Here is a breakdown to Omega36 solution without writing any code.
1. Add a datacontrol to your form.
2. For its connect string property, connect to the database that you are using.
3. For its Rowsource property, select the Customer table.
4. Now, set the Data Source property of you combo box to the datacontrol.
5. If all the above steps were correct, you should see a list of the fields from the Customer table in a drop-down list of the rowsource property for the combo box. Now, like Omega36 said, set the rowsource property of the combo box to the CustomerLastName.
Hope its clear and correct.
