Command buttons on a toolbar are called Button objects, and all the Button
objects are stored in the Buttons Collection. This is similar to the way that
the TreeView Node objects are contained in a Nodes Collection. Each Button object
has many properties that control its appearance and functionality. These properties
can be set either at design time through the Buttons tab of the Property Pages
dialog box (see Figure 4.10) or at runtime.

of a toolbar.
As with the other controls discussed in this
chapter, individual Button objects can be referenced
by either the Index property or the Key property.
The Index property has an integer value that
refers to a button's position on a toolbar.
The first button on a toolbar will have an index
value of 1. The Key property is a unique string
expression that can be used to access a particular
button on a control.
NOTE: Key Property of a Toolbar's Button Object
The Key property of a Button object cannot contain a numeric expression even if
you convert the number using the Str$() function first. If you try to use a number
converted to a string as the key to a Button object, you will receive a runtime
error indicating an invalid key value.
