Locking Down An .mdb File
Feb 8, 2006
I have to send an access application out to some people who need to preview it's functionality. What is the best way for me to send this .mdb file to them so they can use it (tables, forms, queries, macros and functions) but still keep them from opeing up the objects and viewing the code behind them? Is there a way of sending the .mdb file out so that objects cannot be seen in design mode and the objects cannot be viewed other than through the flow of the application? As you might have already guessed, I am new at securing an .mdb file for outside use. Your help would be greatly appreciated.
Thanks!

Does anyone know how to lock a database so it can be accessed by only one person at a time? We have several users using a 'local' copy of the same database and frequently synchronizing with a network copy. We want to avoid a situation where more than one person is trying to synchronize with the master. Please advise - thanks!

How can I remove a Recording-Locking file without re-booting the computer? I've tried cut and copy and paste, with no results. No one is using the mdb file, but it has a record locking file associated with it.

I have inherited a number of 2007 Access databases that have a PDF (Adobe Acrobat Document) as the file type for the locking record.
These databases seem significantly slower, and have more frequent "Not Responding" periods on the network - especially when compared to those with a standard ldb file type locking record.
What determines the file type for a locking record?
Can the Adobe locking record be changed to a ldb? and How?

It just read in Access Help that if you have open db using record locking checked that you must open the database using the File=> Open command from the MenuBar. Does anyone know anything about this or can anyone comfirm this a s true?

Hi, I just recently split my Access db (FE/BE), copied the FE to each of the clients, and it seemed to be working fine. This morning however, two users went into the db, and the second user kept getting the error can't find the file \servernameshare_namedb_fe.mdb. Now, none of my users can launch it. How can I resolve this? Will this keep happening?

Hi,
I don't know whether you can help :D But i am in need of some code/guidence, or a way to go about trying to do what i want to achieve.
Basically, i am creating a invoice producing software in Microsoft Access, based upon Computing parts resaleing.
Because the supplier, i use changes the prices daily, when i type the products into the Parts Table, the price being typed in will change for the next customer to have the same part.
Basically because i am using this software to produce Profit and Loss, The invoice will be looking back at the Parts table, and changing the unit costs for invoices which are say weeks old.
I am wondering whether i can "lock" the invoice so it cannot be updated from the Parts list and keep the profit the same, so i get an accruate result when i come to look at it.
I will apprechaite any help or guidance.
Regards
PC_Doctor

So with the help of many of you on this site, I was able to build my first Access database. Thank you all.
Now that I'm all done, I have one final thing to figure out.
I have incorporated user authentication into the database for a minimal level of security. Everything finally works like it should, however there is one "flaw" I have found.
In "Access Options" I have the login form set to open when the DB is open, and navigation and ribbon/toolbars are deactivated so only the login form and "Home" ribbon are showing when the DB is opened.
The problem with this, is that a curious user that shouldn't have access could get access fairly easily.
If they right clicked the "Home" ribbon, then left clicked "Customize Quick Access Toolbar", they could change the default form to whatever they wanted. Thus bypassing the login form and nullifying any security that it offered. Ideally, there should be no ribbons or toolbars. I just don't know how to get rid of them.
Has anyone else run into this problem?

I have an Access Front-end that I made into an MDE file. I loaded the MDE onto a server and now there are multiple people accessing the MDE file via shortcuts on their desktop. I noticed since this update went into effect that the MDB file that the MDE file was made from is being locked when people are using the MDE file. I thought I could have made a mistake with one of the shortcuts and that a user was accessing the MDB file instead of the MDE but I had the Network Admin check and no one was in the MDB file at the time it was locked.
I'm wondering if the MDB file should be locked while a user is in the MDE file or if it's a bug?
Thanks,
Michael O'Brien

Is there any way to "lock down" newly created records somehow, so that only the person who created them can edit them after the fact?
Obviously, this would require some kind of system where everyone logged in with some kind of userID and password...and even then, I don't know how such a security system could be set up.
Is this possible? If SO, are there any examples of it anywhere that I could check out?
Thanks in advance!

is it possible once a record has been entered, to lock it so that it can not be changed by just anyone but that the administrator could change it using a password?

I have a fixed length .txt which I am linking into a MS Access 2002 d/b.
My options are set to :
default open mode -shared
default record locking - no locks
Open database using record level locking is unchecked
the (datasheet) form is set to:
allow edits/deletions/additions - no
recordset type - snapshot
record locks - no locks
the text box objects are set to:
enabled - no
locked - no
I have no requery actions associated with any events at all.
My problem is that while the form is active I am unable to open the source .txt and if it is already open I cannot save it. There is obviosuly a lock occuring on the .txt object - how can I prevent it occuring?
thanks!

