I'd like to secure my frontend by disabling access to the linked tables, queries etc. I thought converting to .accde would do this but apparently not. Is there a way that this can be achieved?
I am aware that I can disbale the ribbons etc but they can all be turned back on using the options menu.
I'm trying to secure my database so users can't edit tables, forms, reports, queries, etc.I'm splitting the database, making an ACCDE for users:
1. I inserted code to disable the bypass key.
2. I inserted code to hide the Quick Access Toolbar (QAT) in the On_Load sub of the form that opens with the DB.
3. Deselect Navigation Pane, Allow Full Menus and Allow Default Shortcut Menus are deselected
4. Then, I use the immediate window to show the QAT, I then create an ACCDE.
How do I link this ACCDE with the original ACCDB? Am I supposed to delete tables from the front end and link the forms/reports to the back end DB?
If I have an MS Access frontend that connects to an MS Access backend, is there a way to hide/permission block the pathway to the backend's folder but still allow access via the frontend db?
Right now I can't dedicate a server to a more "secure" form of DB or anything like that so I'm stuck with MS Access for now. I just don't want someone looking at, say, a link table path and then navigating to that folder and getting access to backend information.
I have an application that is used by individual teachers to generate reports for central admin. It is not secured except I have locked out access to all objects, Navigation pane is hidden, etc to protect the integrity of the tool. I must also maintain this as changes are propagated. I am trying to find a way to upgrade forms, functions, queries, etc without manually having to unlock and relock every db for each school site when changes are required. I have tried importing and exporting from a master db, turning objects on and off by recognizing my password, splitting code and data (db's are on flash drives and path changes every time they are inserted, many teachers cannot handle refreshing table links), I have tried writing code to import the changes at next startup, etc. It is written on Access 2003.

I have just put together a small database, and have used the user-level security wizzard to set up groups so i can restrict access to the database.
I have also been through all the user and group permissions and tried to set the security up so that the data entry staff can enter data but not change any of the forms or queries.
This is where i am hitting the wall.... although i have set up this protection, when i access the database under the staff name and password I am still able to view the forms and queries in design view and change them.
Can someone plaese point out where I am going wrong
Thanks very much :)
I'm new to Access2007. I created 5 tables all related to each other in series with one-to-many joins (type 2 and all enforcements on).So an Id in table 1 can show up several times in table 2, and the same is true from tables 2 to 3, 3 to 4 and 4 to 5.I want to enter new records in such way that I can see all tables at once. I tried to do that with a query, but I can only modify records, not add new ones.I have no problem adding records to individual tables but have not figured out how to do it to this All-tables query.

