I am trying to use VBA to backup the BACK-END of a split database (so I can automatically archive selected data). If I use FileCopy I get a message that the BACK-END database has not been found.Obviously I could 'unlink' the BACK-END, copy it and 're-link' it..Is it possible to copy the BACK-END tables(not just the links) into the FRONT-END and get at them that way?
View RepliesI have a split database. I have secured the mde sufficiently but I need to secure the back end so that no one could link to tables in it. If I introduce a password to the back end is this going to require those using front end to supply the password? If not then this could be good solution.
As the database is on the network drive, is there any other way to prevent people to link to the db? Can I hide the db in the network drive? Or should I hide tables in the BE. Should these still be available to be linked?
I have designed a split database( with back end and front end), I am just wondering what would be the best way to put a password for both of the back and front end.

Added a new table to the back end .But do not know how to update it to the front end
We are currently running a FE / BE splitted database abd would like to back the back end up (to a sepearate location) every 15 minuutes by using the On Timer event.
Troiuble is, I believe I cant use the CopyDataBaseFile method whilst other users are in it and it would be too much hassle kicking everyone off!
Manually copying and pasting is good, but would really like to crack this one
Any suggestions please?

I'm using Access 2007, with what I think is a normal database that I've built up over the past month (maybe 15 tables, <1000 records, 20 queries, 4 or 5 reports and macros). I'm not an experienced Access programmer, so I don't think I'm doing anything fancy with security settings or any other such stuff. (If I have, it's surely by accident, not by intent.)
When I try to back up the db using the simple office button -> manage -> backup method, access generates a date-stamped backup filename and opens a file save dialog for me, but it ALWAYS fails to backup the database. I always get the same error message when I click save, whether I save on my machine, or on a network drive.
"Could not use '<path to the current database dir><backname>.accdb; file already in use."
This same error occurs when I create a new blank database with a single Table1 in it, so I don't think it's my database.
Does anyone have any idea why this might be happening? I scoured the net for help, but nothing. I checked various Access forums, but nothing. So I arrive here after I've done my homework... thanks
I have done the mistake of not keeping a backup, what I did is split my database file access and then created my mde file, I need to change some data on my tables, but I get the msg that I cant edit a linked table, is there a way that I could put things back the way it was, also this path that was created is it possible to change for future purposes (I might have to move the dir into a different path)
Thanks.
Hi, I am not sure where to put this thread hopefully someone here can help me.
I have spent a good deal of time developing a very effective access database for a client. It is split into a front end and back end and connected using the Linked Table Manager when necessary.
The front end is quite loaded with queries, reports, forms, macros etc and the back end simply has the tables.
The front end is about 15 mb and the back about 8 mb.
Current set up is a small workgroup network with about 4 -5 consecutive users at any one given time.
I am looking for some advice on how to set up or facilitate getting the backend on the internet so anyone with a front end can access it outside of the LAN.
Today I set up an account with WebDrive which can connect to and assign a drive letter on your pc to any FTP, HTTP site.
I made the connection with WebDrive and using the linked table manager successfully linked the tables on my local machine to the back end on the FTP server - and actually ran the database at a pretty good rate.
I noticed however that it was downloading the backend to my local pc and once I closed the (a) form it was uploading the data back to the server? Very slow and often threw errors.
This of course is not what I wanted. Has anyone heard of doing this? Any work arounds or setting params would be greatly appreciated.
I have been told to create the DB in ASP but I do not have any idea on how to do that whatsoever...
Any advice or insight would be awesome!
Thanks!

I have a database already split and I wanted to put a password on the back end. When I open up the front end and try to navigate through the forms it says "Not a valid password".Is there somewhere I need to go / something I need to do to link up the two now that a password has been created?
View 4 Replies View RelatedHey guys,
How can I change the tables' splitted file path via vba?
Ex.: c: ables.mdb -> c:ew path ables.mdb
thank you.
So the database I have right now is split, with the back end on our server. Everything has been going great, however there are several second time delays when loading large forms, queries, etc. I've heard that moving the back end to an sql server is the way to go for speed.All forms and queries are on front end of database. Tables are located on the back end which is sitting on the server.

