I have a Access 2003 and lower databases. The company i work for is currently using MS Office 2007 and Access 2003 instead of Access 2007 because of issues with library references. We're currently converting the Access 2003 databases to Access 2007, but some users are already being upgraded to MS Office 2013 and Access 2013.
I am aware that Access will only change library references when design changes are made in Access 2013 which is not something we want because it will cause issues for users still using Access 2007.
My question is what constitutes a design change? For example we have some forms who's labels change based on user selection, would that be considered a design change? We do not want Access 2013 users to inadvertently make design changes.
The only way to avoid users making inadvertent changes would be to either use the Runtime instead of a full version of Access on their machine or force the database to open in Runtime mode by changing the your front-end's database extension to accdr.
Now, if your aplication relies on the standard office references, you should be ok (for most of them) as Access will use the right one for the version you have.
Any any rate, the fact that you are worried about users making inadvertent modification seems to imply that your users are sharing a front-end, which is not the recommended way to deploy an Access application: the application should be split.
Database containing the shared tables of the application remain on a network share. The Front-end, containing the UI and business code, should be deployed on the local machine of each user. The front-end only contain links to the tables in the backend.
This is a safe multi-user design since only data is shared, not the UI state.
Now if you have that design, if would not matter too much if users made accidental updates since that would only be local to their machine.
In that configuration, you can also keep sharing a specific mdb database with various front-ends for Access 2003, 2007, 2013 being deployed for different users.
Deployment is the hard part since you want that to happen automatically when there is a new version of the front-end available. There are tools like Auto FE Updater that can help.

I has a headache, my question is not pure programming question, I don't know is it belong to the Stackoverflow question. Or it belong to somewhere else such as SuperUser?
Current System :
Currently, we are using Windows XP + Access 2003, we have a database system written in Access 2003 MDB format, it separtated into 2 MDB files, one for database data, and one for front-end.
Lucky, The front-end do not contain Data Access Page. It contains:
Forms, Reports, Queries, Macros, VBA Modules.
We have not use any third party objects, all forms/report only use the default Microsoft controls, all VBA only use the default Microsoft libraries.
My headache background :
Due to the policy of my company computer support department, force all of our computer workstation to upgrade from Windows XP + Office 2003 to Windows 7 + Office 2010, they force us to upgrade because they will not support old system.
My headache :
Now I study what should I do if my system will be Windows 7 + Access 2010. I have study something by Google. Here is my summary so far:
Solution 1 : Convert the front-end MDB to ACCDB, keep the back-end MDB.
Since back-end data is important, I don't want to take risk to do conversion. I am very concern will the front-end converion safe and easy? and can I link the ACCDB to MDB(password protected)?
Solution 2 : Convert both 2 MDB to ACCDB.
Will it easy and data safe? I worry it will crash my data.
Solution 3 : Keep both 2 MDB remain MDB
I read from Microsoft site, 97 MDB cannot change design, ok my system is 2003 MDB, but I very doubtful on 2003 MDB will have problems too. Access 2010 introduce many new objects, on the others hand, maybe some 2003 objects is no longer work in 2010. I have read from Google, some people cannot save the form/report design in MDB, because 2010 silently add the new objects.
Would anyone give me suggestion and share experience?
You have the option to keep your database in mdb and run it in Access 2010. In 80% of the cases it will run well with any change. If you have issues, there is a page:

and also a utility tool to test your database:

