How can you stop people editing the data in the backend database from the linked table in the front end?
The back end is passworded but you can still change data manually from the front end.
Can this be stopped?
I have been given the responsibility for a database that resides on a company network. The Database has been created by using Access 2000 in Windows XP. There are windows folders fro each team that needs use of the database and within these folders is a macro that loads the form for each team. There is a shortcut folder to the Admin Entrance point wher the actual database and tables_be are located. I have looked at both the properties of both these files and both are Access 2000 databases?
The Database called Database( not my choice of name ) contains all the forms, queries, reports,modules etc and the tables are linked to what seems to be the Admin Entrance point. Unfortunately I am unable to see the full link when using linked table manager. This I presume is the tables located in tables_be. The database table_be contains all the tables.
When trying to store the Autonumbering to the database after corruption using a solution kindly supplied by Pat Hartmann by taking a copy of both the database and table_be and working on these I successfully got the autonumbering working.
What do I need to do to successfully implemting these on the network. I have tried to copy the new files back to the network with the same names and in the same location but am getting error messages when I try access some of the forms.
Unfortuately there is no documentation as to how this database has been constructed hence the long winded post.
I have a front end and back end database
I have broken the links between the 2 databases
how can I close the backend database using VB from code in the front end database?
I keep getting errors that the DB is not exclusive
Hi - I have a front end database that is linked to 2 backend databases. I'd like to add code so that after the splashscreen pops up it checks to see if the front end is linked. If not then asks the user to enter the path for the two backend databases. I need your HELP!!1

A client has had a database in operation for about a year. They requested some updates. I have been trying to figure out an easy way to update table structer with out having the client go into the backend and add a field or two.
I wrote an update program, that copies the table from their backend, and copied it to the updated table and tried to copy it back to thier backend, but since it is in a relationship, it won't let me.
Any suggestions?

how can I close the backend database using VB from code in the front end database?
Hey guys... I created a reaaaally simple wages calculation program some time ago in VB6. When you click the save button, the records are saved to a .txt file stored in the same directoy as the program itself.
However, I'd like to take this a step further and connect this program with some tables setup in an Access database. I know this has something to do with ADO, right? But not quite sure how to set this up..
Would it be possible to get some guidance on this? If you'd like to see the program, let me know.
Thanks for any input!
Hi :)
(A2K format, but running on XP, etc)
I have used Microsoft’s Security FAQ and recommendations on this forum and build a split database; secured with one worgroup file for development and one for customers: what is the most appropriate way to upgrade the backend database content (tables mostly) (as the front-end database can just be replaced) at the customers site?
At the customer there is no development workgroup file, so no permissions to change database objects. I would really like to run sql updates from the new FE database. The solution I currently have devised to go around this problem, involves a lot of manual data moving code, to take care of referential integrity etc. However this approach has a higher risk of creating errors and also takes a lot longer time.
Is there something I have misunderstood of the Security FAQ or recommendation on this forum?
Thanx

I've created a database to track my client information. I've split it into front end and back end databases. Everything there works fine so far.
I have other co-workers who track their own clients who I will be giving this database to. So we will soon have the same database with completely different data stored in them.
If I want to make changes in the future, I should easily be able to change the front end, get them a copy to install, and all should be well.
But what if I want to make changes to the backend? Like if I decide I want to track some completely new data in a separate table on the backend. I won't have the ability to just go out to the central server and change 1 backend database. There may be 10 identically structured backends on 10 different machines that all need the new table added to them, without effecting their unique data in the existing tables.
So, assuming my explaination made sense, is there a way to make backend changes like I'll need to? Or would I have to go to each backend database and manually make the changes?
Hallo everybody
I have an Access databse in which I have devided the tables into backend and frontend by using the Database Splitter wizard.
Then if I create any tables in the frontend Access file then thease tables are visible only in the front end of this system , not from other systems if I put the back end in network.
its ok for some tables , but now I have a table which I have to put in the shared backend , but if I cerate in the front end it is visible only in front end and if I create in backend it is visible only in backend.
how to send a table in the front end to backend after database splitting is over, so that I can access this table from other systems.
if it is possible please help me.
Thank you.

Hi people,
Does anyone knows the difference between frontend and backend database? I look 4ward to hearing from any database expert.

I have a database stored out on a shared drive at my company that multiple users connect to via a front end application that they save on their own hard drives. Recently I have noticed that the back end database keeps getting opened exclusively which prevents other users from being able to access the back-end database. For the life of me I cannot figure out what about the front end opens the back end exclusively and cannot find any plausible solutions I thought I could develop something that could force close a back-end database or disconnect all users from it?
View 3 Replies View RelatedI recently added a field to one of the tables in my database. How can I transfer my existing data to the newly restructured backend?
Only 1 table has been changed to add a single new field.
I have got an complete Access database with an "Autorun" from a company.
I need to change a report definition in this database.
Wher can I find such a utility that let me open the database in the Database-window, so that I can edit reports and queries in the database?
It is an Access 2000 database I think.
Hi
We have recently upgraded our computers and therefore reinstalled Office on the new machines. The opreating system is Win XP + patch 2. The version of MS Access is 2002
For all our databases I have chosen to hide the database window, so other user don't accedentally change tables and queries etc. Now the problem is, with the new computers, whenever I minize the database and then open it, the database weindow pops up right on top of every thing else automatically.
I have no idea why this happens and how to stop it. Could any one please shed some light. Your help would be apprecialted.

