Example

In the following example, two event procedures are attached to the LastName text box. The Enter event procedure displays a message specifying what type of data the user can enter in the text box. The Exit event procedure displays a dialog box asking the user if changes should be saved before the focus moves to another control. If the user clicks the Cancel button, the Cancel argument is set to True (–1), which moves the focus to the text box without saving changes. If the user chooses the OK button, the changes are saved, and the focus moves to another control.

To try the example, add the following event procedure to a form that contains a text box named LastName.

Private Sub LastName_Enter()
    MsgBox "Enter your last name."
End Sub

Private Sub LastName_Exit(Cancel As Integer)
    Dim strMsg As String

    strMsg = "You entered '" & Me!LastName & "' as your last name." & _
        vbCrLf & "Is this correct?"
    If MsgBox(strMsg, vbYesNo) = vbNo Then
        Cancel = True            ' Cancel exit.
    Else
        Exit Sub                    ' Save changes and exit.
    End If
End Sub
