What is the difference between null and false when making a query

RE: Queries

Hi Jake

In Access queries you usually use Is Null and Is Not Null as criteria on fields that may have blank/empty cells.

False is usually used in fields that contain check boxes where the values are True (checked) and False (Not Checked)

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.