I'm about to move to a back end / front end system, from a single database file. Before I do so, I want to make sure I have all bases covered so to speak.
My back end file will reside on a server. I am aware that path names are sometimes changed by network administrators without warning.
From tests, I notice that, if the path to the back end can't be found, one cannot open the front end database file at all (Access 2003).
My question is: if my back end file gets moved, or the path changed, how can I get into my front end file to update the linked tables.
Many thanks in advance.

I am trying to create a navigation form on a split database with front end and back end.But Access is not letting me drag forms or reports into the navigation form. Why?

Why Access (2010) database is creating backup copy by itself?
View 2 Replies View RelatedI am using Access 2007 database in work environment. When one of my colleagues tried to update some records in a table, it created a backup of the database.
The issue is that the size of the actual database is much smaller than the size of the backup. However all the data are present and I don't think any data has been deleted.
But I don't know why there is a difference in size?
Some of the tables in the database are linked from MS SQL Server.
Just wanted to confirm which is the best way to create an automatic back up of a access DB. (Split DB, backing up the BE - Access2010)
Firstly I was thinking of just creating a batch file to copy the file to a new source directly with a task scheduler set up.
Ideally I'd like it to run daily and have the date of the back up added to the end of the filepath.
I have the following function that I found online. Unfortunately I can't remember where I got it since I've had it for a little while. Today, when I tried to actually put it to use it didn't work.
I'm calling it from a form as follows: CompactDB (tblHotword)
tblHotword is just a random table from the back end. My understanding of the function was that it would use that table to connect and get the file name of the back end.
Whenever I run it, Access pops up a window that says "Object required" and nothing else. It doesn't look like a standard error message popup. When I click 'OK', Access continues with the rest of the code as if nothing went wrong. The function doesn't run though.
Code:
Public Function CompactDB(TableName As String) As Boolean
On Error GoTo Err_CompactDB
Dim stFileName
DoCmd.Hourglass True
stFileName = db.TableDefs(TableName).Connect
[code]....
I plan on using Excel as the front-end and Access as the back-end only. (all queries and forms are in Excel). A single Access database will be queried from multiple Excel files that will be located on the share drive (Linux server). Access tables contain memo, text and number fields. Data will be sent to Access tables and records will be appended/deleted; all via Excel.
There will be multiple users interacting with a single Access database via multiple Excel files located on the shared drive. Users will be interacting from different workstations with Windows 7, all have Access 2010 and Excel 2010 installed.
This process works for me from my workstation but I am not sure what will happen when other 4 people will be sending/appending/deleting records to the same Database? How do I make this work? What settings do I need to check in Access to make this possible?
I have a database which is split so that several people can have a 'front end' to the database to access one common back end. This works fine on a network but I thought I could load the backend up to my webspace and then with the links manager point to it, but it doesn't work. I get an error report of 'not a valid file name.'
The website is [URL] .... and the backend database name is Probus_data_A.accdb and so I entered [URL] .... as the address in link manager.
So i want to protect the back end of a database but im limited to what I can do....I am unable to restrict members from accessing the file by username...I am unable to place it in a local area which is pass protected...I am also unable to encrypt the back end as the front end needs to be able to access it (and I dont know how to allow it to do that...)
View 2 Replies View RelatedI have created an access 07 database and split it to a back-end and a front-end with linked tables.
I wish to deploy it an a network of 4 computers, 3 of which are running on XP. The back-end will be on a computer running on XP. Now, from the instructions I have come across online, the Back-end has to be located on a folder where all users have Red and Write rights!!! And I am thinking, if the users on this network can actually see the back-end since it is on a shared folder where they have all the rights, then does that not compromise the security?
Is there a way of linking to the back-end on a network WITHOUT the users being able to access the back-end?
I need to change the password to the front end of my split database. How would I do this?
View 1 Replies View RelatedI haven't done any testing yet on splitting the database I'm working on but a question came up today about networking.
This database is going to be used by a few equipment operators to record machine readings on the manufacturing floor. There is a wireless network and we are in the process of confirming that the wireless signal reaches all the areas. The users will be using ruggedized windows tablets to enter the data.
The BE of the split database will reside on a network drive to ensure everyone that needs it will have access and it will be regularly backed up. etc.
Since there is alot of heavy machinery, there may be some spots where connectivity will be weak or non-existent while they are entering their readings.
The question is how will the runtime FE handle it if connectivity is temporarily interrupted?
