I'd like a code to lock a table in my access database so that it can not be mistakingly deleted by the user.
It's a very basic database program i am using for basic reporting purpose. I'd like to lock the master table from the user. How can i achieve this? Any ideas?
Is it possible to lock a table/macros/forms/reports in MS Access?
View 3 Replies View RelatedIn a Access 2003 database, I have an "Inscriptions" (subscription) database with a primary key on 2 fields idPersonnel (employee) and idSession. I have made a form so that user can select a session (in a listbox), then one or more employee (another listbox) and suscribe them to that session by using a button, which, on VBA side, first check that there is enough room on the session (defined by "MaxParticipants" field on "Sessions" table, linked to "Inscriptions" table on idSession), then insert data in "Inscriptions" table
This is working fine in a single-user environnement, but fails if 2 people want to join some employees on the same session at the same time, as I have a confirmation message between check and insertion. Therefore 2 users can select employees, get the confirmation message (at this point both are told there is enough room), resulting in having more people than expected joined to the session. Fortuneatly, if both users try to insert the same employee(s) to that table, one will get a duplicate error, but insertion will be made if employees are different.
On another DB engine, such as SQL server, I would use a stored procedure that would lock the table, do the check and the insertion then unlock the table.
But it does not seem to be possible in MS Access. What are the possibilities in MS Access to prevent a session from having more than maximum number of participants ?
I need to lock and unlock a a few text fields with a CMd Button.
and i do know about the allowedits thing, but i only need to apply this to a few fields on my form.
can some one throw me a clue?
I want to lock a table to disallow further records.
I want to have only one record (I would have created this rec by myself) to store initial conditions and infos such Username/company etc.
Any ideas?
I'm also interesting in other solutions than locking a table if sucj a thing is not possible or nt functional.
Tnx in advance
I'm working on a database that calls on a table of zipcodes. All of these zipcodes have latitudes and longitudes connected to them..... I've searched around but cant seem to find anything on locking a table. Is it possible to lock down a table so changes cannot be made?.....(until I need to make them)

how to lock access DB Tables ,Queries, Report so other's can not import them to other access database (without encrypting my database with password ).I've noticed when forms have VBA codes it cant be imported if they locked by password(VBA) !
View 7 Replies View RelatedI am trying to define a relationship between tables. The relationship is one-to-many with forcing referential integrity. When I try to define it, I get the dabaase engine error:
"The database engine couldn't lock the table, because it is already in use by another person or process"
I am sure that the database is not opened by anyone else, it is 100% local, no other instance of Access is running, and there was no *.ldb file... What can be the problem?
Hello all,
I have a question, I'm building a MS ACCESS database and within it i have a table for putting in my program critical parameters. I don't want anyone to change the content of that table. That means not editing the 1 record in it and not adding a new record. Within the program is't a problem but if you make an other blanc database you can import the table, change it and export it back into the program (i know it is far looking but it happens).
How can i lock a table so it cannot change or it cannot be exported or imported???
Is there anyway to lock specific records in a table so users cannot edit them after a manager has approved them?
View 7 Replies View RelatedIs there a simple way that I can lock a table or better yet configure it as view only. The table is used to populate a combo box in an entry form, and I do not want anyone to have the ability to add records to the table (options in the entry form), but I would like them to be able to view the table. I don't need a robust solution with passwords. I would imagine there is a simple preference to set, I am just not seeing it.
View 1 Replies View RelatedI have a sales call tracking program.a list of available numbers are displayed to multiple users running the a user clicks on a record to get a call screen displayed with client info they then call the client and try for a sale.
the problem exists that two users can click on the same list record and open up the same call screen - they then both try to call the customer manually on the phone. one agent will get through the other will get a busy signal and record the call as a Busy Call. When the user with the customer is done he tries to record a Sale or No Sale and is met with an error message saying the record has been modified and they cannot save changes!!
I need a way to get access to immediately lock the record when it is clicked so only one person can open the call details screen? What is the best way to lock the records?
I have a form with a combo box that contains a list of customers. Select a customer from the combo box and the form fields populate with general customer info. The form has a subform on it with a combo box where you can select products. Select a product from the combo box and the subform populates with customer-specific product info.
If I open the main form and select a customer, then without doing anything else I select another customer, everything works ok. It’s when I select a product on the subform, and then try to select a different customer on the main form that I get “Run-time error 3211: The database engine could not lock table tblCustomer because it is in use by another person or process.”
Can anybody shed some light on this? I’ve been confounded by it for days.
I am having a problem running a make table query which is based on the same tables that I am using in a sub form.
Basically, the user selects certain records in the subform (which is in datasheet mode) using a check box, then once selected he hits a command button where there is some code that will run the make table query, which I use to filter other tables in a related reports.
However I keep getting this silly "database engine could not lock table" message relating to the sub form name. The subform is not linked to any records in the main form as the main form is unbound.
The solutions offered by putting DoEvents or Me.refresh/Me.requrey in the code do not work.
I have a field that generates a date from when the first input is put into another field.