Take a look at both and you will see how you can solve your dilemma.
I have a website online with just HTML and I am not willing to use any other programming language apart from Javascript. All I need to do is connect my Microsoft Access database on my computer to a form hosted online so when information is submitted online it is updated on MS access the next time I open the file up. Is this possible and how can it be done?
Turns out, you can do this with zero code. If you use office 365, and publish an Access web forms.
Any information entered into the Access web form will automatic appear in your local database. The synchronizing of data from the web site and pulling down of the records to a local copy works automatic and without the need to write any code. In fact the sync starts automatic when you launch the client application. (it runs in disconnected mode). And any records you enter in the client application will also sync up and appear on the web site.
So, you can use Access and write zero code, and this two way sync feature is built in.
You need Access 2010, and either SharePoint 2010 (enterprise), or you can use office 365 and the $6 per month p1 plan which also does support Access web publishing.
However, I suspect issues of user logons and security may well be a greater issue here, and thus office 365 might not be correct from a user logon point of view. You can invite up to 50 users to that site for the basic $6 per month, but all users of the site will require a logon (which can be due to being invited to the site).
There are two videos of mine here showing this setup in action here:
http://www.youtube.com/playlist?list=PL27E956A1537FE1C5&feature=plcp
I think what you are trying to do is very impractical. You'll need to use Server Side Javascript to insert your data into a database, preferably SQL Server, and then you'll have to write some kind of code to sync the SQL Server Database to your Access database.
Alternately, you could setup your Access database so it connects to the same instance of SQL Server as your website using ODBC linked tables or ADO. I cannot really recommend this, especially if the data you have in your Access database is anything you wouldn't want to be public. Also, using MS Access to access a database across the WAN/Internet is really not recommended although it can certainly be done, as long as you aren't working with large amounts of data, large quantity of records, etc.
I am not willing to use any other programming language apart from Javascript.
And why aren't you willing to use something else? I don't think you're going to get anywhere if you don't open your mind to using the right tools for the right job.
Here's something that might help you get connected to SQL from Javascript:

Is there a way to version the VBA modules inside an Access 2007 database, or am I just stuck with exporting the code and keeping it separate from the database and maintaining two different copies?
MS Access has a MSSCCI interface which you can connect to any source control system which has a MSSCCI interface. Many of them do. For example for SVN there is AgentSVN or VisualSVN.
Download and install the Access 2007 Developer Extensions, and choose the source code control from your installed SCC providers.
Source control in MS Access uses the Access SaveAsText/LoadFromText methods. All recent versions of Access use a VBA object to hold the VBA modules in, they aren't stored natively in the database anymore, so you can't just export the record holding each module as you used to be able to do.
There are mixed reports about using integrated source control in MS Access. Your milage may vary.
On a historical note, a multi-user, multi-process relational database is ideal for ensuring coherance in source code. According to some reports, the Office 2000 developers were unable to maintain project coherence when using the native database to store modules, and fixed it by using a locked single project object. Possibly missing the fact that Windows 2000 SMB server was corrupting data (fixed in Win2K SP1).
Based on the response so far, I conclude you can't have versioning.
I believe this is because an Access DB code-base is not viewed as a set of modules -- that is, not as interchangeable elements the way code is in many other settings. A truly modular approach increases the requirement for strict control because you must ensure coherence; thus, versioning.
Code in VBA is not handled as agile -- which of course is understandable historically. It's a huge watershed in development approach. So while you benefit from an agile mindset, you won't find it facilitated so well.
NOTE:
In case you're not aware, some key aspects of modular approach are met by separating the app into client and server documents (splitting your database).
I've got a MS Access database with a table and a form, but I want the user to only see the form. I don't want them to be able to edit any of the data. The user should only be able to use the form to query the table. Any suggestions??
There are a few ways to enforce some control over what users can do.
AutoExec
The most simple way is to use an AutoExec macro to initialise the user interface when the application starts.
That way to can make sure that only the form you want is displayed and hide everything else.
Runtime
A good complement to this approach is to compile your application and force the user to use the Access Runtime to use your application.
In the runtime, users don't have access to all the standard tools unless you explicitly code for it.
A good thing to know is that unlike previous versions, the Access 2007 Runtime is free, and that makes Access a very cheap platform to develop for.
Runtime emulation
With Access 2007, a simple way to ensure that the application will open as if only the runtime was installed is to change the extension of the database to .accdr.
You can also force a full Access installation to open a normal database in Runtime emulation by passing the /runtime command line switch.
Secure data-access
Note that short of encrypting the database (but then you have to manage the password), all you can do is make it hard for the user to open the tables manually.
A determined and knowledgeable user can always circumvent these protective measures and access the data.
If you need a really secure solution though, Access may not be the best choice: implementing fine grained security in Access is a greater challenge than the alternatives, say storing the data into a SQL Server database for instance where security is enforced.

