Default Values for Optional Parameters

Default Values for Optional Parameters

Why Trust Us

If you ever programmed under VB4, you probably took advantage of the powerful Optional parameters. VB5 enhanced them in several ways: they can be of any type now (not only Variants), and they can appear in Property procedures. Interestingly, you can now state a default value for them:

 Property Get Value _	(Optional index As Long = 1)...End Property

You can do this without an explicit (and slower) IsMissing test:

 Property Get Value _	(Optional index As Long)If IsMissing(index) Then index = 1...End Property