I have a live db running on a VPN network (FE/BE both centrally located on a main server , users 'view' their own personal front end through the VPN tunnel) ) and have recently provided a new updateto the FE. Until this time , most users were problem free but one persisted in getting the above error message. Now the new update is in place , they all get it, and this is when no one else is using the db and a single user logs in and tries to use the system. I guess it must be an internal fault ( ie my fault ) but then why does it work for some and not for others?. It also works no problem on my system at home. The user runs Access 2000 and the db was developed in 2003 ( default file format 2000)
Any help most appreciated
Thanks in advance.
I've added a list box to my form that displays a table. This table is completely independent and gains it's data from an Append query. There is also a Delete query, which clears the table for a new set of data, and an Alter query which resets an AutoNumber column in the table (so that new data sets always start numbered at 1).
Here's the problem: Since I've added the listbox and set the RowSource to the table, whenever I run the Append query I receive the error: "The database engine could not lock table 'tblLineSheet' because it is already in use by another person or process." I've made sure to close the table, but to no avail I still get this error. Without the List Box I don't encounter this error.
I have an Access DB shared through a network folder. It is currently frozen and showing a record lock, however, none of the users have it open. Is there a way to kill the lock so I can restore it?
View 5 Replies View RelatedI have a DB with multiple import processes to take in information and populate various tables. This has been in place for some time and works with no issue.
The import process involves the creation of a local staging table, to which I import the received data, normalise it according to my own table structure, remove any duplication (i.e. same data imported repeatedly) and append the cleansed data to the main tables.
I've just added a validation step to check for data integrity. In other words, for duplicate data, rather than simply purge it as I was doing previously, I now check to see if the data has changed in any way and prompt the user if necessary (with the option to either ignore the change or update the existing record)
However, since I added this extra step, I am getting the following error message during my import process :
Error 3211 : The database engine could not lock table 'tblStaging' because it is already in use by another person or process
It only appears a) when a data change is detected and b) when the option to update is chosen, and seems to occur after the update has taken place (i.e. I can see the records suitably updated)
But I can't replicate the error while debugging so it seems to be a run-time issue. It's definitely not another user as the staging table is deliberately local (specific to that user's front-end)
I suspect I can probably solve the problem by adding some kind of DoEvents call or brief pause somewhere but the problem is, I don't know where the problem is occuring, so I don't know where to add the line? Or if that would even solve the problem at all?
Is there an easy function I can call to check if the staging table is locked? Which I could then use to debug and identify exactly where the lock is causing a problem? Or even apply the DoEvents to release the lock? (It must eventually get released as if I step through the code, I don't get the error?)
I have a form that allows a user to complete a stock take. I would like to stop other users from receiving or despatching stock while a stock take is in progress.
Is there a way I can lock a table, or stop users adding or altering records that match certain criteria. i.e. don't let users receive or despatch stock from with a locationID of 'A'.
I want to "lock" a record in a table so that it is read only and cannot be accessed/edited/deleted. Is it possible to lock a single record in this way on a permanent basis? It's actually the first record in the table.
View 5 Replies View RelatedI have a form that contains a subform. The subform is a datasheet which calls the results of a query of 4 tables (tbl_companies, tbl_deals, tbl_products, tbl_vl).
In the main form there is a button which opens a report with a historical record of dates of value changes of each product up to a chosen date. This chosen date is determined by inputting a date into a text box.
This report also sources (tbl_companies, tbl_deals, tbl_products, tbl_vl).
When I try to open the report, I get the run-time error "3211".
'The database engine could not lock the table "Tbl_companies" because its already in use by another person or process.'
I'm guessing that because the query for the subform is already calling the table, the query for the report can't call the table at the same time?

I want to lock the field2 except the ID=3
Please let me know, thanks.
My company has asked for an issue tracking database with the requirements that if is someone is edditing records it locks that block down until that user is done. I don't have any idea how to do it. my db is set up this way.
tables
tblPolls
tblIssues
Querries
qryPolls
qryIssues
qryFindPollsByID
qryFindPollsbyName
Forms
FrmFindPolls
FrmSearchResultsbyId
FrmSearchResultsbyName
FrmIssueTrackingMain
FrmIssueTrackingSub
The Form Issue Tracking Main has the Sub form IssueTracking Sub
Here users enter the issues in the sub form. The forms are linked by Poll ID
Is there a way to lock all the records with the same pollid in the tbltblIssues. Also to check who is editing them at the time?
