I would like to highlight a field in a table or form by changing background color when someone turns 18 years old. THis alerts me to delete them from the database of over 5000 names. I have a [DOB] date of birth field currently. Also, when I enter a new record in the database and put in the birthdate how can I if I add a new column named age(which shows their age) automatically update to show their age? Last question how do I delete a hyphen out of a number field and replace with a space for about 2000 of the 5000 records?

Look at conditional formatting.

You should NOT be storing age. As a general rule we do not store calculated values. You can use the following expression to calculate the age of a person:

DateDiff("yyyy", [Bdate], Now())+Int( Format(now(), "mmdd") < Format( [Bdate], "mmdd") )

You can use that (adding >=18) as the Condition for control you want to change the background color for.

On another note, you would do this on a form, not a table. Interaction with data should only be done through forms. And you don't have fields on a form, you have controls that may or may not be bound to fields in a table. This is a subtle but important distinction.


Finally, you would use the Replace feature under the Edit menu.
