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?

I have a call tracking database with 5 active users. Ocasionally the database will freeze, usually for several people at once. It will say:
"Can not update record; Currently Locked"
The only way to fix it is to close and re-open. I split the database, compiled it and then created an MDE file to distribute. They are using copies of the front-end, not links. The database locking more and more every day. But we are using it more. After parusing the forum I'm starting to suspect that this is a problem of "Primary Key duplication" If everyone trys to create a record at the same time, would the database lock because we all created the same record at the same time?
If so, how do I get around this? Use something other than Autonumber for the primary key? Or is this an entirely different problem?
By the way, my record locks are set to "No Locks"
Thanks!
I have designed a database which I intend to split for multi-users to access from one front end icon on a shared folder at work. I have designed a form bound to cmr record table and on it a subform to another table where cmrs activities will be saved. The form has buttons to and blank controls.
User can create a new activity entry by typing into the blank controls and pressing the save button which saves to the activity table. the edit button extracts a selected records details (selected on the subform) from the activity table and populates the blank field for a user to edit and then hit save to save changes. The delete button deletes a selected record from the activity table. I intend to have multi-users either accessing, viewing and a possibly editing the same customer at the same time. The simultaneous viewing is essential but the simultaneous editing, though not desired is inevitably going to occur.
What I would like to know is:
1. Can you lock an individual record in a table or does the whole table have to be locked. E.g If Colleague 1 is editing Cmr A's record in Table1 can he lock it so Colleague 2 can view and edit Cmr B's record in Table1
2.Can Colleague 1 access/read Cmr A's record in Table1 to retrieve details toe the form controls if Colleague 2 is viewing or editing Cmr A's record in Table1
3. If record lock is possible, how can I initiate it in my example code below.Edit activity record Code
Code:
Private Sub Edit_A_Click()
'Get Data to text box control
With Me.R_P_Data_P_Subfrm.Form
Me.txtrID = !rID
Me.txtrID.Tag = !rID
Me.txtrefNo = !refNo
Me.cmbrpc = !rPC
[code]....
I have a company wanting to asses my database and i am willing to show them but i need to be able to lock the database so that they can view it but cannot edit anything in it either adding deleting or plan editing. How can i do this.

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!
Hello Everyone,
I just migrated a back end to a network server. Now when more than one tries to use the database they get a file in use error.
Any ides?
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

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?
How Can You Lock Table Or Form So Nobody Can Accidently Delete It Or Alter It Unless Person With Permission?
View 1 Replies View RelatedHello,
As my username states, I am a rookie to MS Access. I built a database using Access 2002, I will distributed it to other people, I will like to lock changes to certain areas such as forms, design view, etc.
Can this be done? The help is greatly appreciated!

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,

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?
View 6 Replies View RelatedI have a fixed length .txt which I am linking into a MS Access 2002 d/b.
My options are set to :

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
Cheers
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?
View 4 Replies View RelatedHad 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

anyone know about this? i've messed with it, but i think i screwed it up. when one user is using a record and another tries to access it, my program shuts down completely.
View 1 Replies View RelatedI 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.

Hi everyone,
I have a form on which I am unable to enter data. My feeling
is that it is because the recordset is locked (the text areas
are not locked).
Here's the background info:
I have 3 forms and tables that work off of one another.
CustomerInfo
SystemRecord
ServiceHistory
A CustomerInfo record must exist in order to add a SystemRecord record, and both must exist in order to add a Service History record.
Here's the example.
I had a ServiceRecord record and I click on the button to
open the ServiceHistory form to add a record. Since no
record exists, I want the 4 key fields to have values from the ServiceRecord table. So after many tries, this is the
code I came up with:
Private Sub Form_Open(Cancel As Integer)
If IsNull(Me.txtSystemID) Or IsNull(Me.txtCompanyName) Then
Set Conn = CurrentProject.Connection
Set rst = Nothing
rst.Open "ServiceHistory", Conn, adOpenKeyset, adLockOptimistic
rst.AddNew
rst!SrvSystemID = Forms!frmSystemInfo.SysSystemID
rst!SrvCompanyName = Forms!frmSystemInfo.SysCompanyName
rst!SrvSerialNumber = Forms!frmSystemInfo.SysSerialNumber
rst!SrvSystemModel = Forms!frmSystemInfo.SysSystemModel
rst.Update
rst.Save
rst.Close
Me.RecordSource = "qrySystemInfoandSrvHistory"
Else
Me.RecordSource = "qrySystemInfoandSrvHistory"
End If
End Sub
The form opens and all four fields are populated as wanted.
The problem is that all the text fields are then locked. I
tried removing the rst.Close, but that didn't work. I have
a feeling I still have a lock on the record, but don't know how
to get around it. Any ideas?
Thanks as always,

I can't do nothing in my database because it keeps saying users have it open. There is nobody in the database though. I open up the file and saw two admins names and I deleted them both because we out of the database. The database is on a network drive and when I try to do any updates I get the message "Can't save changes or make changes because the database is open"
I DON"T KNOW WHAT TO DO, FOR THE LOVE OF GOD SOMEONE HELP ME PLEASE, Help me Jesus, Help Me Oprah, Help Me Tom Cruise!
