Here's a little puzzle for anyone interested.


It is based on a similar item posted at the DBGuy's website 3 years ago which he was unable to explain at the time. As I like riddles, I worked out how it was done and am posting a modified version here with his permission.


The attached database contains just 2 objects

a) A table with one record

b) A form with a combo box whose row source is an empty value list


However the combo shows 4 items and a default value


Its not too difficult to recover the row source info

BUT can you work out where the combo list info is stored?

Better still can you re-create this scenario in another database?



There are no hidden objects or hidden code in this example.

It is NOT another security challenge


If you succeed, please email me your solution