Hello all,
I have a back end database that i cannot access at the moment. Is it possible to set the link of the tables for the front end application based on the location that the database will be even though i can't see that location now?
Thank you in advance.
I'd like to to import some large oracle tables from a remote server using "DoCmd.TransferDatabase..." on a daily basis. Currently, the system works, but my database is getting quite large (800 Mb) and I'd like to split off the tables to a back end database.
Is there a way to import directly to the back end database? The postings that I've seen seem to imply that one must first import the tables into my front end, then export them into the back end. Does that sound correct?
I'm at home right now, but will give it a try when I get to work. It just seems like there's got to be a more direct way!

I have a Ms Access split database where in the backend database grows up very fast and needs to be compressed everyday. I have written a batch script to compact the same and have scheduled it to be run every night. But the script is unable to compress the backend every time since the users tend to leave the application open at the end of the day. Ideally i am looking for a command line script to forcefully close the back end database if open before attempting to compact it.
I searched on web but could not find a command line script for forcefully closing the back end database.
I have many forms in my database, three of which completely freeze the database if I edit the slightest thing on them. These forms are all the same, and are unique to any other type of form in my database.
An example of one of the forms is the following:
The form is an "Edit Record" form which allows the user to edit a record directly from a form without going into the table. It is only possible to bring up the edit form by going to the main navigation form that consists of various buttons which a user would press, in this case the user would press the "Edit Record" button. This brings up a unique search form that allows a user to search for a record to edit. The user types their search parameter into the form and once the "search" button is pressed it will bring up the record with all the details in a different form.
Note - The search form is linked to the table where the edit record form is linked to a query.
My problem is this:
I have three buttons on the form; Exit, Cancel & Finish Editing.
All I wanted to do was to ammend the code of the buttons so that "Finish Editing" wouldn't close the form onced pressed and that "Cancel" would simply undo the actions of the user instead of undo and then close the form.
I know exactly how to do the ammendments. But, once completed if you return to the main navigation and click on the "edit" button the search form appears and allows you to type in the search parameters, but once the "Search" button is clicked the search form closes and you are returned to the main navigation where you are unable to click anything in access or even close the programme.
I have an access database which was created in 2003. I opened a blank database and imported the definition and data in access 2010 and made the file an accde file. Now this file has a lock symbol next to the access symbol. I am also unable to edit the main form.
View 7 Replies View RelatedI have included some code to disable the access PassKey (holding shift down as you open the database so that the database window appears). It is password protected and it works pretty well for normal users.
However, I have realised that even in this restricted mode you can go to File-Options-Current database and enable Access Keys. This then lets you open the database window by pressing F12.
My question is, is there a way to absolutely stop anyone from ever viewing the database window at all? All my code is password protected, but I still don't want an ICT person fiddling with my tables and queries!
I have an Access DB with a form that allows the user to select a new backend database. I can connect to the backend and then .refreshlinks but nothing on the form is updated. I have tried requiring the form but that doesn't do anything. I've tried loads of other things, refresh, recalc etc., but nothing updates the open form.
The only way I have managed to get it to work is to close the form and reopen it, then it shows the data from the newly linked backend database.
While it works, it doesn't look good but also there seems to be some problem with it because eventually it reports an error saying "cannot open any more databases" and when clicking OK comes back with "An error occurred while sending data to the OLE server (the application used to create the object" and a whole bunch of other messages.
I think it might have something to do with the fact that the form has a number of MS graphs open on it, but I'm not sure. Also, I can't track down a particular line of VBA code which causes this error.
how to update a form after changing the backend database.
I have a client that is using a split database. I am working on an update to the program and need to transfer a table to the backend that has the correct structure and information included in it. My thoughts are to make a one time use program that transfers the table to the backend. I have seen DoCmd.TransferDatabase and DoCmd.CopyObject as possible ways to go.

View 4 Replies View RelatedIn my form I have a subform, which displays A, B, C. Then information C is displayed in textbox. User should have a possibility to modify this data in order to modify data in database.
I am able to display information C in text box based on this subform. However it is uneditable, although property of enabled is yes and locked is no.
It seems to me, that it is impossible to edit data because it is taken not directly from database but from sub form, so I make special query which takes data directly from database however I lose an event which is based on selecting proper record from subform (there is only onEnter and onExit events)
I've got a database, which has been working fine for the last 6 months, it's nt spectacularly large, or complex (abotu 10mb, 15 tables, (5 of which are lookups), about 20 forms, 40 reports, and 30 or so queries).
I've tried to add a new query today, again nothing special:
all comes from one table:
column 1 - group by
column 2 - max
column 3 - if = "No"
column 4 is an expression: iif (a=1,col_a,iif(a=2,col_b,iif(a=3,col_c, .... ))) and so on for 8 col_*'s
The query creates happily enough, and is viewable.
When I try to save it, access shuts down completely with no warnings.
creating the query apart from the last column, saving it then works, but on adding the final column the database shuts down every time.
any ideas? I'm at a loss on this.
Cheers
