SaveAs(Server.MapPath("excel/"&sFileName))

'   my ref..\excel\" & session("mem_id") & "\" & now()

OpenFile = "excel/"&sFileName

'*** Create Exce.Application ***'

Set Conn = Server.Createobject("ADODB.Connection")
Conn.Open "DRIVER=Microsoft Access Driver (*.mdb);DBQ=" & Server.MapPath("../db/database.mdb"),"" , ""

simply, you need to create a unique string and use this for the filename. I use upload code that provides a function that will create a GUID. However here is a very quick, very simple way to apply a unique name which you can use for a file name:

Code:
Dim nRandom, theFileName
randomize
nRandom = (100-1)*Rnd+1
theFileName =monthname(month(date)) &  cstr(year(date)) & "_" & CStr(nRandom) & ".xls"


The output, as you can see will be MonthNameYearXXXXX (XXXX being the random unique part).

Your second issue is also very simple. You need to save what ever the unique identifyer is for the user to a new filed in the table where you are storing the fileName. I assign the ID field (which is an auto incrementing primary key) in my user table when the user logs in to a page level variable. Then this variable is passed from page to page and is inserted into the DB where ever applicable.
