This property returns the form, object, or collection that contains a control.
object.Parent
The Parent property is read-only.
Most objects have either a Parent property or a Collection property that points to the object’s parent object in this object model. The Collection property is used if the parent object is a collection.
Use the Parent property to access the properties, methods, and controls of an object’s parent object.
The Parent property is useful in an application in which you pass objects as parameters. For example, you could pass a control variable to a general procedure in a module and use the Parent property to access its parent form.
