Procedure Attributes - VB6
To set the Procedure ID for a procedure in Visual Basic 6.0, on the
Tools
menu, select
Procedure Attributes
. Doing so will bring up the following dialog. The dialog is shown after the
Advanced >>
key is clicked.
In addition to the items listed in the Procedure ID box -
(Default)
,
AboutBox
, and
Refresh
- you can specify that the procedure is an
Enumerator Function
by manually typing
-4
(negative 4) in the box. This apparently is a "magic number" to enable the feature. An
Enumerator Function
is used in a Collection class to allow an instance of it to be used within a For Each loop.