Due to software licensing restrictions, my (Access 2007) development pc is NOT (may not be) connected to the network.The user pc's are all connected to the network.The network pc's only gets Access 2007 Runtime.The Front-end accde will be located at C:mydbFE heFE.accde on each user's pc.The Back-end will be located at X:mydbBE heBE.accdb (network share).
Currently (during development) the Front-end and Back-end is at C:mydbDEVFE and C:mydbDEVBE respectively - on my development pc, and the linked tables are pointing to C:mydebDEVBE.Now that I'm ready to distribute the database to the user pc's, I obviously need the Front-end's Linked Tables to point to X:mydbBE heBE.accdb
Where does Access2007 store the path to the Linked-Tables ? Is there a way I can change this path manually before making the accde ?I noticed that the path to the linked tables appear in the (hidden) MSysObjects table, but I do not want to mess with it until I know what the solution is.
This is my 2nd thread on the topic...I've searched the forums....
I have a database. It is on the shared folder on the server. I ran the security wizard and created a shortcut. On my machine it works perfectly...asks for a login, has a couple user groups etc...
When I run it off the server though, the shortcut doesn't work....refers to files on my machine?? and the database is unsecured.
Do I have to run the security wizard on every machine? Do I need to run the security wizard from the server? Or do I even need to run the security wizard at all??? My 2-day access course is failing me miserably...
How to Update ODBC linked tables on ms access?
View 5 Replies View RelatedI have a split database.(Access 2010).Three of the linked tables are Appointments, Appointments_OLD, Appointments_NEW.
I want to use vba to rename Appointments as Appointments_OLD (replacing the current one) and to rename Appointments_NEW as Appointments (replacing the current one)
I have used:
'replace Appointments_OLD by Appointments, replace Appointments by Appointments_NEW
DoCmd.Rename "Appointments_OLD", acTable, "Appointments"
DoCmd.CopyObject , "Appointments", acTable, , "Appointments_NEW"
Unfortunately this just made Appointments and Appointments_NEW clones of one another - changes in one automatically occur in the other.
What I actually want to do is to swap the names round in the backend database while maintaining the right links to the frontend.
Is this possible using vba in the frontend?
Our master database has linked tables with ODBC to our SQL database and linked tables to another access database. On the computer i'm running this from a System DSN data source has been created to connect to our SQL database.
The problem I'm having is when I run Macros to kick off Queries, there seems to be some kind of timeout issue and its not consistant. Sometimes in Access after a hour or two, the ODBC links somehow just fails. I have to go up to the menu and go to 'Get External Data' and then 'Link Tables' and relink the ODBC DSN connection. I make sure to hit save password and the end but that doesn't seem to do much. This also happens sometimes when I close and reopen the database.
But it seems erratic, sometimes it can stay up for hours but sometimes just a few mins. Sometimes I can close the Access database and reopen without losing connection. Being so erratic, this makes it very hard for me to run batch files nightly to kick off Macros. Is there some kind of inactivty timer for DSNs? Or maybe with the SQL database itself? Or is the way i'm restablishing the ODBC connection wrong ?
I have made a program in Access with linked tables from oracle (ODBC).
In access when I'm going to use that tables or when I see the records on the table all the numbers with decimals shows without separators (,).
99,99 looks like 9999.
This is a big problem because I'm working with prices.
I tried to change the NSL_Language in Regedit to:
AMERICAN_AMERICA.WE8ISO8859P1
from:
SPANISH_SPAIN.WE8MSWIN1252
AND it works ONLY in my computer, when I try to fix it and change the language doesn't work, and i don't know why.
PD: In addition, in the other PC's, some characters seems wrong like "�" that looks like a square.
I created a database a few years ago and it has been working well. This database is split.
Recently I started to update the front end based on user feedback and I am adding some queries.
I am noticing that sometimes I try to create a new query and Access tells me that the tables that are involved in the query are not related. Sure enough if I check in the front end, the table relationships are not the same as those in the back end and while the table relationships I need exist in the back end, they do not in the front end.
While the relationships were initially created in the unsplit database, it is possible that I added some of them later during past development/updating processes when the database was already split. This is the only reason I can think of for them to be different.
When I add a relationship in the back end (new table or bug fix) do I also need to add it to the front end if the database is split? if not, why would they be different? What kind of issues can this create?
I am new'ish to access, although we have had an SQL server 2000 backend for some time, it has purely been used for our MIS systems, now I want to develop using Access 2003 as the front end, and SQL as the backend, however, I don't know the most effective way to link to the data on SQL, I can use either linked tables through Access, or not use linked tables and just send SQL queries to the server using vba code, I am not sure which would be the best solution to creating a new application.
Any ideas whether I should use linked tables or fire off vba SQL queries ?
cheers

I have built a database and within it my queries I use for reporting make tables in a separate database. This allows me to work in my data base and update info as needed. My problem is that my make table queries wont run if anyone has one of the report pivot tables open. I have added macros to all the Excel files that pull from the reporting DB but I still have several times when I cannot update because someone is using the pivot table, Is there a way to allow me to update the report DB's while the pivot tables are open? I have tried using manual refresh methods and disabling auto update on open but the result is the same.
View 2 Replies View RelatedI have set up a table (A) that is linked to another table(B) in my database. This linked table (A) is then used in a number of queries. When the data in the original table (A) is updated it does update the data in the linked table (B) as it should. However, when I run the queries they do not bring up any records. It seems that they are not looking at an updated version of the linked table (A) because if I rebuild the query it finds the records as it should. Any advice on this would be very gratefully received.
View 1 Replies View RelatedI have a split db with tables in the back end and my forms, reports, code etc. in the front end.
I encrypted the back end with a password. That worked fine.
I deleted and relinked my tables to the encrypted back end. That worked fine as well.
I have a function that will disable the shift key bypass. If I run that in my front end db then I can't save it as an accde because I can't get to the HOME screen. If I save it as an accde first then I can't run my 'disable shift key bypass' function because I can't get to the modules!
How can I secure a split Access 2010 database so that the user cannot execute shift bypass on the front end or make any changes to the code?

