This is straight out of the Access help files...
"Create a Visual Basic procedure"
You can set an event property (event property: A named attribute of a control, form, report, data access page, or section you use to respond to an associated event. You can run a procedure or macro when an event occurs by setting the related event property.) for a form, report, or control (control: A graphical user interface object, such as a text box, check box, scroll bar, or command button, that lets users control the program. You use controls to display data or choices, perform an action, or make the user interface easier to read.) to [Event Procedure] to run code in response to an event. Microsoft Access creates the event procedure (event procedure: A procedure that is automatically executed in response to an event initiated by the user or program code, or that is triggered by the system.) template for you. You can then add the code you want to run in response to the particular event.
Open a form or report in Design view (Design view: A window that shows the design of these database objects: tables, queries, forms, reports, macros, and data access pages. In Design view, you can create new database objects and modify the design of existing ones.).
Display the property sheet for the form or report, or for a section or control on the form or report.
Click the Event tab.
Click the event property for the event that you want to trigger the procedure. For example, to display the event procedure for the Change event, click the OnChange property.
Click Build "..." next to the property box to display the Choose Builder dialog box.
Double-click Code Builder to display the event procedure Sub and End Sub statements in the form module (form module: A module that includes code for all event procedures triggered by events occurring on a specific form or its controls.) or report module (report module: A module that includes code for all event procedures triggered by events occurring on a specific report or its controls.). These statements define, or declare, the event procedure.
Microsoft Access automatically declares event procedures for each object and event in a form or report module by using the Private keyword to indicate that the procedure can be accessed only by other procedures in that module.
Add the code to the event procedure that you want to run when the event occurs. For example, to produce a sound through the computer's speaker when data in the CompanyName text box changes, add a Beep statement to the CompanyName_Change event procedure, as follows:
*The event procedure runs each time the Change event occurs for the object.
