(IMG:style_emoticons/default/compute.gif) Access Tips: Query and Filter Criteria. When constructing a query or a filter, you need to tell Access what to look for in each field.
You do this by defining criteria - typing something (an "expression") into the Criteria cell of the query or filter grid. If you do not define any criteria for a particular field, Access assumes that you are applying no constraints and will display everything it has. This means that you only have to define criteria for those fields you are interested in. Here are some examples of the more common types of criteria. Often Access will complete the expression so that you need only type the text you want to match. The list of examples below is not exhaustive.

I then move to the next record and get the message informing me that the record has changed and do I want to save it. If I answer ‘Yes’ the changes will be saved. If I answer ‘No’ my changes will not be saved. In order to do this I added a bit of VBA code. Go into form design and bring up the form properties. Click on the top part of the form: Go up to the ‘View’ menu and select ‘Properties’: We want to look at the event properties, specifically the ‘Before Update’ event: Click the small button with the dots, the ellipsis (...), to bring up the code window: You will see the code procedure for the ‘Before Update’ event: Private Sub Form_BeforeUpdate(Cancel As Integer) End Sub Summary.
