I wrote a function in visual basic which I can use in any query or form of given access database by adding the module. What I want is to able to use the function in all the databases in my machine.
A simple solution is to copy the module everytime to the database, but is there any simple solution?
In excel you can do this by adding the function to a .xla file and then copying the file to XLSTART folder. But MSACCESS doesn't have any such equivalent folder.
Can someone suggest something?
Here is a complete tutorial: Using a centralized VBA module in multiple Access databases
Make your "helper" database. Put a few procedures in there.
In your 'client' databases, open the VBA Editor
Go to Tools->References. Browse and select your helper database.
Done! You can now use all the functions in your helper database
throughout your client databases.
[EDIT]
There's no way (and it's really unnecessary) to create database which automatically starts with MS Access application.
I think that you're looking for a way to create template database which contains the set of custom objects, such as tables, vba module(s), forms, queries, etc.

I have an access database that I have been using for a while. I have been meaning to split the database for a while but hesitant to. I have many forms that link to tables. VBA code that aid in the forms and creating reports from this access database. Sometimes the VBA code will have a dynamic query that changes on certain conditions and runs a DoCmd.RunSQL.
If I split the database will all my VBA code break down as it points to the tables within my database. Do they need to be pointed to the backend or pointing towards the linked table is enough. Will the split handle this by itself?
Let me know If I was clear enough. My main concern is my forms/VBA code will stop working.
Make a backup, go to meny Database Tools, locate the Split database wizard.
Run this, and you are done.
We have a large number of access databases that contain a number of common functions. We need to make a small change to one of the functions, and are looking for a way to automate this via scripting, etc. Is there any way to get at the VBA code inside an Access database, and make a change to it?
I have used ADOX before from PS or VBS to be able to list tables, views and queries, but it does not expose the VBA code in its API.

If the code changes are always in a module with a consistent name then you can simply remove the existing module and reimport the new version in all the projects you need to apply the change.
http://www.cpearson.com/excel/VBE.aspx
The above link posts information on how to import modules into a VBA project. So simple case of looping through your multiple databases and removing the module and importing the latest version.
If the code changes are located in different module names, you can open each database and loop through the modules to search for the string. The functions you'll need are listed here (depending on the style of change, it'll most likely be some combination of Find and ReplaceLine)

So I'm moving from MS Access to MySQL:
In MS Access you can store certain INSERT, DELETE, and UPDATE queries as objects alongside your tables. Thus for anyone who don't understand computers that well, they can click on the objects and automatically run the queries to alter the master table for various business functions.
In MySQL, where and how do you store these queries, I seem to be only able to make tables. When I write a piece of code using the SQL editor, I can only save it to a remote location (such as my local desktop) and not onto the MySQL database, where it's accessible for my coworkers.
If you can't save it onto the server, how would I write a piece of code and execute it within the database that would be easily usable by others.
Thanks
The answer to this question is going to depend on your environment, your users, and your bandwidth to support any given solution. You are gaining a lot by making the switch from Access to MySQL, however you are losing some of the the WYSIWYG features. (e.g., Access forms that can bind directly to your data source.)
There are many approaches:
If your users are more advanced, simply having access to the database using MySQL Workbench may suffice. From there they would have access to run views, stored procedures, or to create their own custom queries.
Another option would be to script your objects using Python and provide a simple gui using TkInter. Python is generally thought of as an easy to use language; with built in suppport for MySQL and TkInter is its "default" interface.
Using the LAMP architecture is another largely popular paradigm using MySQL as the backend database.
There is also nothing stopping you from using Access to link to your MySQL db using MySQL as an external data source.
I hope this provides enough info to help you begin whittling down your options.
Hey guys I've written a little module/macro that helps our inventory department, they will need to run the module/macro a few times every month. They receive the databases from out in the field these are exported from some 3rd party inventory tracking system we have.
My question, is there any way to install this module/macro outside of the db file but still within access so that the inventory management team does not have to open vb editor, import the module, create a new macro, name it, set it up properly to execute the function?
The module/macro does not need to be changed for any new database that comes in.
Basically they need to be able to open any database received by the field and have this functionality in the module/macro available to them without having to set this. Is this possible?
You could look at my article for vb123.com:
Using Database Library Files in Your Access Application
The thinking there is that you can put access objects in a library file (still an mdb or mde file, or any of the new access file types) and then by just adding a reference to the file in your VBE project, you get that functionality made available to you.
It works with forms, reports, queries, classes, etc. To be honest, I haven't tried it with macros, but don't see a reason why it wouldn't work.
The beauty is that reusable functionality is packaged into one file, that is still just a plain old access file.
If you had the inclination, you could also write an access add in that basically calls your macro in the library.
We did this with a product for making dealing with SQL much easier in Access, and it has worked for years with Access installations all over the world. You can install the add in using a professional installation package such as wise installation, making it a pretty seamless experience for the end user of your macro. However, there is a considerable overhead in writing this kind of setup in a professional way. Depends on what your users need, I suppose.
Perhaps you are thinking of VBScript or a back-end, front-end set up?
You can use VBScript to perform actions on an Access database, through the Access object, with ADO and so on. The script can either accept command line input, request information, or run against any database in the current directory.
With back-end front-end, the new database becomes the back-end and the Access file with your macro is the front-end. Your macro should ask the user for the name of the back-end file and either use that with the Access object or link the tables, according to what is needed to be done.
I have a database (mdb file) that I am currently busy with. I would like to know if it is possible to generate MySQL code that would be used to create this database?
There are a couple of tools you can look at to try to do the conversion.
DataPump
Microsoft DTS (Nos Called SQL Server Integration Services)
Other option might be generate MySQL code from Access' DB MetaData you can access from JDBC, ODBC, ADO.NET or any other database access technology with metadata support. For this option you need to generate a piece of code (script). So it will only make sense if your access DataBase has a lot of table with a lot of columns or if you are planning to do this task several times.
Of course, using one of the mentioned tools will be faster if it works.
You can certainly write DDL to create and populate a MySQL database from the work that you've already done on Microsoft Access. Just put it in a text file that you execute using MySQL batch and you're all set.
If you intend to keep going with developing both, you'll want to think about how you'll keep the two in synch.
