Question

Ok so I have to run some queries in access 07 then compact and repair it. I am using python and win32com to do this. The code I’m currently using is this.

import os;
import win32com.client;
DB1 = 'db1.mdb'
DB2 = 'db1N.mdb'
DB3 = 'db2.mdb'
DBR = r'db1.mdb'
access = win32com.client.Dispatch("Access.Application")
access.OpenCurrentDatabase(DBR)
DB = access.CurrentDb()
access.DoCmd.OpenQuery("1")
access.DoCmd.OpenQuery("2")
access.DoCmd.OpenQuery("3")
access.CloseCurrentDatabase()
access.Application.Quit();
os.system('copy "db1.mdb" "db2.mdb"')
access = win32com.client.Dispatch("Access.Application")
access.CompactRepair(DB3,DB2)
access.Application.Quit();
os.remove("db2.mdb")
os.remove("db1.mdb")
os.rename("db1N.mdb","db1.mdb")

The problem is that I get this error.

WindowsError: [Error 32] The process cannot access the file because it is being used by another process: 'db1.mdb'

I dont know why I am getting this error seeing as I am quiting access which should close the file. Any Idea how to fix this would be greatly appreciated.

Your code includes this line:

DB = access.CurrentDb()

When that line executes, CurrentDb() references db1.mdb. Then you later get WindowsError at:

os.remove("db1.mdb")

So I’m wondering if the variable DB still holds a reference to db1.mdb. Perhaps you could first try del DB before os.remove().

Or, since your code isn’t actually using that DB variable, just get rid of it.
