A form can become active by user action, such as clicking a form or control, or by using the Show2IF9Z3Q or SetFocus4AVBOY methods in code.

The Activate event can occur only when a form is visible.  For example, a form loaded with the LoadGU0759 statement is not visible unless you use the Show method or set the form's Visible32KNZA4 property to True.

The Activate and Deactivate events occur only when moving the focus within an application.  Moving the focus to or from a form in another application does not trigger either event.  The Deactivate event does not occur when unloading a form.

The Activate event occurs before the GotFocus32EWUCC event; the LostFocus2ZXQDAR event occurs before the Deactivate event.

These events occur for MDI child formsEXWLAX only when the focus changes from one child form to another.  In an MDI form with two child forms, for example, the child forms receive these events when the focus moves between them.  However, when the focus changes between a child form and a non-MDI child form, the parent MDI form gets the Activate and Deactivate events.

Activate, Deactivate Events Example

The example updates a status bar with the caption of the active form.  To try this example, create a form (Form1) and a new MDI form (MDIForm1).  On the MDI form, draw a picture box containing a label.  On Form1, set the MDIChild property to True.  Paste the MDIForm_Load event code into the Declarations section of the MDI form.  Paste the Form_Activate event code into the Declarations section of the MDI child form.  Then press F5.

Sub MDIForm_Load ()

   Form1.Caption = "Form #1"       ' Set caption of Form1.

   Dim NewForm As New Form1        ' Create a new child form.

   Load NewForm

   NewForm.Caption = "Form #2"     ' Set caption of new form.

   NewForm.Show                    ' Display the new form.

End Sub


Sub Form_Activate ()

   ' Set status bar text.

   MDIForm1.Label1.Caption = "Current form: " & Me.Caption

End Sub