View 4 Replies View RelatedI have two linked tables (Unique_ID)
Table1 has a record of unique tasks.
Table2 has a list of people to do those tasks
They are linked by a Unique_ID (one to many - Table1 to Table2).Sometimes there can be an instance where there are Unique_ID's in Table2 but the reference Unique_ID is missing from Table1.
I have a select query that can show me these like so.
table2 table1
Unique_ID Unique_ID
Like * Not Like *
I can open the query and simply delete the records fine however i wish to automate this.What I want to do is delete the unrefenced Unique_ID's from table2.I have tried to just convert this select query into a delete query but it asks me which table I wish to delete and I cannot see where to enter this information.
Hi,
This may be a simple question, but I'd like to reassure myself, so here goes. I have a database which is used to produce a pile of reports, and the tables are linked to a second database. I now need to update the reports, and add new data for this year. But the second database is password protected, and yep, I don't know that password. (I'm taking over this project from someone who left 3 years ago - I haven't just forgotten the password honest!)
Is it ok to import new data to the second database, and still carry on producing reports?
What if I want to change the properties in one of my linked tables? Can I delete the link, change the property, and then reapply the link?
Thanks for your advice,
Antro.
Hi, There seem to be a serious bug in Access 97, and I want to know if anyone has encountered this before.
I tried to describe the problem as best as I can, I also included a flash video to describe everything, here it is:
http://naderchehab.googlepages.com/linkedtablebug.swf (~1 MB)
My database has two tables:
- dbo_InventoryLocation which is linking to SQL Server 2000 via ODBC which contains inventory quantities for each product, and
- tblPRODUCTS_BUSINESS which is linking to another access database on the network and contains product information
(item number, title, description, and a field called "InvCategory" which describes item categories). I wrote a very simple query that links these two tables together:
SELECT tblPRODUCTS_BUSINESS.InvCategory, dbo_InventoryLocation.ItemNumber
FROM tblPRODUCTS_BUSINESS INNER JOIN dbo_InventoryLocation
ON tblPRODUCTS_BUSINESS.Item_Number = dbo_InventoryLocation.ItemNumber
GROUP BY tblPRODUCTS_BUSINESS.InvCategory, dbo_InventoryLocation.ItemNumber
ORDER BY tblPRODUCTS_BUSINESS.InvCategory;
The query really doesn't matter, it's just a test. Now here's the weird part:
when I execute this query, and I scroll down to a specific category and count the number of items in that category, I see about 50 of them.
But if I specify that category as a criteria, I see more than 200!
I also noticed that this problem does not happen when I use non-linked tables.
I hope anyone has an idea what that problem might be, and I hope there is a way around it.
Thanks,
Nader

View 3 Replies View RelatedHi all,
I have been building an access database at work which would be useful to share with eveyone else at over the network or live server.
Is there a front end I can get for it, or is using the access file itself the only alternative. All i know is html, css and actionscript - so I don't think I can use this. It would have to be pretty basic - I have no idea what kind of technologies are available for me in this regard.
Any suggestions or methods would be very much appreciated!
Cheers,
Doug

The two table linked by the [type]
I need a query expression like: SlowWay: IIf([TableB].[ID]= 'T1' AND [TableB].[ID]= 'T2',[TableA].[Count])
FastWay: IIf([TableB].[ID]= 'T3' AND [TableB].[ID]= 'T4' AND [TableB].[ID]= 'T5',[TableA].[Count])
My expression keep gives me the error.