Security Considerations and Guidance for Access 2007 on MSDN
A simple Microsoft Access User-Level Security Tutorial for older versions of Access.
FormSafe, a commercial product that helps enforce security on form controls.
I believe you want to use Access User-Level Security. Here's the documentation at Microsoft.
If you are using Access 2003 or earlier, you can use user level security, as mentioned. If you are using Access 2007 you are out of luck - Microsoft in their wisdom removed this ability. You will basically have to write your own login and set permissions on editing etc. using VBA code.
What are the implications of running a Microsoft Access Database in both 2003 and 2007?
Is there some class I forgot to take?
The program was originally built in office 2003, and then run in 2007. Issues seem to happen when the machine it is being run on has both 2003 and 2007 on it. The issue would also appear to stem from reference from the "Microsoft Access 12.0 Object Library" (or the "Microsoft Access 11.0 Object Library" in 2003). To see this, just look at the Tools: Refrences menu on the VBA screen.
The error's symptom is basically the code not be recognized (almost like it doesn’t recognize the programming language I’m using). It usually follows this with a box that says "The expression On Load you entered as the event property settings produced the following error: Object or class does not support the set of events". You can also replace “On Load” with “On Click” for buttons or “On Change” for text boxes.
I personally suspect that the computer is taking parts of the Microsoft Access 11.0/12.0 Object Library and then mixes the two into a useless VBA reference. What further confirms my suspicion is the box that pops up when going between the two that says "Configuring Microsoft Access" Another issue that further confirms my suspicion is it will run on whichever one it is opened on first (2007, for example) and then not run on the other (2003 continuing the example)
The only other issue is I have had to fix was changing the last part of the DoCmd.OpenForm ,,,,, acFormReadOnly (or acReadOnly, depending on how the machine seems to feel on that particular day - yes it would work with one, one day and then want me to switch it another) to simply locking the individual text boxes
Maybe it’s not quite coding, but I think it might be able to be fixed by coding.
Hopefully that’s enough for someone to come up with something.
Microsoft's official position is that installing multiple office versions on the same pc is not supported and not recommended, and Access 2007 seems to be designed to prove that to us!
That said, you can avoid most issues by doing the following:
1 - Splitting the db into a back end and front end. Place the back end (tables and relationships) in a network folder, and place a copy of the front end (all other objects) on each user's desktop.
2 - It's best to make the front end an mde to avoid the references shuffle every time you open the db in the other version of Access.
3 - Create a shortcut to open the front end with the desired version of Access so it's always opened with that version. (And remember to use the shortcut!) In the shortcut's target:
"path to Access 12 msaccess.exe" "path to db.mdb"
We have an MS-Acces application, developped with Access 2003 and used on either full or runtime version of Access 2003 and Access 2007 (Access 2007 Runtime being free, we are making a great use of it!). There is no particular issue except the references management. Our code analyses the Office version installed on the computer and automatically updates corresponding references (not only Access but also Excel, Outlook, Word, etc.: code is very tricky but of great interest!)
To my own knowledge, no major objects, properties or methods available in Office 2003/VBA were deprecated in Office 2007. Office 2003 code will then run with Access 2007 once these references issues solved. Some new objects were introduced in Office 2007 so I would not advise any developer to use it to develop code to be further used with Access 2003.
But the main & real issue of your question is: why should one run both Access versions on the same computer? This is what I'd do if I want to make sure to crash my apps. I think that if your objectives were to develop software, you should definitely find a better configuration for your machine!
In general, having multiple versions of Access installed on the one machine is unsupported and will result in the issues you are seeing with the object references.
If the database is authored in Access 2003, compiled to an .MDE, and then deployed onto a separate Windows instance running Access 2007, you should not have any significant issues (other than UI changes such as custom toolbars being thrown into the Add-Ins ribbon).
For testing on multiple versions of Access you will need some form of isolation between each version. I use multiple virtual machines to accomplish this. My primary Windows VM runnings Office 2007 and IE7 and I have a second VM which has Office 2003 and IE6 for testing.
Note that if you wish to simply use Word, Excel and Outlook 2007 with Access 2003, you can install Access 2003 first by itself and then do a custom install of Office 2007 and deselect Access 2007.
