You can't. However, you CAN set the Locked property to YES, so that they
cannot select anything in the list.
I assume you want to do this because you are storing the value from a
reference table in your table and you want to display the corresponding
value from the other table.
Another thing you can do is create a new, unbound textbox (I'll call it
Text5 for convienence). In the On Current event of the form, have code
something like the following:
Private Sub Form_Current()
Me.Text5 = Me.Combo1.Column(1)
End Sub
Then make your combobox invisible. You can even put your textbox right on
top of the combo.
Note: the columns property starts counting from zero, so 1 is really the
second column.
