Ref

Stores a reference to another object, data type, or value.

 

 

Variant

This property is available only at run time.

Use this property to associate the control with any Variant. If the data type is String, Ref stores a copy of the string. If the data type is a Byte array, it stores a copy of the Byte array. If the data type is an object, it increases the reference count of the object.

When Object is destroyed, and Ref holds an object reference, that object's reference count is decremented.
