A recent question on Access World Forums (AWF) an OP asked whether you could get the value from a database. Reading the question I realised that he wanted to get the version number of the database:-

Hi guise, thanks a lot for your replies! It is an issue of version managing.

You can see the FULL question here:-

How can I get a Constant value from in an mde file?

I realised that one solution would be to Create a Custom Property for the actual database. I’m always creating custom properties for forms, but seldom need to at the Database level. Here was an opportunity to demonstrate creating a property at the ACCDB (mdb) level..

I wasn’t 100% sure whether it would work with ACCDE (mde) format I was pretty sure it would, but to be sure, I set about testing it.

The downloadable zip file contains 5 files, as detailed below:-

I have created two databases in ACCDB versions.
NiftyCustomDatabaseProperty.accdb
NiftyCustDatabaseProp_GetVer.accdb

I made a ACCDE version so that you can see it works with a protected database.
NiftyCustomDatabaseProperty.accde

I converted the first 2 into mdb format, I thought you might not have access to the ACCDB format
NiftyCustomDatabaseProperty.mdb
NiftyCustDatabaseProp_GetVer.mdb

When I tried to convert the mdb format to mde format I got an error message.
