Hi Tom

Data validation is quite a large area within access, thus I can only give a few examples of data validation, otherwise this will be an extremely long post. Basically you validate anything that is not random, for example:

The first few characters within the 1st line of an address can either be a number or a letter, then the rest must be letters.

A phone number must be number entries (you can even set a pattern for entry)

A post code must start with a letter

Hope this helps

Access tip:

Open A Combo Box Automatically

This is helpful if users need to enter large amounts of data. There are two ways to open ComboBoxes when they get the focus by using the tab keys.

When the ComboBox gets focus:

Press Alt + Down Arrow on the keyboard

For it to happen automatically, needs a bit of coding:

1. Add a combo box and a text box control to the form
2. Set the combo box's On Got Focus property to the following event procedure:

Private Sub ComboBoxName _GotFocus()

Me!ComboBoxName.Dropdown

End Sub

3. Open your form in Form View and use the TAB key to make sure it works.
