Set MyObject = Nothing
Several object variables can refer to the same actual object. When Nothing is assigned to an object variable, that variable no longer refers to an actual object.
When several object variables refer to the same object, memory and system resources associated with the object to which the variables refer are released only after all of them have been set to Nothing, either explicitly by using Set, or implicitly after the last object variable referencing the actual object goes out of scope.
