Chapter 12 Quick Reference

To Do This

Process objects in

a collection

Write a For Each... Next loop that addresses each member of the collection

individually. For example:

Dim ctrl As Control

For Each ctrl In Controls

ctrl.Text = "Click Me!"

Next

Move objects in the

Controls collection

from left to right

across the screen

Modify the Control.Left property of each collection object in a For

Each... Next loop. For example:

Dim ctrl As Control

For Each ctrl In Controls

ctrl.Left = ctrl.Left + 25

Next

Give special

treatment to an

object in a collection

Test the Name property of the objects in the collection by using a For

Each... Next loop. For example:

Dim ctrl As Control

For Each ctrl In Controls

If ctrl.Name <> "btnMoveObjects" Then

ctrl.Left = ctrl.Left + 25

End If
