Form.BeforeInsert event (Access)
The BeforeInsert event occurs when the user types the first character in a new record, but before the record is actually created.
expression A variable that represents a Form object.
|Cancel||Required||Integer||The setting determines if the BeforeInsert event occurs. Setting the Cancel argument to True (1) cancels the BeforeInsert event.|
Setting the value of a control by using a macro or Visual Basic doesn't trigger these events.
To run a macro or event procedure when these events occur, set the BeforeInsert or AfterInsert property to the name of the macro or to [Event Procedure].
You can use an AfterInsert event procedure or macro to requery a recordset whenever a new record is added.
The BeforeInsert and AfterInsert events are similar to the BeforeUpdate and AfterUpdate events. These events occur in the following order:
BeforeInsert → BeforeUpdate → AfterUpdate → AfterInsert
The following table summarizes the interaction between these events.
|BeforeInsert||User types the first character in a new record.|
|BeforeUpdate||User updates the record.|
|AfterUpdate||Record is updated.|
|AfterInsert||Record updated is a new record.|
If the first character in a new record is typed into a text box or combo box, the BeforeInsert event occurs before the Change event.
This example shows how you can use a BeforeInsert event procedure to verify that the user wants to create a new record, and an AfterInsert event procedure to requery the record source for the Employees form after a record has been added.
To try the example, add the following event procedure to a form named Employees that is based on a table or query. Switch to form Datasheet view and try to insert a record.
Private Sub Form_BeforeInsert(Cancel As Integer) If MsgBox("Insert new record here?", _ vbOKCancel) = vbCancel Then Cancel = True End If End Sub Private Sub Form_AfterInsert() Forms!Employees.Requery End Sub
