PropertyHandle :: SetInstance - Set basic instance for property
The function locates the area for the property handle in an instance. When defining internal structured instances this allows locating the property instance within a structure instance. This function should not be called for property handles in database instances since it may disconnect the property handle from the database instance.
Return value: Pointer to internal instance area ( void * )
Implementation details

PropertyHandle :: SetInstance ( ::Instance instance )

- Instance area
Instances do have the type of the referenced property handle (collection type). The instance contains a pointer to a properly structured instance area.
You can use the !-operator or the GetData () function to check whether the instance refers to data or not.
