The Initialize event fires when an instance of the form is created
in your application.
Initialize fires just before Load the very first time the form
is loaded into memory during the application's current session. It may or may
not fire before subsequent Loads of the form, depending on what else has happened:
-
If the form was previously loaded and
then unloaded but was not un-instantiated
by having its instance set to Nothing, the
Initialize event will not fire the next
time the form is loaded.
-
If the form was previously unloaded and
then un-instantiated with
Set formname = Nothing
'(this also fires Terminate event)
the Initialize event will fire the next
time the form loads.
Forms have an Initialize event
because Microsoft wants us to see forms as programmable,
customizable object classes, and custom programmer-created
VB classes always sport built-in Initialize
and Terminate events.
You should therefore program a form's Initialize event procedure
similar to the way you'd program a custom VB class' Initialize event procedure.
That is, you should initialize custom form properties here. This might include
setting the value of Public form variables (Public variables in a form are automatically
properties of the form) or of Private variables (Private variables can store intermediate
values of properties that are implemented with Property procedures).
