Count
This is a property of each of the OLE
collections that are part of VFP. In each case, it tells you how
many objects are in that collection.
Usage
|
nCount = colCollection.Count
|
Chalk one up for polymorphism. VFP's native collections,
like Forms and Controls, each have their own corresponding count
property with a distinct name, such as FormCount and
ControlCount. The WhateverCount property belongs to the same
object that owns the collection. For example, forms have a
Controls collection and a ControlCount property. But the
developers got smarter. The new OLE collections, like Projects
and Objects, own their own count and they all use the same name
for it. Of course, we don't need the count for a collection as
much as we used to because FOR EACH lets us loop through all the
members without worrying about how many there are.