I have looked on the forums and cant quite find what im looking for so i wanted to ask you lot for help.
I have a database i have created.
It will be sent out to people to populate via a series of forms i have created.
How can I lock it down so that:
1) you cant access any of the database apart from the forms
2) Lock it so no one can get in to view the code anywhere or make any amendments to the forms and database what so ever

I update the table through a form.
Each page in the form updates one complete row of the table.
I am trying to find a method to block each row of the table (or equivalenty each record in the form) after completing the entry in order to prevent unwanted deletion or alteration of the entries of this record in the future.
Is this possible?

If you have a combo-box that is limited to values in a list, how do you set it up so that the user is not able to input into the field but still able to select from the drop-down??
Is this possible, if so how?...please

I’m new to access but I have created a table with a form linked to it. It shows one record per page. I just want to be able to lock and unlock individual records in the form by using a checkbox. This will prevent me from accidently making a change to an old record.
For example, when the checkbox is unchecked. the current record on the form can still be edited. When the checkbox is checked, the record can only be viewed, not edited. I still need to be able to navigate through the locked record and create a duplicate from the locked record though. Does anyone know a simple way to do this? My guess that it has to do with the AfterUpdate event? Thanks for any help.

I have a single table app with a form. The form pretty much just displays the data that is in the table in a more user friendly view. Right now when a user enters data into the form it automatically adds it to the table. What I want is for the table to not be updated until the user clicks a Save button. Can anyone tell me how to do this?

Had a good look at previous posts but couldn't find exactly what I am after.
Having entered a record I don't want users to go back and edit/amend the input. I can see how to lock and unlock records but controlling this wilt say a checkbox also means any user can 'uncheck' and edit. Is there a method to restrict who can unlock ('uncheck') and edit a record, other than using Access Security permissions.
Thanks

I am having a problem with locking, and it is crashing our website.
I suspect it is a locking problem because everytime the database goes down, I ftp into the site and see the dreaded *.ldb file.
Access is suspose to support from 15 to 20 concurrent users, right? The log files show no more than two or three users accessing the database at the same time. By "same time" I mean within one second.
Below is the code which updates the database. Can anyone see anything wrong with this?
Also, if I wrote the information to a text file with the FileSystemObject instead to Access, would I solve the problem of locking?
BEGIN CODE -----------------
sub OpenDB(sConn)
'Opens the given connection and initializes the recordset
conn.open sConn
set rs.ActiveConnection = conn
rs.CursorType = adOpenStatic
end sub
OpenDB sConnStats
'Get ID's by Names
lIdOS = GetIdOS(sOS)
lIdColor = GetIdColor(sColor)
lIdBrowser = GetIdBrowser(sBrowser)
lIdPath = GetIdPath(sPath)
lIdRef = GetIdRef(sReferer)
lIdRes = GetIdRes(sResolution)
sSQL = "SELECT * FROM Stats"
rs.Open sSQL,,,adCmdTable
'Save the data
rs.AddNew
rs("OsID") = lIdOS
rs("ColorID") = lIdColor
rs("BrowserID") = lIdBrowser
rs("PathID") = lIdPath
rs("RefID") = lIdRef
rs("ResID") = lIdRes
rs("Date") = date
rs("Time") = time
rs("IP") = sIP
rs.Update
'Terminate database connection
CloseDB

I am new at this stuff. So please excuse my ignorance. I created a database which a lot of my colleagues want a copy. I don't mind giving them a copy. However I don't want them to change the design or copy it to give to others. I don't mind them adding their records.
Is this possible to do? Or should I just keep the database to myself.
Thanks in advance to your advice.

I am using access to connect to a ODBC Data Source which is linked to data on an SQL Server.
The problem I am having is I am using the following code, behind a button on a form, to add a new record to a table. After the code is run the record it adds is constantly locked, even after closing access. The only way I can do anything with the record is through the Enterprise Manager on the Server.
The error I get is 'The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.' I am the only person using this database.
Code: Dim Rst As New ADODB.Recordset Rst.Open "tblLeaveTemp", CurrentProject.Connection, adOpenDynamic, adLockOptimistic Rst.AddNew Rst.Fields("StaffID") = 999 Rst.Update Rst.Close Set Rst = Nothing
Sorry was not to sure which forum to post on (SQL/Access) if needs be I will repost on SQL.
Cheers
