Includes all the controls contained in an object.
Remarks
Each control in the Controls collection of an object has a unique index whose value can be either an integer or a string. The index value for the first control in a collection is 0; the value for the second control is 1, and so on. This value indicates the order in which controls were added to the collection.
If the index is a string, it represents the name of the control. The Name property of a control also specifies a control's name.
You can use the Controls collection to enumerate or count individual controls, and to set their properties. For example, you can enumerate the Controls collection of a particular form and set the Height property of each control to a specified value.
Note The For Each...Next statement is useful for enumerating a collection.
