Advanced Form Techniques

Why This Chapter Is Important

Given Access's graphical environment, your development efforts are often centered on forms. Therefore, you must understand all the Form and Control events and know which event you should code to perform each task. You should also know what types of forms are available and how you can get the look and behavior you want in them.

Often, you won't need to design your own form because you can make use of one of the built-in dialog boxes that are part of the Visual Basic for Applications (VBA) language. Whatever types of forms you create, you should take advantage of all the tricks and tips of the trade covered throughout this chapter.

What Are the Form Events, and When Do You Use Them?

Microsoft Access traps (responds to) for over 30 Form events (excluding those specifically related to pivot tables), each of which has a distinct purpose. Access also traps events for Form sections and controls. The following sections cover the Form events and when you should use them.

Current

A form's Current event is one of the more commonly coded events. It happens each time focus moves from one record to another. The Current event is a great place to put code that you want to execute whenever the user displays a record. For example, you might want the cursor to move to the contact first name control if the user moves to a new client.

BeforeInsert

The BeforeInsert event occurs when the first character is typed in a new record but before the new record is actually created. If the user is typing in a text or combo box, the BeforeInsert event occurs even before the Change event of the text or combo box. The frmProjects form of the time and billing application has an example of a practical use of the BeforeInsert event.

AfterInsert

The AfterInsert event occurs after the record has actually been inserted. You can use it to requery a recordset after a new record is added.

BeforeUpdate

The BeforeUpdate event runs before a record is updated. It occurs when the user tries to move to a different record (even a record on a subform) or when the Records, Save Record command is executed. You can use the BeforeUpdate event to cancel the update process when you want to perform complex validations. When a user adds a record, the BeforeUpdate event occurs after the BeforeInsert event.
